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

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.

A great thing happening now in art is that artists are using the figure, the body, clothing, life.

Common sense should tell us that there is no reason for civilians to have access to easily concealable handguns with the capability to shoot through body armor.

Well, the years from 10 to 20, when your body, mind and everything is like changing every five minutes, can be pretty torturing. And most of the interesting characters, I think, are somewhat tortured or torturous. I'm 20 now, so I'm only just an adult.

If you read quickly to get through a poem to what it means, you have missed the body of the poem.

I figured my body always would be able to repair itself. I think all of us believe that - until you begin to age and get hit with deteriorating joints.

I look at the story, I look at the idea and just try to think of it in terms of that whole body of myth and see where the characters fit in and what they ought to be doing-all those archetypes are there to play with.
