Isaac Newton Quotes

Thus you may multiply each stone 4 times & no more for they will then become oyles shining in ye dark and fit for magicall uses. You may ferment them with gold and silver, by keeping the stone and metal in fusion together for a day, & then project upon metalls. This is the multiplication of ye stone in vertue. To multiply it in weight ad to it of ye first Gold whether philosophic or vulgar. ~ Isaac Newton

Every body persists in a state of rest or of uniform motion in a straight line, unless it is compelled to change that state by forces having impact upon it. ~ Isaac Newton

OUR ORDINATION:

Sir Isaac Newton, 1642 – 1747
About the times of the End, a body of men will be raised up who will turn their attention to the prophecies, and insist upon their literal interpretation, in the midst of much clamor and opposition. ~ Isaac Newton

My powers are ordinary. Only my application brings me success. ~ Isaac Newton

What is there in places empty of matter? and Whence is it that the sun and planets gravitate toward one another without dense matter between them? Whence is it that Nature doth nothing in vain? and Whence arises all that order and beauty which we see in the world? To what end are comets? and Whence is it that planets move all one and the same way in orbs concentrick, while comets move all manner of ways in orbs very excentrick? and What hinders the fixed stars from falling upon one another? ~ Isaac Newton

Infinites, when considered absolutely without any restriction or limitation, are neither equal nor unequal, nor have any certain proportion one to another, and therefore, the principle that all infinites are equal is a precarious one. ~ Isaac Newton

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. ~ Isaac Newton

Blind metaphysical necessity, which is certainly the same always and every where, could produce no variety of things. All that diversity of natural things which we find suited to different times and places could arise from nothing but the ideas and will of a Being, necessarily existing. ~ Isaac Newton

I am ashamed to tell you to how many figures I carried these calculations [of Pi], having no other business at the time ~ Isaac Newton

[1.] And first I suppose that there is diffused through all places an aethereal substance capable of contraction & dilatation, strongly elastick, & in a word, much like air in all respects, but far more subtile. 2. I suppose this aether pervades all gross bodies, but yet so as to stand rarer in their pores then in free spaces, & so much ye rarer as their pores are less ... 3. I suppose ye rarer aether within bodies & ye denser without them, not to be terminated in a mathematical superficies, but to grow gradually into one another. ~ Isaac Newton

For it became him [God] who created them [the atoms] to set them in order. And if he did so, it's unphilosophical to seek for any other Origin of the World, or to pretend that it might arise out of a Chaos by the mere Laws of Nature. ~ Isaac Newton

Newton supposed that the case of the planet was similar to that of [a ball spun around on the end of an elastic string]; that it was always pulled in the direction of the sun, and that this attraction or pulling of the sun produced the revolution of the planet, in the same way that the traction or pulling of the elastic string produces the revolution of the ball. What there is between the sun and the planet that makes each of them pull the other, Newton did not know; nobody knows to this day; and all we are now able to assert positively is that the known motion of the planet is precisely what would be produced if it were fastened to the sun by an elastic string, having a certain law of elasticity. Now observe the nature of this discovery, the greatest in its consequences that has ever yet been made in physical science: -

I. It begins with an hypothesis, by supposing that there is an analogy between the motion of a planet and the motion of a ball at the end of a string.

II. Science becomes independent of the hypothesis, for we merely use it to investigate the properties of the motion, and do not trouble ourselves further about the cause of it. ~ William Kingdon Clifford

If others would think as hard as I did, then they would get similar
results. ~ Isaac Newton

To explain all nature is too difficult a task for any one man or even for any one age. Tis much better to do a little with certainty & leave the rest for others that come after than to explain all things by conjecture without making sure of any thing. ~ Isaac Newton

I'd go back and hang out with Isaac Newton. I'm torn between do I hang out with him or do I bring him into the present to hang out with me. See, that might be terrifying because his head will just explode once he sees everything that was derived from his discoveries, but I'd spend more time with someone who I think is one of the most brilliant minds our species has ever known. ~ Neil DeGrasse Tyson

God gave the prophecies, not to gratify men's curiosity by enabling them to fore know things, but that after they were fulfilled they might be interpreted by the event, and His own providence, not the interpreters, be thereby manifested to the world. ~ Isaac Newton

He that in ye mine of knowledge deepest diggeth, hath, like every other miner, ye least breathing time, and must sometimes at least come to terr. alt. for air. ~ Isaac Newton

