The Large Hadron Collider is famous for its size (17 miles in circumference), its cost (more than 7 billion euros), and accomplishments (the discovery of the Higgs boson chief among them).
SLAC's two-mile-long linear accelerator could be considered the LHC of its day -- 50 years ago.
In this video, recorded during the Aug. 24, 2012, symposium commemorating those 50 years, Frank Zimmerman of CERN gives a crash course on the history of particle colliders, from the first cyclotron, built by Ernest Lawrence and his graduate student Stanley Livingston in 1931 (that could fit in the palm of a hand), to CERN's nation-spanning behemoth. He also lets the audience in on his own secret master plan for ever more powerful accelerators -- not just at CERN, but at SLAC.
