Quantum Reality #4

"The many worlds interpretation"

Put forth by H. Everett in 1957, it suggests that the wave function never collapses -- that every possible event actually occurs, either in "our" world or in some instantaneously created "alternative universe."

Quantum Reality #5

"Quantum Logic"

What Einstein did to Euclidean geometry, some Quantum physicist/mathematicians hope to do to Boolean (Classical) Logic. Basically a doctrine of chance. It seems like a good idea.

Quantum Reality #6

"Neo-realism."

Einstein, Planck, Schrodinger, Bohm & de Broglie have all looked for ways to "save the phenomena," to discover & describe Quantum Reality intrinsically, rather than take the pesky step of agreeing with the Copenhagen school of anti-realisms ("Atoms are not things" said Heisenberg. "There is no quantum world" said Bohr.) Reconciling the neo-realist project with Quantum facts leads to some fantastic revelations, such as maintaining that the world is real but "non-local." It's very possible the quarrel between anti-realists & neo-realists arises from a semantic problem about the definition of "reality." Both sides claim that reality means Classical reality. In that sense, the Copenhagen group is forced to deny that ordinary objects exist. The neo-realists are reduced to merely looking for loopholes in Quantum Mechanics, & seem so far to have been foiled. But what if a Quantum Reality & an ordinary reality are both real? Simply modes of a single reality? Dichotomy vanishes. String Theorists appear...everyone runs away!
