CTR Wilson in the Pentland Hills

I was very pleased to come across this memorial to CTR Wilson at the foot of the Pentland Hills near Edinburgh. He won the Nobel Prize for Physics for his invention of the cloud chamber. This blog started after a trip to Ben Nevis and it was his time as an assistant at the observatory on the top of Ben Nevis that inspired him to invent the cloud chamber. This invention was one of the earliest particle detectors and thus on the direct line of development that led to CERN. I've posted about cloud chambers before when we have had dry ice in. I found this wonderful set of anecdotes about his life https://www.rse.org.uk/cms/files/events/reports/2012-2013/CTRWilson_Conference.pdf which has a piece from someone I assume to be THE Tam Dalyell, the famous Labour MP, whose interest in science seems to have stemmed from a chance meeting with CTR Wilson.
