In “Geologic History of North America Gets Overturned,” Live Science described how thorough the overturning was: “It’s time to redraw the map of the world during the reign of the dinosaurs, two scientists say.” The scientists, from Germany and Canada, dispute the existence of the Farallon Plate, long thought to give rise to the Rocky Mountains. Instead, they posit an archipelago, such as those in the South Pacific, instead of a continental margin. Finding stacked remnants is their justification for the overhaul. The new model is more complex in some ways, but also simpler, Nature News claimed in “How the West Was Built.” 3/16/2016 2 North American Geology All Wrong 所有北美地质学是错误 [Mitchell] Mihalynuk said the new model will make waves, as it overturns 40 years of accepted wisdom about the evolution of western North America. “It will take a while to turn people around. That intellectual ship has a lot of inertia,” he said. But for Mihalynuk, “this is one of those eureka moments.” 3/16/2016 3 North American Geology All Wrong 所有北美地质学是错误 If they are right, 40 years of accepted wisdom was really never wise at all. While this new model “makes perfect sense” to some, will it make sense to geologists 40 years from now? There’s room for reconsideration. The paper in Nature by Sigloch and Mihalynuk lists four areas of uncertainty and a fudge factor to make the model work: “This is accomplished by introducing an additional degree of freedom, an ad hoc, otherwise nonobservable, westward shift of the lithospheric shell relative to the lower mantle.” 3/16/2016 4 North American Geology All Wrong 所有北美地质学是错误 In a Perspective article in Nature, Saskia Goes said, “The tectonic history of western North America is a puzzle in which many of the pieces are mashed up or missing.” Although she believes the new seismic image data alters the reconstruction of the pieces, she described the observational data as complex: “The western margin of the North American continent, comprising the Cordilleran mountain chain that runs from Alaska to Mexico, consists of scores of continental jigsaw pieces of 3/16/2016 5 different origins, sizes and ages.” North American Geology All Wrong 所有北美地质学是错误 Goes made it clear that the new model is not fixed in stone. “Sigloch and Mihalynuk have incorporated several new pieces into the North American jigsaw, but others remain to be placed,” she said. More modeling and interpretation will be required. “The new pieces remain to be connected into a selfconsistent framework of plates with continuous and dynamically evolving boundaries,” she added, implying that the model is not self-consistent yet. Her piece 3/16/2016 6 ended with a number of remaining questions. North American Geology All Wrong 所有北美地质学是错误 Nothing in historical geology is ever as clean cut as the popular media would lead you to believe. They give the impression of progress: the new model is superior to the old. Is it necessarily? When you are dealing with scores of “jigsaw pieces” without the box cover to show you what they are supposed to look like, and no human observer around to watch what really happened, there is ample room for another 3/16/2016 7 overturn in the future. North American Geology All Wrong 所有北美地质学是错误 There is also ample room for alternative theories with different assumptions or different ad hoc, non-observable fudge factors. Some philosophers even claim an infinite number of theories can explain the same observations. However stated, theories and models like this are always “underdetermined” by data. It means that a measure of divination is required to conjure an appropriate vision that suits the 3/16/2016 8 preferences of the day. North American Geology All Wrong 所有北美地质学是错误 Overhauls also remind us that the consensus is often wrong. Forty years of false belief is what these two upstart geologists have to allege by overturning the old model: forty years of “accepted wisdom” that was foolish in their view. The new accepted wisdom awaits future self-proclaimed wise men ready to upset the applecart all over again. 3/16/2016 9 North American Geology All Wrong 所有北美地质学是错误 This is accomplished by introducing an additional degree of freedom, an ad hoc, otherwise non-observable, westward shift of the lithospheric shell relative to the lower mantle. 3/16/2016 10 Gloria Deo 愿荣耀归上帝 3/16/2016 11 Sermons From Science -- May 2013 科学布道-- 2013年5月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

The journal Nature went on a search for it in DNA. Nature’s piece, “Evolutionary Genomics: Detecting Selection” begins with hopes and worries: “Advances in population genetics and genome sequencing have made it possible to identify anonymous fragments of DNA that have undergone selection. This yields some evolutionary answers, and a panoply of 3/16/2016 13 puzzles.” The Hunt for Selection in the Genes 寻找基因的选择 Two things must be clarified before detecting natural selection. One is that artificial selection has nothing to do with it. Artificial selection is intelligently designed for a purpose; natural selection, by contrast, is unguided and purposeless. Even survival fails as a purpose; it’s only a consequence of selection, not a goal of selection. The other is that natural selection is more than variation. To differentiate itself from creationism, natural selection has to overcome small changes within a population that creationists willingly acknowledge help an organism adapt. Evolutionists need to demonstrate innovation, an undirected change providing new functional information. A mutation that produces “more of the same” effects, like a change in enzyme production, does not qualify. 3/16/2016 14 The Hunt for Selection in the Genes 寻找基因的选择 With that in mind, what did the Nature article find in its selection hunt? The authors acknowledged the “awesome power of artificial selection” directed by the mind of man, such as in dog breeding, but claimed that dogs and humans have been partners in natural selection for 10,000 years in a case of “parallel evolution.” They praised a recent paper in population genetics that “promises to revolutionize evolutionary biology, by challenging us to detect traits affected by evolution on the basis of genotype rather than an organism’s characteristics, or phenotype.” Then they praised two other papers that “rise to this challenge and show how hypotheses about an adaptive human genotype can be tested in controlled experiments.” Sounds impressive. But is this something new? What’s gone on in the past 154 years of research on natural selection? It must not have been very 3/16/2016 15 revolutionary. The Hunt for Selection in the Genes 寻找基因的选择 “Together, the three papers are a wonderful intersection between genomics, population science and experimental genetics — a synergy that has tremendous potential for teaching us more about how and why organisms evolve.” 3/16/2016 16 The Hunt for Selection in the Genes 寻找基因的选择 Unfortunately, the evidence cited in the first paper concerns genetic changes found between wolves and domestic dogs. Even the staunchest creationists put those two animals within the same created kind. The genetic changes, moreover, were in the “more of the same” category – enhanced ability to digest starch, presumably from crumbs dropped from the dog owners’ tables. Nevertheless, the authors were ecstatic that dogs and humans both produce more starch-digesting enzymes: “the same molecular mechanism has acted on similar genes in different species exposed to the same dietary pressure — a striking example of parallel evolution.” 3/16/2016 17 The Hunt for Selection in the Genes 寻找基因的选择 The other two papers merely found evidence of “selective sweeps” without tying the changes to phenotypic change. “Even when causal relationships seem obvious, caution is warranted,” the authors warned, noting a case with ambiguous results. Is detection of natural selection in human populations even possible? “Classical genetic studies are the optimal way to establish causal relationships, but in many cases these are impossible because the appropriate populations do not exist.” The third paper invented a “model organism” to tease out evidence of natural selection. Its researchers concluded that a mutation in East Asians produces thicker hair and more sweat glands; they verified that effect in mice (see 2/19/13, last section). But that’s another example of “more of the same” variation; people already had sweat glands and hair, and so did mice. 3/16/2016 18 The Hunt for Selection in the Genes 寻找基因的选择 Remarkably, this article, poised to showcase the power of natural selection, ended with ignorance: “Kamberov and colleagues’ study is an exceptional example of experimental genetics, but does it provide, as the authors suggest, a general framework for assessing candidate adaptive mutations? Genetically altered mice are a powerful experimental tool, but the extent to which recent positive selection in humans acts on pathways and amino-acid residues that have been conserved across mammalian evolution is uncertain. More importantly, it is often not clear how to investigate positively selected genomic regions for which the target gene, let alone its action, is unknown. And so a major challenge for population genomics remains the construction of meaningful null hypotheses. As Charles Darwin, the best known evolutionary biologist, once said, “It is always advisable to perceive clearly our ignorance”. 3/16/2016 19 The Hunt for Selection in the Genes 寻找基因的选择 So even though the paper they praised was “an exceptional example” of looking for natural selection, the authors of this article worried its conclusions are uncertain. Worse, (“more importantly”), it’s not even clear how to look for selection in genomic regions where the action is unknown. How does a researcher compare the findings with a null hypothesis— a baseline hypothesis that posits no effect from the cause-when “meaningful null hypotheses” are lacking? 3/16/2016 20 The Hunt for Selection in the Genes 寻找基因的选择 That’s why the summary of this triumphantly-titled article spoke of “some evolutionary answers, and a panoply of puzzles.” Even the answers, though, wouldn’t impress a creationist: no clear evidence of positive selection toward new functional information was presented. One can only hope the authors of all these papers are following Darwin’s advice to perceive clearly their ignorance. 3/16/2016 21 The Hunt for Selection in the Genes 寻找基因的选择 And they call creationists ignoramuses. OK, show us, Darwinites. Darwin believed people have bacteria ancestors. All the advances beyond bacteria for every species on earth—be they wings, eyes, or brains—are supposed to be the result of natural selection. Yet here it is, 154 years after the Origin, and evolutionists still cannot show any example in the genes bigger than starch digestion in dogs, or thicker hair and more sweat glands in certain humans (all interfertile members of the same species, Homo sapiens). The authors admit the studies are unclear. It’s appalling that the sole theory allowed to be presented in public school science classes is ignorant, not only of examples, but of ways to test them. What hath evolutionary theory wrought? A panoply of puzzles! Schools are teaching 3/16/2016 22 ignorance! The Hunt for Selection in the Genes 寻找基因的选择 If evolutionists do not perceive clearly their ignorance, those of us who do perceive it need to hold it up to their faces. We can quote Darwin for support: “It is always advisable to perceive clearly [y]our ignorance.” 3/16/2016 23 Gloria Deo 愿荣耀归上帝 3/16/2016 24 Sermons From Science -- May 2013 科学布道-- 2013年5月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

