Where did the first law of thermodynamics come from? Why is energy called energy and what has that to do with heat? Where did the 1/2 in kinetic energy come from? Watch this video to find out the real people behind the science!

How did Joseph Fraunhofer, a poor glassmaker, get saved from poverty by a prince and then discover spectroscopy (Fraunhofer lines), single slit diffraction AND the diffraction grating? I use primary sources to discover the background and the physics of this epoch making discovery.
