Windmills, which are used in the great plains of Holland and North Germany to supply the want of falling water, afford another instance of the action of velocity. The sails are driven by air in motion - by wind.

Each individual fact, taken by itself, can indeed arouse our curiosity or our astonishment, or be useful to us in its practical applications.

The older view of the nature of heat was that it is a substance, very fine and imponderable indeed, but indestructible, and unchangeable in quantity, which is an essential fundamental property of all matter.

I then endeavoured to show that it is more especially in the thorough conformity with law which natural phenomena and natural products exhibit, and in the comparative ease with which laws can be stated, that this difference exists.

Windmills, which are used in the great plains of Holland and North Germany to supply the want of falling water, afford another instance of the action of velocity. The sails are driven by air in motion - by wind.

Heat can also be produced by the impact of imperfectly elastic bodies as well as by friction. This is the case, for instance, when we produce fire by striking flint against steel, or when an iron bar is worked for some time by powerful blows of the hammer.

The law in question asserts, that the quantity of force which can be brought into action in the whole of Nature is unchangeable, and can neither be increased nor diminished.

Now, the external work of man is of the most varied kind as regards the force or ease, the form and rapidity, of the motions used on it, and the kind of work produced.

Iron which is brought near a spiral of copper wire, traversed by an electrical current, becomes magnetic, and then attracts other pieces of iron, or a suitably placed steel magnet.

Reason we call that faculty innate in us of discovering laws and applying them with thought.

What appeared to the earlier physicists to be the constant quantity of heat is nothing more than the whole motive power of the motion of heat, which remains constant so long as it is not transformed into other forms of work, or results afresh from them.

You all know how powerful and varied are the effects of which steam engines are capable; with them has really begun the great development of industry which has characterised our century before all others.

A raised weight can produce work, but in doing so it must necessarily sink from its height, and, when it has fallen as deep as it can fall, its gravity remains as before, but it can no longer do work.

A moving body whose motion was not retarded by any resisting force would continue to move to all eternity.

But heat can also be produced by the friction of liquids, in which there could be no question of changes in structure, or of the liberation of latent heat.

Not that I wish by any means to deny, that the mental life of individuals and peoples is also in conformity with law, as is the object of philosophical, philological, historical, moral, and social sciences to establish.

A metaphysical conclusion is either a false conclusion or a concealed experimental conclusion.

But heat can also be produced by the friction of liquids in which there could be no question of changes in structure or of the liberation of latent heat.

I did work out every day. I needed it to have the endurance to do what needed to be done and not get hurt. I have such a new respect for action stars now.

Good managers have a bias for action.

Oh yeah, I'm a huge romance fan. And some women like action.

If nothing is to be done in the given situation, he must invent plausible reasons for doing nothing; and if something must be done, he must suggest the something. The unpardonable sin is to propose nothing, when action is imperative.

The international proletariat first appeared on the scene in the early Thirties of the nineteenth century, and its first great action was the French Revolution of 1848.

To stop terrorists before the strike, we must do three things: deny them entry into the country, curtail their freedom of action inside the country, and deprive them of material and moral support from within the country.

Infuse your life with action. Don't wait for it to happen. Make it happen. Make your own future. Make your own hope. Make your own love. And whatever your beliefs, honor your creator, not by passively waiting for grace to come down from upon high, but by doing what you can to make grace happen... yourself, right now, right down here on Earth.

But the way people commonly use the word nowadays it means something all of whose parts are mutually interdependent - not only for their mutual action, but for their meaning and for their existence.

In any ethical situation, the thing you want least to do is probably the right action.

A man's action is only a picture book of his creed.

The time has come for the American government to recognize the damage that has occurred to our economy, and to take firm action to curtail what I believe is both unfair and illegal foreign competition.

The methods of peace propaganda which aim at establishing peace doctrine by argument and by creating a feeling favorable to peace in general seem to fall short of reaching the springs of human action and of dealing with the causes of the conduct which they seek to modify.

There are two good things in life - freedom of thought and freedom of action.

Sometimes the situation is only a problem because it is looked at in a certain way. Looked at in another way, the right course of action may be so obvious that the problem no longer exists.

You have to understand the tone of the movie, because if it's supposed to be funny, it can be funny violent like the Home Alone stuff, but you have to really understand the tone of what you're doing and make the action work for that and for the character.

It is funny that men who are supposed to be scientific cannot get themselves to realise the basic principle of physics, that action and reaction are equal and opposite, that when you persecute people you always rouse them to be strong and stronger.

The decision to go to war is the most important decision that I can make as a representative in Congress. As a veteran, I see any potential military action first through the eyes of the young men and women who volunteered to wear the uniform and would carry out such a mission.

The world can only be grasped by action, not by contemplation. The hand is the cutting edge of the mind.

I'd really like to get the girl, shoot the gun, drive the car, have fun. I even have these kind of action dreams, where I'm the action guy.

The time for action is now. It's never too late to do something.

I think that feeling that if one believed absolutely in any cause, then one must have the confidence, the self-certainty, to go through with that particular course of action.

It was never really my choice to be an action heroine.

Direct action is the logical, consistent method of Anarchism.

Deep within man dwell those slumbering powers; powers that would astonish him, that he never dreamed of possessing; forces that would revolutionize his life if aroused and put into action.

I think if you do something effectively whether you're the lover or the comic or the action guy or the villain like I play; movies are very expensive to make. Chances are you'll get asked to play that part again.

Example moves the world more than doctrine. The great exemplars are the poets of action, and it makes little difference whether they be forces for good or forces for evil.

He's looking for the president's kidnapped daughter; everybody he calls on to help him is busy, but lo and behold, you look across the room, and I'm waiting for that action.

Action is at bottom a swinging and flailing of the arms to regain one's balance and keep afloat.

There is no reality of consciousness independent of the effects of various vehicles of content on subsequent action (and hence, of course, on memory).

In the discharge of the duties of this office, there is one rule of action more important than all others. It consists in never doing anything that someone else can do for you.

Instead of the international police action we had hoped for during the war in Kosovo, there are wars again - conducted with state-of-the-art technology, but still in the old style.
