This Day in Science History - March 21 - Jean Baptiste Fourier

March 21th is Jean Baptiste Fourier's birthday. Fourier was a French mathematical physicist who is best known for a method to express a periodic function into a sum of simple sine and cosine expressions. This process is used extensively in optics, quantum mechanics, acoustics and electrical engineering.

He was also the first to describe what has become known as the "greenhouse effect". He described a theory where the atmosphere served to heat the surface of a planet by slowing heat loss.