Finagle’s Rules prescribe ways to ameliorate Murphy’s Law in science. They are needed because, according to Finagle, “The perversity of the Universe tends towards a maximum.” Here are the rules: 1. To study a subject, understand it thoroughly before you start. 2. Always keep a record of data – it indicates that you have been working. 3. Draw your curves first, then plot your data. 4. If in doubt, make it sound convincing. 5. Experiments should be reproducible — they should fail in the same way. 6. Do not believe in miracles, rely on them. 3/16/2016 26 Using Finagle’s Rules in Cosmology 在宇宙学中使用哄骗的规则 The case of the impossible star: A “Methuselah” star older than the universe was reported on Space.com. That, of course, is impossible, so what did astronomers do? In order to keep current theory intact, they worked the puzzle from both ends. They increased the age of the universe, and worked to decrease the estimated age of the star from 16 billion years down to a more reasonable level, by altering theory to let it burn faster. But the new estimate is still paradoxical, because the star has to be significantly younger than the big bang to allow time for gas to condense into galaxies. “In the end, the astronomers estimated that HD 140283 was born 14.5 billion years ago, plus or minus 800 million years,” the article ends. “Further observations could help bring the Methuselah star’s age down even further, making it unequivocally younger than the universe, researchers said.” Is that further 3/16/2016 27 observations, or further finagling? Using Finagle’s Rules in Cosmology 在宇宙学中使用哄骗的规则 The case of the unwelcome supernova: Type-Ia supernovas are the “standard candles” of cosmology, critical links for determining distance and age of the universe. An upstart new type of Type-Ia has been found, potentially blurring the calibration. Called Type-Iax, it is 1/100th fainter and less energetic than classical Type-Ia supernovae, Science Daily said, and may account for a third of all Type-Ia supernovae. Couldn’t that call into question earlier estimates, making some supernova events look farther away than they were? The article didn’t say. What it did say was not particularly encouraging for standard theory. “Researchers aren’t sure what triggers a Type Iax,” for one thing. What one astronomer said was even more disconcerting: “The closer we look, the more ways we find for stars to explode.” Maybe that’s why Space.com’s headline read, “Whoa! Mini3/16/2016 28 Supernovas Discovered.” Using Finagle’s Rules in Cosmology 在宇宙学中使用哄骗的规则 The case of the anomalous good fit: Most of the science news media gave excited headlines about how a new map of the cosmic background radiation made from Planck Telescope data “confirms standard cosmology” (Science Now; see Finagle Rule #4). The Planck telescope, three times more sensitive than its predecessor WMAP, “backs sudden ‘inflation’ after the big bang,” according to Nature News. They were less excited, and more worried, about the “anomaly” in the data, the so-called “axis of evil.” Planck seems to have confirmed the presence of a preferred direction in space – a violation of the socalled “Copernican Principle” that expects every 3/16/2016 29 direction to look the same: Using Finagle’s Rules in Cosmology 在宇宙学中使用哄骗的规则 “The asymmetry “defines a preferred direction in space, which is an extremely strange result”, says Efstathiou. This rules out some models of inflation, but does not undermine the idea itself, he adds. It does, however, raise tantalizing hints that there may yet be new physics to be discovered in Planck’s data.” 3/16/2016 30 Using Finagle’s Rules in Cosmology 在宇宙学中使用哄骗的规则 Not only that, Planck found a “‘cold spot’ that covers a large area.” Space.com discussed how the new map makes the universe “older than thought” by about 100 million years, based on its calculated value of the Hubble constant. The new truth to be told in textbooks is 13.82 billion years, not 13.7, meaning that “space and time are expanding slightly slower than scientists thought.” The phrase “than thought” appears again in New Scientist: “The universe is almost perfect, 80 million years older than we thought, and maybe a little bit evil.” New Scientist suggested the anomaly might represent a bump from a neighboring universe born from “eternal inflation” putting a “bruise” on ours – a speculative notion far beyond experimental confirmation. At best, Efstathiou said, “There is less stuff 3/16/2016 31 that we don’t understand, by a tiny amount.” Using Finagle’s Rules in Cosmology 在宇宙学中使用哄骗的规则 If you don’t know how much you don’t understand, then you don’t know how much you do understand. Suppose you don’t understand 99.99% of reality. Improving that to 99.98% (“a tiny amount”) is hardly cause for rejoicing. A bad sign is when you have to conclude, based on your favored notions, that the stuff of stars and galaxies is perverse or evil. Since gas cannot be evil, the evil must reside in the minds of the theorists who fudge and finagle the data, or invent new physics, to keep their presumably righteous theories intact. When you hear a cosmologist worrying about an “extremely strange result,” ask whether it is the evidence, or the 3/16/2016 32 astronomer, that deserves the adjective.

The Nature paper is all over the news, but not all the science reporters are mentioning the most damaging admission to long ages: the preservation of organic material in fossil sauropod eggs from China, said to be 190–197 million years old from the early Jurassic – 100 million years older than the previous record. The Nature paper by Reisz et al. states, “This discovery also provides the oldest evidence of in situ preservation of complex organic remains in a terrestrial vertebrate.” Here’s how Chris Palmer 3/16/2016 35 reported it in Nature News: Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 “But it is not just the age of the fossils that is notable, the researchers say. Spectroscopic analysis of bone-tissue samples from the Chinese nesting site revealed the oldest organic material ever seen in a terrestrial vertebrate. That was surprising because the fossilized femur bones were delicate and porous, which made them vulnerable to the corrosive effects of weathering and groundwater, says Reisz. “That suggests to us that other dinosaur fossils might have organic remains,” he says. “We just 3/16/2016 36 haven’t looked at them in the right ways.” Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 The organic material is thought to be collagen. The researchers reported “organic residues, probably direct products of the decay of complex proteins, within both the fast-growing embryonic bone tissue and the margins of the vascular spaces.” They mentioned Schweitzer’s “controversial” reports of dinosaur soft tissue and corroborated them by their own methodology: 3/16/2016 37 Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 “The embryonic bones were also studied using synchrotron radiation-Fourier transform infrared (SR-FTIR) spectroscopy. In contrast to previous studies of organic residues based on extracts obtained by decalcifying samples of bone, our approach targeted particular tissues in situ (Fig. 5). This made it possible to detect the preservation of organic residues, probably direct products of the decay of complex proteins, within both the fast-growing embryonic bone tissue and the margins of the vascular spaces (Fig. 5a, b). 3/16/2016 38 Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 “This is indicated by the multiple amide peaks revealed by both infrared (1,500–1,700 cm−1 strong band from amide I and II, and 1,200–1,300 cm−1 weak band from amide III) and Raman spectroscopy (amide A peak at 3,264 cm−1) (Supplementary Figs 6.1 and 6.2). Previous reports of preserved dinosaur organic compounds, or ‘dinosaurian soft tissues’, have been controversial because it was difficult to rule out bacterial biofilms or some other form of contamination as a possible source of the organics. Our results clearly indicate the presence of both apatite and amide peaks within woven embryonic bone tissue (Fig. 5a), which should not be susceptible to microbial contamination or other post-mortem artefacts.” 3/16/2016 39 Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 References in that quote were to Schweitzer’s 2005 and 2007 papers. The Supplementary Material indicated that mathematical manipulation was necessary to see the amide peaks: “The original FT-IR amides peaks from the organic residues of Dawa (Lufeng) embryonic limb bone were convoluted, and provided relatively little detailed information (Fig.5, main document), showing a big unresolved hump around 1600 cm–1. Deconvolution is a mathematically based process to reverse the effects of convolution on recorded data. The deconvoluted peaks shown above match well known secondary structures of protein. Thus, it can be concluded that complex proteins were preserved in our specimen.” A table after this statement shows that they identified typical secondary structures of protein, such as alpha helices, beta sheets, and side chains – i.e., actual protein structures, not just amino acid “building blocks” of protein. 3/16/2016 40 Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 Science Now said the researchers “suspect” the presence of organic remains, but maintained some caution on the grounds that it’s hard to rule out contamination. “Still, if the evidence holds up, the find could finally tip the scale in favor of soft tissue preservation,” the article said. The BBC News and New Scientist didn’t mention the organic remains, but Science Daily did, based on a press release from the University of Toronto where Robert Reisz works. He said, “To find remnants of proteins in the embryos is really remarkable, particularly since these specimens are over 100 million years older than other fossils containing similar organic material.” Live Science briefly mentioned the soft tissue, and added an Image Album about the story. 3/16/2016 41 Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 National Geographic completely ignored the soft tissue evidence, but did add this detail: the eggshells were found crushed, and the bones were sorted and concentrated. Reisz presumes they were buried in a flood: “It became inundated, the embryos were smothered by sediment and water, and [they] basically rotted and fell apart,” he said. The original paper described what the site looked like: “completely disarticulated skeletal elements at various stages of embryonic development… with calcium carbonate nodules often surrounding tightly packed appendicular skeletal elements.” What does this imply? The paper continues, 3/16/2016 42 Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 “We interpret the bone bed as a para-autochthonous assemblage, formed by low-energy flooding and slow inundation of a colonial nesting site. The host sediment is a heavily bioturbated, massive siltstone, throughout which are dispersed isolated skeletal elements, eggshell fragments and the small, fossil-rich nodules of calcium carbonate. There are no preserved nest structures or uncrushed eggs.” It would seem that vulnerable, porous bones buried underwater in silt subject to bioturbation would have difficulty preserving the dinosaurs’ protein parts for 197 million years. It would also seem that a low-energy local flood by a riverbank would not leave “massive siltstone” filled with bone fragments. 3/16/2016 43 Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 Interesting that the Brits at BBC & New Scientist (as well as NG) ignored the most important part of the story, the soft tissue, as if trying to protect their national hero Charlie from embarrassment. The other articles simply assumed that soft tissue can last almost 200 million years! Why isn’t anyone seeing the obvious? Chris Palmer admitted that the eggs were “vulnerable to the corrosive effects of weathering and groundwater,” making it unbelievable that up to 197 million years passed without obliterating the proteins. Who are you going to believe, evolutionary scientists or your 44 3/16/2016 own eyes? Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 Notice also that Reisz suggested soft tissue would likely be found in other dinosaur fossils. Why haven’t they all been looking? Evolutionary theory often dictates what scientists look for and what they expect to see. Thank goodness Reisz & team made an effort to find the protein signal, even if they didn’t dwell on the implications for geological dates. This is a hot topic for creation research. Unfortunately, when they try, they are often severely criticized for (1) poor technique or (2) agenda-driven bias (example to be forthcoming). As if those problems never occur in45 3/16/2016 the secular world. Intact Protein Remnants Found in Dinosaur Eggs 发现恐龙蛋的完整蛋白质遗迹 Multiple reports now from different parts of the world are making a watertight case for soft tissue in dinosaur bones. Critics of the reports are not necessarily driven by respect for the evidence, but by fear of what it means to evolutionary geology, evolutionary dating and the whole evolution industry. 3/16/2016 46 Gloria Deo 愿荣耀归上帝 3/16/2016 47 Sermons From Science -- May 2013 科学布道-- 2013年5月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

