Differential calculus, discovery

Gottfried Wilhelm Leibniz, 1646-1716 German mathematician, philosopher, historian, and scientist. Independent discoverer of the differential calculus He was personally acquainted widi Brand and Krafft, and wrote a detailed account of the discovery of phosphorus, including biographical sketches of Brand, Krafft, Kunckel, and Becher. 

Sir Isaac Newton, one of the giants of science. You probably know of him from his theory of gravitation. In addition, he made enormous contributions to the understanding of many other aspects of physics, including the nature and behavior of hght, optics, and the laws of motion. He is credited with the discoveries of differential calculus and of expansions into infinite series. 

The genesis of this discovery called for a series of curious coincidences. The absolute differential calculus was a speciality only of the School of Zurich, and it required an improbable meeting between this School, Albert Einstein and the mathematician Marcel Grossmann, who was also able to think as a pure physicist.
