I went to the top of Ben Nevis in the holidays. At the top there is a ruined weather station with this plaque honouring a Nobel Prize for physics.
It was awarded to CTR Wilson for his invention of the cloud chamber, a device for allowing you to see the invisible paths of radioactivity by getting vapour trails to condense where they have created ionised air molecules along the way. He was inspired to do this by his observations of clouds from the top of Ben Nevis.
