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




An object in motion tends to remain in motion along a straight line unless acted upon by an outside force.Isaac Newton

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

The Ignis Fatuus is a vapor shining without heat.Isaac Newton

This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being.Isaac Newton

Gravity may put the planets into motion, but without the divine Power, it could never put them into such a circulating motion as they have about the Sun; and therefore, for this as well as other reasons, I am compelled to ascribe the frame of this System to an intelligent Agent.Isaac Newton

The same thing is to be understood of all bodies, revolved in any orbits. They all endeavour to recede from the centres of their orbits, and were it not for the opposition of a contrary force which restrains them to and detains them in their orbits, which I therefore call Centripetal, would fly off in right lines with a uniform motion.Isaac Newton

Gravity must be caused by an Agent acting constantly according to certain laws, but whether this Agent be material or immaterial I have left to the consideration of my readers.Isaac Newton

That the divided but contiguous particles of bodies may be separated from one another is a matter of observation; and, in the particles that remain undivided, our minds are able to distinguish yet lesser parts, as is mathematically demonstrated.Isaac Newton

Absolute space, in its own nature, without regard to anything external, remains always similar and immovable.
