Physics lost one of its unsung heroes this week with the passing of Kenneth Wilson (1936-2013). What’s that? You’ve never heard of him? You’re not alone. He was never one to seek the spotlight. But his influence was profound. Wilson was a quantum field theory visionary, master of renormalization, and an inspiring physics hero. Over at the Quantum Frontiers blog, John Preskill declared: “We are all Wilsonians now,” and mused on how Ken Wilson changed how we think about physics. Meanwhile, Sean Carroll (a.k.a. the Time Lord) opted for a few thousand words on effective quantum field theory, renormalization, and something called “Fock space” in honor of Wilson’s passing.
Fermi Problem: X-Ray Assassins. A KKK member and his accomplice were arrested for a plot to build a portable x-ray machine that they hoped to use to murder Muslims. The master plan? To “expose their victims to doses of radiation that would lead to their death in a matter of days.” There’s just one problem, as Physics Buzz pointed out: “To expose a person to 800 joules of x-rays would require about 4,000,000 joules.”
