A moon-walker is suffering from visions. His proposed human-centered space exploration scheme would divert resources to adventure from science.
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.
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.
The fact that spacecrafts Pioneer 10 and 11 are not moving quite as fast as they were predicted to, has led to speculation that there might be something wrong with general relativity. Einstein may be dead, but his concepts still reign.
I enjoyed so much Dava Sobel's previous books, "Longitude" and "Galileo's Daughter" (both of which were Hal's Picks), that I was eager to read her latest, which was judged "best science book" for Fall, 2011 by Publisher's Weekly.
Paul Hewitt may be the best-known physics teacher in the US. Not only has he written outstanding books for the teaching of physics and physical science, he is also the author of the very popular monthly "Figuring Physics" column of The Physics Teacher.
Owen Gingerich is the author of one of my favorite books, "The Book Nobody Read", which was my Pick for October 2004 (could it have been that long ago?), which combines astronomy, history research, and bibliophilia.
Do tsunamis affect global warming? Well, the 2004 Indian Ocean catastrophe probably indirectly decreased the amount of carbon dioxide going into the atmosphere by destroying the lives of 200,000 victims and the livelihoods of probably 250,000 more. Of course, it also negatively affected coral reefs, mangroves and other wetlands, forests, and plant diversity.
