In 2006, the great chemist, 1954 Nobel Prize winner in chemistry, the famous master of chemical structure, Pauling (Linus? Pauling) is one of the founders of modern chemistry in America. He is regarded as "Frankenstein". In his 94-year legendary career, Pauling grew from the son of a small-town drugstore owner in Oregon to a master of science who made great achievements in many fields, and later became a fighter of the world peace movement.

With his extraordinary achievements and experiences, he won the 1954 Nobel Prize in Chemistry and the 1962 Nobel Peace Prize, becoming the only scholar who won the Nobel Prize twice. 1994 The old man died in this century. When people opened his office, they found that the blackboard was full of pictures, including a structural formula of C6H2O2N 10/0.
