Biography of Sir Isaac Newton

Isaac Newton's life can be divided into three different periods. The first was childhood when appointed Chairman from 1643 to 1669. The second period was from 1669 to 1687, when his professor was born at the University of Cambridge. In the third period (almost the same period as the other two periods), I saw that Newton was a senior government official with a high salary in London and had little interest in mathematical research. Isaac Newton was born at Woolthorpe Estate near Grantham, Lincolnshire.

In 1726, Newton shared this anecdote with William Stukeley and put it in the biography of "Sir Isaac Newton's Biography" published in 1752. According to Stukeley, "After dinner the weather was warm, we entered the garden and drank them in the shadows of some apple trees, he said I was in the same position as before. That concept came into my mind ... When the apple fell down, he sat down in a meditative way. "

Sir Isaac Newton stood in the shade of an apple and saw an apple falling on the ground. "Why does the apple always fall perpendicular to the ground?" Newton thought. "Why is it not always horizontal or upward, should I always face the center of the earth? To be precise, the reason is that the earth attracts it, it must be virtually attractive." In ten years he studied his view on gravity, and in 1687 he published his innovative work. A falling apple is just a series of decades of ideas.

I quoted a biography of Peter Akroid's new biography, Isaac Newton. He did not discover his consciousness about the influence of the gravity of the fall of the apple, as in the legend. He is more detailed than his study like Mrs. Curie, and he is not afraid to experiment. He is enthusiastic about distinguishing light from color and finding out the result of seeing one eye from the sun. In the process, he had to spend three days in a dark room to ignore his vision and recover from his experience. Later, in order to test the Cartesian theory that light passes the pressure of ether as "pressure", he slid a large needle as close as possible between my eyes and bone. "With a dedicated obsession, he tried to change his retinal curve so that he could observe the result even if it took the risk of blurring his eyes.
