John Tyndall was born in 1820 in Co. Carlow, Ireland. He was one of the most famous experimental physicists of his day and he was also one heck of a mountaineer. As well as being proclaimed the father of meteorology and climate change, he also had a number of first ascents, i.e. he was the first person to reach the peak of a number of unclimbed mountains.
Despite his achievements, he has been largely forgotten by the general public.
In this podcast we step back in time to a lecture theatre in London in the mid-1800s where Tyndall is about to astound his audience with something akin to magic.
