Description

Quantum mechanics is our best theory of how reality works at a fundamental level, yet physicists still can’t agree on what the theory actually says. At the heart of the puzzle is the “measurement problem”: what actually happens when we observe a quantum system, and why do we apparently need separate rules when it happens? David Albert is one of the leading figures in the foundations of quantum mechanics today, and we discuss the measurement problem and why it’s so puzzling. Then we dive into the Many-Worlds version of quantum mechanics, which is my favorite (as I explain in my forthcoming book Something Deeply Hidden). It is not David’s favorite, so he presents the case as to why you should be skeptical of Many-Worlds. (The philosophically respectable case, that is, not a vague unease at all those other universes.)

Woodbridge Professor of Philosophy at Columbia University. His research involves a number of topics within the foundations of physics, including the arrow of time (coining the phrase “Past Hypothesis” for the low-entropy state of the early universe) and quantum mechanics. He is the author of a number of books, including Time and Chance, Quantum Mechanics and Experience, and After Physics.

This is really really really good. Rare lucid logical considerations of confusing dilemmas. Simply and clearly explained for monkeys.

so this is day 2 of listening to this podcast. I've listened to quite a few podcasts on quantum mechanics and this makes me way more confused which based on the advice I've gotten from other sources means I'm starting to understand it more 😂 for real though it would be great to hear this all again with a bit more structure because this is my third time listening

Jeremy Dixon Exactly. I'm a researcher in AI and the only video on quantum stuff I ever understood was this https://youtu.be/F_Riqjdh2oM because it's mostly accessible maths :)

Pedro Abreu LOL seems like that's because we have no fucking clue what's going on we just know the math works out
