In experimental philosophy, we are to look upon propositions inferred by general induction from phenomena as accurately or very nearly true, notwithstanding any contrary hypotheses that may be imagined, till such time as other phenomena occur by which they may either be made more accurate or liable to exceptions.

Science is beautiful when it makes simple explanations of phenomena or connections between different observations. Examples include the double helix in biology and the fundamental equations of physics.

Being politically correct means saying what’s polite rather than what’s accurate. I like to be accurate.

I’ve taken countless shots in my life, so you know the ones when you’re in rhythm, with a perfect release, and it’s on track, that it’s going in.

If anyone offers conjectures about the truth of things from the mere possibility of hypotheses, I do not see by what stipulation anything certain can be determined in any science, since one or another set of hypotheses may always be devised which will appear to supply new difficulties.

Quote me as saying I was mis-quoted.

Early in life I had noticed that no event is ever correctly reported in a newspaper.

The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.

In the United States, one of the main topics of academic political science is the study of attitudes and policy and their correlation. The study of attitudes is reasonably easy in the United States: heavily-polled society, pretty serious and accurate polls, and policy you can see, and you can compare them.

I’m here as a product of process of evolution, which doesn’t make very many exceptions. And which rates life relatively cheaply.

Physics has a history of synthesizing many phenomena into a few theories.

If you’re doing a biography, you try to stay as accurate as possible to reality. But you really don’t know what was going on in the person’s mind. You just know what was going on in the minds of people around him.

Men were not intended to work with the accuracy of tools, to be precise and perfect in all their actions.

Hypotheses should be subservient only in explaining the properties of things but not assumed in determining them, unless so far as they may furnish experiments.

I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity.

Gravitation is, so far, not understandable in terms of other phenomena.

Even a stopped clock is right twice a day.

Beautiful sentences pop into my head. Beautiful sentences that aren’t always absolutely accurate. Then, I have to choose between the beautiful sentence and being absolutely accurate. It can be a difficult choice.

From the point of view of basic physics, the most interesting phenomena are, of course, in the new places, the places where the rules do not work – not the places where they do work! That is the way in which we discover new rules.

Dictionaries are like watches, the worst is better than none and the best cannot be expected to go quite true.

I should like to know if, taking this old Declaration of Independence, which declares that all men are equal upon principle, you begin making exceptions to it, where will you stop? If one man says it does not mean a Negro, why not another say it does not mean some other man?

I didn’t take many penalties, but I never missed one.

The best and safest method of philosophizing seems to be first to inquire diligently into the properties of things, and establishing those properties by experiments, and then to proceed more slowly to hypotheses for the explanation of them.

With the exception of gravitation and radioactivity, all of the phenomena known to physicists and chemists in 1911 have their ultimate explanation in the laws of quantum electrodynamics.

Working out another system to replace Newton’s laws took a long time because phenomena at the atomic level were quite strange. One had to lose one’s common sense in order to perceive what was happening at the atomic level.

Ezra was right half the time, and when he was wrong, he was so wrong you were never in any doubt about it.

The power of accurate observation is commonly called cynicism by those who have not got it.

Electrical science has disclosed to us the more intimate relation existing between widely different forces and phenomena and has thus led us to a more complete comprehension of Nature and its many manifestations to our senses.

Justice and truth are too such subtle points that our tools are too blunt to touch them accurately.

Oh, the difference between nearly right and exactly right.

We know accurately only when we know little, with knowledge doubt increases.
