On this day in the history of chemistry, the first reports of nuclear fission were made in 1939. Fission is the breaking apart of big unstable elements such as certain isotopes of uranium or plutonium into multiple smaller elements.

Amazing that this was as late as 1939. I just read about "the demon core" the other day:

There are lots of horrifying stories of radioactivity-related accidents. Here are two particularly terrifying ones, each in their own way: The SL-1 Accident (https://en.wikipedia.org/wiki/SL-1#Accident_and_response) and the Cecil Kelley Criticality Accident (https://sgp.fas.org/othergov/doe/lanl/pubs/00326644.pdf).
