Horizon - 1964-1965: Strangeness Minus Three
First transmitted in 1964, the prediction and recent discovery of a fleeting particle may transform our ideas about the ultimate structure of matter.
First transmitted in 1964, it took physicists at Brookhaven, Long Island, New York, two years and 97,025 photographs before they successfully identified a predicted new particle, which has a unique characteristic known as 'strangeness minus three'. Contributing physicists include Murray Gell-Mann, Yuval Ne’eman and Richard Feynman.
