What Are the Foundational Issues in Quantum Mechanics?

TL;DR

The foundational issues in quantum mechanics include the measurement problem, which highlights how observing subatomic particles leads to paradoxical outcomes. Additionally, the spatialization of time in physics contrasts with our everyday understanding, suggesting that fundamental physical laws do not distinguish between past and future, revealing deeper complexities in the nature of time and reality.

David Albert: I'm David Albert. I'm a professor of philosophy at Columbia University. And my research is mostly concerned with issues of the foundations of physics. Question: What is the role of a philosopher of science? David Albert: Well, I think that philosophy of science is at its best and at its most exciting at historical moments when it's no... Read More
