⏹ Hansen, Armor Hansen, Armauer

Norwegian bacteriologist (1841-1912)
Hansen became famous through his work as a doctor in Bergen, as he was a reliable and advanced reference in leprosy at the time. Hansen discovered the bacillus that causes this disease in 1879.

⏹ Amateur, Father Rene Guest
Hauy, Abbe René Just

French mineralogist (1822-1743)
Howie began his educational life studying theology, and when he reached the rank of “Father,” he worked as a professor at the College de Navarre. He also worked as a professor of mineralogy at the Museum of Natural History in Paris. An amateur interested in minerals and noticed the importance of crystallization while he was working on a piece of pure calcite mineral (crystalline calcium carbonate), so he conducted experiments that led him to develop an engineering law in crystallization known as “Hawie’s law, and this law is of great importance in crystallography.” Howe also derived the basic laws in the formation of crystals, and he was the first to reach the relationship between the minerals admiral d and beryl.
His studies on the thermoelectric property of pyro-electricity crystals are also well known.
Howie escaped death at the hands of the rebels, thanks to his student, Geoffroy. St. Eiler (Geoffroy, Saint - Hilair), and years later Napoleon appointed him as a professor of metallurgy, but he was stripped of his post after the fall of Napoleon ·

⏹ Heisenberg, Werner Karl,
Heisenberg, Werner Karl

German physicist (1901-)
Heisenberg received his education in Munich and Gittingen, and was apprenticed by the world Sommerfeld. He became a professor of physics in Leipzig in 1927 and director of the Physical Institute there.
Heisenberg became famous for his studies on Quantum Theory, atomic structure, and the Zeeman effect. Loche founded quantum mechanics in 1925 · Heisenberg developed the principle of indeterminacy.
Rasmi in his name. (This principle is related to the particles of matter in that every material minute must have wave and minute properties at the same time. This is a result of the dependence of the spatial location indeterminacy on the indeterminacy of the momentum of movement.
Heisenberg was awarded the Nobel Prize for Physics in 2008
1932 He assumed a number of important scientific and administrative positions. He was a professor at the university and director of the Planck Institute in Berlin from 1942.
1945, then director of the Planck Institute in Gettingen, a number of valuable books, including: Principles of Quantum Theory in 1930 Prinzipien der Quanten theorie.

⏹ you will turn Johann Wilhelm
Hittorf Johann Wilhelm

German chemist (1824 - 1914).
Hittorf worked as a professor of chemistry at the University of Minster and conducted studies that contributed to the advancement of electrolysis, especially for salt solutions. • Hittorf suggested using transport numbers.
Hittorf studied the electric discharge in rarefied gases using a “Hettorv tube”. • Crookes preceded the physical chemist by studying the effect of the magnetic field on cathode rays. • Hittorf wrote about the migration of ions (electrolytes) during electrolysis in the year 1903-1904.
