Temperature & Electromagnetic Radiation: Feynman's Perspective

[jaydnul]

Since temperature is no more than vibrating atoms (in Feynman's words), wouldn't that induce a changing electric field, just very slow in some cases? If so, is everything that is not 0 degrees kelvin radiating some kind of EM radiation? Like an ice cube, does it radiate small amounts of radio waves? I this why the human body radiates infrared?

Yes this is all correct except for the radio waves. Read about Black body radiation http://en.wikipedia.org/wiki/Black-body_radiation
