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.

Force is the vital principle and immediate parent of despotism.

Justice without force is powerless; force without justice is tyrannical.

Sing me a new song; the world is transfigured; all the Heavens are rejoicing.

If a projectile were deprived of the force of gravity, it would not be deflected toward the earth but would go off in a straight line into the heavens and do so with uniform motion, provided that the resistance of the air were removed.

If the United Nations once admits that international disputes can be settled by using force, then we will have destroyed the foundation of the organization and our best hope of establishing a world order.

The moon gravitates towards the earth and by the force of gravity is continually drawn off from a rectilinear motion and retained in its orbit.

Weight, force and casual impulse, together with resistance, are the four external powers in which all the visible actions of mortals have their being and their end.

Freedom is a man’s natural power of doing what he pleases, so far as he is not prevented by force or law.

All the rivers run into the sea; yet the sea is not full.

We are tied to the ocean. And when we go back to the sea, whether it is to sail or to watch – we are going back from whence we came.

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.

We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances.

If you are not prepared to use force to defend civilization, then be prepared to accept barbarism.

You cannot control your own population by force, but it can be distracted by consumption.

Non-violence is the greatest force at the disposal of mankind. It is mightier than the mightiest weapon of destruction devised by the ingenuity of man.

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.

Peace cannot be kept by force; it can only be achieved by understanding.

Art is individualism, and individualism is a disturbing and disintegrating force.

What goes up must come down.

Nature has always had more force than education.

An object in motion tends to remain in motion along a straight line unless acted upon by an outside force.

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

To practice five things under all circumstances constitutes perfect virtue; these five are gravity, generosity of soul, sincerity, earnestness, and kindness.

The American President resembles the commander of a ship at sea. He must have a helm to grasp, a course to steer, a port to seek.

Law, without force, is impotent.

We are the miracle of force and matter making itself over into imagination and will. Incredible. The Life Force experimenting with forms. You for one. Me for another. The Universe has shouted itself alive. We are one of the shouts.

Gravity may put the planets into motion, but without the divine Power, it could never put them into such a circulating motion as they have about the Sun; and therefore, for this as well as other reasons, I am compelled to ascribe the frame of this System to an intelligent Agent.

It is important to emphasize that guerrilla warfare is a war of the masses, a war of the people. The guerrilla band is an armed nucleus, the fighting vanguard of the people. It draws its great force from the mass of the people themselves.

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.

The hypothesis of matter’s being at first evenly spread through the heavens is, in my opinion, inconsistent with the hypothesis of innate gravity without a supernatural power to reconcile them, and therefore, it infers a deity.

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.

Force always attracts men of low morality.

In my view of the present aspect of affairs, there is no need of bloodshed and war. There is no necessity for it. I am not in favor of such a course, and I may say in advance, there will be no blood shed unless it be forced upon the government. The government will not use force unless force is used against it.

Capitalism has destroyed our belief in any effective power but that of self interest backed by force.

I grew up with the sea, and poverty for me was sumptuous; then I lost the sea and found all luxuries gray and poverty unbearable.

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

Hate and force cannot be in just a part of the world without having an effect on the rest of it.

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.

I love the sea.

For life and death are one, even as the river and the sea are one.

I don’t think that faith, whatever you’re being faithful about, really can be scientifically explained. And I don’t want to explain this whole life business through truth, science. There’s so much mystery. There’s so much awe.

To rule children by force is the technique of Satan, not of the Savior.

If we have to use force, it is because we are America. We are the indispensable nation. We stand tall. We see further into the future.

Concupiscence and force are the source of all our actions; concupiscence causes voluntary actions, force involuntary ones.

The fishermen know that the sea is dangerous and the storm terrible, but they have never found these dangers sufficient reason for remaining ashore.

You can’t blame gravity for falling in love.

The magical, supernatural force that is with us every second is time. We can’t even comprehend it. It’s such an illusion, it’s such a strange thing.

People are underestimating the force of angry kids.

Just as the system of the sun, planets and comets is put in motion by the forces of gravity, and its parts persist in their motions, so the smaller systems of bodies also seem to be set in motion by other forces and their particles to be variously moved in relation to each other and, especially, by the electric force.

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.

Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more.

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.

Principles have no real force except when one is well-fed.

Gravity must be caused by an Agent acting constantly according to certain laws, but whether this Agent be material or immaterial I have left to the consideration of my readers.

Though force can protect in emergency, only justice, fairness, consideration and cooperation can finally lead men to the dawn of eternal peace.

Desire and force between them are responsible for all our actions; desire causes our voluntary acts, force our involuntary.

The virtues are lost in self-interest as rivers are lost in the sea.

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.

All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction.
