RedEaredSlider writes "In science fiction, explorers wave around a single device and pick up many kinds of radiation — think of the tricorders on Star Trek or Dr. Who's sonic screwdriver. A professor at Oregon State University is bringing that a bit closer to reality, though in this case it's for finding radioactive material. It's a radiation spectrometer, and it works on a very old principle: particles and photons that hit certain materials will make them emit flashes of light. But for decades, radiation spectrometers had been limited to detecting only one kind of radiation at a time. David Hamby, an OSU professor of health physics, felt that there was a need for a device that could see at least two kinds of radiation, as well as be smaller than the models currently available."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
