Quantum physics is no longer an abstract theory for specialists. We must now absolutely include it in our education and also in our culture.
Claude Cohen Tannoudji
If the evidence says youre wrong, you dont have the right theory. You change the theory, not the evidence.
John Kilian Houston Brunner
If you cant think of an observation that could disprove a theory, that theory simply isnt scientific.
Jerry Coyne
A single test which proves some piece of theory wrong is more valuable than a hundred tests showing that idea might be true.
William Clark
...talent and genius operate outside the rules, and theory conflicts with practice.
Carl von Clausewitz
Mainstream economics scholarship produces theory without facts ("pure theory") and facts without theory ("applied economics")
Michel Chossudovsky
I have this theory that anything that happens to you that leaves you alive and intact can be used somewhere in your writing.
Octavia E. Butler
We are all agreed that your theory is crazy. The question that divides us is whether it is crazy enough to have a chance of being correct.
Niels Henrik David Bohr
Anyone who is not shocked by quantum theory has not understood it.
Niels Henrik David Bohr
A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience.
Maurice Flix Charles Allais
In the theory of gender I began from zero. There is no masculine power or privilege I did not covet. But slowly, step by step, decade by decade, I was forced to acknowledge that even a woman of abnormal will cannot escape her hormonal identity.
Camille Paglia
My pacifism is an instinctive feeling, a feeling that possesses me because the murder of men is disgusting. My attitude is not derived from any intellectual theory but is based on my deepest antipathy to every kind of cruelty and hatred.
Albert Einstein
No theory, no ready-made system, no book that has ever been written will save the world. I cleave to no system. I am a true seeker.
Mikhail Alexandrovich Bakunin
