There was more stimulating discussion about the history of physics on BBC Radio 4 this morning.
Melvyn Bragg was joined by physicists Jim Al-Khalili and Frank Close, and historian Frank James for a lively chat about the history of electromagnetic radiation.
The team began with a discussion of Newton’s particle theory of light and moved swiftly on to the early 19th century and Thomas Young’s double slit experiment – which established the wave nature of light…
…but that’s when I bumped into a colleague who was also walking to work and stopped listening!
According to the BBC website – where you can listen to the discussion on line – the trio then traced the histroy of electromagnetic radiation through the work of Michael Faraday, Henri Becquerel, Max Planck, Ernest Rutherford and others.
