Now a group of prominent scientists and politicians who believe his achievements rank alongside those of Albert Einstein and Marie Curie are to launch a campaign to have issued a commemorative banknote to honour long-forgotten inventor CTR Wilson. Wilson was awarded the world's most prestigious science prize in 1927 for his invention of the cloud chamber, inspired by the optical effects he saw in the sky in the Highlands. His invention was pivotal in the development of particle physics and has been described as "the most original and wonderful instrument in scientific history".
The cloud chamber, of course, was one of the earliest particle detector that was used, and featured prominently in the early high energy physics experiments. I still use a cloud chamber whenever we have visitors, and it is amazing how many have never see such a thing. People continually are amazed when they see all of these tracks zipping around in the chamber. It reinforced the idea that we are surrounded by cosmic/terrestrial "radiation", and something this visual tends to stick in people's head faster and easier than simply telling them, or showing them on posters.
