⏹ Valach (Valach), Otto, Wallach

German organic chemist (1847-1931)
Valach learned in Gettingen and Berlin and was apprenticed by the great scientist Kékulé.
He worked in his youth in Bonn, where he taught chemistry, then returned to Gettingen • Valach won the Nobel Prize in Chemistry for his work on oils and turbines (volatile hydrogen fuels).

⏹ Wahlberg, Constantine
Fahlberg, Konstantin

- American chemist (1850-1910).
Wahlberg worked at Johns Hopkins University and is best known for his discovery of saccharin
It is a very sweet chemical without nutritional value and its molecular formula is C 7 H 5 O 3 NS and it has been prepared synthetically from toluene.
Wahlberg eventually worked as an industrial chemist.

⏹ Walter, Philipp " Walter

Polish chemist (1810 - 1847)
Walter studied in a number of Polish and French institutes and showed interest in organic and industrial chemical studies. Walter's most prominent work was his experiments in fractional distillation, i.e. distillation at different temperature levels to separate components of varying degrees of boiling, such as oil distillation in special towers. And destructive distillation, i.e. continuous distillation until no volatile substances escalate. Walter was able, in one of his experiments on distillation, with the help of the French chemist Pelletier, to prepare the toluene compound from pipe resin.

⏹ Feifel, Feigel Fritz

Austrian chemist ( 1891 - )
Weigel learned at the Technical University in Vienna, then immigrated to Brazil to head a Belgian industrial enterprise that operates there, then worked as director of the Microscopic Chemistry Department in the Brazilian Ministry of Agriculture and Mineral Products. Weigl discovered more than a hundred new tests for organic materials and groups, thus solving a number of analytical problems that could not be solved by physical methods.
Weigel received the Lomolosov Medal from the USSR Academy of Sciences, and a grant from the Japanese Society of Analytical Chemists.

⏹ Wein, Max Carl

German physicist (1866 - 1938)
Fine worked as an assistant to the scientist Rontgen in «Wirzburg» and then worked as a professor of physics in «Danzig» and in «Pina».
Max Carl Wein and Wilhelm Wein are closely related, as the latter is the uncle of the first.

⏹ What is the story of Auguste Etienne Alban?
Faye, Hervé Auguste Etienne Albans

French astronomer (1814 - 1902)
Faye worked as a professor at the Ecole Polytechnic and then as director of the Paris Observatory. • He discovered a comet and called it Faye. • He developed the theory that links sunspots with the weather.

⏹ Fitzgerald George Francis
Fitzgerald, George Francis

Irish physicist (1851 - 1901)
Fitzgerald learned in Dublin, then worked as a professor of natural philosophy there, and was chosen as a fellow in Fitzgerald's study and the experience of the Royal Society, Michelson-Morley.
In the light of this experiment, it was suggested for the first time that a body moving within a magnetic field could show a contraction in the direction of motion.
This is called the Lorentz-Fitzgerald contraction.
Fitzgerald was also the first to suggest that the tail of the comet consists of small stones whose diameter is less than 1 cm, while the head of the comet consists of large stones (the stones here mean a kind of silicates and iron coals, and they must be distinguished from the iron material that appears in meteorites) in order to explain the reason The aversion shown by the tail of the comet from the light rays emanating from the Sun. Fitzgerald's studies included electrolysis and electromagnetic radiation.

⏹ Farady, Michael

English physicist and chemist (1791-1867)
Faraday began his life poor and worked in bookbinding, and this helped him in reading scientific books, and by introducing him to Davy, the rise began quickly and became a teacher of chemistry at the Royal Institution in 1833.
Faraday discovered electromagnetic induction and introduced induction. Use the word hail dielectric.
Faraday discovered how to produce an electromotive force (QD) by moving a conductor in a magnetic field. He worked on electrical solutions in the experimental field. He has many valuable achievements, especially that he is considered one of the greatest masters of laboratory experiments (laboratory) to devise relationships between the different variables. Faraday is considered the founder of electromagnetism. On New Year's occasions, he gave scientific lectures to young people.