If you were bored in science class having to learn a bunch of facts, you might have perked up if your teacher taught it the way Jonathan Osborne recommends: argue a position from available evidence. PhysOrg introduced its article by saying, “Teaching students how to argue based on available evidence engages them in the scientific process and provides a better idea of how science actually works.” 3/16/2016 49 Students Need to Argue Science, Not Memorize It 学生需要辩论科学,而不是背诵 “Earth orbits the sun. Microorganisms cause infectious disease. Plants use carbon dioxide to grow. Most of us know these scientific truths from our earliest school days. They’re accepted facts. But astronomers, microbiologists and botanists once fought for these concepts using arguments based on evidence. Science, it seems, arrives at its tenets through argument. “Science education should follow suit, says Stanford education Professor Jonathan Osborne. Teachers should help students learn to argue a position from available evidence, he says, helping them learn why we know what we know.” 3/16/2016 50 Students Need to Argue Science, Not Memorize It 学生需要辩论科学,而不是背诵 In short, Osborne wants students to think about evidence, not just be told conclusions. “In science, people argue for their ideas, in terms of the evidence that they have,” he said. “There should be more opportunities to look at why some ideas are wrong, as well as what the right ideas are.” The concept of “justification” for “right” ideas is lacking in science education, Osborne believes. His recommendations were published in the Journal of Research in Science Teaching. 50:3, March 2013. The only hard part is training science teachers to change their ways. The article led to a flurry of argumentation in the comments about what constitutes a legitimate scientific theory. Osborne was mentioned in our 5/21/2012 entry where he promoted “collaborative discourse” in the science class. 3/16/2016 51 Students Need to Argue Science, Not Memorize It 学生需要辩论科学,而不是背诵 Osborne’s ideas are good, but he doesn’t go far enough. Indoctrination into a consensus is still possible under his model, if the concepts of “evidence” and “justification” are not unpacked. This is another good time to remind readers of the course on Philosophy of Science offered by The Teaching Company, where you can see how difficult it is to justify even the simplest of scientific truths. Another worthwhile course (though flawed when it discusses intelligent design) is Science Wars: What Scientists Know and How They Know It. (Reader tip: these go on sale for 70% off from time to time). 3/16/2016 52 Students Need to Argue Science, Not Memorize It 学生需要辩论科学,而不是背诵 It’s not clear from the article if Osborne understands the problems with peer review and consensus. Does he have a Popperian view of science, or a Kuhnian view? How about the view of Feyerabend, Cartwright, or van Fraasen? Lakatos or Polanyi? What is even meant by science these days, when it covers everything from sociology to string theory? Students should learn not just to argue evidence, but to argue philosophy of science. They can’t study science without knowing what it is. Yes, normal science includes argumentation, but it can also include social pressure. Students need to know that scientific institutions, made up of fallible people who don’t know everything, can enforce conformity within popular paradigms, which regulate what questions are important53 3/16/2016 and what is meant by “evidence.” Students Need to Argue Science, Not Memorize It 学生需要辩论科学,而不是背诵 Dead ideologies can be dangerous. Positivism and scientism still parade through high schools, like zombies, without students realizing they’re dead. Let them learn to beware the zombie science teachers who say, “Scientists now know.…” 3/16/2016 54 Gloria Deo 愿荣耀归上帝 3/16/2016 55 Sermons From Science -- May 2013 科学布道-- 2013年5月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

They also exhibit more extensive diversity of abstract grammatical concepts. Chimpanzees, by contrast, just don’t get it. The famous 1970’s ape Nim Chimpsky “never grasped rules like those in a 2-year-old’s grammar.” To the researchers, “This suggests that true language learning is — so far — a uniquely human trait, and that it is present very early in development.” An article on PhysOrg, though, claimed that chimpanzees have “metacognition,” the ability to think about thinking. This was based on how they responded to a touch screen to find a hidden reward. None of them, however, were found mumbling, “I think, 57 3/16/2016 therefore I am.” Human and Animal Brains: Uniquenesses and Similarities 人类与动物大脑:独特性及异同 Math test: Another headline tells all, this time from Medical Xpress: “Despite what you may think, your brain is a mathematical genius.” Researchers at the Salk Institute were impressed that the brain appears to run an algorithm called the Gabor Transform when confronting a change of environment. The brain picks out the salient signals in both time and space, and learns to ignore others, in order to extract the maximum amount of useful information. Confronted with precision on the time channel and not the location channel, or vice versa, how does an information theorist decide the best compromise? Nobelist Dennis Gabor, who invented holography in 1971, came up with a mathematical theorem, known as a “Gabor Filter” that “helps obtain the most precise measurements possible for both qualities.” A Salk researcher said that our brains employ a similar strategy. 3/16/2016 58 Human and Animal Brains: Uniquenesses and Similarities 人类与动物大脑:独特性及异同 Music test: Several science sites reported on Canadian research that identified how the brain learns to “like” (in the Facebook sense) a new piece of music and file it in the “favorites” folder. A part of the brain called the nucleus accumbens lights up on fMRI scans when tested on various human subjects. Science Now, Live Science and Medical Xpress discussed how this shows that different human brains appear to have the same responses to a new music experience. Another Live Science article explained how this shows music is a universal language for humans. That article quoted a neuroscientist opining, without evidence, “Evolutionarily, music is something people came together to do.” None of the articles mentioned if animals have a similar response. 3/16/2016 59 Human and Animal Brains: Uniquenesses and Similarities 人类与动物大脑:独特性及异同 Your brain’s janitors: Some things go on in your brain without your knowledge, and good thing: Science Daily described how your brain does “spring cleaning.” All brains have stem cells lying in wait to be called on, ready to become nerve cells or brain cells “whenever and wherever you need them most.” To keep them in readiness, a process in the brain “clears out garbage within the cells, and keeps them in their stemcell state,” researchers at University of Michigan Medical School found. Even stem cells can generate waste. Through a well-known process called autophagy (eat myself), stem cells periodically clean house to maintain their readiness. The study was conducted on mice. 3/16/2016 60 Human and Animal Brains: Uniquenesses and Similarities 人类与动物大脑:独特性及异同 The fly, the mouse, the human: Another article on Medical Xpress claims that human, mouse and fruit fly brains have some “strikingly similar” characteristics. Al Hirth, a psychologist at King’s College London deduced this from studies of what happens when analogous parts of the brains are disrupted. A photo of the three brains side by side shows dramatic differences in size, like between a pinhead and a cantelope. The researchers found, “despite the major differences between species, their respective constitutions and specifications derive from similar genetic programmes.” Hirth believes this shows common ancestry, but he was just 3/16/2016 61 speculating: Human and Animal Brains: Uniquenesses and Similarities 人类与动物大脑:独特性及异同 “Dr Hirth from King’s College London Institute of Psychiatry says: “Flies, crabs, mice, humans: all experience hunger, need sleep and have a preference for a comfortable temperature so we speculated there must be a similar mechanism regulating these behaviours. We were amazed to find just how deep the similarities go, despite the differences in size and appearance of these species and their brains.” Dr. Hirth did not, however, find mice or fruit flies doing research to figure out how the human brain works. Furthermore, “no fossil remains of the common ancestor exist,” the article admitted. 3/16/2016 62 Human and Animal Brains: Uniquenesses and Similarities 人类与动物大脑:独特性及异同 When you see a sentence start with “Evolutionarily,…” prepare for a myth. Evolutionary psychologists and neuroscientists err when they use similarity as evidence for evolution. They fail to consider the evidence for common design. The Creator knew that a fruit fly, a mouse, and a human all need to eat, sleep, and maintain body temperature; that’s why they have similar mechanisms. Animals showcase intelligent causes in their origin; humans, uniquely, use their own intelligence to research other animals to try to understand them. We don’t see monkeys or mice building functional MRI machines and microscopes for the purpose of research. We don’t see chimpanzees using 3/16/2016 63 grammar or creating music libraries of favorites. Human and Animal Brains: Uniquenesses and Similarities 人类与动物大脑:独特性及异同 There’s enough similarity between humans and animals to show a common Creator. There’s enough uniqueness in humans to show we alone are capable of using intelligence for abstract reasoning, the enjoyment of music, the creation of music, reasoning about reality, and thinking about “thinking about thinking.” These abilities require a tool – a brain – yet reach beyond the tools into intellectual, aesthetic, and spiritual realms. These traits are common to all humans. The simplest explanation for this is that first human pair was endowed with these abilities from the beginning. The simplest account for it is the Genesis account, at which time humans were impressed with the image of God. Is there anything about the scientific articles in this entry that contradicts that account? No. Are there findings that support it? “Think” about it, and thereby help 3/16/2016 64 establish the point.

