SHIRLEY GRIFFITH:Much of today's science of physics is based on Newton's discovery of the three laws of motion and his theory of gravity. Newton also developed one of the most powerful tools of mathematics. It is the method we call calculus.
Late in his life, Newton said of his work: "If I saw further than other men, it was because I stood on the shoulders of giants. "
STEVE EMBER: One of those giants was the great Italian scientist, Galileo. Galileo died the same year Newton was born. Another of the giants was the Polish scientist Nicholas Copernicus. He lived a hundred years before Newton.
Copernicus had begun a scientific revolution. It led to a completely new understanding of how the universe worked. Galileo continued and expanded the work of Copernicus.
Isaac Newton built on the ideas of these two scientists and others. He found and proved the answers for which they searched.
