The Two Thousand Year Old Computer - BBC4, 9pm
Did computers really exist 2,000 years ago? This documentary joins a team of mathematicians, historians and other experts trying to solve the puzzle and meet the eccentric British engineer who has built his own version of Archimedes' astrolabe and lunar calendar.