A JPL press release states that the stability of Titan’s scattered polar lakes suggests that ethane, not methane, is the primary constituent. If so, it means that methane in the atmosphere cannot last much longer. Ethane evaporates slower than methane. In the nearly nine years of observations of Titan’s surface, the lakes haven’t changed much. This suggests that heavier hydrocarbons, end products of dissociation of 3/16/2016 methane by the solar wind, predominate in the lakes.67 Titan’s Methane Still Puzzles Scientists 土卫六的甲烷仍然困惑科学家 “The lakes are also not getting filled quickly, and scientists haven’t seen more than the occasional outburst of hydrocarbon rain at the moon over the mission’s eight-plus years in the Saturn system. This indicates that on Titan, the methane that is constantly being lost by breaking down to form ethane and other heavier molecules is not being replaced by fresh methane from the interior. The team suggests that the current load of methane at Titan may have come from some kind of gigantic outburst from the interior eons ago possibly after a huge impact. They think Titan’s methane could run out in tens of millions of years.” 3/16/2016 68 Titan’s Methane Still Puzzles Scientists 土卫六的甲烷仍然困惑科学家 The “gigantic outburst” is purely speculative. There is no evidence Titan has a reservoir of methane in its interior, nor that it could erupt onto the surface. It would seem more reasonable to believe that Titan’s current methane budget is a remnant of its primordial methane. 3/16/2016 69 Titan’s Methane Still Puzzles Scientists 土卫六的甲烷仍然困惑科学家 It should be noted that scientists in the 1990s predicted Cassini-Huygens would find a global ocean of ethane on the surface from half a kilometer to several kilometers deep. If methane photolysis to ethane were occurring continuously for billions of years, it should have accumulated those vast quantities of ethane on the surface. Instead, the Huygens probe landed on relatively dry sand. 3/16/2016 70 Titan’s Methane Still Puzzles Scientists 土卫六的甲烷仍然困惑科学家 This is just an update on a story we have been following for years (1/17/02, 4/25/03,10/28/04, 7/24/06, 7/31/08, 12/1 8/08. 4/09/11, 6/15/12, 12/23/12, 1/18/13). As you can see, the problem for old-Titan believers has not been solved. If anything, it keeps getting worse. (Note: 10 million years would represent less than 1/400th the assumed age of the solar system.) The burden of proof should be on those who believe Titan is billions of years old, because the evidence clearly indicates otherwise. This means everyone should, by default, speak of Titan 3/16/2016 71 as a young world.

Cellulose is the most abundant biomolecule, but how it’s made still baffles scientists. Soon, though, you may be able to eat it. Two stories in the Proceedings of the National Academy of Sciences (PNAS) talked about cellulose: one, about how it’s made, and the other, about we might remake it into food. 3/16/2016 74 Wood You Cellulose for Starch? 木纤维素成为淀粉? Baffling Molecular Machine The first paper in PNAS is trying to tease out the structure of cellulose synthase (CESA), a complex enzyme that puts together the ingredients into the strong stacks of microfibrils that make wood sturdy and hard to digest. The team of 7 researchers said, “A 3D atomistic model of a plant cellulose synthase (CESA) has remained elusive despite over forty years of experimental effort.” The enzyme is composed of over 500 amino acids. Even this paper doesn’t have the structure all worked out. “Cellulose is nature’s most abundant renewable biomaterial and an important resource for production of biofuels that represent alternatives to fossil fuels,” the press release said, without revealing the details of how it works. 3/16/2016 75 Wood You Cellulose for Starch? 木纤维素成为淀粉? A press release from North Carolina State University where one of the researchers works shows it to look like a ring that braids the microfibrils. Lecture notes from the University of Kentucky show the machine climbing a microtubule as it removes the fructose from sucrose, weaving the microfibrils of glucose into a stiff tapestry. Box 1 of a paper from Trends in Plant Science (2012) says that 36 proteins are involved with CESA, adding, “many proteins regulate the synthesis of cellulose, either via a direct interaction… or indirectly… Mutations in any of these genes also lead to reduced cellulose content or crystallinity and cell expansion defects of roots and hypocotyls.” With the structure becoming better known, the enzyme’s processivity (method of operation) is bound to be interesting. The research team studied CESA within cotton fibers. What cotton-picker or cotton-spinner of centuries past would have thought that in his or her hands was a molecular machine that would defy the understanding of 21st century 3/16/2016 76 scientists? Wood You Cellulose for Starch? 木纤维素成为淀粉? Swords to Plowshares The second paper in PNAS describes a way to convert cellulose into starch. Cellulose, consisting primarily of glucose in chains, has proven indigestible except by bacteria within the stomachs of some herbivores. Cellulose and starch (made of glucose) have the same basic structure, differing only in the linkages between molecules. Finding a way to turn that abundant biomolecule into food would be valuable to feed a growing world population. A team at Virginia Tech found a way to do it using 5 non-natural enzymes derived from 3/16/2016 77 fungi, yeast and plant material. Wood You Cellulose for Starch? 木纤维素成为淀粉? The process yielded 30% of amylose, a linear form of starch, with the remainder available for biofuel. It’s environmentally friendly, according to Science Daily; it doesn’t require heat, chemicals or expensive equipment, and can be upscaled for commercial production. And because the enzymes can be recycled with magnetism, it doesn’t generate any waste. The abstract stated, “Next-generation biorefineries based on simultaneous enzymatic biotransformation and microbial fermentation could address the food, biofuels, and environment trilemma.” Earlier this month, PhysOrg reported on attempts to turn xylan, the world’s second most abundant biomolecule, into biofuels. It’s more challenging because of the pentose structure of its sugars gets in the way of extracting the hexose sugars in cellulose that are more easily fermented. The article spoke of this Department of Energy initiative in Biblical terms, 3/16/2016 78 likening it to turning “swords to plowshares.” Wood You Cellulose for Starch? 木纤维素成为淀粉? Like the old motivational speech “Acres of Diamonds” emphasized, people are surrounded by treasures if they just knew how to find them and use them. Here is more good Darwin-free science that can actually increase our understanding (and wonder) of the natural world, and at the same time, turn that understanding into technologies that can help humanity. 3/16/2016 79 Gloria Deo 愿荣耀归上帝 3/16/2016 80 Sermons From Science -- May 2013 科学布道-- 2013年5月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

Does it show evidence for evolution? Only to those with a good imagination. The genome was published in Nature this week. Science Now put the problem with coelacanth into perspective: “The coelacanth isn’t called a “living fossil” for nothing. The 2-meter-long, 90 kg fish was thought to have gone extinct 70 million years ago—until a fisherman caught one in 1938—and the animal looks a lot like its fossil ancestors dating back 300 million years. Now, the first analysis of the coelacanth’s genome reveals why the fish may have changed so little over the ages. It also may help explain how fish like it moved onto land 3/16/2016 82 long ago.” Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 It may, but then again, it may not. That’s the challenge facing evolutionists. Why hasn’t this fish changed under the inexorable power of natural selection for 300 million years? Why hasn’t it moved onto land? Why does it still lurk in deep underwater caves, not using those lobed fins for walking? So what’s the reason the coelacanth hasn’t evolved in 300 million years? Answer: “The coelacanth genes changed at a ‘markedly’ slower rate than those from other animals,” Science Now said, without explaining why this fish escaped a natural law of evolution. Must be some new kind of law: 3/16/2016 83 Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 “The slow rate at which the fish’s genes change demonstrates that some animals evolve more gradually than others. The coelacanth looks primitive, but looks are difficult to quantify, whereas DNA sequences are not, Ahlberg says. “The fact that their proteins evolve slowly underscores that there is a real phenomenon going on here.” A real phenomenon, like creation? Like stasis? Like falsification of evolution? Yes, there is a real phenomenon there. As for how this genome might explain how fish moved onto land, 3/16/2016 84 the scientists brought in mighty mouse: Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 “The authors located a fragment of DNA within the coelacanth’s genome that is also found in land vertebrates but not in fish without lobed fins, such as tuna, tilapia, and sharks. Because researchers cannot study live coelacanths in the laboratory, they inserted the fragment into a mouse embryo in order to learn what it does. The fragment activated a network of genes that forms bones in wrists, ankles, fingers and toes. Although it’s not yet clear what the DNA fragment’s function is within coelacanths, the authors suggest that it was key to forming the ends of limbs that helped a fishlike animal crawl out of the water.” 