Although initial results were encouraging, physicists searching for an exotic five-quark particle now think it probably doesn't exist. The debate over the pentaquark search shows how science moves forward.
Stanford Linear Accelerator Center librarian Lesley Wolf needed a creative idea for the next library display. Ten-year-old Connor Reed had lots of free time this summer and an extensive set of K'nex, the flexible equivalent of Lego.
In creating neutrinos for the MINOS experiment at Fermilab, the NuMI focusing horn delivers batches of protons using intense magnetic fields generated by 200,000-ampere pulses of electric current.
Pick a number: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113 and so on and on and on and on . Get the picture?
With his genius and his unmistakable appearance, Albert Einstein is an icon of both science and culture. Since his passing Einstein has inspired films, books, and even an opera, Einstein on the Beach. Not surprisingly, his popularity pays off handsomely.
"Since middle school, I've always had plans to get rich," says Michael Binger, a theoretical particle physicist at Stanford Linear Accelerator Center. On August 11, 2006 his dream came true: Binger placed third at the World Series of Poker Championships in Las Vegas.
