Kathy Loves Physics & History | How the X-ray Machine Works & Was Invented: from Hertz to Lenard @Kathy_Loves_Physics | Uploaded 6 years ago | Updated 11 hours ago
The x-ray machine predates the discovery of the x-ray by at least 26 years! This video is on *why* Heinrich Hertz led Phillip Lenard to create an x-ray machine that was perfectly suited to discover the x-ray and how it worked.
The music is by the fabulous Kim Nalley (and the theme song is her rendition of "Electricity, Electricity" from Schoolhouse Rocks)
The video of an actor portraying Roentgen is from "100 Greatest Discoveries in Medicine" with the fabulous Bill Nye:

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.
