A new portrait the great enlightenment scientist Robert Hooke is to be hung at the Institute of Physics in London, a recreated likeness after his only portrait was destroyed in a fire, some say at the hands of his rival Isaac Newton.

Rita Greer, painter of the Hooke portrait, and Dr Allan Chapman, historian of science at Oxford University and Hooke biographer, discuss the new painting and the life of one of the UK's great scientists.
