How to Dunk a Doughnut

Hay Festival 2003, 
Count Rumford discovered the principle of heat convection after buring his mouth on hot apple pie. Fisher attracted worldwide attention with his experiments on the physics of biscuit dunking and with the freezing speeds of hot and cold water. He examines how scientists exploring the most commonplace and mundane phenomena have provided insight into some of the most profound scientific questions and uncovered some of nature's deepest laws.
