Those who are not shocked when they first come across quantum theory cannot possibly have understood it.
When searching for harmony in life one must never forget that in the drama of existence we are ourselves both actors and spectators.
And anyone who thinks they can talk about quantum theory without feeling dizzy hasn't yet understood the first thing about it.
Everything we call real is made of things that cannot be regarded as real.
We live in the midst of alarms; anxiety beclouds the future; we expect some new disaster with each newspaper we read.
The easiest thing to do on earth is not write.
