⏹ Captain, Jacobus Cortelius
Kapteyn, Jacobus Cornelius

Dutch astronomer (1889 - )
Kaptein worked as a professor of astronomy in Groningen, and he was one of the greatest astronomers of his time. Kaptein was able to show that all the stars whose true motion can be investigated fall under one of two systems (two rivers) of stars moving in different directions, and that the speed of one of these two rivers is three times the speed of the other. And that the sun is located in the river of slower speed, and he prepared pictures of the stars of the southern hemisphere, and he participated with Rien (Rijn) in formulating a theory about the universe.

⏹ Kaplan, Joseph

American physicist (1902 - )
Kaplan was born to Hungarian parents, and his family traveled to America when he was eight years old.
Kaplan studied at John Hopkins University, then worked as a research fellow at Princeton, then worked as a professor of physics at the University of California. Kaplan's research on the subject of spectrum became famous, as he was able to produce the auroral spectrum in the laboratory and discovered a spectrum of nitrogen in the Earth's upper atmosphere.

⏹ Kapitsa Peter ( Peter Leonidovich Kapitsa )
Kapitza , Peter ( Peter Leonidovich Kapitza )

Russian physicist (1894 - )
Kapitsa was educated in Petrograd and Cambridge, where he became acquainted with Rutherford.
Then he worked as an assistant director of magnetic research in the Cavendish Laboratory and worked as a research professor at the Mond Laboratory of the Royal Society. Kapitsa's studies on magnetism and low temperatures, especially with regard to producing magnetic fields of up to 300,000 gauss, are well known.
He also worked on the design of machines for the liquefaction of hydrogen and helium (Kaptsa held the position of director of the “Institute of Physical Problems” in Moscow.

⏹ Cataldi, Pierre Antoine
Pierre Antoine Cataldi

Italian mathematician (1548 - 1626)
Cataldi was distinguished by being one of the first mathematicians who devoted much of their time to conducting numerical calculations, and in 1613 Cataldi developed continuous fractions to extract roots. Cataldi worked as a professor of quadratic mathematics. At the University of Bologna, where he established the first sports academies.

⏹ Cadet, de Gascourt, Louis Claude
Cadet, de Gassicort, Louis Claude

French chemist (1731 - 1799) ·
Kadeh was a member of the Academy of Sciences, and he worked in practical chemistry.
In 1760, Kade was able to prepare a compound that was characterized by the worst smell of a chemical compound, and it was a liquid known as “the stinky,” or “the stinky,” characterized by its brown color and horrible smell. From this compound, the chemist Bunzen separated the “cacodyl” oxide (C4 H12 OAS 2).
The cacodyl oxide is prepared by distilling equal quantities of potassium acetate and arsenichor oxide.

⏹ Karrer, Paul

Swedish chemist (probably of Swiss origin).
( 1889 - )

Karr was born in Moscow and educated in Zurich, where he later worked as a professor of organic chemistry.
He collaborated with the scientist Ehrlich in Frankfurt.
He has pioneering works and studies on vitamins, particularly vitamins A and B, as well as carrots and flavins (which are pigments with enzymatic properties).
Carr shared with Sir Walter Haworth the Nobel Prize in Chemistry in 1937.

⏹ Carson, Rachel Lewis
Carson, Rachel Louise

American scientist and author (1907-)
Carson was educated at Pennsylvania College for Women and at Hopkins University.
Peace Services Carson served as editor-in-chief of a magazine
Fish and Wildlife Services.
She received a grant of literature from the Council of Women of the United States, and then won the Swiss Prize for Animal Welfare. Carson did many researches on chemical pesticides, and explained in her book Silent Spring that the amount of pesticides used on California farms alone is sufficient to kill fifteen thousand million people. every year .

⏹ Carrington, Richard Christopher
Carrington, Richard Christopher

English astronomer (1826 - 1875)
Carrington learned in Cambridge, then worked as an observer at Durham University Observatory, and finally set up a private observatory in Redhill and conducted studies of sunspots that lasted eight years. Carrington explained that the rotation of sunspots depends on the latitudes located on them from the surface of the sun.
Carrington was elected a Fellow of the Royal Society, and his life came to a tragic end.

⏹ Carnot, Nicolas Leonard Sadie
Nicolas Carnot, Leonard Sadi

French scientist and military (1796 - 1832)
Carnot was an officer in the French army and was interested in kinetic thermocycling machines known as thermodynamics

Carnot Cycle He wrote a book on the basis of thermodynamics, (Thermodynamics), which is one of the greatest works in science. He contracted cholera and died with it.
