Jonas salk, who invented inactivated polio vaccine to eradicate polio, one of the most terrible plagues in the world.

Samuel Morse, Morse code was the fastest way to contact before human beings entered the Internet age.

Robert Oppenheimer, the chief scientist of Manhattan Project, is known as the "father of the atomic bomb" of mankind, a professor at the University of California, Berkeley, and later the chairman and general counsel of the American Atomic Energy Commission (1947 ~ 1952), and the president of the Institute of Advanced Studies in Princeton, USA. He deeply regretted that he had become a midwife in the era of thermonuclear weapons, and was ordered to disarm and return to the battlefield because he opposed the US government's trial-production of hydrogen bombs.

Louis sullivan, the father of skyscrapers.

1 1 william james, American philosopher and psychologist, pragmatist, founder of functional psychology, is known as "the father of American psychology".

12 james dewey watson, a famous biologist, discovered the double helix molecular structure of deoxyribonucleic acid (DNA), thus revealing the code of life. 1962 shared the Nobel Prize in Physiology or Medicine with Britain's francis crick and maurice wilkins.

13 betty friedan, a spokeswoman for the feminist movement in the 1960s, described the grievances and resentments of housewives, which greatly promoted the "second sex" revolution under male chauvinism.

14 Enrico Fermi, an Italian-born American scientist, won the Nobel Prize in Physics in 1938 and went to the United States in 1939. He was an important figure in the Manhattan Project and was known as the "father of atomic energy" of mankind. 1942, he presided over the establishment of the world's first nuclear reactor-Chicago I.

15 Fleming, who happened to find that the secretion of penicillin could kill staphylococcus during experimental observation. Since then, human infectious diseases can be cured.

16 james watt, 1776 made the first steam engine with practical value. After a series of major improvements, it has become a "universal prime Mover" and has been widely used in industry. He opened up a new era of energy utilization for mankind and made mankind enter the "age of steam". In memory of this great inventor, later generations set the unit of power as "Watt" (abbreviated as "Watt", symbol W).

17 Karl Benz, one of the pioneers of modern automobile industry, is called "the father of automobile". After years of hard work, he finally developed a single-cylinder gasoline engine and installed it on his tricycle frame. Obtained the world's first "automobile manufacturing patent right"

18 gottlieb daimler, 1883 the first gasoline engine, 1886 the world's first four-wheel internal combustion engine car.

19 alfred nobel, 1867 invented the safety explosive.

John von neumann is a Hungarian-born American mathematician, computer scientist and physicist, and one of the most important mathematicians in the 20th century. [1-4] Von Neumann, Ph.D. in Mathematics, Budapest University, is one of the scientific generalists in the fields of modern computer, game theory, nuclear weapons, chemical and biological weapons, and is called "the father of modern computer" and "the father of game theory" by later generations.

2 1 Alessandro Volta, 1800 He made a Volta reactor, and soon invented a Volta battery, which enabled people to obtain a stable and continuous current for the first time.

Nikolaus august otto, 1876, manufactured the first four-stroke cycle gas internal combustion engine. This made it possible for cars and subsequent planes to appear.

Hermann oberth, a German rocket expert, is the father of European rockets, one of the founders of modern astronautics, and a pioneer in space as famous as tsiolkovsky and Goddard. His classic works on rocket propulsion have been regarded as the "Bible" in the aerospace field by a whole generation of engineers.

Thomas Andrews first discovered "supercritical liquid" in 1869.

Alhazen was one of the most important physicists in the Middle Ages. He was interested in optics. Alhazen believes that light is emitted by the sun or other luminous bodies, and then reflected to the human eye by the objects seen. He also correctly explained the principle of lens, that is, the focusing of lens, and made a pinhole imaging machine without lens. He also made a parabolic mirror, which is a component used in today's telescope. His works were translated into Latin and published in16th century, which had a great influence on scientists like Kepler.

Amedeo avogadro published avogadro Hypothesis and avogadro's Law in 18 1 1. At the age of 30, avogadro became interested in studying physics. Later, he went to a rural vocational school to teach, and married Mathea in June of 18 15. 1832, four volumes of theoretical physics were published. In memory of him, Turner was called Avogadro constant.

Anders ?ngstr?m, the first person to determine the Hα spectrum of hydrogen from the gas discharge spectrum, also discovered the spectrum of hydrogen atom, published a standard solar spectrum chart, and recorded the wavelengths of thousands of spectral lines in the solar spectrum. In memory of him, 10- 10 meter was named Egstrom after him, abbreviated as Ai, with the symbol? .

Archimedes is a great philosopher, encyclopedic scientist, mathematician, physicist and mechanic in ancient Greece. He is the founder of statics and hydrostatics and enjoys the reputation of "the father of mechanics". Archimedes, Gauss and Newton are listed as the three greatest mathematicians in the world. [1] Archimedes once said, "Give me a fulcrum and I can pry up the whole earth."

29 miguel alcubierre, 1994, put forward the Akubbery engine named after him, which is a scheme in theoretical physics, and made superluminal navigation possible. Moreover, it will not violate the general theory of relativity that "nothing can travel faster than the speed of light locally".

André-Marie Ampère, the most important achievement of Ampere is his research on electromagnetic action from 1820 to 1827. Maxwell praised it as "Newton in electricity" [1]. He has made outstanding achievements in the research of electromagnetic action. Ampere, the international unit of current, is named after its surname.
