...says??there's??no??such??thing??as??a??eureka??moment? Physicist David Grier sure had one. Grier and graduate student Eric Dufresne were trying to build a new kind of "optical trap"--a device that splits a laser beam and uses it to capture particles of a single substance. They knew that multiple traps, used in tandem, could let scientists play traffic cops on a molecular level, separating a substance into component parts--removing bacteria from blood, for example. For a year, Grier and Dufresne had been trying out fancy glass splitters, but nothing had done the trick...
...self-described friend of Franklin noted on a weblog Wednesday, the Harvard particle physicist is not quite a lexicographic trailblazer. In October 2003, after Limbaugh—formerly an ESPN commentator—drew fire for racially insensitive remarks about Philadelphia Eagles quarterback Donovan McNabb, a Limbaugh fan on a conservative website wrote: “even if Rush was just wrong in what he said, why does this rise to a resignable gaff...
...Right before he mentioned my research he talked about a physicist that stopped light or something,” she said. “I thought to myself ‘This is totally out of proportion...
...cold Chicago day in the late 1990s, physicist David Grier was fiddling around in his laboratory with a cheap piece of plastic and a laser. Grier and a graduate student named Eric Dufresne were trying to build a new kind of "optical trap" - a device that splits a laser beam and uses it to capture particles of a single substance. Multiple traps, used in tandem, could let the scientists play traffic cop on a molecular level, separating a substance into component parts - removing bacteria from blood, for example. But first they had to make it work. For a year, Grier...
...explanation of last resort. When he first began looking at it back in the late 1980s, particle theorist Steven Weinberg of the University of Texas hoped the anthropic principle might go away. But the opposite happened. "It's not something that we're particularly happy about," he says. Every physicist dreams of being able to calculate everything from a set of fundamental laws. But at the same time, Weinberg says, "it's important to be realistic. We may just have to get used to the fact that some of the things we call fundamental constants may be historical accidents...
