Leprovost pauline Chipault Charlotte Linus Pauling

We will present a famous american chemist and physicist named Linus Carl Pauling. Linus Pauling was born 28 February 1901 Portland and he died in 1994 of an ulcer. His Father's name Herman Henry William Pauling and his mother Lucy Isabelle Darling. In 1917, Pauling studied at the Agricultural University of Oregon. During his university studies on the « configuration » of atoms, he studie the work of many physicists like Gilbert Newton Lewis and Irving Langmuir. In 1922, he received his diploma from the University. After he studie on X-ray. He received his PHD in chemistry in 1925.

His family : In 1923, Linus Pauling married with Ava Helen Miller, it will be father of four children : Linus Carl, Peter Jeffres, Edouard Crellin and Linda Helen. His wife died in 1981, Pauling was then alone with his four children.

A currency by Pauling « The best way to have a good idea is to have plenty ! » His findings : Linus Carl Pauling made several discoveries like the biggest bore on the chemical bonds. He made more than 350 comments that have changed science : the crystal structure by X-ray, electronegativity, ferromagnetism, protein structure, etc... He also assisted in finding a medical substance (ascorbic acid) slows and even reduces the risk of certain diseases.

Linus Carl Pauling was a great scholar of the twenthieth century, despite his death, he still provides support for science througt his discoveries and theories. Pauling was not a great chemist, but a model for chemist to come. He tells us that with determination, you come to great things. His discoveries spanned more than 350 areas still useful today. It's debate on the Treaty of Peace in 1963, became known to the world the harmful effects of nuclear testing. Even today, we fight against thes test degrade the environment and cause death.
