Join Freethinker Podcast host Edouard Tahmizian in this one-and-a-quarter hour interview with Rational Science podcaster Bill Gaede and Cypress College philosophy professor Jason Thibodeau as they explore what physical meaning, if any, can be derived from idealized mathematical physics. Gaede first outlines the difference between qualitative physics, whose three spatial dimensions (e.g., length, width, and height) are underwritten by genuine physical concepts like directions at 90° degree angles to each other, and mathematical physics, whose dimensions are underwritten purely by numerical magnitudes like the number of points necessary to locate an object within a coordinate system (e.g., latitude, longitude, and altitude). While genuine physics deals with perpendicularly defined dimensions (direction and orthogonality), mathematical physics only deals with number lines (with magnitudes) defined in relation to some locational reference point. The discussion then turns to whether it's possible for there to be additional spatial dimensions to the length, width, and height dimensions that we're all familiar with, what exists inside a black hole, whether the universe started with a Big Bang, how we should understand the nature of light and the nature of time, and much more! Check out this fascinating discussion about conceptual misunderstandings within even a hard science like physics!

Join Freethinker Podcast host Edouard Tahmizian in this 40-minute interview with Rational Science podcaster Bill Gaede about what Albert Einstein's train paradox reveals (or doesn't reveal) about the nature of time and the measurement of it, how the standard physical concept of spacetime (e.g., in concepts like simultaneity, time dilation, time travel, and warping spacetime) reifies time, and how the mathematization of physics is divorced from physical reality. In the final three-quarters of the interview, Gaede turns to how his counterintelligence work against Cuba created a spy-versus-spy dynamic that the Cuban government unsuccessfully tried to exploit. Tune-in for any always-fascinating interview with a contender for the most interesting man in the world (with or without the Dos Equis)!
Join Freethinker Podcast host Edouard Tahmizian in this 45-minute interview with Rational Science podcaster Bill Gaede about the conceivability of 4-dimensional spatial cubes—hypercubes or tesseracts—and his fascinating former life as a Cuban spy. After noting his intellectual "falling out" with Carl Sagan over his atheism, his reliance on mathematical physics and the modern conception of the scientific method, and his Polyannish vision of humanity's future, Gaede explains how the mathematical concept of dimensions differs from the physicist's concept of them. Sagan, for example, conceptualizes a 2-D square as a shadow of a 3-D cube, and goes on to conceptualize a tesseract as the 3-D shadow of a 4-D hypercube. But is such a hypothetical entity physically conceivable? If time is conceived of as the fourth dimension that connects the perpendicular lines in our visual representations of a tesseract, then the tesseract actually involves nested times (when rotated or moving), such that you really have two dimensions of time added (for 5 dimensions, not 4), rendering it conceptually impossible. In the second half of the interview, Gaede talks about his life in Argentina before he worked as a manager for Advanced Micro Devices (AMD) in California, passing trade secrets on to the Cuban government from the mid-1960s until 1979, before turning himself in to the CIA in 1992 and then doing counterintelligence as a double agent for the FBI at Intel, passing on disinformation back to the Cubans thereafter. Gaede recounts the fascinating story of how AMD's discovery of his betrayal ultimately led to his cover being blown. Check out this fascinating dive into the conceivability of purely mathematical concepts that dovetails into the perils of life as an industrial spy!
Join Freethinker Podcast host Edouard Tahmizian in this shy of half-hour interview with Bill Gaede, cohost of the Rational Science podcast, where they explore an understanding of mathematical physics alternative to physical interpretations of quantum mechanics (on phenomena like action at a distance) and general relativity (on phenomena like gravity) that Gaede calls the rope hypothesis, in which "shape" is a primary physical property. Tune in for Gaede's explanation of how magnets attract and a short history of his previous life as an industrial spy during the Cold War.