Doth not this Aethereal Medium in passing out of Water, Glass, Crystal, and other compact and dense Bodies into empty Spaces, grow denser and denser by degrees, and by that means refract the Rays of Light not in a point, but by bending them gradually in curve Lines? And doth not the gradual condensation of this Medium extend to some distance from the Bodies, and thereby cause the Inflexions of the Rays of Light, which pass by the edges of dense Bodies, at some distance from the Bodies? ~ Isaac Newton

What the Latins have done in this text (1 John v, 7) the Greeks have done to Paul (1 Tim. iii, 16). They now read, "Great is the mystery of godliness; God manifest in the flesh"; whereas all the churches for the first four or five hundred years, and the authors of all the ancient versions, Jerome as well as the rest, read, "Great is the mystery of godliness, which was manifest in the flesh." Our English version makes it yet a little stronger. It reads, "Great is the mystery of godliness: God was manifest in the flesh." ~ Isaac Newton

For I see not what there is desirable in publick esteeme, were I able to acquire & maintaine it. It would perhaps increase my acquaintance, the thing which I chiefly study to decline. ~ Isaac Newton

The changing of Bodies into Light, and Light into Bodies, is very conformable to the Course of Nature, which seems delighted with Transmutations. ~ Isaac Newton

The kingdoms represented by the second and third Beasts, or the Bear and Leopard, are again described by Daniel in his last Prophecy written in the third year of Cyrus over Babylon , the year in which he conquered Persia. For this Prophecy is a commentary upon the Vision of the Ram and He-Goat. ~ Isaac Newton

From the same principles, I now demonstrate the frame of the System of the World. ~ Isaac Newton

Descartes gave sight to the blind. These saw the errors of antiquity and of the sciences. The path he struck out is since become boundless [ ... ] In fathoming this abyss no bottom has been found. We are now to examine what discoveries Sir Isaac Newton has made in it. ~ Voltaire

I do not define time, space, place, and motion, as being well known to all. Only I must observe, that the common people conceive those quantities under no other notions but from the relation they bear to sensible objects. And thence arise certain prejudices, for the removing of which it will be convenient to distinguish them into absolute and relative, true and apparent, mathematical and common. ~ Isaac Newton

The best way to understanding is a few good examples. ~ Isaac Newton

Bullialdus wrote that all force respecting ye Sun as its center & depending on matter must be reciprocally in a duplicate ratio of ye distance from ye center. ~ Isaac Newton

Is not Fire a Body heated so hot as to emit Light copiously? For what else is a red hot Iron than Fire? And what else is a burning Coal than red hot Wood? ~ Isaac Newton

This principle of nature being very remote from the conceptions of Philosophers, I forbore to describe it in that book, least I should be accounted an extravagant freak and so prejudice my Readers against all those things which were the main designe of the book. ~ Isaac Newton

Where both are friends, it is right to prefer truth. ~ Isaac Newton

Great scientific minds, from Claudius Ptolemy of the second century to Isaac Newton of the seventeenth, invested their formidable intellects in attempts to deduce the nature of the universe from the statements and philosophies contained in religious writings ... Had any of these efforts worked, science and religion today might be one and the same. But they are not. ~ Neil DeGrasse Tyson

The description of right lines and circles, upon which geometry is founded, belongs to mechanics. Geometry does not teach us to draw these lines, but requires them to be drawn. ~ Isaac Newton

By such deductions the law of gravitation is rendered probable, that every particle attracts every other particle with a force which varies inversely as the square of the distance. The law thus suggested is assumed to be universally true. ~ Isaac Newton

A Vulgar Mechanick can practice what he has been taught or seen done, but if he is in an error he knows not how to find it out and correct it, and if you put him out of his road he is at a stand. Whereas he that is able to reason nimbly and judiciously about figure, force, and motion, is never at rest till he gets over every rub.
(from a letter dated 25 May, 1694) ~ Isaac Newton

Sir Isaac Newton said, "If I have seen further, it is by standing on the
shoulders of giants." Smart guys like Isaac know that there is much to
be learned from those who came before us. Be like Isaac. ~ Chad Fowler

I can measure the motion of bodies but I cannot measure human folly. ~ Isaac Newton

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. ~ Isaac Newton

The most famous story about gravity involves Isaac Newton and an apple that supposedly fell on his head, inspiring him to concoct his theory of universal gravitation. (It's mostly famous because Newton himself couldn't stop telling it later in life, in an unnecessary attempt to add some extra juice to his reputation as a genius.) ~ Sean Carroll

