⏹ Faber, Jean Henri Fabre, Jean Henri

French entomologist (1823-1915)
Faber grew up in a humble environment, then worked as a teacher and continued to obtain a doctorate from the University of Paris, after which he worked as a professor of physics at the College of Ajaccio.
Faber took the study of insects as an integral part of his life, and the results of his study won international fame, but his observations led him to oppose the theory of evolution.

⏹ Faber, Johannes Faber,

German scientist (1574 - 1629)
Faber was distinguished by being one of the founders of the first scientific association to call it Lynx, i.e. a cat of the lynx type, and it is distinguished by its sharp shape, especially the face and eyes.
Faber used the word microscope for the magnifying device (microscope), which was at that time newly invented.

⏹ Fabricius, AB Aquabandana, Hieronymus
Fabricius ab acquapendente, Hieronymus

Italian anatomist (1537-1619)
Fabricius received his education in Padua, then worked there as a professor of anatomy, succeeding Fallopius.
. Fabricius discovered the semi-lunar valves in the veins, but he failed to understand their role in passing blood in one direction, as explained later by his distinguished student, Doctor Harvey (1578-1657), who discovered the true circulation of blood (see Ibn al-Nafis). .
Fabricius carried out studies in embryology that enjoyed great importance and fame, and Fabricius is considered the founder of embryology.

⏹ Fajan (Fayan), Kazimir Fajan, Kasimir

Polish-American physical chemist (-1887)
Fagan studied in Leipzig and Heidelberg, then in Manchester, and worked as a professor of chemistry in Munich and then in Michigan. Fagan developed the theory of isotopes independently of Soddy to explain the existence of elements with the same atomic numbers but different atomic weights. It should be noted that Aston (from 1877 to 1945) has proven the existence of such isotopes through mass spectroscopic study. mass spectroscopy. Fagan participated with Göhring in a statement that uranium Q1 decomposes by releasing “beta” radiation, B, giving uranium Q2, which they called in relation to the “brevium” palace during his lifetime. Fagan studied the reconstruction of minerals in Norway by estimating the final product (after radiation), which is lead. He also carried out studies on the hydration energy of ions. (The energy released when the ion of hydration is free in the gaseous state enters the water) • Fagan authored a book entitled: Radioactivity and Latest Developments in the Study of Chemical Elements.
He also wrote a book entitled: Radioelements and Isotopes.

⏹ Warburg, Otto Heinrich
Warburg, Otto Heinrich

German physiologist (1883-)
Varburg studied in Berlin and Heidelberg · He worked at the Kaiser Wilhelm Institute of Biology and had the opportunity to conduct studies on respiration, enzymes and some dangerous diseases · He won the Nobel Prize for Medicine in 1931.

⏹ Farnheit, Gabriel Daniel
Fehrenheit, Gabriel Daniel

German physicist (1686 - 1736)
He learned natural philosophy in Holland, and became a Fellow of the Royal Society in 1724. During his study of heat, he improved thermometers and used mercury in them.
A degree of Fahrenheit is equal to five scales (5/9) of a degree Celsius. According to the Franhaiti system, the freezing point of water is 32 F, and its boiling point is 212 F.

⏹ Wagner-Jauerg, Julius
Julius Wagner - Jauregg ,

Austrian neuroscientist and psychiatrist (1857-1940)
Wagner-Jauerg studied in Vienna and worked as a professor of psychotherapy (nervousness). He studied the thyroid gland and its relationship to deviant fetal growth. Wagner-Jauerg became famous as a result of his treatment of general paralysis caused by infection with malarial disease, and for this he was awarded the Nobel Prize for Medicine in 1927.

⏹ Vavilov, Nikolai Ivanovich
Vavilov, Nikolai Ivanovich

ethnologist, botanist, Soviet (1891-1942)
Feiflov specialized in the study of plant varieties and families, and he is the brother of the famous physicist Sergei.
Vavilov was appointed director of agricultural research and established 400 agricultural research institutes in the Soviet Union. Among his important research on the different groups of wheat varieties, Vavilov reached the establishment of the bases of an important principle, which is the principle of diversity, which links plant varieties and geographical conditions. Vavilov was a foreign member of the British Royal Society. He spent his last days in exile in Siberia.
