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 ...

It is possible that the view of consciousness that I have been exploring, that the mind-brain system is a quantum cohering-decohering-recohering system in an environment, may shed light on the mighty ...

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 ...

Many World’s lack wavefunction collapse might be the key to the measurement problem. The mystery of what happens when we go from a superposition to a definite state is known as the Measurement Problem ...

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 ...
