The credit of advancing science has always been due to individuals and never to the age.

Every strike brings me closer to the next home run.

Do the difficult things while they are easy and do the great things while they are small. A journey of a thousand miles must begin with a single step.

Cosmology is a rapidly advancing field.

Whatever America hopes to bring to pass in the world must first come to pass in the heart of America.

The history of science shows that theories are perishable. With every new truth that is revealed we get a better understanding of Nature and our conceptions and views are modified.

We have the resources to build room for a trillion humans in this solar system, and when we have a trillion humans, we’ll have a thousand Einsteins and a thousand Mozarts. It will be a way more interesting place to live.

Success is like reaching an important birthday and finding you’re exactly the same.

The X is an amazing car, but we kind of got carried away with the art and technology. Obviously, you want great art. You want great technology. But we did get a little distracted from our mission, which was to advance the cause of electric vehicles. And it probably delayed us a little bit with the Model 3 as well.

Every experiment, by multitudes or by individuals, that has a sensual and selfish aim, will fail.

Confusion of goals and perfection of means seems, in my opinion, to characterize our age.

Human progress is neither automatic nor inevitable… Every step toward the goal of justice requires sacrifice, suffering, and struggle; the tireless exertions and passionate concern of dedicated individuals.

Science never makes things that do not have to do with what we feel, by which I mean what we want and what we fear.

We must develop as quickly as possible technologies that make possible a direct connection between brain and computer, so that artificial brains contribute to human intelligence rather than opposing it.

The reason men oppose progress is not that they hate progress, but that they love inertia.

Of course humans like to explore, and we should. There’s nothing wrong with that. But it’s more than that. It’s essential for your children and your children’s children.

It’s different from being 21 and you think there’s endless amount of opportunities. At 33, the ending is much, much closer.

Until we’re educating every kid in a fantastic way, until every inner city is cleaned up, there is no shortage of things to do.

Science investigates; religion interprets. Science gives man knowledge which is power; religion gives man wisdom which is control.

It vexes me when they would constrain science by the authority of the Scriptures, and yet do not consider themselves bound to answer reason and experiment.

I believe you have to be willing to be misunderstood if you’re going to innovate.

Success is a science; if you have the conditions, you get the result.

America and Islam are not exclusive and need not be in competition. Instead, they overlap, and share common principles of justice and progress, tolerance and the dignity of all human beings.

So while an incredible amount of progress has been made, on this fifth anniversary, I wanted to come here and tell the people of this city directly: My administration is going to stand with you – and fight alongside you – until the job is done. Until New Orleans is all the way back, all the way.

I’m interested in what motivates individuals to participate in atrocious acts to support their ideological identification.

Life is a progress from want to want, not from enjoyment to enjoyment.

Philosophers have not kept up with modern developments in science. Particularly physics.

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

I have been on the road and visited numerous places and met people from all over the globe. I can say that it looks nearly the same everywhere I have been: The climate crisis is ignored by people in charge, despite the science being crystal clear.

You are 27 or 28 right? It is very tough to live at that age. When nothing is sure. I have sympathy with you.

You’ve got to vote, vote, vote, vote. That’s it; that’s the way we move forward. That’s how we make progress for ourselves and for our country.

The first amazing fact about gravitation is that the ratio of inertial mass to gravitational mass is constant wherever we have checked it. The second amazing thing about gravitation is how weak it is.

Science is a wonderful thing if one does not have to earn one’s living at it.

Both free speech rights and property rights belong legally to individuals, but their real function is social, to benefit vast numbers of people who do not themselves exercise these rights.

If we could do high-speed rail in California just half a notch above what they’ve done on the Shanghai line in China, and if we had a straight path from L.A. to San Francisco, as well as the milk run, at least that would be progress.

I’ve always been amazed by Da Vinci, because he worked out science on his own. He would work by drawing things and writing down his ideas. Of course, he designed all sorts of flying machines way before you could actually build something like that.

As long as a woman can look ten years younger than her own daughter, she is perfectly satisfied.

Developing nations want to become developed nations.

We are a forward-looking people, and we must have a forward-looking government.

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

Rockets are cool. There’s no getting around that.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not ‚Eureka!‘ but ‚That’s funny…‘

Of all the inventions of humans, the computer is going to rank near or at the top as history unfolds and we look back. It is the most awesome tool that we have ever invented. I feel incredibly lucky to be at exactly the right place in Silicon Valley, at exactly the right time, historically, where this invention has taken form.

Strength and growth come only through continuous effort and struggle.

Africa will thrive.

Progress is not an illusion, it happens, but it is slow and invariably disappointing.

I’m never going to go to Mars, but I’ve helped inspire, thank goodness, the people who built the rockets and sent our photographic equipment off to Mars.

We may never be strong enough to be entirely nonviolent in thought, word and deed. But we must keep nonviolence as our goal and make strong progress towards it.

New ideas pass through three periods: 1) It can’t be done. 2) It probably can be done, but it’s not worth doing. 3) I knew it was a good idea all along!

Well begun is half done.

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.

Even though you are on the right track – you will get run over if you just sit there.

Science is properly more scrupulous than dogma. Dogma gives a charter to mistake, but the very breath of science is a contest with mistake, and must keep the conscience alive.

Men of age object too much, consult too long, adventure too little, repent too soon, and seldom drive business home to the full period, but content themselves with a mediocrity of success.

And so our goal on health care is, if we can get, instead of health care costs going up 6 percent a year, it’s going up at the level of inflation, maybe just slightly above inflation, we’ve made huge progress. And by the way, that is the single most important thing we could do in terms of reducing our deficit. That’s why we did it.

I do not believe in God; his existence has been disproved by Science. But in the concentration camp, I learned to believe in men.

If you think the United States has stood still, who built the largest shopping center in the world?

As scientists, we step on the shoulders of science, building on the work that has come before us – aiming to inspire a new generation of young scientists to continue once we are gone.

I never wanted to be a scientist per se. I wanted to be a naturalist.

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein’s general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

I had no talent for science. What was infinitely worse: all my fraternity brothers were engineers.
