Collider: The Search for the World's Smallest Particles

Paul Halpern. John Wiley & Sons, $27.95 (260pp) ISBN 978-0-470-28620-3

Halpern (What's Science Ever Done For Us?), professor of physics and mathematics, makes particle physics accessible in this look at the Large Hadron Collider (LHC) ""and the extraordinary discoveries likely to be made there."" Beginning with the philosophers and scientists who shaped our understanding of the universe over centuries, Halpern explains complex topics and theories concisely, frequently drawing on deft analogies: the ""fleeting nature of neutrinos is akin to a featherweight, constantly traveling politician... neutrinos never hang around long enough to make enough of an impact to serve as uniters."" After tracing a path from Boyle and Newton through Mendeleev, Maxwell, Rutherford and Einstein, Halpern discusses modern discoveries and details the equipment utilized, from cloud chambers to various kinds of particle accelerators. The bulk of the text focuses on particle physics studies from the past four decades, in the U.S. at Fermilab and the costly but uncompleted Superconducting Super Collider, and in Europe at CERN in Switzerland (responsible for the LHC). Halpern makes the search for mysterious particles pertinent and exciting by explaining clearly what we don't know about the universe, and offering a hopeful outlook for future research.
