Quantum randomness

'Anyone who has not shocked by Quantum theory has not understood it' Niels Bohr 1885-1962

The world was apparently turned inside-out with quantum physics and I love the idea that particles more than light years apart are somehow in sync or communicating and that the certainty of the physical world may not be as certain as we think.

BUT

The physical world is pretty dependable.  If I leave something on the clothes line it is there or i can usually find it or there is a very clear physical explanation of where it has gone. Of course car keys are not always where I leave them but that may be random failures in my brain.

So yes I am shocked but at the same time I don't understand how Quantum theory affects the physical world I live in.
