Men love to wonder, and that is the seed of science.

All men are prepared to accomplish the incredible if their ideals are threatened.

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.

What I’m trying to do is, is to make a significant difference in space flight. And help make space flight accessible to almost anyone.

Men create gods after their own image, not only with regard to their form but with regard to their mode of life.

Up until the 1920s, everyone thought the universe was essentially static and unchanging in time.

Today’s scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.

Science is but an image of the truth.

It is not titles that honor men, but men that honor titles.

Is science of any value? I think a power to do something is of value. Whether the result is a good thing or a bad thing depends on how it is used, but the power is a value.

In order to arrive at knowledge of the motions of birds in the air, it is first necessary to acquire knowledge of the winds, which we will prove by the motions of water in itself, and this knowledge will be a step enabling us to arrive at the knowledge of beings that fly between the air and the wind.

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.

Many admire, few know.

Men must live and create. Live to the point of tears.

Many men have been capable of doing a wise thing, more a cunning thing, but very few a generous thing.

Men are only as great as they are kind.

The smaller the planets are, they are, other things being equal, of so much the greater density; for so the powers of gravity on their several surfaces come nearer to equality. They are likewise, other things being equal, of the greater density, as they are nearer to the sun.

Between men and women there is no friendship possible. There is passion, enmity, worship, love, but no friendship.

The only things one can admire at length are those one admires without knowing why.

Millions of people were inspired by the Apollo Program. I was five years old when I watched Apollo 11 unfold on television, and without any doubt it was a big contributor to my passions for science, engineering, and exploration.

Nothing new here, except my marrying, which to me is a matter of profound wonder.

Science is magic that works.

Science has revealed that the human body is made up of millions and millions of atoms… For example, I am made up of 5.8×10 27 atoms.

A queer fellow and a jolly fellow is the grasshopper. Up the mountains he comes on excursions, how high I don’t know, but at least as far and high as Yosemite tourists.

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.

I think my first thought on reaching the summit- of course, I was very, very pleased to be there, naturally – but my first thought was one of a little bit of surprise. I was a little bit surprised that here I was, Ed Hillary, on top of Mt. Everest. After all, this is the ambition of most mountaineers.

The most obvious characteristic of science is its application: the fact that, as a consequence of science, one has a power to do things. And the effect this power has had need hardly be mentioned. The whole industrial revolution would almost have been impossible without the development of science.

One of the things that we’re trying to do with Creative Labs and all our experiences is explore things that aren’t all tied to Facebook identity. Some things will be, but not everything will have to be, because there are some sets of experiences that are just better with other identities.

A person who is too nice an observer of the business of the crowd, like one who is too curious in observing the labor of bees, will often be stung for his curiosity.

Buy the ticket, take the ride.

The things most people want to know about are usually none of their business.

There is no subject so old that something new cannot be said about it.

Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.

If we knew what it was we were doing, it would not be called research, would it?

Often people display a curious respect for a man drunk, rather like the respect of simple races for the insane… There is something awe-inspiring in one who has lost all inhibitions.

Women have simple tastes. They get pleasure out of the conversation of children in arms and men in love.

I spent more time on dark ships in danger zones than any other woman in the world.

How do I confront aging? With a wonder and a terror. Yeah, I’ll say that. Wonder and terror.

Romance should never begin with sentiment. It should begin with science and end with a settlement.

Creationists make it sound as though a ‚theory‘ is something you dreamt up after being drunk all night.

Because atomic behavior is so unlike ordinary experience, it is very difficult to get used to, and it appears peculiar and mysterious to everyone – both to the novice and to the experienced physicist.

I used to think information was destroyed in black hole. This was my biggest blunder, or at least my biggest blunder in science.

You want to play another kind of character in another genre, and it’s been something I’ve been trying to do if I can in the career so far, and it’s something I hope to continue because it’s interesting to me and you get to do different things as an actor.

Nobody climbs mountains for scientific reasons. Science is used to raise money for the expeditions, but you really climb for the hell of it.

I read the ‚Old Testament‘ all the way through when I was about 13 and was horrified. A few months afterwards I read ‚The Origin Of Species‘, hallucinating very mildly because I was in bed with flu at the time. Despite that, or because of that, it all made perfect sense.

Always the beautiful answer who asks a more beautiful question.

Men do change, and change comes like a little wind that ruffles the curtains at dawn, and it comes like the stealthy perfume of wildflowers hidden in the grass.

Men have become the tools of their tools.

Men’s actions are too strong for them. Show me a man who has acted, and who has not been the victim and slave of his action.

Curiosity killed the cat, but for a while I was a suspect.

I’m someone who likes plowing new ground, then walking away from it. I get bored easily. For me, the big thrill comes with the discovering.

Cosmology is a rapidly advancing field.

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

The mountains are calling and I must go.

The traveler sees what he sees, the tourist sees what he has come to see.

What women need to understand is that men don’t communicate. It’s not intentional or on purpose. We’re just not as emotional. You ladies feel like you have to express yourselves.

Men seldom, or rather never for a length of time and deliberately, rebel against anything that does not deserve rebelling against.

The big divide in this country is not between Democrats and Republicans, or women and men, but between talkers and doers.

I think all documentaries leave out areas of people’s lives. Which is good. There are areas that need not be explored.

When I’m really interested in something, I get superfocused on that. And I can spend hours upon hours not getting tired of reading about it and still be interested to learn more about it.

You find no man, at all intellectual, who is willing to leave London. No, Sir, when a man is tired of London, he is tired of life; for there is in London all that life can afford.
