Richard P. Feynman Quotes

In my long experience, one thing I know is that truth is elusive.

The real truth is splintered and spread throughout time.

Truth is much too complicated to allow anything but approximations.

In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.

The color of truth is gray.

It's very hard to know what wisdom is.

As a reporter you tend to seek coherence from your subject or your source - it all needs to add up and make sense. In truth, in reality, there's often a great deal of murkiness and muddiness, confusion and contradiction.

Truth is a tendency.

The truth is rarely pure and never simple.

If you aren't confused by quantum physics, then you haven't really understood it

Both the old and new physics were dealing with shadow-symbols, but the new physics was forced to be aware of that fact - forced to be aware that it was dealing with shadows and illusions, not reality.

I like relativity and quantum theories because I don't understand them and they make me feel as if space shifted about like a swan that can't settle, refusing to sit still and be measured; and as if the atom were an impulsive thing always changing its mind.

Il n'est pas certain que tout soit incertain. (Translation: It is not certain that everything is uncertain.)

the truth is often a mixed message

Faith is not so much a binary pole as a quantum state, which tends to indeterminacy when closely examined.

Everything is true and not true about everything. That’s one thing I’ve learned.

The reverse side of truth has a hundred thousand shapes and no defined limits.

There are no whole truths: All truths are half-truths.

Maybe I don't believe things myself, as well. Truth is such a transient thing.

The birth of science as we know it arguably began with Isaac Newton's formulation of the laws of gravitation and motion. It is no exaggeration to say that physics was reborn in the early 20th-century with the twin revolutions of quantum mechanics and the theory of relativity.

Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things.

Confusion is a word we have invented for an order which is not understood.

It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.

Whatever you say it is, it isn't.
