500+ Sourced quotes

We want to express physical laws in such a way that it shall be obvious when we are expressing the same law by reference to two different systems of co-ordinates, so that we shall not be misled into supposing we have different laws when we have one law in different words. This is accomplished by the method of tensors.

Bertrand Russell

Something was making him nibble at the edge of stale ideas as if his sturdy physical egotism no longer nourished his peremptory heart.

F. Scott Fitzgerald

It is not by muscle, speed, or physical dexterity that great things are achieved, but by reflection, force of character, and judgment.

A careful physician... before he attempts to administer a remedy to his patient, must investigate not only the malady of the man he wishes to cure, but also his habits when in health, and his physical constitution.

Women are quite able to make friends with a man; but to preserve such a friendship - that no doubt requires the assistance of a slight physical antipathy

Friedrich Nietzsche

We may sum up as follows: According to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, an ether exists. Space without an ether is inconceivable.

Albert Einstein

I design to speak of the Physical, Metaphysical and Mathematical — of the Material and Spiritual Universe: — of its Essence, its Origin, its Creation, its Present Condition and its Destiny.

Edgar Allan Poe

Robots will play an important role in providing physical assistance and even companionship for the elderly.

Doubtless, we are as slow to conceive of Paradise as of Heaven, of a perfect natural as of a perfect spiritual world. We see how past ages have loitered and erred. "Is perhaps our generation free from irrationality and error? Have we perhaps reached now the summit of human wisdom, and need no more to look out for mental or physical improvement?" Undoubtedly, we are never so visionary as to be prepared for what the next hour may bring forth.

Henry David Thoreau

The diversity of physical arguments and opinions embraces all sorts of methods.

Michel de Montaigne

If physical death is the price that some must pay to free their children and their white brothers from a permanent death of the spirit, then nothing can be more redemptive.

Martin Luther King, Jr.

Those pleasures so lightly called physical.

But if physical death is the price that a man must pay to free his children and his white brethren from a permanent death of the spirit, then nothing could be more redemptive. This is the type of soul force that I am convinced will triumph over the physical force of the oppressor.

Martin Luther King, Jr.

We cannot look upon our lives as dreams of a dreamer who has no awakening in all time. We have a personality to which matter and force are unmeaning unless related to something infinitely personal, whose nature we have discovered, in some measure, in human love, in the greatness of the good, in the martyrdom of heroic souls, in the ineffable beauty of nature, which can never be a mere physical fact nor anything but an expression of personality.

Rabindranath Tagore

It will be seen that we contemplate a time when man's will shall be law to the physical world, and he shall no longer be deterredby such abstractions as time and space, height and depth, weight and hardness, but shall indeed be the lord of creation.

Henry David Thoreau

A second way that oppressed people sometimes deal with oppression is to resort to physical violence and corroding hatred. Violence often brings about momentary results. Nations have frequently won their independence in battle. But in spite of temporary victories, violence never brings permanent peace. It solves no social problem; it merely creates new and more complicated ones.

Martin Luther King, Jr.

Although I'm regarded as a dangerous radical by particle physicists for proposing that there may be loss of quantum coherence, I'm definitely a conservative compared to Roger. I take the positivist viewpoint that a physical theory is just a mathematical model and that it is meaningless to ask whether it corresponds to reality. All that one can ask is that its predictions should be in agreement with observation. I think Roger [Penrose] is a Platonist at heart but he must answer for himself.

Stephen Hawking

I have always believed that a good laugh was good for both the mental and physical digestion.

Abraham Lincoln

In the visible world, the Milky Way is a tiny fragment; within this fragment, the solar system is an infinitesimal speck, and of this speck our planet is a microscopic dot. On this dot, tiny lumps of impure carbon and water, of complicated structure, with somewhat unusual physical and chemical properties, crawl about for a few years, until they are dissolved again into the elements of which they are compounded.

Bertrand Russell

"The physical world is real." That is supposed to be the fundamental hypothesis. What does "hypothesis" mean here? For me, a hypothesis is a statement, whose truth must be assumed for the moment, but whose meaning must be raised above all ambiguity. The above statement appears to me, however, to be, in itself, meaningless, as if one said: "The physical world is cock-a-doodle-do." It appears to me that the "real" is an intrinsically empty, meaningless category (pigeon hole), whose monstrous importance lies only in the fact that I can do certain things in it and not certain others.

Albert Einstein

Even men of the noblest possible moral character are extremely susceptible to the influence of the physical charms of others. Modern, no less then Ancient History, supplies us with many most painful examples of what I refer to. If it were not so, indeed, History would be quite unreadable.

Far better than emasculation would be the bravery of those who use physical force. Far better than cowardice would be meeting one's death fighting.

The spirit is the true self, not that physical figure which can be pointed out by your finger.

We are going to a new world... and no doubt it is there that everything is for the best; for it must be admitted that one might lament a little over the physical and moral happenings of our own world.

It has become entirely clear that we must have government supervision of the capitalization, not only of public-service corporations, including, particularly, railways, but of all corporations doing an interstate business. I do not wish to see the nation forced into the ownership of the railways if it can possibly be avoided, and the only alternative is thoroughgoing and effective legislation, which shall be based on a full knowledge of all the facts, including a physical valuation of property. This physical valuation is not needed, or, at least, is very rarely needed, for fixing rates; but it is needed as the basis of honest capitalization.

Theodore Roosevelt
