Proof is an idol before which the mathematician tortures himself.
I don’t believe any experiment until it is confirmed by theory. I find this is a witty inversion of “conventional” wisdom.
In any attempt to bridge the domains of experience belonging to the spiritual and physical sides of nature, time occupies the key position.
What is possible in the Cavendish Laboratory may not be too difficult in the sun.
Don’t believe the results of experiments until they’re confirmed by theory.
It is a primitive form of thought that things exist or do not exist.
For the truth of the conclusions of physical science, observation is the supreme Court of Appeal.
Life would be stunted and narrow if we could feel no significance in the world around us beyond that which can be weighed and measured with the tools of the physicist or described by the metrical symbols of the mathematician.
So far as physics is concerned, time’s arrow is a property of entropy alone.
It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.
I believe there are 15, 747, 724, 136, 275, 002, 577, 605, 653, 961, 181, 555, 468, 044, 717, 914, 527, 116, 709, 366, 231, 425, 076, 185, 631, 031, 296 protons in the universe and the same number of electrons.
Human life is proverbially uncertain; few things are more certain than the solvency of a life-insurance company.
The physical world is entirely abstract and without actuality apart from its linkage to consciousness.
Shuffling is the only thing which Nature cannot undo.
Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own fingers.
In Einstein’s theory of relativity the observer is a man who sets out in quest of truth armed with a measuring-rod. In quantum theory he sets out with a sieve.
We have found that where science has progressed the farthest, the mind has but regained from nature that which the mind put into nature.
The word reality frightens me.
Never accept a fact until it has been verified by theory.
Electrical force is defined as something which causes motion of electrical charge; an electrical charge is something which exerts electric force.
