N2  - "Physics was born of Isaac Newton's thoughts on gravity, from his legendary apple to the stone whirled on a string that helped him gauge the force that keeps the moon in orbit. Albert Einstein launched the next great wave of thinking about gravity when he posited that a falling man could not feel his own weight-the basis of his 'equivalence principle.' The author outlines the conception of the universe that followed from Einstein's insight."
