Of course not ... but I am told it works even if you don't believe in it. - Niels Bohr

However far the phenomena transcend the scope of classical physical explanation, the account of all evidence must be expressed in classical terms. The argument is that simply by the word "experiment" we refer to a situation where we can tell others what we have done and what we have learned and that, therefore, the account of the experimental arrangement and of the results of the observations must be expressed in unambiguous language with suitable application of the terminology of classical physics.

In quantum mechanics...an observation here and now changes in general the 'state' of the observed system....I consider the unpredictable change of the state by a single observation...to be an abandonment of the idea of the isolation of the observer from the course of physical events outside himself.

An expert is a person who has found out by his own painful experience all the mistakes that one can make in a very narrow field.
