...proposed, and rig up a Rube Goldberg contraption involving a hammer, a vial of poison and a quantum triggering device. If an electron is in one position, the hammer will remain safely cocked. But if the electron moves into the opposite location, the hammer will drop, smashing the vial and killing...
...Booble,” not to mention various indexes with payloads worth of textbook information on semiconductors. And of course, every page of equations has—you guessed it—random pictures of Britney at her best. Sometimes, her figure is even used to demonstrate paths of electron movement...
Today most forensics labs that conduct the test rely instead on scanning electron microscopes. Just touch a bit of tape to a suspect's hands, place it under the scope and hit it with a stream of electrons. The elements in gunpowder give off distinct X-ray signatures, and if they are there, the electron beam will spot them. The drawback? "You don't get to see the terror on people's faces when you pour hot paraffin on their hands," says Fischer. "I think it encouraged some people to confess...
...physics, the exclusion principle holds that an electron within an atom, once in orbit, excludes any other particle from occupying exactly the same orbit. That may be as apt a metaphor as any for the unique odyssey of the collection of atoms that was Andrei Sakharov. The life of the dissident Russian physicist - acclaimed as both the creator of the Soviet H-bomb and the conscience of his country - spanned the years from Lenin to Gorbachev, the rise and fall of Soviet communism and the triumph of physics. Who but Sakharov could so personify such an age? Now, more than...
