Michelson-
Maxwell was a great British physicist and mathematician in the19th century. Maxwell is mainly engaged in electromagnetic theory, molecular physics, statistical physics, optics, mechanics and elasticity theory. In particular, his electromagnetic field theory, which unifies electricity, magnetism and light, is the most brilliant achievement of the development of physics in the19th century and one of the greatest complexes in the history of science.
Kepler-German astronomer. It was found that the planets move in elliptical orbits, and three laws of planetary motion (Kepler's law) were put forward, which laid the foundation for Newton to discover the law of universal gravitation.
Lorenz, a Dutch physicist and mathematician, was born in Anam. Graduated from Leiden University, Ph.D. 65438 to 0875. Lorenz is the founder of classical electronic theory.
Lengz-Russian physicist and geophysicist, mainly engaged in electrical research. Lenz's law holds.
Joule-Joule, an outstanding British physicist. Joule has been engaged in experimental research all his life and made outstanding contributions to electromagnetism, heat and gas molecular dynamics theory.
Hertz, a German physicist, was born in Hamburg. Hertz's greatest contribution to mankind is to prove the existence of electromagnetic waves by experiments.
Huygens-Dutch physicist, mathematician and astronomer.
Galileo was a famous Italian mathematician, astronomer, physicist and philosopher, and he was the first scientific giant to integrate mathematics, astronomy and physics on the basis of scientific experiments. Galileo was a pioneer of the scientific revolution. He spent his whole life proving and widely publicizing the new world outlook initiated by Copernicus and Kepler.
Gauss, a German mathematician and physicist, 1777 was born in Brunswick, Germany on April 30th. Gauss has been engaged in mathematics for a long time, and applied mathematics to physics, astronomy and geodesy, with rich writings and many achievements.
Faraday-British physicist, chemist and famous self-taught scientist. Faraday is mainly engaged in the research of electricity, magnetism, magneto-optic and electrochemistry, and has made a series of important discoveries in these fields. He is the founder of electromagnetic field theory.
Einstein-German physicist, 192 1 Nobel Prize winner in physics. His scientific achievements mainly include four aspects: early research on Brownian motion; The establishment of special relativity; Promote the development of quantum mechanics; The establishment of the general theory of relativity has opened up a way to study cosmology.
Descartes-,1596 16 On March 3rd, in Toulon, Scilletta Peninsula in western France, Descartes first realized that the law of inertia was the key to solving mechanical problems and established it as a principle.
Coulomb-French engineer and physicist.
Brewster-Scottish physicist, mainly engaged in optical research.
Bell, the inventor of the telephone, was born in Edinburgh, Scotland on 1847.
