A bit off topic, but interesting nonetheless. Uranium discovered in a Dutch scrapyard was originally from Heisenberg’s Nazi-era lab. Read on to learn a little more about the Nazi nuclear experiments, as well as Heisenberg’s role.
The cube, according to specialists at the JRC’s Institute for Transuranium Elements (ITU), was produced in 1943 for the Nazi nuclear programme and was used in the lab of famous boffin Werner Heisenberg (of uncertainty principle fame). The plate was apparently part of experiments by Heisenberg’s collaborator Karl Wirtz.
