Sir Isaac Newton
(25 Dec 1642 - 20 Mar 1727)

English physicist and mathematician who made seminal discoveries in several areas of science, and was the leading scientist of his era.



Qu. 31. Have not the small Particles of Bodies certain Powers, Virtues or Forces, by which they act at a distance, not only upon the Rays of Light for reflecting, refracting and reflecting them, but also upon one another for producing a great part of the Phænomena of Nature?
— Sir Isaac Newton
From Opticks, (1704, 2nd ed. 1718), Book 3, Query 31, 350.
Science quotes on:  |  Act (272)  |  Body (537)  |  Certain (550)  |  Distance (163)  |  Force (488)  |  Great (1575)  |  Light (609)  |  Nature (1928)  |  Particle (196)  |  Phenomenon (319)  |  Power (747)  |  Ray (114)  |  Reflecting (3)  |  Small (479)  |  Virtue (109)

All material Things seem to have been composed of the hard and solid Particles … variously associated with the first Creation by the Counsel of an intelligent Agent. For it became him who created them to set them in order: and if he did so, it is 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.
— Sir Isaac Newton
From Opticks (1704, 2nd ed., 1718), 377-378.
Science quotes on:  |  Agent (70)  |  All (4107)  |  Arise (158)  |  Associated (2)  |  Big Bang (40)  |  Chaos (91)  |  Composed (3)  |  Counsel (11)  |  Creation (329)  |  First (1284)  |  Hard (243)  |  Intelligent (100)  |  Law (895)  |  Material (353)  |  Mere (84)  |  Nature (1928)  |  Order (632)  |  Origin (241)  |  Origin Of Earth (9)  |  Origin Of The Universe (19)  |  Other (2236)  |  Particle (196)  |  Pretend (17)  |  Seek (213)  |  Set (394)  |  Solid (116)  |  Thing (1915)  |  World (1778)

And thus Nature will be very conformable to her self and very simple, performing all the great Motions of the heavenly Bodies by the Attraction of Gravity which intercedes those Bodies, and almost all the small ones of their Particles by some other attractive and repelling Powers which intercede the Particles. The Vis inertiae is a passive Principle by which Bodies persist in their Motion or Rest, receive Motion in proportion to the Force impressing it, and resist as much as they are resisted. By this Principle alone there never could have been any Motion in the World. Some other Principle was necessary for putting Bodies into Motion; and now they are in Motion, some other Principle is necessary for conserving the Motion.
— Sir Isaac Newton
From Opticks, (1704, 2nd ed. 1718), Book 3, Query 31, 372-3.
Science quotes on:  |  All (4107)  |  Alone (312)  |  Attraction (56)  |  Attractive (24)  |  Conservation (168)  |  Force (488)  |  Gravity (133)  |  Great (1575)  |  Law Of Motion (14)  |  Motion (312)  |  Nature (1928)  |  Necessary (363)  |  Never (1087)  |  Other (2236)  |  Particle (196)  |  Power (747)  |  Principle (510)  |  Proportion (136)  |  Receive (114)  |  Rest (281)  |  Self (267)  |  Simple (406)  |  Small (479)  |  Will (2354)  |  World (1778)

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.
— Sir Isaac Newton
In Isaac Newton and Percival Frost (ed.) Newton's Principia: Sections I, II, III (1863), 217.
Science quotes on:  |  Attraction (56)  |  Deduction (82)  |  Distance (163)  |  Force (488)  |  Gravitation (71)  |  Inverse Square Law (4)  |  Law (895)  |  Law Of Gravitation (22)  |  Other (2236)  |  Particle (196)  |  Render (93)  |  Square (70)  |  Universal (189)

It seems probable to me that God, in the beginning, formed matter in solid, massy, hard, impenetrable, moveable particles, of such sizes and figures, and with such other properties, and in such proportions to space, as most conduced to the end for which He formed them; and that these primitive particles, being solids, are incomparably harder than any porous bodies compounded of them, even so very hard as never to wear or break in pieces; no ordinary power being able to divide what God had made one in the first creation.
— Sir Isaac Newton
From Opticks (1704, 2nd ed., 1718), 375-376.
Science quotes on:  |  Atom (358)  |  Beginning (305)  |  Being (1278)  |  Break (99)  |  Compound (113)  |  Creation (329)  |  Divide (76)  |  End (590)  |  Figure (160)  |  First (1284)  |  Form (960)  |  God (758)  |  Hard (243)  |  Matter (801)  |  Most (1729)  |  Never (1087)  |  Ordinary (160)  |  Other (2236)  |  Particle (196)  |  Power (747)  |  Primitive (75)  |  Proportion (136)  |  Solid (116)  |  Space (501)

It seems to me farther, that these Particles have not only a Vis inertiae, accompanied with such passive Laws of Motion as naturally result from that Force, but also that they are moved by certain active Principles, such as that of Gravity, and that which causes Fermentation, and the Cohesion of Bodies. These Principles I consider, not as occult Qualities, supposed to result from the specifick Forms of Things, but as general Laws of Nature, by which the Things themselves are form'd; their Truth appearing to us by Phaenomena, though their Causes be not yet discover'd. For these are manifest Qualities, and their Causes only are occult.
— Sir Isaac Newton
From Opticks, (1704, 2nd ed. 1718), Book 3, Query 31, 376-377.
Science quotes on:  |  Active (76)  |  Cause (542)  |  Certain (550)  |  Cohesion (7)  |  Consider (416)  |  Discover (553)  |  Farther (51)  |  Fermentation (15)  |  Force (488)  |  Form (960)  |  General (511)  |  Gravity (133)  |  Law (895)  |  Law Of Motion (14)  |  Law Of Nature (73)  |  Laws Of Motion (10)  |  Motion (312)  |  Nature (1928)  |  Occult (8)  |  Particle (196)  |  Principle (510)  |  Result (678)  |  Themselves (433)  |  Thing (1915)  |  Truth (1062)

Thus far I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity. Indeed, this force arises from some cause that penetrates as far as the centers of the sun and planets without any diminution of its power to act, and that acts not in proportion to the quantity of the surfaces of the particles on which it acts (as mechanical causes are wont to do) but in proportion to the quantity of solid matter, and whose action is extended everywhere to immense distances, always decreasing as the squares of the distances.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
