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 sea-shore, 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. Isaac Newton

If I have seen further it is by standing on the shoulders of giants. Isaac Newton
No great discovery was ever made without a bold guess. Isaac Newton
