BBC Radio 4 - Schrodinger's Quantum Kittens


Robin Ince examines Schrodinger's Cat, the paradox at the heart of quantum physics, and discovers its influence on science and popular culture. Fifty years after the death of Nobel laureate Erwin Schrodinger, the quantum mysteries of his cat-in-a-box paradox still continue to drive physicists in research today. Can a living thing be both alive and dead at the same time?

Schrodinger's experiment was an almost playful creation, but one that stabbed at the heart of the 1930s physics establishment. By the 1950s, US physicist Hugh Everett concluded that, indeed, both a dead cat and an alive cat can exist, but in separate universes. His 'Many Worlds' theory inspired authors, from Philip K Dick to Philip Pullman.

Robin follows in the Austrian physicist's footsteps to Oxford University, where Schrodinger was once a fellow, and unearths some original archive at Magdalen College. Physicist Sir Roger Penrose speaks about its impact on quantum theory to this day. Why has Schrodinger's Cat gained such currency not just in science but popular culture? Writer Alan Moore tells how it created a new wave of 1960s sci-fi literature.

So why has Schrodinger's Cat caught the imagination of non-scientists? How is it misinterpreted and used to explain mankind's many unknowns? What is its place at the cutting edge of quantum physics? Robin meets today's physicists and thinkers who still tangle with the idea. And we find, no doubt, that Schrodinger's Cat (in all probability) is very much alive today.

BBC Radio 4 - Science vs The Stradivarius

 
Can modern technology identify the elusive components that give Stradivarius violins a unique voice? Analysts have submitted the master instruments to a battery of tests, from CT scans to burning original samples of varnish, but are they just chasing a myth? Professor Trevor Cox investigates

BBC Radio 4 - The Feynman Variations

 Size: 53.59 MB
Richard Feynman (1918-88) was one of the most remarkable and gifted theoretical physicists of any generation. He was also known as the 'Great Explainer' because of his passion for helping non-scientists to imagine something of the beauty and order of the universe as he saw it. 

A tribute to Richard Feynman, brilliant physicist, and all round smart guy. Includes most of the key stuff, and some new material from people who knew him.