3/16/2016 85 Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 But the genes are HOX genes, upstream switches that control downstream development. They are not going to switch on a radius, ulna, wrist, or digits if the downstream genes aren’t there for them. These same HOX genes didn’t help the coelacanth develop limbs or crawl out of the water for 300 million years. So where is the purported “fishlike animal” where it did happen? The researchers don’t know what these genes do in coelacanths. If they did nothing, wouldn’t selection purge them instead of maintaining them for no good purpose? It’s not clear how this experiment86 3/16/2016 helps the evolutionary story. Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 Chris Woolston, writing for Nature about the genome, quoted one of the researchers (Chris Amemiya) saying, “The coelacanth is a cornerstone for our attempt to understand tetrapod evolution.” Woolston concurred that coelacanth is a living fossil, but he didn’t add anything new to the evolutionary tale, except to debunk an old one: “Ending one long-standing argument, analysis of the coelacanth genome clearly shows that it is not the closest living fishy relative to tetrapods, Amemiya says: that honour belongs to the lungfish. However, he adds, the lungfish genome is unlikely to be sequenced any time soon because it is much larger 3/16/2016 87 and more complicated than that of the coelacanth.” Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 How that helps the evolutionary story is also unclear: a more complicated, larger genome is ancestral to tetrapod genes? Why would that be? Woolston described how slow the genome evolution has been between two separated populations of the fish: “Scientists already had hints of the coelacanth’s sluggish evolution. In a 2012 study, researchers in Japan and Tanzania compared the DNA of the African and Indonesian coelacanths. Specifically, they looked at HOX genes, which help to guide embryonic development.… Even though the two species separated, by one estimate, perhaps 6 million years ago, their genes are remarkably similar. For these particular genes, the difference between the two species of coelacanth was about 11 times smaller than that between the HOX genes of humans and chimps, two species that 3/16/2016 parted ways perhaps 6 million to 8 million years ago.” 88 Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 The paper says they are 99.73% similar. To explain this non-evolution, one of the researchers offered this idea: “It is impossible to say for sure, but the slow rate of coelacanth evolution could be due to a lack of natural-selection pressure,” Kerstin Lindblad-Toh said. Natural selection is not really a pressure, though. It’s only like a bumper in a pinball game, not one of the paddles operated by the mind of the player. Woolston said that transposable elements, a form of non-coding DNA, have moved around, but Amemiya quickly added that their role in evolution is “speculative” and its significance is not clear. 3/16/2016 89 Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 So even though the genome paper said that coelacanth DNA is “a blueprint for understanding tetrapod evolution,” very little evidence supporting tetrapod evolution was offered. “The slowly evolving coelacanth” was a major subsection of the paper. Their last sentence provided only wishful thinking: “Further study of these changes between tetrapods and the coelacanth may provide important insights into how a complex organism like a vertebrate can markedly change its way of life.” 3/16/2016 90 Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 That was the 7th use of “may” in the paper, along with 5 instances of “suggest.” Evidence for positive selection was also put off into the future: “A closer examination of gene families that show either unusually high or low levels of directional selection indicative of adaptation in the coelacanth may provide information on which selective pressures acted, and which pressures did not act, to shape this evolutionary relict.” By “evolutionary relict,” they really mean something 3/16/2016 91 that didn’t evolve for 300 million years. Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 Nevertheless, the news media jumped onto the meme that the coelacanth genome “might” provide insight into evolution. The BBC News said, “The work also shed light on how the fish was related to the first land-based animals” (but it wasn’t related, the researchers had admitted). PhysOrg had a clever way to spin-doctor the anti-evolutionary evidence: it said the genome provided “Unexpected insights from a fish with a 300-million-yearold fossil record.” National Geographic focused on the notion that this fish “evolved more slowly” than other animals. Live Science used the power of suggestion in its headline, “Fish DNA Makes Limbs Sprout in Mice,” even though the HOX genes studied are far upstream of limb formation and have nothing to do with arm bones, wrists92 3/16/2016 and fingers in a fish. Coelacanth: Making the Most of an Unevolved Fish 腔棘鱼:不进化的鱼 None of the media recognized that the evidence contradicts evolutionary theory, even though the coelacanth, with its lobed fins, had been promoted as Exhibit A for evolution by Darwinists before one was found swimming in the Atlantic in 1938. If lies and misdirection were physical crimes, evolutionists would be convicted of terrorist bombings. 3/16/2016 93 Gloria Deo 愿荣耀归上帝 3/16/2016 94 Sermons From Science -- May 2013 科学布道-- 2013年5月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

Pastor Chui http://ChristCenterGospel.org 3/16/2016 ckchui1@yahoo.com 97 What’s New in the Primordial Soup? 有什么新的在原始汤? The bubbling froth percolates with ideas about how life “emerged,” each new notion trying to outdo the last in vacuity. Feel the power: Wham! goes the meteorite. From this, we are told by Science Daily, life got a helping hand to spring out of lifeless rock. “While it is generally accepted that some important ingredients for life came from meteorites bombarding the early Earth, scientists have not been able to explain how that inanimate rock transformed into the building blocks of life,” reads the teasing caption, leading us to the University of Leeds, where the “power behind the primordial soup” has been “discovered,” according to 3/16/2016 98 the headline. What’s New in the Primordial Soup? 有什么新的在原始汤? With bated breath, readers learn that “a chemical, similar to one now found in all living cells and vital for generating the energy that makes something alive,” (i.e., phosphorus) “could have been created when meteorites containing phosphorus minerals landed in hot, acidic pools of liquids around volcanoes, which were likely to have been common across the early Earth.” That alleviates “The mystery of how living organisms sprung out of lifeless rock [that] has long puzzled scientists.” Life surely would have taken that phosphorus to make ATP, right? 3/16/2016 99 What’s New in the Primordial Soup? 有什么新的在原始汤? Replace the fantasy with a bigger one: Evolutionists have this yearning for a universal tree of life that would unite all organisms in a Darwinian banner, Live Science explains, but we may need to abandon that “fantasy” for “a time before Darwinism” when multiple organisms “emerged,” giving birth to life “in a collective state.” Sounds politically correct for the far left, but we don’t know the political leanings of the idea’s advocate, Professor Nigel Goldenfeld (U of Illinois). “I like to think of early life as being more like an undifferentiated slime mold,” Goldenfeld said. “Such a communal form of life would have no meaningful family tree, because it is the community that varies in descent, not individual organismal lineages.” If the probability for a chance emergence of one viable cell is astronomically small, Goldenfeld did not explain 3/16/2016 100 how to get many separate ones all sharing together. What’s New in the Primordial Soup? 