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. ~ Isaac Newton

Newton was an unquestioning believer in an all-wise creator of the universe, and in his own inability - like the boy on the seashore - to fathom the entire ocean in all its depths. He therefore believed that there were not only many things in heaven beyond his philosophy, but plenty on earth as well, and he made it his business to understand for himself what the majority of intelligent men of his time accepted without dispute (to them it was as natural as common sense) - the traditional account of the creation. ~ Isaac Newton

The alternation of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. ~ Isaac Newton

I know not how I seem to others, but to myself I am but a small child wandering upon the vast shores of knowledge, every now and then finding a small bright pebble to content myself with while the vast ocean of undiscovered truth lay before me. ~ Isaac Newton

Newtonian physics runs into problems at the subatomic level. Down there--in the land of hadrons, quarks, and Schrödinger's cat--things gent freaky. The cool rationality of Isaac Newton gives way to the bizarre unpredictability of Lewis Carroll. ~ Daniel H. Pink

"We hold these truths to be sacred and undeniable" in a draft of the Declaration of Independence changes it instead into an assertion of rationality. The scientific mind of Franklin drew on the scientific determinism of Isaac Newton and the analytic empiricism of David Hume and Gottfried Leibniz. In what became known as "Hume's Fork" the latters' theory distinguished between synthetic truths that describe matters of fact, and analytic truths that are self-evident by virtue of reason and definition. ~ Benjamin Franklin

They who search after the Philosopher's Stone [are] by their own rules obliged to a strict and religious life. ~ Isaac Newton

I believe in logic, the sequence of cause and effect, and in science its only begotten son our law, which was conceived by the ancient Greeks, thrived under Isaac Newton, suffered under Albert Einstein ...
That fragment of a 'creed for materialism' which a friend in college had once shown him rose through Donald's confused mind. ~ John The Apostle

For the birth of something new, there has to be a happening. Newton saw an apple fall; James Watt watched a kettle boil; Rontgen fogged some photographic plates. And these people knew enough to translate ordinary happenings into something new ... ~ Alexander Fleming

The same law takes place in a system, consisting of many bodies, as in one single body, with regard to their persevering in their state of motion or of rest. For the progressive motion, whether of one single body or of a whole system of bodies, is always to be estimated from the motion of the center of gravity. ~ Isaac Newton

A good watch may serve to keep a recconing at Sea for some days and to know the time of a Celestial Observ[at]ion: and for this end a good Jewel watch may suffice till a better sort of Watch can be found out. But when the Longitude at sea is once lost, it cannot be found again by any watch. ~ Isaac Newton

It is not therefore the business of philosophy, in our present situation in the universe, to attempt to take in at once, in one view, the whole scheme of nature; but to extend, with great care and circumspection, our knowledge, by just steps, from sensible things, as far as our observations or reasonings from them will carry us, in our enquiries concerning either the greater motions and operations of nature, or her more subtile and hidden works. In this way Sir Isaac Newton proceeded in his discoveries. ~ Colin Maclaurin

For the purposes of science, information had to mean something special. Three centuries earlier, the new discipline of physics could not proceed until Isaac Newton appropriated words that were ancient and vague - force, mass, motion, and even time - and gave them new meanings. Newton made these terms into quantities, suitable for use in mathematical formulas. Until then, motion (for example) had been just as soft and inclusive a term as information. For Aristotelians, motion covered a far-flung family of phenomena: a peach ripening, a stone falling, a child growing, a body decaying. That was too rich. Most varieties of motion had to be tossed out before Newton's laws could apply and the Scientific Revolution could succeed. In the nineteenth century, energy began to undergo a similar transformation: natural philosophers adapted a word meaning vigor or intensity. They mathematicized it, giving energy its fundamental place in the physicists' view of nature.

It was the same with information. A rite of purification became necessary.

