Google on 22nd January 2019 celebrates Soviet Physicist Lev Landau's 111th birth anniversary with a doodle who made some of the most significant discoveries in physics during the 20th century.
Lev Landau co-discovered the density matrix method in quantum mechanics, theory of second-order phase transitions, the theory of Fermi liquid, the Ginzburg-Landau theory of superconductivity among others.
Lev Davidovich Landau was born in Baku on 22nd January 1908, as the son of an engineer and a physician. He died on 1st April 1968.
After graduating from the Physical Department of Leningrad University at the age of 19, he began his scientific career at the Leningrad Physico-Technical Institute.
During 1932 – 1937 he was head of the Theoretical Department of the Ukrainian Physico-Technical Institute at Kharkov, and since 1937 he has been the head of the Theoretical Department of the Institute for Physical Problems of the Academy of Sciences of the U.S.S.R. in Moscow
Lev Landau’s work covers all branches of theoretical physics, ranging from fluid mechanics to quantum field theory.
In 1946 he was elected to the membership of the Academy of Sciences of the U.S.S.R. The U.S.S.R. State Prize was awarded to him several times, and in 1962 he received, jointly with E.M. Lifshitz, the Lenin Science Prize for their Course of Theoretical Physics.
Lev Landau was awarded the Nobel Prize in Physics for his research into liquid helium's behavior at extremely low temperatures in 1962.
