Measure for Measure: Quantum Physics and Reality

                





Measure for Measure: Quantum Physics and Reality 

Δημοσιεύτηκε στις 20 Ιουν 2014

When
no one is looking, a particle has near limitless potential: it can be
nearly anywhere. But measure it, and the particle snaps to one position.
How do subatomic objects shed their quantum weirdness? Experts in the
field of physics, including David Z. Albert, Sean Carroll, Sheldon
Goldstein, Ruediger Schack, and moderator Brian Greene, discuss the
history of quantum mechanics, current theories in the field, and
possibilities for the future.
