Albert Einstein
The only real valuable thing is intuition.
Albert Einstein
A theory can be proved by experiment; but no path leads from experiment to the birth of a theory.
Albert Einstein
When you sit with a nice girl for two hours, you think it`s only a minute. But when you sit on a hot stove for a minute, you think it`s two hours. That`s relativity.
Albert Einstein
Science is facts; just as houses are made of stones, so is science made of facts; but a pile of stones is not a house and a collection of facts is not necessarily science.
Jules Henri Poincare
If I have ever made any valuable discoveries, it has been owing more to patient observation than to any other reason.
Isaac Newton
When I examine myself and my methods of thought, I come to the conclusion that the gift of fantasy has meant more to me than my talent for absorbing positive knowledge.
Albert Einstein
As far as the laws of mathematics refer to reality, they are not certain, and as far as they are certain, they do not refer to reality.
Albert Einstein
No amount of experimentation can ever prove me right; a single experiment can prove me wrong.
Albert Einstein
Your theory is crazy, but it`s not crazy enough to be true.
Niels Bohr
Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone.
Albert Einstein
He who loves practice without theory is like the sailor who boards ship without a rudder and compass and never knows where he may cast.
