Patrick McCauley Physics 105 Reading List 1 Audience: Someone entering high school and interested in science A. Article with a Science Theme M. Turnbull, “Where is Life Hiding?,” Astronomy, 58-63 (Oct. 2006). B. Background Information and Further Readings, with Justifications Background Information: “The Solar System,” DVD Films for the Humanities & Sciences (2000). Call number: Carrier DVD 684 Justification: This video covers the Earth’s solar system with information about the Sun, each of the planets, and how the system formed. It is important to understand the workings of our own solar system, the only system known to harbor life, when examining other solar systems in the search for extraterrestrial life. Additionally, this video was found in the university library and was produced by an established organization for educational films. Background Information: B. Dorminey, Distant Wanderers: the Search for Planets Beyond the Solar System, 1st ed. (Copernicus Books, New York, 2002). Call number: Carrier QB820 .D67 2002 Justification: This book examines the most current and generally accepted theories about how extrasolar planets form, and includes the relatively current progress made in the search for extrasolar planets as well as techniques for discovering such planets. Furthermore, the book was found in the university library, was published by an established scientific publisher, and is at a reading level appropriate for high school and college students. Further Reading: S. Shostak, “Drake’s Brave Guess,” Discover (May 2006). Justification: This article details the Drake Equation, which is an estimate to the number of civilizations in our galaxy that we might come into contact with. Frank Drake (University of California) was a pioneer in the search for extraterrestrial life and his equation, which is based on known astronomical facts and estimations, has become an accepted scientific estimate that is open to interpretation. The article was found in an established scientific journal that is at an appropriate reading and detail level for the specified audience. Further Reading: G. W. Marcy, “The New Search for Distant Planets,” Astronomy, 30-37 (Oct. 2006). Justification: This article examines the most current and successful detection methods for extrasolar planets and provides information about the habitable zones of stars (distance from star where liquid water exists). Furthermore, the article includes the most current discoveries of extrasolar planets and also the most promising places for the search for life to continue. Finally, the article was written by a current researcher in the field and was published by an established publisher in the same issue as the initial chosen article. C. Excluded Source and Justification Excluded Source: A. P. Boss, “How Do You Make a Giant Exoplanet?,” Astronomy, 3843 (Oct. 2006). Justification: Although this article has valuable information about the formation of giant extrasolar planets and was published in the same issue as the initial article, it focuses primarily on extremely large gaseous planets that are unlikely to harbor life. Despite this, most of the extrasolar planets discovered to date are giants such as those described in this article because current detection methods are based on the examination of gravitational effects, which can only detect planets with large masses. Since these planets are unlikely to support life, which is the primary focus of the initial article, this article is excluded from the reading list. Reading List 2 Audience: A first-year college student majoring in science A. Article with a Science Theme M. Turnbull, “Where is Life Hiding?,” Astronomy, 58-63 (Oct. 2006). B. Background Information and Further Readings, with Justifications Background Information: T. R. Stuart, Destiny or Chance: Our Solar System and Its Place in the Cosmos (Cambridge University Press, Cambridge, 1998). Call number: Carrier QB501 .T248 1998 Justification: This book covers the Earth’s solar system, including information about the sun, each of the planets, the formation of the solar system, and the solar systems place in the cosmos. The information is covered in greater detail than in the video chosen for the high school reading list and is presented at a level appropriate for college students. Furthermore the book was written by an active planetary scientist, was found in the university library, and was published by Cambridge University Press, an established publisher. Background Information: B. Dorminey, Distant Wanderers: the Search for Planets Beyond the Solar System, 1st ed. (Copernicus Books, New York, 2002). Call number: Carrier QB820 .D67 2002 Justification: This book examines the most current and generally accepted theories about how extrasolar planets form, and includes the relatively current progress made in the search for extrasolar planets as well as techniques for discovering such planets. Furthermore, the book was found in the university library, was published by an established scientific publisher, and is at a reading level appropriate for high school and college students. Further Reading: C. H. Lineweaver and T. M. Davis, “Does the Rapid Appearance of Life on Earth Suggest That Life is Common in the Universe?,” Astrobiology 2, 293-304 (2002). Justification: This article examines the theory that if life developed relatively rapidly on Earth, then life must be common elsewhere in the universe. The article includes information about the Drake Equation, an estimation for the number of civilizations in our galaxy that we might come in contact with, but at greater detail and specificity than the Discover article on the high school reading list. Additionally, the article was written by current university researchers and published in an established scholarly journal. Further Reading: G. W. Marcy, “The New Search for Distant Planets,” Astronomy, 30-37 (Oct. 2006). Justification: This article examines the most current and successful detection methods for extrasolar planets and provides information about the habitable zones of stars (distance from star where liquid water exists). Furthermore, the article includes the most current discoveries of extrasolar planets and also the most promising places for the search for life to continue. Finally, the article was written by a current researcher in the field and was published by an established publisher in the same issue as the initial chosen article. This article qualifies for both the high school and college level reading lists because it provides valuable information that is presented at an appropriate detail and specificity level for both audiences. C. Excluded Source and Justification Excluded Source: "Extrasolar Planet." Wikipedia. 