Lev Landau was a well-known Soviet theoretical physicist. He was an exceptionally brilliant student and completed his primary as well as advanced education at a very young age. Lev Landau became interested in the field of theoretical physics during his graduation and later went on to focus on research in this field. During his career, he contributed much to science with discoveries like the free energy calculation theory, theory of superfluidity and explanations regarding dimagnetism, the Landau spectrum and so on. His theories provided a base to condensed-matter physics in the 20th century. Apart from research, he taught at the Kharkiv University and the Moscow State University. He received prestigious awards such as Nobel Prize in Physics and the Max Planck Medal. He was associated with several prominent institutes like the Royal Society of London and National Academy of Sciences in the U.S.A. In his honour, his co-workers and students built an institute specializing in theoretical physics in Russia. Two celestial bodies have also been named after him.
