Mistaking the Map for the Territory in Physics - Dr. Jacob Barandes, Harvard, DemystifySci #344

Dr. Jacob Barandes is a professor of Physics at Harvard University who studies the foundations of physics. He has emerged as a leading skeptic of the idea that our universe is somehow fundamentally mathematical in nature, marking a full cycle of more than two thousand years of ink spilled about the nature of the universe. Barandes has found that there is a way of modeling the basement membrane of reality as being made of bodies with location, where everything from superposition to electricity and magnetism are a product of the motions of these bodies. Our conversation spans the basic principles that Barandes has used to arrive at this conclusion, the vital role that confusion over what constitutes a “measurement” plays in producing a highly paradoxical interpretation of nature, and the fact that this debate about the nature of the universe - substance versus mathematics - has been raging for more than two thousand years, with no end in sight.

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.