21 Sept. 2006. Wikimedia Foundation, Inc. 24 Sept. 2006 <http://en.wikipedia.org/wiki/Extrasolar_planet>. Justification: Although this webpage contains very valuable background information and includes an extensive reference list, the name and credentials of the author(s) is not included and the information can potentially be altered by a non-credible source. Reading List 3 Audience: A science faculty member at a college or university A. Article with a Science Theme M. Turnbull, “Where is Life Hiding?,” Astronomy, 58-63 (Oct. 2006). B. Background Information and Further Readings, with Justifications Background Information: J. F. Kasting, D. P. Whitmire and R. T. Reynolds, “Habitable Zones Around Main Sequence Stars,” Icarus 101, 108-128 (1993). Justification: This article provides a model for estimating the habitable zones around stars, or the region around a star in which liquid water could be present. The concept of habitable zones is central to the search for extraterrestrial life as it is important to understand the constraints by which the search must adhere. This article was written by three researchers in the field and was published in an established scientific journal. Background Information: J. S. Kim et al., “Formation and Evolution of Planetary Systems: Cold Outer Disks Associated with Sun-Like Stars,” Astrophys. J. 632, 659-669 (2005). Justification: This article presents the discovery debris belts around two stars that seem to confirm the accumulative model of planetary formation, which is the leading theory for how rocky planets like Earth are formed. The article also provides an explanation for the theory, which is important background knowledge with regard to the search for extraterrestrial life. The article was authored by a large group of researches from several leading universities around the world and was published in an established scientific journal. Further Reading: F. D. Drake, Intelligent Life in Space (Macmillan, New York, 1962). Justification: This is the original essay in which Frank Drake proposed his equation for estimating the number of civilizations in our galaxy that we might make contact with. The equation has since become famously known as the “Drake Equation” and has provided momentum and credibility to the search for extraterrestrial life. Due to the density of the article in terms of scientific terminology it was not appropriate for inclusion in the high school and college student level reading lists, but is certainly appropriate for a college faculty member. Further Reading: M. Turnbull and J. C. Tarter, “Target Selection for SETI. A Catalog of Nearby Habitable Stellar Systems,” Astrophys. J. Supplement Series 145, 181-198 (2003). Justification: This article catalogs nearby stellar systems that appear promising in the search for extraterrestrial life. The article provides specific examples of the types of star systems that researchers are examining, as well explanations as to why those systems are being considered for examination with the SETI Radio Telescope. Furthermore, the selection was coauthored by the same author as the initial chosen article and was published in an established scientific journal. C. Excluded Source and Justification Excluded Source: T. R. Stuart, Destiny or Chance: Our Solar System and Its Place in the Cosmos (Cambridge University Press, Cambridge, 1998). Call number: Carrier QB501 .T248 1998 Justification: Although this book contains very valuable information regarding our solar system and its formation, it is not as appropriate for a college faculty member as the two chosen selections because it provides relatively fundamental information that a college faculty member is likely to already know. If a friend of mine were to undertake a similar assignment to the one completed above I would offer the following advice. First, determine which areas are appropriate for background information and which are appropriate for further reading. For background information, look at the themes that are central to the chosen article and find sources that further explain those. Sources for further reading should include information that may build upon the contents of the initial article, or include information related to the article, such as recent discoveries. Once the topics for background and further reading have been decided upon it is easy to find sources using the university’s library catalog and online journal databases. Understanding which sources are appropriate for a given audience is based mostly on common sense. Sources from scholarly journals such as Icarus and The Astrophysical Journal are probably not appropriate for high school students or even entry level college students because of their advanced nature, but are suitable for college faculty members. Similarly, books found in the university library on the foundations of a subject or relatively basic articles from scientific magazines, such as Astronomy and Discover, are appropriate for high school and entry level college students, but not for college faculty members because of their broad, basic nature.
