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.

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.

To insult someone we call him "bestial." For deliberate cruelty and nature, "human" might be the greater insult.

Vegetation is the basic instrument the creator uses to set all of nature in motion.

The gross heathenism of civilization has generally destroyed nature, and poetry, and all that is spiritual.

I'm inspired by nature. Other artist's work is important for developing my perception.

There were no temples or shrines among us save those of nature.

All men are by nature equal, made all of the same earth by one Workman; and however we deceive ourselves, as dear unto God is the poor peasant as the mighty prince.

Nature is a temple in which living columns sometimes emit confused words. Man approaches it through forests of symbols, which observe him with familiar glances.

Thus first of all in His own person He sanctified, restored, and blessed human nature.

Consistency is found in that work whose whole and detail are suitable to the occasion. It arises from circumstance, custom, and nature.

It was he who impressed, time and again, the necessity of singing as nature intended, and - I remember - he constantly warned, don't let the public know that you work. So I went slowly. I never forced the voice.

Our purpose is simply to ask how theological principles can be shown to have usable secular analogues that throw light upon the nature of language.

What motivates me in art is the ugly and beautiful nature of the truth. It has to be truthful and honest, even if it is ugly and grotesque.

I was 48-years old before anybody talked me into it for medicinal purposes, instead of some of these drugs that they give you that will lead you to heart surgery and things of that nature.

Shuffling is the only thing which Nature cannot undo.

We are all several different people. There are different aspects of our nature that are competing.

Because the quality of living with nature and allowing it to manifest itself is different than the quality of living in a city, especially a dense city.

Nature's laws must be obeyed, and the period of decline begins, and goes on with accelerated rapidity.

All the perplexities, confusion and distress in America arise, not from defects in their Constitution or Confederation, not from want of honor or virtue, so much as from the downright ignorance of the nature of coin, credit and circulation.

Nature is my manifestation of God. I go to nature every day for inspiration in the day's work. I follow in building the principles which nature has used in its domain.

Man can never be a woman's equal in the spirit of selfless service with which nature has endowed her.

My connection with the Reich Ministers was of a purely official nature and was very infrequent.

This bored fantastic woman, with her animal nature, giving herself the pleasure of seeing her enemy struck down, not a particularly keen one for her because she is so weary of having all her desires satisfied.

From this bestial view that the human mind consists of only sense certainty, pleasure and pain, Locke developed an equally bestial theory of the nation. Man originally existed in a State of Nature of complete liberty.

Some of his own closeness to nature, his great love for human beings, was passed on by Whitman to all of us who knew and loved him.

He loves nature in spite of what it did to him.

My dream is to save women from nature.

Take a course in good water and air; and in the eternal youth of Nature you may renew your own. Go quietly, alone; no harm will befall you.

Why is it so painful to watch a person sink? Because there is something unnatural in it, for nature demands personal progress, evolution, and every backward step means wasted energy.

The salary of the chief executive of a large corporation is not a market award for achievement. It is frequently in the nature of a warm personal gesture by the individual to himself.
