I just learned how x-rays are produced. I learned some uses for x-rays. I learned from yahoo news that Farm jobs are one of the most hazardous least paid jobs. I learned that Dimitri Mendeleev discovered of periodicity by looking at a deck of cards. I learned that BaPt(CN)6 was a scintillation screen that was used to detect x-rays. It glows a green color. I know it's a lot of jargon/geeky stuff but that's what I'm into. But the question stands:
What did you learn today?
