Robots: Taking the Biscuit

Understanding Rape

Rape is one of the world's most serious and fast-growing crimes. A recent London survey found that one in six women had been raped at least once. In America it's one in four: that's one rape every 17 minutes. Tonight's Q.E.D. presents film of an experiment carried out at an American psychiatric hospital near Seattle. Four women victims were brought face to face with four convicted rapists. Psychiatrists at the Western State Hospital believe that rape is learned behaviour, which can be changed. They saw this face-to-face confrontation as one possible way of doing this. Q.E.D. took the film to Grendon Psychiatric Prison in Buckinghamshire to find out whether such an experiment could be of any value here ...

The Man Who Walks on Fire

Hugh Bromiley , a master firewalker and British martial artist, claims anyone can learn to walk on fire. Q.E.D, accompanied by a team of prominent scientists, observed the mass firewalk. Could the whole dramatic event simply be a dangerous delusion? Or does everybody possess untapped powers of mind over matter

Some doctors thought he might never even walk. Now he runs a mile every day and over the past year, 7-year-old Doran Scotson has been aiming for a time of 11 minutes.
