Sir Isaac Newton's three laws of motion describe the motion of massive
bodies and how they interact. While Newton's laws may seem obvious to us
today, more than three centuries ago they were considered revolutionary.
Newton was one of the most influential scientists of all time. His ideas
became the basis for modern physics. He built upon ideas put forth from the
works of previous scientists including Galileo and Aristotle and was able to
prove some ideas that had only been theories in the past. He studied optics,
astronomy and math — he invented calculus. (German mathematician
Gottfried Leibniz is also credited with developing it independently at about
the same time.)
