Book Review: Science Under Siege: Defending Science, Exposing Pseudoscience edited by Kendrick Frazier
Scientific literacy has taken a hit. Facts are absent or distorted by spin doctors, leaving people to flounder when interpreting complex issues, writers argue in this new collection of essays.

Book Review: Spycraft: The Secret History of the CIA’s Spytechs, from Communism to Al-Qaeda by Robert Wallace and H. Keith Melton with Henry Robert Schlesinger
Most spy stories star a James Bond–like figure, but the tales of espionage in Spycraft feature behind-the-scenes technologists more akin to Q, Bond’s gadget guru. The authors describe how CIA scientists and engineers developed technologies that have shaped U.S. intelligence since the late 1950s. Drawing from interviews with spies and gadget engineers, the story moves […]

The Status Quark
When in the course of scientific events it becomes necessary to dissolve allegiances to established beliefs, you can expect to face a lot of flak. New scientific ideas, the German physicist Max Planck once observed, triumph not because of the power of reason, but because their opponents eventually die. It was perhaps a slight exaggeration. […]

Letters
Philosophers strike back As someone who has taught philosophy of science and history of science for 30 years, I must take exception with Tom Siegfried’s editorial, “Philosophers don’t know what scientists can’t do” (SN: 7/18/09, p. 2). Of course, they don’t! But neither do scientists! Immanuel Kant and Auguste Comte were just as wrong about […]
