Often one postulates that a priori, all states are equally probable. This is not true in the world as we see it. This world is not correctly described by the physics which assumes this postulate.

Men who wish to know about the world must learn about it in its particular details.

Quarks came in a number of varieties – in fact, at first, only three were needed to explain all the hundreds of particles and the different kinds of quarks – they are called u-type, d-type, s-type.

Methods of thought which claim to give the lead to our world in the name of revolution have become, in reality, ideologies of consent and not of rebellion.

The drawing teacher has this problem of communicating how to draw by osmosis and not by instruction, while the physics teacher has the problem of always teaching techniques, rather than the spirit, of how to go about solving physical problems.

The progress of India is the destiny of one-sixth of humanity. And it will also mean a world more confident of its prosperity and more secure about its future.

I am not enough of a mathematician to be able to judge either the well-foundedness or the limits of relativity in physics.

The observer, when he seems to himself to be observing a stone, is really, if physics is to be believed, observing the effects of the stone upon himself.

There is love enough in this world for everybody, if people will just look.

The true and the approximately true are apprehended by the same faculty; it may also be noted that men have a sufficient natural instinct for what is true, and usually do arrive at the truth. Hence the man who makes a good guess at truth is likely to make a good guess at probabilities.

I hope I have helped to raise the profile of science and to show that physics is not a mystery but can be understood by ordinary people.

We have the power to make this the best generation of mankind in the history of the world or to make it the last.

I think equation guessing might be the best method to proceed to obtain the laws for the part of physics which is presently unknown. Yet, when I was much younger, I tried this equation guessing, and I have seen many students try this, but it is very easy to go off in wildly incorrect and impossible directions.

That is what fame is, isn’t it? To get the world to fall in love with you.

It’s a funny old world.

The average age of the world’s greatest civilizations from the beginning of history has been about 200 years.

Society therefore is as ancient as the world.

A myth is an image in terms of which we try to make sense of the world.

The same thing is to be understood of all bodies, revolved in any orbits. They all endeavour to recede from the centres of their orbits, and were it not for the opposition of a contrary force which restrains them to and detains them in their orbits, which I therefore call Centripetal, would fly off in right lines with a uniform motion.

It is comforting to reflect that the disproportion of things in the world seems to be only arithmetical.

Unless India stands up to the world, no one will respect us. In this world, fear has no place. Only strength respects strength.

‚Tis love that makes the world go round, my baby.

The fundamental concept in social science is Power, in the same sense in which Energy is the fundamental concept in physics.

The wide world is all about you: you can fence yourselves in, but you cannot forever fence it out.

I’ve got a feeling that music might not be the most interesting place to be in the world of things.

Fiction is such a world of freedom, it’s wonderful. If you want someone to fly, they can fly.

What is this world that is hastening me toward I know not what, viewing me with contempt?

The world is all gates, all opportunities, strings of tension waiting to be struck.

No one undertakes research in physics with the intention of winning a prize. It is the joy of discovering something no one knew before.

This world is but a canvas to our imagination.

The probability that we may fail in the struggle ought not to deter us from the support of a cause we believe to be just.

I tend to approach things from a physics framework. And physics teaches you to reason from first principles rather than by analogy.

My favorite time in the cycles of public life is the time when the Pope is dead and they haven’t elected a new one. There’s no one in the world who is infallible for those weeks. And you know, I don’t miss it.

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

Were there none who were discontented with what they have, the world would never reach anything better.

When my dad founded our church, he used either a globe or a map of the world behind him. It was symbolic of what Christ said: to go forth and preach hope to the world. We believe in the cross, but we just continued with the globe.

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

My first popular book, ‚A Brief History of Time,‘ aroused a great deal of interest, but many found it difficult to understand.

It is reasonable that forces directed toward bodies depend on the nature and the quantity of matter of such bodies, as happens in the case of magnetic bodies.

First and foremost comes my family and my life with Brad. We have so much joy in raising our children and teaching them about the world that nothing really compares to that.

M-theory is the unified theory Einstein was hoping to find.

We have got to change our ethics and our financial system and our whole way of understanding the world. It has to be a world in which people live rather than die; a sustainable world. It could be great.

I was born into the world as the king of truth for the salvation of the world.

The fashion of the world is to avoid cost, and you encounter it.

Chemistry, until my childhood, not that long ago, was regarded as a calculating device. Because you couldn’t reduce to physics. So it’s just some way of calculating the result of experiments. The Bohr atom was treated that way.

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.

I am the astronaut of boxing. Joe Louis and Dempsey were just jet pilots. I’m in a world of my own.

In some sort of crude sense, which no vulgarity, no humor, no overstatement can quite extinguish, the physicists have known sin; and this is a knowledge which they cannot lose.

For ninety per cent of those who view him from outside, the Christian God looks like a great landowner administering his estates, the world. Now this conventional picture, which is too well justified by appearances, corresponds in no way to the dogmatic basis or point of view of the Gospels.

The theoretical understanding of the world, which is the aim of philosophy, is not a matter of great practical importance to animals, or to savages, or even to most civilised men.

Here’s what I believe, I think the FBI is the premier law enforcement agency in the history of the world but i think there was some bad apples over there.

The point in history at which we stand is full of promise and danger. The world will either move forward toward unity and widely shared prosperity – or it will move apart.

I suspect that even most conservatives would prefer to live in the kind of world conjured up in the liberals‘ imagination rather than in the kind of world we are in fact stuck with.

The world is full of hopeful analogies and handsome, dubious eggs, called possibilities.

The thing I really care about is the mission, making the world open.

Don’t let anybody make you think God chose America as His divine messianic force to be a sort of policeman of the whole world.

It was Einstein’s dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein’s day hadn’t made enough progress in understanding the forces of nature for that to be a realistic goal.

Nature is the incarnation of thought. The world is the mind precipitated.

Suffering is the positive element in this world, indeed it is the only link between this world and the positive.

This world, after all our science and sciences, is still a miracle wonderful, inscrutable, magical and more, to whosoever will think of it.

If you were to destroy the belief in immortality in mankind, not only love but every living force on which the continuation of all life in the world depended, would dry up at once.
