Isaac+Newton

1. What were the contributions of these scientists? He is known most for his theory of universal gravitation, which became the basis for many subsequent scientific astronomical studies. 2. What experiment did they perform (briefly outline)? The experimentum crucis, in a dark room Newton allowed a narrow beam of sunlight to pass from a small hole in a window shutter through a prism, which made a rainbow and then put another prism in front of that which made the white light. 3. Did they experiment because of an accidental discovery (accidentally stumbled upon something and then experimented further) or did they discover something accidentally through work on something else? He saw a apple fall from a tree and wondered why it happened. 4. Did their contribution lead to a theory or a law? State name of the theory or law. Laws of Motion and Laws of Gravity.
