http://hyperphysics.phy-astr.gsu.edu/hbase/index.html A useful encyclopedia of physics concepts, with clear explanations organized around connected concepts. Some of the best information out there is in the form of blogs written by well-informed people. For general physics: http://backreaction.blogspot.com/ The blog of theoretical physicist Sabine Hossenfelder, with short video explanations accompanying her posts. She has excellent explanations of basic concepts in physics, as well as discussions of big questions at the cutting edge of physics discovery. https://math.ucr.edu/home/baez/ Excellent resources by John C. Baez, a mathematical physicist, with advice on how to approach various topics in advanced math and physics. https://www.quantamagazine.org/ A collection of excellently written articles about topics at the cutting edge of research. https://nautil.us/ Another excellent science magazine. https://www.brainpickings.org/ Beautiful and inspiring collection of articles about the search for a meaningful life, with an emphasis on the wonder and beauty of scientific discovery, the links between science and art, and the stories of lesser-known contributors to science, philosophy and art. Some blogs about the connection between energy, climate an economy. These are contentious topics which tend to raise strong emotions in conversations, and the posts in these blogs should be taken as a starting point for a debate, not the final word. http://energyskeptic.com/ This is a collection of discussions on the far-reaching impacts of fossil fuels on industrial society and contains eye-opening discussions about alternative sources of energy and their technical potential and limitations. https://dothemath.ucsd.edu/ Another blog with back-of-the-envelope calculations related to energy and climate. It is a good example of how complex topics can be broken down and approached through basic mathematics and physics. However, it’s important to keep in mind that equations are abstractions of the real world, and they may neglect factors that turn out to be important. Whenever using a mathematical model, it’s important to be aware of its limitations. https://judithcurry.com/ Open discussion on the state of climate science, with weekly roundups of links to important research and articles on climate science, energy, policy and social issues in science. https://wattsupwiththat.com/ A blog about meteorology, written by a retired meteorologist. Some blogs about quantum physics, nanophysics and condensed matter physics (basically, what happens when you take a lot of interacting particles and stick them side by side). Despite not getting as much popular media attention as astrophysics, cosmology and high-energy particle physics, condensed matter is one of the largest field of research, with some beautiful theory and experiments, as well as extremely practical applications. https://thiscondensedlife.wordpress.com/ https://condensedconcepts.blogspot.com/ https://nanoscale.blogspot.com/ For quantum computing, the best blog is Scott Aaronson’s blog “Shtetl-optimized”. He is also an example of a person who manages to stay a mensch in the cut-throat world of academia and social media, and he has several personal posts about his experience being a target of online shaming. https://www.scottaaronson.com/blog/ Also check out Michael Nielsen, a physicist who started in quantum computing, went on to do research at Google, and became a writer. He interests span physics, cognition, computing, artificial intelligence, and the sociology of knowledge discovery. https://michaelnielsen.org/ For excellent articles about the pharmaceutical industry, check out the blog of medicinal chemist Derek Lowe https://blogs.sciencemag.org/pipeline/ A good resource for statistics and data analysis is Cosma Shalizi, a professor of statistics at Carnegie Mellon University http://bactra.org/ Some scientific tools used in math and physics can also be helpful in studying complex systems like ecology. One of the best blogs on ecology, with an emphasis on quantitative modeling: https://dynamicecology.wordpress.com/ Webcomics on science and math: https://redpenblackpen.tumblr.com/ comics about the scientific life, by a biologist https://mathwithbaddrawings.com/ a comic started by a high school math teacher, with witty comics and really good math explanations. https://phdcomics.com/ (a comic about science and the life of scientists within academia, by a mechanical engineering PhD at Stanford) https://xkcd.com/ a comic about math, physics and computers, drawn by an engineer at NASA. https://ophysics.com/e2.html elastic collisions simulation
