Real sign of intelligence isn't knoweldge, it's imagination

Time has no independent existence apart from the order of events by which we measure it.

I have always disliked the fierce competitive spirit embodied in that highly intellectual game.

If you do the same thing over and over again you cannot ever expect a different outcome.

The work on satisfactory formulation of technical patents was a true blessing for me. It compelled me to be many-sided in thought, and also offered important stimulation for thought about physics. Following a practical profession is a blessing for people of my type. Because the academic career puts a young person in a sort of compulsory situation to produce scientific papers in impressive quantity, a temptation to superficiality arises that only strong characters are able to resist.

It is my inner conviction that the development of science seeks in the main to satisfy the longing for pure knowledge.

Reading, after a certain age, diverts the mind too much from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking.
