Adam Hart-Davis gets on his bike for another six-part series searching for tales of scientific discovery. This week he reveals the heroes of Bath, Stroud, Dorset and the New Forest, from the inventor of concrete to a pioneer of static electricity. He also demonstrates a way to measure the speed of a bullet.

Adam Hart-Davis's cycling tour of Britain takes him to Scotland, where he visits St Andrews to see how backspin helps a golf ball defy gravity and Stonehaven, home of the inventor of pneumatic tyres. Plus he builds his own radar, and uncovers the origins of fibre optics in Edinburgh.

Adam Hart-Davis visits London as he salutes more pioneers of science. He sees how Brunei tunnelled under the Thames, discovers the inventor of the vacuum cleaner, and follows the trail of a cholera outbreak in Soho. Plus the rector who found how sap gets up trees, and the revolutionary motor that worked without revolving.

Adam Hart-Davis celebrates more pioneers of science, this week in Yorkshire and Lancashire, where he uncovers the steelmaking process that put Sheffield on the map, re-creates the first pollen count, and discovers a working 19th-century aeroplane.

In the last programme of the series, Adam Hart-Davis celebrates the 200th anniversary of the Royal Institution - made famous by pioneering scientists Michael Faraday and Humphry Davy.

Hart-Davis makes an electric motor from a meat-pie tin and shows how it was proven that when horses gallop there is a point when all four feet are airborne. A new series is planned.
