Revelations & Revolutions

From radio waves bigger than a house, to gamma rays smaller than the nucleus of an atom, the electromagnetic spectrum is buzzing around us – but until recently we have only been aware of the tiny visual part of the spectrum. Jim shows in this episode that the discovery of radio, X-rays, microwaves and a whole host of other phenomena, lay at the heart of what drove and some of the great names of modern physics - Curie, Faraday, Planck and Einstein. We’ll also use hi-tech cameras to reveal the hidden world outside the visible spectrum.
