Wilson's experiments
In
September 1894 the Cavendish physicist C.T.R. Wilson
spent a few weeks as a meteorological observer investigating
the weather at the top of Ben Nevis. He was impressed
by the effects of sunlight on the clouds around the
mountain, and decided to try to reproduce them in a
laboratory.
