He did many calculations and discovered gravity. Sir Isaac NewtonSIR Isaac Newton was famous for being the first person to lay down the laws on gravity and force. He is the person who was said to be sitting under an apple tree and an apple fell on his head. He also figured out why a rainbow is made.Isaac Newton was well known the three laws of motion. He was also know for the math genius he was. sir Isaac Newton was famous for many things, but his moat famous were the 3 laws of motion, explaining gravity, and the light spectrum.e also figured out why a rainbow is made.
