We know from chaos theory that even if you had a perfect model of the world, you'd need infinite precision in order to predict future events. With sociopolitical or economic phenomena, we don't have anything like that. — Nassim Nicholas Taleb

When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter. — Albert Einstein

simply objective; somehow it's something more subtle than that. In some
sense it is veiled from us, but it has a structure that we can
understand. — John Polkinghorne

If [quantum theory] is correct, it signifies the end of physics as a science. — Albert Einstein

The dirty alliance between religious preachers and possessors of power brought the boon of prisons, gallows, knouts and above all such theories for the mankind. — Bhagat Singh
In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the "Mind of God" is cosmic music resonating in 11 dimensional hyperspace. — Michio Kaku
The individual is handicapped by coming face-to-face with a conspiracy so monstrous he cannot believe it exists. — J. Edgar Hoover

You didn't see me on television, you didn't see news stories about me. The kind of role that I tried to play was to pick up pieces or put together pieces out of which I hoped organization might come. My theory is, strong people don't need strong leaders. — Ella Baker
Education, you know, means broadening, advancing; and if you limit a teacher to only one side of anything, the whole country will eventually have only one thought, be one individual. I believe in teaching every aspect of every problem or theory. — John T. Scopes
Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors.

I have this theory that if one person can go out of their way to show compassion then it will start a chain reaction of the same. — Rachel Scott

There's a radical - and wonderful - new idea here... that all children could and should be inventors of their own theories, critics of other people's ideas, analyzers of evidence, and makers of their own personal marks on the world.