有什么新的在原始汤? What is it? Before finding how life emerged, evolutionists need to know what it is. It’s hard to define, Space.com said. Astrobiologist Chris McKay doesn’t worry about definitions; anything made of “complex, organic molecules” interests him. Like ricin? tailpipe soot? 3/16/2016 101 What’s New in the Primordial Soup? 有什么新的在原始汤? The search for what is it: The new UK Centre for Astrobiology launched this month, asking “Is there life out there?” Already 40,000 students are excited about this new initiative, the BBC News says. As is typical, the article points to Earth life and its tenacity for surviving extreme environments as evidence for life out there, but since no extraterrestrial life has been found, astrobiologists have to consider a negative answer. “The discovery of many lifeless planets across the Universe, the discovery that the Earth might be unique as a place for life, would be an astonishing discovery in itself,” said professor Charles Cockrell. “It would be a very lonely discovery, but it would be an astonishing discovery.” Clearly he was not speaking for the many theists, who expect an afterlife with their Maker and the redeemed to be anything but lonely. 3/16/2016 102 What’s New in the Primordial Soup? 有什么新的在原始汤? Life older than Earth: Taking Moore’s Law from transistors to genes and “doing the math,” two geneticists decided that life is older than the Earth, according to Live Science. This, of course, implies panspermia brought life to our planet, displacing the problem of life’s origin even further from empirical study. One of them is “99% sure it’s true” that life did not start on Earth but reserves that 1% to prove him wrong. 3/16/2016 103 What’s New in the Primordial Soup? 有什么新的在原始汤? Hope in the dead salty soup: A photo of the salty Dead Sea adorns a story in Science Daily about a Florida astrobiologist who blabs that 10 amino acids could have folded into protein-like structures in a high salt environment. See picture of the Blaber on PhysOrg. His notion, however, contradicts the “RNA World” hypothesis popular among other astrobiologists. The headline brags, “How Life May Have First Emerged On Earth.” 3/16/2016 104 What’s New in the Primordial Soup? 有什么新的在原始汤? Bleached Martians: Hopes for life on Mars have been pretty much bleached by the discovery of “pesky perchlorates” all over the surface, from the poles to Gale Crater where rover Curiosity now rolls (see Science Magazine article by Richard Kerr). New Scientist quoted the rover chief saying, “The odds of rolling up to a rock on Mars and finding organics are vanishingly small, but we’re still going to try.” Your tax dollars at work. 3/16/2016 105 What’s New in the Primordial Soup? 有什么新的在原始汤? Astrobiological enthusiasm is rising with the news that Kepler found several more “Earth-like planets” around other stars (see BBC News). But another consideration is the number of factors that must be satisfied for life, as explained in the documentary The Privileged Planet. Could those come together by chance? Science Daily took a closer look at one curious example of fine-tuning: the requirements for carbon and oxygen. “Now a team of physicists, including one from North Carolina State University, is looking at the conditions necessary to the formation of those two elements in the universe,” the article began. “They’ve found that when it comes to supporting life, the universe leaves very little margin for error.” They found that “more than a 2 or 3 percent change in the light quark mass would lead to problems with the abundance of either carbon or oxygen in 3/16/2016 106 the universe.” What’s New in the Primordial Soup? 有什么新的在原始汤? Astrobiology (n.): government welfare for storytellers. Requirements: know some scientific jargon and possess the ability to look busy. Mastery of the words emerged, could have, might have, may have, and possibly is a must. The government is an equal-opportunity employer that does not discriminate on the basis of evidence, observation, or logic. Darwin card accepted; applicants may sign up for one, but absence of a current Darwin card may trigger a background check. Prior possession of intelligent design beliefs is grounds for expulsion. This rule is enforced in order to foster the culture of storytelling astrobiologists have come to expect. 3/16/2016 107 Gloria Deo 愿荣耀归上帝 3/16/2016 108 Sermons From Science -- May 2013 科学布道-- 2013年5月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

All those new planets, but no signal—at least not one that most scientists will accept. SETI has fallen on hard times. News reports seem to waver between optimism and pessimism, with the pessimists gaining ground. Space.com said no signals have come from the trove of new earthlike exoplanets (cf. 2/08/13). Another Space.com article suggested that scientists might have to conclude we are alone, or that life is rare in the universe. “When it comes to life across the cosmos, the universe might just be an ‘awful waste of space’ after all,” 3/16/2016 110 Miriam Kramer wrote. SETI, Said He, Isn’t Ready, Said She 搜寻外星人,他说还没有准备好,她说 But this month, more earthlike planets were found by the Kepler space telescope. Optimists are optimizing at Astrobiology Magazine, asking “Are the Newly Discovered Planets Ideal SETI Targets?” All they can do is think about it and speculate, because technology to detect life optically is not far enough along. Both optimists and pessimists exchanged ideas in a meeting reported by Astrobiology Magazine, part of its “Great Exoplanet Debate” series. A candidate planet must not only be the right size in the habitable zone; it has to have a breathable 3/16/2016 111 atmosphere, the pessimists say. SETI, Said He, Isn’t Ready, Said She 搜寻外星人,他说还没有准备好,她说 Mike Wall at Space.com takes the new Kepler planet count as justification for revving up SETI. “Time Right for Next Phase in Search for Alien Life,” he headlined. Astrobiologists usually are quick to point out that alien life does not necessarily imply intelligent life. Many would be happy to find bacteria. Perhaps that’s why PhysOrg reported that some SETI Institute scientists, with NASA dollars, are going to work on the next generation of planet finders: “NASA doubles down on exoplanets and SETI institute will be part of the search.” 3/16/2016 112 SETI, Said He, Isn’t Ready, Said She 搜寻外星人,他说还没有准备好,她说 Live Science put the I back in SETI with a catalog of “13 Ways to Hunt Intelligent Aliens.” In addition to standard radio SETI, there’s optical SETI, looking for artifacts on earth or in the solar system (including alien footprints on the moon), looking for tinkering with our DNA, focused searches on the best candidate stars, hunting for life that consumes its asteroids, shows green lifestyles, or presents non-natural shapes against stars, and more. Maybe dolphins are aliens. Maybe we should wait for them to invade us. Still, the opening line is pessimistic: “Really. Where are all the aliens? We should have been probed, exterminated, assimilated, infected, invaded or abducted by now, shouldn’t we?” That’s the old Fermi paradox. Some of the speculations get ridiculous. Maybe aliens have put us on their “Do not call” list. It’s a hard sell, reporter Ian O’Neill confesses, but SETI “is one of the most profound things we, 3/16/2016 113 as a species, can do.” SETI, Said He, Isn’t Ready, Said She 搜寻外星人,他说还没有准备好,她说 Nigel Henbest at New Scientist calls SETI a detective story without a body. Reviewing a book by Paul Murdin titled Are We Being Watched?, Henbest thinks the first resort remains the best: good old radio SETI. Combing the radio sky for signals of intelligent origin would provide “the thrill that would come from answering the provocative question in the title.” 3/16/2016 114 SETI, Said He, Isn’t Ready, Said She 搜寻外星人,他说还没有准备好,她说 Want to find out if you are being watched? Want to solve the Fermi paradox? Want to engage in the most profound thing we, as a species can do? Want a method that is scientifically tractable? Want to ensure that the universe is not a waste of space? Want a thrill that would come from answering a profound question? Want verifiable answers, not idle speculation? Want a nonquestion-begging, non-self-refuting approach? Want assurance that the answer is real? Then read the artifact left by Extra-Terrestrial Intelligence. Start with the first chapter and verse, Genesis 1:1, and 3/16/2016 115 continue on to the grand finale.

