⏹ Glaisher, James Glaisher

English meteorologist (1809-1903)
Gleicher began his working life as a surveyor and was promoted to assistant observer and then to chief meteorologist at the Greenwich Observatory. Glaisher founded the Meteorological Society (M.S.) and was chosen as a Fellow of the Royal Society in 1849. He made a number of balloon ascents, one of which reached seven. Glaisher wrote a number of thirty thousand feet of scientific books, and he also prepared very important tables about “the dew point.” » in measuring relative humidity.

⏹ Agents, Leopold Gmelin, Leopold

German chemist (1788 - 1853)
Gmeln was one of a family famous for its large number of scholars, and he was the most prominent of them. Gmeln studied medicine and chemistry in Göttingen, Tibingen, and Vienna.
Then he worked as a professor of chemistry in Heidelberg. In 1822, Gmelin discovered the salt that bears his name, "Gmeln's salt, which is the red Prussian of potash or potassium iron cyanide. He also discovered important organic substances. Gmelin was the first to use the word "ester", the word "ketone", in chemistry in 1848. His book entitled: Handbuch der anorganischen Chemie Inorganic Chemistry is considered, after it has been reviewed and revised, as an important and standard reference in organic chemistry. There is a discovery of gall dyes (yellow) known as Gemelin's detection, and it is also mentioned that Johann Friedrich, father of Leopold Gemeln, wrote a book entitled: History Chemistry. Geschichte der Chemie.

⏹ Gunter, Edmund Gunter,

English mathematician and astronomer (1581-1626)
He has important achievements in mathematics and many inventions, the most important of which is the logarithmic scale on which the calculator ruler is based.

⏹ Frederick Augustus sang
Genth, Frederick Augustus

German-American mineralogist (1820-1893)
. Ghent learned in Giessen and Marburg, then emigrated to America at the age of twenty-eight in 1848, where he worked as a professor of chemistry and minerals in Pennsylvania. Ghent's research was famous for ammonium cobalt compounds, as well as for his discovery of twenty-four new minerals.

⏹ Goodrick, John Goodrick,

English astronomer (1764 - 1786)
Godric was the first to conduct an accurate study of the changes of the star “Ras al-Ghul” (Algol), and he indicated, when he was not more than eighteen years old, that these changes arise from a dark body that revolves around a luminous body, causing an eclipse. Copley medal for his research on variable stars, and Gordrik was chosen as a Fellow of the Royal Society while he is in his final year.

⏹ Gould, Benjamin Apthorp
Gould, Benjamin Apthorp

American astronomer (1824 - 1896)
. A student of the German physicist Gauss in Göttingen, Gould did a great deal of work surveying the coast of the United States and studying standard stars using navigational astronomy. Navigational Astronomy Ats Gould is the Argentine Observatory in Cordoba. It collected a number of wonderful astronomical photos such as: Uranomenturia Argentina. It is mentioned that Gould died in a fall from the stairs.

⏹ Goldberg, Calo Maximilian
Maximilian Goldberg , Cato

Norwegian mathematician (1836 - 1902)
Goldberg was educated at the University of Christiania
Then he worked there as a professor of applied mathematics. He did advanced studies in thermal kinetics (thermodynamics) and in chemical equilibrium. He participated with his son-in-law, Waage, in formulating “The Law of Mass Action,” which states: The speed of a homogeneous chemical reaction is proportional to the concentration of the product of the reactants. .

⏹ Goldstein, Eugen Goldstein, Eugen

German physicist (1850 - 1931)
Goldstein was educated in Berlin, then took a job as a physicist at the Berlin Observatory.
Goldstein was the first to notice the shadows of cathode radiations (cathodes) and that they emanated at a right angle to the source surface in the year 1876. Ten years later, he discovered what he called “channel radiations”, which are positively charged atomic particles emanating from the cathode in a direction opposite to the cathode radiations.

⏹ Goldschmidt, Richard Benedict
Goldschmidt, Richard Benedict

German-American biologist (1878-?).
Goldschmidt taught in Munich, then left to work as director of the Kaiser Wilhelm Institute in Berlin. And then at the University of Tokyo for about four years, then he worked as a professor of animal teacher at the University of California. Goldschmidt was a reference in genetics problems. He conducted continuous and important experiments on the X chromosomes, using butterflies in that.
A theory that says: that the sequential arrangement of chromosomes (colored bodies) and the chemical conformation of the chromosome molecule are more decisive factors in heredity than they are the qualities of a single species.
Among Goldschmidt's most important books: Genetics (Die Lehre Von der Vererbung),
And intermediate carriers in sex (Die Sexuellen Zwichenstufen), physiological genetics, and the material basis of evolution (The Material Basis of Evolution).
