In mechanics, Newton formulated the principles of conservation of momentum and angular
momentum. In optics, he invented the reflecting telescope and developed a theory of colour
based on the observation that a prism decomposes white light into a visible spectrum. He also
formulated an empirical law of cooling and studied the speed of sound.
In mathematics, Newton shares the credit with Gottfried Leibnitz for the development of the
differential and integral calculus.
In a 2005 poll of the Royal Society asking who had the greater effect on the history of science,
Newton was deemed much more influential than Albert Einstein.
