Thomas Edison Thomas Alva Edison  (February 11, 1847 – October 18, 1931) was an American inventor and businessman who has been described as America's greatest inventor. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures.These inventions, which include the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb, have had a widespread impact on the modern industrialized world.He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest; early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He lat

Sir Isaac Newton   (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, theologian, and author (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia  Mathematica  ( Mathematical Principles of Natural Philosophy ), first published in 1687, laid the foundations of classical mechanics. Newton also made seminal contributions to optics, and shares credit with Gottfried Wilhelm Leibniz for developing the infinitesimal calculus. In  Principia , Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to prove Kepler's laws of planetary motion, account for tides, the trajectories of comets, the precession of t

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the idea of relativity, one in every of the 2 pillars of recent physics (alongside quantum mechanic) His work is additionally known for its influence on the philosophy of science. he's best known to the overall public for his principle formula E = mc2, which has been dubbed "the world's most famous equation". He received the 1921 honor in Physics "for his services to theoretical physics, and particularly for his discovery of the law of the photoelectric effect", a pivotal step within the development of scientific theory. The son of a salesman who later operated an electrochemical factory, Einstein was born within the German Empire but moved to Switzerland in 1895 and renounced his German citizenship in 1896. Specializing in physics and arithmetic, he received his academic teaching diploma from nation Federal Polytechnic School in Zürich in 1900.