And then, when it was made simple, distilled, counted in bits, information was found to be everywhere. ~ James Gleick

The split between religion and science is relatively new. Isaac Newton, who first worked out the laws by which gravity held the planets and even the stars in their traces, was sufficiently impressed by the scale and regularity of the universe to ascribe it all to God. ~ Seth Shostak

You ask me how, with so much study, I manage to retene my health ... Morpheous is my last companion ; without 8 or 9 hours of him yr correspondent is not worth one scavenger's peruke. My practices did at ye first hurt my stomach, but now I eat heartily enou' as y' will see when I come down beside you. [On the value of sleep, and harm of eating poorly while intent on study.] ~ Isaac Newton

I have presented principles of philosophy that are not, however, philosophical but strictly mathematical-that is, those on which the study of philosophy can be based. These principles are the laws and conditions of motions and of forces, which especially relate to philosophy. ~ Isaac Newton

He rules all things, not as the world soul but as the lord of all. And because of his dominion he is called Lord God Pantokrator. For 'god' is a relative word and has reference to servants, and godhood is the lordship of God, not over his own body as is supposed by those for whom God i the world soul, but over servants. The supreme God is an eternal, infinite, and absolutely perfect being; but a being, however perfect, without dominion is not the Lord God. ~ Isaac Newton

If my name were Isaac Newton, would I be a famous no name? I'd have worldwide and historical name recognition, yet I'd be anonymous. ~ Jarod Kintz

God made and governs the world invisibly, and has commanded us to love and worship him and no other God; to honor our parents and masters, and love our neighbours as ourselves; and to be temperate, just, and peaceable, and to be merciful even to brute beasts. ~ Isaac Newton

Daniel was in the greatest credit amongst the Jews, till the reign of the Roman Emperor Hadrian . And to reject his prophecies, is to reject the Christian religion. For this religion is founded upon his prophecy concerning the Messiah . ~ Isaac Newton

Truth is ever to be found in simplicity and not in the multiplicity and confusion of things.
Sir Isaac Newton

Imagination is more important than knowledge.For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution.
Albert Einstein ~ Sir Isaac Newton Albert Einstein

In scripture we are told of some trusting in God and others trusting in idols, and that God is our refuge, our strength, our defense. In this sense God is the rock of his people, and false Gods are called the rock of those that trust in them, Deut. xxxii. 4, 15, 18, 30, 31, 37. In the same sense the Gods of the King who shall do according to his will are called Mahuzzims, munitions, fortresses, protectors, guardians, or defenders. ~ Isaac Newton

If I have done the public any service, it is due to my patient thought. ~ Isaac Newton

The daily disappearance and the subsequent rise of the sun appeared to many of the ancients as a true resurrection; thus, while the east came to be regarded as the source of light and warmth, happiness and glory, the west was associated with darkness and chill, decay and death. This led to the custom of burying the dead so as to face the east when they rose again, and of building temples and shrines with an opening toward the east. To effect this, Vitruvius, two thousand years ago, gave precise rules, which are still followed by Christian architects. ~ Isaac Newton

Sir Isaac Newton is said to have avowed that he felt like a child picking up shells beside the great and unexplored ocean of truth. ~ Mary Shelley

Since her death in 1979, the woman who discovered what the universe is made of has not so much as received a memorial plaque. Her newspaper obituaries do not mention her greatest discovery. […] Every high school student knows that Isaac Newton discovered gravity, that Charles Darwin discovered evolution, and that Albert Einstein discovered the relativity of time. But when it comes to the composition of our universe, the textbooks simply say that the most abundant atom in the universe is hydrogen. And no one ever wonders how we know. ~ Jeremy Knowles

If the ancient churches, in debating and deciding the greatest mysteries of religion, knew nothing of these two texts, I understand not why we should be so fond of them now the debate is over. ~ Isaac Newton

An object that is at rest will tend to stay at rest. An object that is in motion will tend to stay in motion. ~ Isaac Newton

Do not several sorts of Rays make Vibrations of several bignesses, which according to their bigness excite Sensations of several Colours, much after the manner that the Vibrations of the Air, according to their several bignesses excite Sensations of several Sounds? And particularly do not the most refrangible Rays excite the shortest Vibrations for making a Sensation of deep violet, the least refrangible the largest form making a Sensation of deep red, and several intermediate sorts of Rays, Vibrations of several intermediate bignesses to make Sensations of several intemediate Colours? ~ Isaac Newton

Are not all Hypotheses erroneous, in which Light is supposed to consist in Pression or Motion, propagated through a fluid Medium? For in all these Hypotheses the Phaenomena of Light have been hitherto explain'd by supposing that they arise from new Modifications of the Rays; which is an erroneous Supposition. ~ Isaac Newton

In the absence of any other proof, the thumb alone would convince me of God's existence. ~ Isaac Newton

