Quantum mechanics is a probabilistic theory that does not describe individual events. Yet when we perform a single measurement, we find a well-defined outcome. This apparent contradiction, known as ...

What follows is a fairly complete transcript of a discussion about quantum physics on May 19, 1994, the last day of a workshop in Santa Fe, N.M. It begins with some technical issues, posed by John ...

This morning on BBC Radio 4, the mathematician Roger Penrose, physicist Basil Hiley, and philosopher Simon Saunders had a lively discussion about the “measurement problem in physics” with broadcaster ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...
