In Minneapolis on Friday, June 21, 1957, I went to General Mills for a job interview for lab technician in their Radiation Physics Laboratory. They hired me a month later. At that time, I wanted to be a physicist when I grew up, so it seemed like a fit to me. Above: a cobalt-60 facility similar to the one I worked with, showing the eerie blue Cherenkov radiation of charged particles interacting with water molecules.
