Linus Pauling Memes.

Linus Carl Pauling (/ˈpɔːlɪŋ/; February 28, 1901 – August 19, 1994)[4] was an American chemistbiochemistpeace activist, author, educator, and husband of American human rights activist Ava Helen Pauling. He published more than 1,200 papers and books, of which about 850 dealt with scientific topics.[5] New Scientist called him one of the 20 greatest scientists of all time,[6] and as of 2000, he was rated the 16th most important scientist in history.[7]

Pauling was one of the founders of the fields of quantum chemistry and molecular biology.[8] His contributions to the theory of the chemical bond include the concept of orbital hybridisation and the first accurate scale of electronegativities of the elements. Pauling also worked on the structures of biological molecules, and showed the importance of the alpha helix and beta sheet in protein secondary structure. Pauling’s approach combined methods and results from X-ray crystallographymolecular model building and quantum chemistry. His discoveries inspired the work of James Watson and Francis Crick on the structure of DNA, which in turn made it possible for geneticists to crack the DNA code of all organisms.[9]
