On April 1, 2018, it will complete fifty years of the death of one of the scientists who contributed most to the development of physics in the 20th century, the Russian Lev Davidovich Landau. He was born on January 22, 1908 in Baku, Azerbaijan, in what was then the Russian Empire. He was a prominent soviet physicist who made fundamental contributions to many areas of theoretical physics. He received the 1962 Nobel Prize in Physics for his theory of super fluidity that accounts for the properties of liquid helium. On January, 1962, Landau was seriously injured in an automobile accident and remained three months in a coma, being declared clinically dead four times. Recovered, he lived another six years. Landau died on April, 1968, aged 60, from complications from the accident. The case involving Landau introduces a conflict related to the removal of organs from people believed to be brain dead.
