Lost Model of Electrodynamics - Dr. André Koch Torres Assis, DSPod 204

Описание: Get your DEMYSTICON 2024 tickets here: https://www.eventbrite.com/e/demystic...

Dr. André Koch Torres Assis is a professor of physics at the University of Campinas in Brazil. He has worked on myriad topics including gravitation (Relational Mechanics, Mach's principle and the origin of inertia, absorption of gravity), electromagnetism (Weber's Electrodynamics, Ampère's force between current elements, electric field outside resistive wires carrying steady currents, propagation of electromagnetic signals), cosmology (Hubble's law of redshifts, cosmic background radiation, tired light, infinite universe in space and time) and history of science. Our conversation explores how physics, in the main, seems only to be able to tolerate one theoretical framework at a time. This has the potential to leave many revelations behind on the cutting room floor. We explore the consequences of this dynamic across the past few hundred years.

PODCAST INFO: Anastasia completed her PhD studying bioelectricity at Columbia University. When not talking to brilliant people or making movies, she spends her time painting, reading, and guiding backcountry excursions. Shilo also did his PhD at Columbia studying the elastic properties of molecular water. When he's not in the film studio, he's exploring sound in music. They are both freelance professors at various universities.
