I spent yesterday at the University of Colorado in Boulder at the physics department and JILA, which is a joint institute of the university and nearby NIST — a US government institute that focusses on standards and technology. Unlike my recent visit to NIST, which looked at some of the incredible challenges that have been overcome in order to turn cutting-edge technology into practical devices, yesterday was very much about big ideas in physics.
I spoke with black-hole expert Mitch Begelman about the significance of this week’s unveiling of the first-ever image of a black hole and you can hear that conversation in an upcoming episode of the Physics World Weekly podcast. Begelman also told me about his research doing computer simulations of the magnetic plasmas that surround black holes. These are done on one of the world’s most powerful supercomputers and are providing insight into the extremely violent environment that surrounds black holes and creates the radiation that we detect with our telescopes.
Neutrino detectors: Eric Zimmerman and Alysia Marino.
In a warm up to the April Meeting of the American Physical Society, which starts today in Denver and covers particle physics, I spoke to Alysia Marino and Eric ...
