What we really feel when we feel "cold"

Temperature is just a measure of jigglyness, says Henry Reich of Minute Physics. Not in the "I don't think you're ready for this jelly" sense, but at the scale of atoms. And it's this jiggle that can help explain why two things that are, technically, the exact same temperature can feel totally different when we touch them. Great science for a cold day!
