For those celebrating Thanksgiving this week, I wish you all a happy and safe celebration.
Of course, as several physicists grumbled on Twitter this morning, “defied physics” is a silly way to describe these plays. These aren’t happening in defiance of physics, they’re happening because of physics. Physics is absolute and universal, and never defied– the challenge and the fun of these plays is to explain why and how these seemingly impossible shots are consistent with known physics.
Your body is a small-scale mine of radioactive particles. You receive an annual 40-millirem dose from the natural radioactivity originating inside of you. That’s the same amount of radiation you’d be exposed to from having four chest X-rays. Your radiation dose level can go up by one or two millirem for every eight hours you spend sleeping next to your similarly radioactive loved one.
“Leo was a prodigious scientist,” said his longtime UChicago colleague Sidney Nagel, the Stein-Freiler Distinguished Service Professor in Physics. “His work on statistical mechanics is one of the great achievements of 20th-century theoretical physics. It laid the conceptual and mathematical foundations for some of the most insightful and effective tools on which our modern understanding of nature is based.”
Kadanoff’s work has applications throughout physics, ranging from condensed matter (liquids and solids) to elementary particles, Nagel said, with the reach of his work extending to mathematics and other sciences.
