Isaac Newton

"I do not know what I may appear to the world but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me. "

"I keep the subject of my inquiry constantly before me, and wait till the first dawning opens gradually, by little and little, into a full and clear light. "

"I seem to have been like a child playing on the sea shore, finding now and then a prettier shell than ordinary, whilst the great ocean of truth lay undiscovered before me. "

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

"If I have seen further it is by standing on the shoulders of giants. "

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