Periodically, another attempt is made to explain the one-handedness of life’s amino acids. The problem for materialists, explained in our online book chapter 3, is that only 100%-pure onehanded proteins will work, but the probability of getting pure one-handedness (“homochirality”) by chance is vanishingly small (chapter 4). The latest article addressing this problem 3/16/2016 118 on PhysOrg admits it: Latest Attempt to Explain Homochirality Underscores the Problem 最新尝试解释同手性突出问题 “Life on Earth is made of “left-handed amino acids (L-amino acids)”. The question of why organisms on Earth consist of L-amino acids instead of Damino acids or consist of D-sugar instead of Lsugar is still an unresolved riddle. In other words, a major mystery of life on Earth is that organisms are exclusively made up of lefthanded amino acids. Therefore, the effort to solve this problem is one of the biggest in research into the origins of life, a subject that remains enveloped in mystery.” 3/16/2016 119 Latest Attempt to Explain Homochirality Underscores the Problem 最新尝试解释同手性突出问题 The homochirality problem is enormous: “Origin-of-life theories often ignore the homochirality problem, even though the question is critical to the origin of life,” the article states. All known physical processes lead to mixed-handed (“racemic”) collections. Since the two forms behave the same chemically and thermodynamically, how can they be separated? Only life seems capable of producing pure one-handed sets. 3/16/2016 120 Latest Attempt to Explain Homochirality Underscores the Problem 最新尝试解释同手性突出问题 Previous attempts have tried to discover physical factors that might lead to a preference for one hand over the other (“enantiomeric excess”), but they have only achieved differences of a few percent. PhysOrg explained the leading multi-step hypothesis for separating the hands: (1) Find stellar sources of circularly polarized light that might preferentially destroy one hand or convert it to the other; (2) Have the amino acids delivered to Earth via meteorites; (3) Purify the one hand further in shallow basins undergoing cyclic periods of wetting and drying. 3/16/2016 121 Latest Attempt to Explain Homochirality Underscores the Problem 最新尝试解释同手性突出问题 Now, astronomers at the National Observatory of Japan have detected the highest ever circular polarization excess from a star: 22%. Their paper was published in The Astrophysical Journal Letters. This has “implications for the origin of homochirality,” the PhysOrg headline reads NASA’s Astrobiology Magazine reproduced the press release verbatim, categorizing it as a “Hot topic,” headlining it, “Star– and Planet-Forming Regions May Hold Key to Life’s Chirality.” If so, the implications are pretty weak, and the key hard to find, since polarization only addresses half of the first step in the chain. It is not known how effective circularly 3/16/2016 polarized light is in causing changes to amino acids.122 Latest Attempt to Explain Homochirality Underscores the Problem 最新尝试解释同手性突出问题 The finding also requires that most of life’s amino acids were sent to Earth on meteorites – a controversial claim. Even then, the enantiomeric excess would likely be small, and exist only in tiny locales (shallow pools) that reduce the lab space for life’s origin. But unless a growing protein chain is 100% pure with one hand, it won’t work. A generous scenario with 22% excess (assuming the amino acid population trends with the polarized light excess) is far too small to help, even if origin-of-life researchers could figure out a way for the amino acids to link up naturally (they prefer to separate in water). Homochirality is not the only mystery. “The history of star and planet formation and the origin of life are still a mystery,” too, the article confessed. 3/16/2016 123 Latest Attempt to Explain Homochirality Underscores the Problem 最新尝试解释同手性突出问题 Could the pure one-handedness in life be bona fide evidence for intelligent design? Louis Pasteur, the man who discovered homochirality, thought so. For more than a century this problem has baffled materialists. They’ve been trying to relegate this to a god-of-the-gaps argument for too long. One can’t keep using that excuse forever. If the gap keeps getting wider, or if the evidence creates a positive argument for design, there comes a time to turn that excuse around and accuse materialists of materialism-of-the-gaps, the faith that somehow, sometime, a solution will emerge. But why must materialism be the default position? Scientists cannot live in the land of mystery for decades and still call it science. If the evidence points124to 3/16/2016 design, so be it.

Pastor Chui http://ChristCenterGospel.org 3/16/2016 ckchui1@yahoo.com 126 Evolutionists Don’t Understand Their Own Theory 进化论者不明白自己的理论 If evolutionists and reporters stuck to the essence of neo-Darwinism, many of their claims would never reach the press. Darwin attempted to describe a natural mechanism (natural selection) that would generate the entire tree of life, with all its diversity. Neo-Darwinism identifies the source of variation as mutations. The essence of Darwinian theory is that the process is unguided, with no goals or purposes. Many evolutionists and their press agents seem to 3/16/2016 127 forget this. Evolutionists Don’t Understand Their Own Theory 进化论者不明白自己的理论 Artificial selection is not evolution. A common fallacy is to assume artificial selection is the same as natural selection. Artificial selection, though, comes from goals, purposes and plans of people; it’s a form of intelligent design. One form of this fallacy is “computer evolution” – programming a computer to simulate the evolutionary process. Science Daily reported on attempts to do this at Cornell’s “Creative Machines Lab” (a tip-off that this is not about Darwinism). The reader is told, “A research team led by Cornell University’s Creative Machines Lab has created a computer algorithm that can be used to witness virtual creatures evolving their squishy, muscle-like features in order to teach themselves to walk.” All the bold words in that sentence violate Darwinian principles, yet the article claims that the experiment demonstrates “the power of 3/16/2016 128 evolution to create counterintuitive designs.” Evolutionists Don’t Understand Their Own Theory 进化论者不明白自己的理论 Change within species is not evolution. Medical Xpress tells readers this profound observation: “Evolving genes lead to evolving genes.” Other than being a tautology, the headline leads into a story with no evidence for the origin of species. The Wellcome Trust and Sanger Institute went looking for evidence of positive selection in a single gene named FOXP2, implicated in human speech: “Have these evolutionary changes in FOXP2 function or expression exposed its target genes to novel selective pressures?” The variations they found, however, only exist in human populations that are all members of Homo sapiens, one interfertile species. Even the strictest creationists allow 3/16/2016 129 for that kind of change. Evolutionists Don’t Understand Their Own Theory 进化论者不明白自己的理论 Microevolutionary change is not evolution. John Thompson of UC Santa Cruz has a new book out, Relentless Evolution, that alleges “species evolve relentlessly and that evolutionary changes occur at a surprisingly rapid pace.” Yet apparently, the changes he speaks of are occurring within species, not from one species to another. According to PhysOrg, he describes the Darwinian mechanism correctly as aimless. He states that “Much of adaptive evolution does not lead anywhere,” yet the article speaks only of continual microevolutionary changes within species that would make a creationist yawn. “These continual microevolutionary changes keep populations in the evolutionary game as they interact with other species that are themselves constantly evolving,” Thompson says. “These seemingly aimless meanderings are the essential dynamics of evolution, with directional change and speciation as occasional outcomes.” Yet nowhere does he describe the origin of species or any kind of directional change leading to a new organ or function. 3/16/2016 130 Evolutionists Don’t Understand Their Own Theory 进化论者不明白自己的理论 Behavior within species is not evolution. New Scientist turns classical Darwinism on its head with this headline: “Survival of the shyest: Timidity’s surprising benefits.” Reporter Leslie Evans Ogden does her best to show that some humans, salamanders and birds appear more successful without being assertive, but nowhere does she describe a species becoming another species. Ogden claims that evolution favors both boldness and shyness, but nowhere escapes the tautology of defining fitness in terms of survival. Even if she makes a case that shyness has its advantages, nothing in the proposition supports neo-Darwinism. 131 3/16/2016 Evolutionists Don’t Understand Their Own Theory 进化论者不明白自己的理论 Evolvability is not evolution. The ability to evolve does not, ipso facto, mean that bacteria evolved into humans. But that’s not the only puzzle in Science Daily’s headline: “Computer Scientists Suggest New Spin On Origins of Evolvability: Competition to Survive Not Necessary?” Here’s two more: the reference to computer science, and the denial of classical Darwinian competition as a necessary condition for the origin of species. Anything dependent on a computer “algorithm” is suspect from the starting line as a model for how an aimless, purposeless process could originate new organs and functions. A researcher from the University of Central Florida stated, “An important implication of this result is that traditional selective and adaptive explanations for phenomena such as increasing evolvability deserve more scrutiny and may turn out unnecessary in some cases.” Maybe he should come back when he knows something. In the meantime, nothing in the article 3/16/2016 132 demonstrated the origin of species by unguided processes. Evolutionists Don’t Understand Their Own Theory 进化论者不明白自己的理论 Purpose is not evolution. The oxymoronic phrase “Evolutionary Purpose” appears in a headline on Live Science that gets even more bizarre. Reporter Charles Choi writes, “Birds can hold their wings high because of the strange way they crouch, and now scientists say the origins of this folded posture may provide insight into the evolution of their flight.” A cartoon of a perching T. rex in a tree adds to the fantasy. It doesn’t matter that some dinosaur’s crouching posture is similar to that of birds; the burden of proof Choi set for himself is to show that an aimless process led to avian flight. Humans and kangaroos can crouch in a similar way but are not evolving hollow bones, avian lungs or wings. Choi commits the fallacy that evolution has an aim when he says “birds evolved to crouch.” Those two words should never go together. An aimless, purposeless process cannot “evolve to” do anything. Besides, Choi is not sure if it happened gradually or suddenly, indicative of an absence of scientific explanation. 3/16/2016 133 Evolutionists Don’t Understand Their Own Theory 进化论者不明白自己的理论 Let’s hold evolutionists’ feet to the fire. Insist on these rules: No teleology. No aim. No intelligence. No purpose. No assuming evolution is a fact. No microevolution. No computers. No intelligent design, such as with artificial selection. Show new species or kinds, not just variation within a species: it needs to surpass the kinds of changes creationists already accept. Show innovation toward new function, not just horizontal change. With those rules, the Darwin industry would dry up, because few (if any) are the papers that try to deal honestly with the facts of nature, relying only on the principles of Darwinian evolutionary theory. But, of course, if they are principles, they undermine evolutionary assumptions in the first place, because principles rely for their existence on the immaterial realm of concepts–ideas–propositions. Maybe if evolutionists grunted 3/16/2016 134 like chimps they would make more sense.