When Isaac Newton embarked on his great program, he encountered a fundamental lack of definition where it was most needed. He began with a semantic sleight of hand: "I do not define time, space, place, and motion, as being well known to all," he wrote deceptively. Defining these words was his very purpose. There were no agreed standards for weights and measures. Weight and measure were themselves vague terms. Latin seemed more reliable than English, precisely because it was less worn by everyday use, but the Romans had not possessed the necessary words either. ~ James Gleick

The Church no more gave us the New Testament canon than Isaac Newton gave us the force of gravity. ~ J.I. Packer

Atheism is so senseless & odious to mankind that it never had many professors. Can it be by accident that all birds beasts & men have their right side & left side alike shaped (except in their bowels) & just two eyes & no more on either side the face & just two ears on either side the head & a nose with two holes & no more between the eyes & one mouth under the nose & either two fore legs or two wings or two arms on the shoulders & two legs on the hips one on either side & no more? ~ Isaac Newton

The suspect nature of these stories can be seen in the anecdote Jefferson told of Hamilton visiting his lodging in 1792 and inquiring about three portraits on the wall. "They are my trinity of the three greatest men the world has ever produced," Jefferson replied: "Sir Francis Bacon, Sir Isaac Newton, and John Locke." Hamilton supposedly replied, "The greatest man that ever lived was Julius Casar. ~ Ron Chernow

So great a contribution to physics was Two New Sciences that scholars have long maintained that the book anticipated Isaac Newton's laws of motion. ~ Stephen Hawking

All our names are just stupid nicknames they made up - like Alby for Albert Einstein, Newt for Isaac Newton, and me - Thomas. As in Edison. ~ Anonymous

The best and safest method of philosophizing seems to be first to inquire diligently into the properties of things, and establishing those properties by experiments, and then to proceed more slowly to hypotheses for the explanation of them. ~ Isaac Newton

If I had seen further than others, it's because I stood upon the shoulders of giants. ~ Isaac Newton

The seed of a tree has the nature of a branch or twig or bud. It is a part of the tree, but if separated and set in the earth to be better nourished, the embryo or young tree contained in it takes root and grows into a new tree. ~ Isaac Newton

Now the smallest Particles of Matter may cohere by the strongest Attractions, and compose bigger Particles of weaker Virture ... There are therefore Agents in Nature able to make the Particles of Bodies stick together by very strong Attraction. And it is the Business of experimental Philosophy to find them out. ~ Isaac Newton

I esteem his understanding and subtlety highly, but I consider that they have been put to ill use in the greater part of his work, where the author studies things of little use...

{Writing about Isaac Newton} ~ Christiaan Huygens

Here, reader, thou must pardon us if we stop a while to lament the capriciousness of Nature in forming this charming part of the creation designed to complete the happiness of man; with their soft innocence to allay his ferocity, with their sprightliness to soothe his cares, and with their constant friendship to relieve all the troubles and disappointments which can happen to him. Seeing then that these are the blessings chiefly sought after and generally found in every wife, how must we lament that disposition in these lovely creatures which leads them to prefer in their favour those individuals of the other sex who do not seem intended by nature as so great a masterpiece! For surely, however useful they may be in the creation, as we are taught that nothing, not even a louse, is made in vain, yet these beaus, even that most splendid and honoured part which in this our island nature loves to distinguish in red, are not, as some think, the noblest work of the Creator. For my own part, let any man chuse to himself two beaus, let them be captains or colonels, as well-dressed men as ever lived, I would venture to oppose a single Sir Isaac Newton, a Shakespear, a Milton, or perhaps some few others, to both these beaus; nay, and I very much doubt whether it had not been better for the world in general that neither of these beaus had ever been born than that it should have wanted the benefit arising to it from the labour of any one of those persons.

