⏹ Lewis, Warren Kendall
Lewis, Warren Kendall

American chemist ( 1882 - )
Lewis studied at the Massachusetts Institute of Technology, then in Breslau, and returned to Massachusetts to work as a professor of chemical engineering. Lewis conducted original studies on the thermal properties of materials, as well as the properties of colloidal materials.

⏹ Lee " Marius Sophos
Lie, Marius Sophus

Norwegian athlete (1842 - 1899) ·
Lee studied at Christiania University in Oslo, then worked there as a private teacher, then as a professor of mathematics. Lee moved to Leipzig to teach mathematics there, then returned to his first university. Lee became famous because of his theory of tangential transformations, especially transformations related to a ball that meets a straight line. My greatest publication was: Transformational Group Theory
Theory of Transformationsgruppen
appeared in 1893.

⏹ Libavius, Andreas (Libau)
Libavius ​​, Andreas ( Libau )

German chemist (1540 - 1616)
Libavius ​​(Libao) worked as a school principal and was interested in chemical studies, so he wrote a book that is considered the first chemical reference of its kind, and Libavius ​​was one of those who believed that cheap elements could be converted into valuable ones. He had useful chemical experiments, and he mentions his discovery of tinnitus chloride.

⏹ Liebig, Justus Baron von
Liebig Justus Baron Von

German chemist with great knowledge (1803-1873)
Liebig received his education in Bonn and then in Paris, where he met the scientist «Gay-Lussac» • He worked as a professor of chemistry in Gießen and Munich, and opened a chemistry institute that was internationally renowned. He has very extensive achievements in organic chemistry, and he has developed advanced scientific views on nutrition, food, metabolism, and agriculture. He is truly the founder of agricultural chemistry. He invented a method for making mirrors (silver) and invented a condenser called a Liebg condenser. He also invented a method for extracting fats, meat extracts and other similar materials.

Liebig was the first to realize that the heat generated in the animal's body is a result of the combustion of food, and the first to divide the food into fats, carbohydrates and proteins, and in 1832 he found that meat extracts contain lactic acid.

He introduced to want the use of synthetic fertilizers in agriculture. He showed that plants absorb minerals from the soil and absorb carbon and nitrogen from the atmosphere.

⏹ Leith, Charles Kenneth
Leith, Charles Kenneth

American geologist (1875 - 1956)
Laith was educated in Wisconsin and Columbia, then returned to Wisconsin to work as an advisor on mineral wealth affairs to the US government.
Laith calculated the proportions of sedimentary rocks represented by shale clay, sandstone, and limestone.

⏹ Legendary Adrienne Marie
Legendre, Adrien Marie

French mathematician (1752 - 1833)
Legendre received his education in Paris and then worked as a professor of mathematics at the Military Academy • Legendre played a major role in measuring the degree of latitude between the cities of Dunkirk and Bologna.
Legendre's relationship with the famous mathematician, Laplace, was bad and full of hatred, which reduced the appearance of Legendre • However, his works on elliptic functions, Elliptic functions (1827) constitute a great achievement in mathematics.
His study of the theory of numbers (1798) and its consecration of the Law of quadratic reciprocity is an important contribution to mathematics. Legendre was interested in studying the least squares, and he published a book on geometry in 1794.
