Lawrence Krauss, a professor of physics and astronomy at Case Western Reserve University, has a reputation for shooting down pseudoscience. He opposed the teaching of intelligent design on The NewsHour With Jim Lehrer. He penned an essay for the New York Times that dissed President Bush’s proposal for a manned Mars mission. Yet in his latest book, Hiding in the Mirror, Krauss turns on his own—by taking on string theory, the leading edge of theoretical physics. Krauss is probably right that string theory is a threat to science, but his book proves he’s too late to stop it.
String theory, which stretches back to the late 1960s, has become in the last 20 years the field of choice for up-and-coming physics researchers. Many of them hope it will deliver a “Theory of Everything”—the key to a few elegant equations that explain the workings of the entire universe, from quarks to galaxies.
