Yep - nuclear physics at that time of day was indeed a bit of a surprise. Still, I got one up on the Chief Tech in the white coat who didn't know why electron orbital shells were termed 'S, P, D and F' - I did, thanks to a prehistoric chemistry master at school who was heavily in to spectroscopy.
Somehow I get the feeling that digi-yoof doesn't get to study such things these days. For doubtless 'twould "Do 'is 'ed in"!
I always wondered whether we would have been issued with those natty gold film visors shown in the atomic age movies - or whether the 'Jake the pirate' eye patches and the tatty old curtains in the bomber would have been our sole protection against nuclear flash.
