Melvyn Bragg and his guests discuss the ancient Greek astronomer and mathematician Ptolemy, and consider how and why his geocentric theory of the universe held sway for so many centuries. In his seminal astronomical work, the Almagest, written in the 2nd century AD, Ptolemy proposed that the Earth was at the centre of the universe and explained all the observed motions of the Sun, Moon, planets and stars with a system of uniform circular motions which he referred to as 'epicycles'. But Ptolemy w...

But the divide between these two schools of thought...
