C2ST Speakeasy at Geek Bar's SCIENCE! Tuesday
"Vandals of the Void: Damaging Meteors from Chelyabinsk to Chicago" with William S. Higgins
Two years ago, a window-shattering shock wave injured 1400 Russians, and startled the world, as a small asteroid hit Chelyabinsk. Violent meteors are rare, but they can be devastating—and meteors have assaulted Chicagoland at least twice. Join William S. Higgins for a look at the science behind the Chelyabinsk blast. And hear the story of Chicago's local impacts: one smaller than Chelyabinsk, one MUCH bigger.
William S. Higgins, a volunteer speaker in NASA's Solar System Ambassador program, speaks and writes about spaceflight, astronomy, and other topics in science and technology. He works as a radiation safety physicist at Fermi National Accelerator Laboratory, where he is involved in the transport of high-energy particle beams. He plays baritone ukulele, if not skillfully, then with enthusiasm. Long active in Chicago's science fiction fandom, he researches the history of SF, and often contributes science to SF convention programs. In the past he wrote a monthly science column for the Lerner newspaper chain; recently, he has become an editor for the Vatican Observatory Foundation's member forum.
