The Sky is Falling

How likely is it that an asteroid or a comet of significant size will impact the earth, and what would be the consequences? It is now widely accepted that the dinosaurs were wiped out by such an event, and recent research suggests that previous estimates of the number of asteroid impacts may have been much too low.

The Ten Most Beautiful Experiments

Lists of "the best" movies, books, sports stars, American Idols, etc. etc. are often intriguing and controversial. Science has its own lists, be they Nobelists or most-cited publications.

Gusher of Lies: The Dangerous Delusions of 'Energy Independence'

Robert Bryce is a respected commentator on the energy industry. He writes for Atlantic Monthly, the Guardian and The Nation, and he has written books about Enron and about the oil industry in Texas. In "Gusher of Lies", he confronts politicians and entrepeneurs who claim that the United States should/could become "energy independent" at any time in the forseeable future.

"A Special Brew", by Christopher Mundy, Shawn Kathmann, and Gregory Schenter is the one that is most "chemical", but the others describe some environmental aspects of water resources.
