"This picture of material reality is today   more wavering and uncertain than it has been for a long time. We know a great many interesting details, learn new ones everey week. But to seek out among the basic ideas those which are actually established and to construct out of them a clear easily comprehensible framework of which it could be said: This is unquestionably the way things are, this we all believe today - that is simply impossible."

Erwin Schrödinger, 1952
