Today is Sir Isaac Newton’s bithday. I was looking up at the Moon tonight and trying to see what he might have seen.

He wrote, “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.”
