ABSTRACT

Similar stories of ‘Eureka moments’ are dotted through the literature of science. One Sunday afternoon, in the spring of 1765, James Watt went walking on the green in Glasgow, worrying about the loss of heat in the Newcomen steam engine. As he walked, the idea of the separate condenser came to him, an idea that was to transform steam power and kick-start the industrial revolution. ‘I had not walked further than the Golfhouse when the whole thing was arranged in my mind.’
