Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle.
When I hear of Schrödinger's cat, I reach for my pistol.
The 'path' comes into existence only when we observe it.
In fact, the mere act of opening the box will determine the state of the cat, although in this case there were three determinate states the cat could be in: these being Alive, Dead, and Bloody Furious.
For nearly a hundred years, we have known that the material world is an illusion. Everything that seems solid - a rock, a tree, your body - is actually 99.999% empty space.
Somewhere around the place I've got an unfinished short story about Schrodinger's Dog; it was mostly moaning about all the attention the cat was getting.
The mathematics of quantum mechanics very accurately describes how our universe works. And it tells us our reality is continually branching into different possibilities, just like a coral.
Thus, the more precisely the position is determined, the less precisely the momentum is known, and conversely.
Everyone's heard of Erwin Schrodinger's famous thought experiment. You put a cat in a box with a bottle of poison, which many people would suggest is about as far as you need to go.
The electron, as it leaves the atom, crystallises out of Schrodinger's mist like a genie emerging from his bottle.
The discontinuous 'reduction of the wave packets' which cannot be derived from Schroedinger's equation is ... a consequence of the transition from the possible to the actual.
Physics has found no straight lines. Instead, the physical universe consists of only waves undulating back and forth allowing for corrections and balance.
In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.
If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.
Physics should represent a reality in time and space, free from spooky action at a distance.
An atom is a hierarchy of different states of information that define the statistical likelihood of finding a particle here or there at the time of observation.
Faith is not so much a binary pole as a quantum state, which tends to indeterminacy when closely examined.
Can quantum mechanics represent the fact that an electron finds itself approximately in a given place and that it moves approximately with a given velocity, and can we make these approximations so close that they do not cause experimental difficulties?
It seems to me that all the things we keep in sealed boxes are both alive and dead until we open the box, that the unobserved is both there and not.