If this be true, how m ~ Henry Fielding

The one as much as it advances that of the other. If a body impinge upon another, and by its force change the motion of the other, that body also (because of the equality of the mutual pressure) will undergo an equal change, in its own motion, towards the contrary part. ~ Isaac Newton

Why there is one body in our System qualified to give light and heat to all the rest, I know no reason but because the Author of the System thought it convenient; and why there is but one body of this kind, I know no reason, but because one was sufficient to warm and enlighten all the rest. ~ Isaac Newton

Could we have entered into the mind of Sir Isaac Newton, and have traced all the steps by which he produced his great works, we might see nothing very extraordinary in the process. ~ Joseph Priestley

Always preoccupied with his profound researches, the great Newton showed in the ordinary-affairs of life an absence of mind which has become proverbial. It is related that one day, wishing to find the number of seconds necessary for the boiling of an egg, he perceived, after waiting a minute, that he held the egg in his hand, and had placed his seconds watch (an instrument of great value on account of its mathematical precision) to boil!
This absence of mind reminds one of the mathematician Ampere, who one day, as he was going to his course of lectures, noticed a little pebble on the road; he picked it up, and examined with admiration the mottled veins. All at once the lecture which he ought to be attending to returned to his mind; he drew out his watch; perceiving that the hour approached, he hastily doubled his pace, carefully placed the pebble in his pocket, and threw his watch over the parapet of the Pont des Arts. ~ Camille Flammarion

Yet one thing secures us what ever betide, the scriptures assures us that the Lord will provide. ~ Isaac Newton

As in Mathematicks, so in Natural Philosophy, the Investigation of difficult Things by the Method of Analysis, ought ever to precede the Method of Composition. This Analysis consists in making Experiments and Observations, and in drawing general Conclusions from them by Induction, and admitting of no Objections against the Conclusions, but such as are taken from Experiments, or other certain Truths. For Hypotheses are not to be regarded in experimental Philosophy. ~ Isaac Newton

I just think it's fortunate that Sir Isaac Newton didn't share the sense of humor of a member of the public, because had he done so, he would of been so amused by the simple effects of gravity, that he would of never gotten round making a comprehensive study of it's causes.
That's the punchline! 'a comprehensive study of it's courses'! I worked for that! Will you be telling this joke at work? I don't think so!
And yes, I am aware that I say this to you while hanging precariously of this art-deco balcony. And I do so deliberately in the hope that I will fall to my death, and that you will learn about the thin line between slap-stick and tragedy. ~ Stewart Lee

If the experiments which I urge be defective, it cannot be difficult to show the defects; but if valid, then by proving the theory, they must render all objections invalid. ~ Isaac Newton

The usual consolations of life, friendship and sex included, appealed to Newton hardly at all. Art, literature, and music had scarcely more allure. He dismissed the classical sculptures in the Earl of Pembroke's renowned collection as "stone dolls." He waved poetry aside as "a kind of ingenious nonsense." He rejected opera after a single encounter. "The first Act I heard with pleasure, the 2d stretch'd my patience, at the 3d I ran away. ~ Edward Dolnick

Perhaps the most important contribution to science that the Royal Society has made in its three centuries of existence is its early role in publishing Newton's masterful account of his discoveries. ~ Julian Schwinger

The centre of the system of the world is immovable. ~ Isaac Newton

Alfred Hitchcock, Isaac Newton, Elvis Presley, Captain Bligh, they're heroic or pathetic depending on which book you buy. ~ Bob Seger

Fidelity and allegiance sworn to the King is only such a fidelity and obedience as is due to him by the law of the land; for were that faith and allegiance more than what the law requires, we would swear ourselves slaves and the King absolute; whereas, by the law, we are free men, notwithstanding those oaths. ~ Isaac Newton

Pictures, propagated by motion along the fibers of the optic nerves in the brain, are the cause of vision. ~ Isaac Newton

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. ~ Isaac Newton

Definition of inertia: 'The vis insita, or innate force of matter, is a power of resisting by which every body, as much as in it lies, endeavours to preserve its present state, whether it be of rest or of moving uniformly forward in a straight line. ~ Isaac Newton

The monarchy of the Greeks for want of an heir was broken into several kingdoms; four of which, seated to the four winds of heaven, were very eminent. For Ptolemy reigned over Egypt, Lybia and Ethiopia ; Antigonus over Syria and the lesser Asia; Lysimachus over Thrace ; and Cassander over Macedon, Greece and Epirus . ~ Isaac Newton

Notwithstanding all that has been discovered since Newton's time, his saying that we are little children picking up pretty pebbles on the beach while the whole ocean lies before us unexplored remains substantially as true as ever, and will do so though we shovel up the pebbles by steam shovels and carry them off in carloads. ~ Charles Sanders Peirce

If you are affronted it is better to pass it by in silence, or with a jest, though with some dishonor, than to endeavor revenge. If you can keep reason above passion, that and watchfulness will be your best defenders. ~ Isaac Newton
