University of the 3rd Age - NOT amateur radio

For about 14 years, I have been attending U3A courses. It is great fun learning new things just for fun. Some involve going into Cambridge and some are on Zoom. The Zoom talks are very effective, and far better than I ever expected.

This year I am studying Medieval History and quantum mechanics, the latter was last done in the late 1960s at university! It is hard!!

Quantum mechanics is spooky. One has to forget what we perceive as reality and accept that sometimes things can be quite different. One aspect is wave functions that seem to imply things exist in all space and all time, past and future included. Things are most probable now, but entangled things even at the extremes of the universe, know about each other instantaneously. Forget the speed of light - instantaneously means just that! Some of these things have been proven by experiments.