Why, then, is it controversial for a physicist to claim that time is real? Live Science describes the ideas of Lee Smolin, who “controversially” claims that time is not an illusion, but a fundamental aspect of the universe. The question opens up a “meta-law dilemma” about whether laws of nature are inside or outside of time. If outside, Smolin argues, they have no meaning. The question also bears heavily on the nature of the Second Law of Thermodynamics, and why it presents an asymmetrical “arrow of time.” In his article for New Scientist, Smolin said, “It might be a funny thing to say, but the idea that time is real requires a radical departure from the standard paradigm of physics.” Nature reviewed Smolin’s new book, Time Reborn: From the Crisis in Physics to the Future of the 3/16/2016 137 Universe. Major Cosmic Questions Remain Unanswered 宇宙的主要问题仍然未决 Theory of massive star formation encounters surprise: Science Daily reported that astrophysicists were surprised when a massive star disobeyed theory. Standard candle isn’t: PhysOrg reported the possibility that gravitational lenses could make Type 1a supernovae, the leading cosmic distance indicators, much brighter than they are. The implications of this realization for estimating the size and age of 3/16/2016 138 the universe were not explored. Major Cosmic Questions Remain Unanswered 宇宙的主要问题仍然未决 The antimatter puzzle: The BBC News, Live Science and Science Daily all reported that the Large Hadron Collider may have found a case of matter-antimatter asymmetry for a particular form of matter (the Bs meson) and its antiparticle. It’s not enough to explain the predominance of matter in our universe though. Jason Palmer at the BBC writes, “but puzzle abides.” Science Daily quoted the physicists saying that the observed asymmetry is “too small to account for the 3/16/2016 139 matter-dominated Universe.” Major Cosmic Questions Remain Unanswered 宇宙的主要问题仍然未决 Grand finale came first: Another observation supports the surprising finding that the universe underwent extraordinary periods of star formation in its infancy (01/08/2002, 09/21/2005,04/02/2009, 12/17/2010). Big bang theory posits that the universe began in a highly smooth state, but Science Daily wrote, “Astronomers using a worldwide collection of telescopes have discovered the most prolific star factory in the Universe, surprisingly in a galaxy so distant that they see as it was when the Universe was only six percent of its current age.” Another example, “a dust-obscured massive maximum-starburst galaxy at a redshift of 6.34,” was reported by Nature: “it seems that environments mature enough to form the most massive, intense starbursts existed at least as early 3/16/2016 140 as 880 million years after the Big Bang.” Major Cosmic Questions Remain Unanswered 宇宙的主要问题仍然未决 Dark matter moment of truth: Science Magazine stated that the “dark matter mystery” is nearing its “moment of truth.” Dark matter is supposed to be much more plentiful than visible matter, according to leading theory, but has eluded all detection. One team thinking it has a potential detection of WIMPs (weakly interacting massive particles, a theoretical kind of dark matter) is not ready to announce it. Others are urging caution because of other 3/16/2016 141 falsified claims in the past. Major Cosmic Questions Remain Unanswered 宇宙的主要问题仍然未决 Higgs vs inflation: Nature reported that the properties of the newly-discovered Higgs boson “could spell trouble for leading Big Bang theory.” Astronomer Paul Steinhart believes data from the Planck telescope “introduce new, serious difficulties” for the popular hypothesis that the universe underwent exponential expansion in the first fraction of a second after the big bang. 3/16/2016 142 Major Cosmic Questions Remain Unanswered 宇宙的主要问题仍然未决 A simple, ignored question: Back in January, in Live Science, Joel Shurkin asked, “Where did the universe’s magnetism come from?” That question is rarely addressed. The big bang would have begun with no magnetism, he says: “In the beginning there was no magnetism.” Today, though, it is one of the most powerful forces in stars and galaxies. Any incipient fields after the big bang should have cancelled each other out. Shurkin entertained a theory by one German physicist, Reinhard Schlickeiser, who thinks it began very weak until iron evolved in stars, then current flows magnified it. “You have to have something to start from,” his partner said, but that begs the question of where the something came from. 3/16/2016 143 Major Cosmic Questions Remain Unanswered 宇宙的主要问题仍然未决 Inconstant speed of light: It’s not just creationists who put forth the idea that the speed of light is not constant. Live Science entertained ideas from two physicist teams who propose it, even though their estimates of the amount of change are slight. Still, it shows that fundamental ideas unquestioned since Einstein can still be questioned. 3/16/2016 144 Major Cosmic Questions Remain Unanswered 宇宙的主要问题仍然未决 Hubris nonetheless: Given the amount of mystery remaining in physics and cosmology about the most basic questions, it seems blatantly hubristic for Stephen Hawking to continue claiming that “the big bang didn’t need God,” as Space.com reported. He’s assuming there even was a big bang. On April 16, long lines waited to hear him at Caltech mock God and religion. He even fancies himself a prophet. He said, “I don’t think we will survive another thousand years without escaping our fragile planet.” Fortunately for him, he won’t have to face 3/16/2016 145 accusers in the year 4013. Major Cosmic Questions Remain Unanswered 宇宙的主要问题仍然未决 Never confuse the observable, repeatable, testable science that gives us cell phones with the unverifiable speculation emerging from the mouths and keyboards of secular scientists who don’t know what they’re talking about, who keep making theoretical claims that get falsified by new observations, and who intrude into metaphysical questions they are not philosophically prepared to approach. Their only qualification lies in the 3/16/2016 146 sophistication of their ignorance.

Pastor Chui http://ChristCenterGospel.org 3/16/2016 ckchui1@yahoo.com 148 Saturn’s Rings Impacted by Meteoroids 流星冲击土星的光环 Cassini has observed clouds of dust from meteoroids hitting the rings. The data will “impact” theories of the rings’ origin and age. New observations have shown dust clouds from four impacts on Saturn’s rings (see JPL press release). One impact was observed twice, about 25 hours apart. The impacts were found in all three major rings: A, B, and C. The ejecta clouds are thought to have been observed between 1 and 50 hours after the impacts. According to National Geographic, streams of meteors must be hitting the rings more often than thought. A paper by Cassini scientists was published in Science Magazine. National Geographic waxed philosophical, saying, “The hope in the science community is that insights into these ring impacts may also shed light on the rings’ puzzling origins.” That sentence cloaks the real problem: impacts are destructive, not constructive. Jeff Cuzzi, long time ringmaster and co-author of the 3/16/2016 149 paper, expressed concerns in the press release: Saturn’s Rings Impacted by Meteoroids 流星冲击土星的光环 “Saturn’s rings are unusually bright and clean, leading some to suggest that the rings are actually much younger than Saturn,” said Jeff Cuzzi, a co-author of the paper and a Cassini interdisciplinary scientist specializing in planetary rings and dust at NASA’s Ames Research Center in Moffett Field, Calif. “To assess this dramatic claim, we must know more about the rate at which outside material is bombarding the rings. This latest analysis helps fill in that story with detection of impactors of a size that we weren’t previously able to detect directly.” 3/16/2016 150 Saturn’s Rings Impacted by Meteoroids 流星冲击土星的光环 The impactors are estimated to be between a centimeter and several meters in diameter. If a rain of dusty debris like this has been going on for billions of years, the rings should appear darker than they are. Furthermore, since they carry away more mass than they add, they have been eroding the rings for a long time according to current beliefs about Saturn’s age. Pollution and erosion are not helping keep Saturn’s 3/16/2016 151 rings old. Saturn’s Rings Impacted by Meteoroids 流星冲击土星的光环 Another clue for a high impact rate is the “ring rain” that descends onto Saturn’s equatorial bands. Science Daily said that “more charged particles fall than thought” from water ions originating in the rings. Are the charged particles coming from impacts hitting the rings? What other process could be sending material from the rings onto Saturn? The article didn’t say. In any case, this is another erosive process, it appears. The paper in Science said that the estimated impact rate, though significantly higher “at face value” than before, is too uncertain to know for 3/16/2016 152 sure: Saturn’s Rings Impacted by Meteoroids 流星冲击土星的光环 “Our results are higher than the extrapolation by one or two orders of magnitude (Fig. 4); at face value, especially if this increase is also reflected in submillimeter-to-millimeter-size particles, then pollution and erosion rates due to interplanetary meteoroids might be higher than have been thought. However, gravitational focusing enhances the flux at Saturn’s rings by a factor of 4 to 40, and the sensitivity of rings to a two-directional flux yields another factor of 2, so our results may corroborate the previous extrapolation after all.” 3/16/2016 153 Saturn’s Rings Impacted by Meteoroids 流星冲击土星的光环 (By extrapolation, the authors refer to the prior habit of estimating impact rates for the outer solar system to be similar to rates in the inner solar system.) Better observations to constrain the impact rate will be possible when the Cassini spacecraft approaches its end of mission (2017), when it is slated to make series of “high dives” over the rings and into the gap between the D ring and Saturn. 3/16/2016 154 Saturn’s Rings Impacted by Meteoroids 流星冲击土星的光环 If this were the only problem in the Saturn system facing the moyboys (believers in “millions of years, billions of years”), it would be worrisome for them. But then you have Titan’s atmosphere, the Titan ethane problem, the Enceladus geysers, delicate rings, and other matters that, taken together, could title a book, “Billions of years: a theory in crisis.” Prediction: future measurements of impact rates on Saturn’s rings will prove 3/16/2016 155 higher than expected.
