Physicists Want to Rebuild Quantum Theory From Scratch:
"Some physicists just shrug and say we have to live with the fact that quantum
mechanics is weird. So particles can be in two places at once, or communicate
instantaneously over vast distances? Get over it. After all, the theory works fine. If you
want to calculate what experiments will reveal about subatomic particles, atoms,
molecules and light, then quantum mechanics succeeds brilliantly.
But some researchers want to dig deeper. They want to know why quantum mechanics
has the form it does, and they are engaged in an ambitious program to find out. It is
called quantum reconstruction, and it amounts to trying to rebuild the theory from
scratch based on a few simple principles."
