In 1672, Newton became a member of the Royal Society a group of scientists committed to the experimental method. He presented one of his new telescopes to the Royal Society along with his findings on light. The Royal Society set up a committee led by physicist Robert Hooke to evaluate Newtons findings. Hooke was a scientist employed by the Royal Society to evaluate new inventions. However, Hooke had his own ideas on light and was slow to accept the truth of Newtons findings. This surprised and disappointed Newton, who even considered not circulating his discoveries in the future.While it is sometimes said that Newton was too sensitive to critical evaluation of his work, he was merely concerned that the time spent justifying past findings was preventing him from making new discoveries.
