Isaac Newton

To myself I am only a child playing on the beach, while vast oceans of truth lie undiscovered before me.

Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it.

If I have ever made any valuable discoveries, it has been owing more to patient attention, than to any other talent.

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

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

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

Tact is the knack of making a point without making an enemy.

To every action there is always opposed an equal reaction.

I can calculate the motion of heavenly bodies, but not the madness of people.
