Ep 208: David Deutsch’s ”The Fabric of Reality” Chapter 11 ”Time: The First Quantum Concept” Part 3
Physicist and author David Deutsch explores the concept of time as a quantum concept within the multiverse. Topics include deterministic laws leading to subjective unpredictability, free will implications, identity in the multiverse, quantum probability, and the complexities of time and potential time travel. The discussion challenges traditional notions of time flow and causation, setting the stage for a deeper understanding of a multi-dimensional reality.

Ep 207: Variations on a Conjecture
Dive into the intricate relationship between creativity and the universe's evolution from the Big Bang to biological diversity. Explore how conjecture drives knowledge and societal progress, emphasizing the fluid nature of understanding. Discover the stark contrasts between biological evolution and human cognition, as well as Karl Popper's insights on knowledge creation. Finally, grapple with the unpredictability of the future and the limits of our foresight, advocating for active engagement in the present.

Ep 206: Sam Kuypers (Time: The First Quantum Concept Part 3 - and more).
Theoretical physicist Sam Kuypers discusses the evolution of our ideas about time from Newton to quantum theory, exploring the clash of General Relativity and Quantum Theory, the significance of non-commutability, and the static nature of time through quantum concepts. The podcast also delves into the differences between Heisenberg and Schrödinger pictures in quantum theory and the resurgence of interest in physics.

Ep 203: David Deutsch’s ”The Fabric of Reality” Chapter 10 ”The Nature of Mathematics” Part 4
Discussion on the fallibility of mathematics and the relationship between physics and mathematics. Exploring the nature of mathematics, including the irrationality of the square root of two and the abstract concept of 1. Shifting perspective from seeking ultimate truth to creating explanatory knowledge. The limitations of human knowledge and the importance of seeking knowledge over certainty. The inadequacy of traditional mathematical methods and the limitations of the Turing machine. Exploration of absolute necessary truth in mathematics and the role of proof in establishing mathematical propositions.
