⏹ Natta, Giulio Natta

Italian chemist (1903 - )
Natta taught in a number of Italian universities: Pavia, Rome, and Turin. He began his research at the Institute of Technology in Milan, where he headed the Department of Industrial Chemistry.
Drawing on Ziegler's work on catalysts, he discovered
Nata reaction of some and ethylenes, ethylenes
Monocompensation with these aids, which produced a plumeria cluster with a remarkable degree of steric arrangement, regular and called - isotate. Nat and Siegler shared the Nobel Prize for Chemistry in 1963 based on this work.

⏹. Northrup, John Hurd
Northrop, John Howard

American biologist (1891- )
Northrop was educated at Columbia and Harvard • Obtained membership in the Rockefeller Institute for Medical Research after working there as an assistant for a period of time • Worked as a consultant and official student for the National Defense Research Committee. Northrup discovered the process of immersion that leads to the manufacture of «acetone» He also studied enzymes from the interactive point of view (the reaction will strengthen).
He shared with the scientist Stanley the Nobel Prize for Medicine in 1946 as a result of their study of methods for purifying the products of enzymes and viruses. Northrop was able to isolate a number of enzymes, especially digestive and pancreatic.

⏹ Noliyeh, Jean-Antoine Abe
Nollet, Jean Antoine, Abbé

French physicist (1700 - 1770)
Nolih grew up in a toiling agricultural environment. • He learned and reached the position of Professor of Physics in Paris in 1738. He obtained the F.F. R.S and he had friends among the most prominent scholars of his time. We give it the osmotic property, i.e. diffusion through semi-permeable membranes. He also invented an electroscope (electroscope) and an improved electric pot. He has other inventions.

⏹ Neumann, Johann von
Neumann, Johann Von

Hungarian-American mathematician (1903-1957)
Neumann left his country when he was sixteen, so he studied in Berlin and Zurich, then returned to Budapest to continue his studies, and moved to Gettingen.
After he emigrated to America, he taught at the Institute for Advanced Studies (I.A.S) in Princeton. He concluded from the classical research he had done in quantum mechanics that cause and effect act on large things and not on phenomena smaller than an atom. In the atomic bomb project in Los Alamos, during the last world war. His studies on shock waves were used to determine the height of the atomic explosions of Hiroshima and Nagasaki in 1945.
Neumann contributed to the establishment of the theory of continuous groups and the theory of the worker (Oparator theory) and others, which had a major role in building the high-speed computers needed for atomic bomb research · Neumann died of malignant tumors.

⏹ Nipper John Laird of Merchiston
Napier, John, Laird of Merchiston

Scottish athlete ( 1550 - 1617 )
Napier studied at St Andrews and took mathematics as a hobby for him more than a profession.
Nipper's most important achievement was his great invention of logarithms (see Al-Khwarizmi) and his accidental introduction of the decimal notation. Briggs found that the natural base of logarithms (e) is not suitable for normal use, and after consulting Nipier, he produced new logarithmic tables calculated for the base (10) ·
Nipper published his invention of logarithms in a 1614 work titled Mirifici Logarithmorum Canonis Discriptio.
It is noteworthy that the name Napier is written and pronounced incorrectly in the Arabic literature in the form of Napier.

⏹ Nitze, Max Nitze, Max

German surgeon (1848 - 1906)
Nietze was a pioneer in the study of the urinary system—the kidneys, ureters, bladder, and their appurtenances.
He invented the cystoscope (to examine the bladder visually), thus laying the foundation for genitourinary surgery.
