Peter Hoffman is a physicist and materials scientist, and he brings those perspectives and sensibilities to the description of how life converts chemical energy into order and motion. The "Ratchet" in the title is Feynman's Ratchet, a gedanken experiment described in Feynman's "Lectures on Physics" and reminiscent of Maxwell's Demon.

Samuel Arbesman, a mathematician and network scientist, uses the idea a half-life as an analogy for the changes in human knowledge that science brings. He discusses both the changing rate at which new science is done and the speed at which old results are replaced by newer ones. The analogy is far from perfect, but it emphasizes some critically important aspects of the processes of science.
The respected education reformer Diane Ravitch, previously one of the major architects and proponents of No Child Left Behind, has not only taken a new tack, but reversed course. With her 2011 book, she became a leading voice critical of the Obama-Duncan version, Race to the Top. This essay by David Denby describes her evolution.
New York Times blogger Nate Silver demonstrates how probability and statistical thinking can be used to analyze practical problems in our society. A lively, practical, and informative book!
This is a lively collection of essays about some of the great (mostly English, but not entirely so) chemists of the nineteenth and twentieth centuries. It brings to life many great names of our science.
Alexandra W. Logue, executive vice chancellor and provost of the City University of New York, reminds us that the ideas and tools we are finally getting around to using have been around for a while.
Professor Joe Schwarcz of McGill University is Canada's foremost public spokesperson for science. His columns in the Montreal Gazette and in Canadian Chemical News and his radio program on CJAD in Montreal reach thousands of readers and listeners, and have provided grist for his many popular books about science and especially chemistry.
In an attempt to get at least a little discussion of science policy into the Obama-McCain campaign of 2008, Richard Muller wrote "Physics for Future Presidents" and offered a popular course at UC Berkeley with the same title. While nearly all of the issues he raised were ignored by the campaigns and during the subsequent four years, he has returned with a book focused just on energy science and related issues.
