The cloud chamber has played a massive role in particle physics. Saturated alcohol vapour in a container allows us to display the path of a particle, such as a muon, as it passes through the chamber. The video below shows the kind of trails that a cloud chamber will produce.
I’m posting about the cloud chamber after reading an article in Scotland on Sunday about its inventor, CTR Wilson – winner of the 1927 Nobel Prize for Physics. I didn’t know Wilson was Scottish and I didn’t know that his research was inspired by the cloud observations he performed while posted to the Highlands, Ben Nevis to be precise.
