Editing Lev Landau (section)

===National Scientific Center Kharkiv Institute of Physics and Technology, Kharkiv===
Between 1932 and 1937, Landau headed the Department of Theoretical Physics at the National Scientific Center [[Kharkiv Institute of Physics and Technology]], and he lectured at the [[University of Kharkiv]] and the [[Kharkiv Polytechnic Institute]]. Apart from his theoretical accomplishments, Landau was the principal founder of a great tradition of theoretical physics in [[Kharkiv]], Ukraine, sometimes referred to as the "Landau school". In Kharkiv, he and his friend and former student, [[Evgeny Lifshitz]], began writing the ''[[Course of Theoretical Physics]]'', ten volumes that together span the whole of the subject and are still widely used as [[Graduate school|graduate]]-level physics texts. During the [[Great Purge]], Landau was investigated within the [[UPTI Affair]] in Kharkiv, but he managed to leave for [[Moscow]] to take up a new post.<ref name=ScientificAmerican1997/>

Landau developed a famous comprehensive exam called the "Theoretical Minimum" which students were expected to pass before admission to the school. The exam covered all aspects of theoretical physics, and between 1934 and 1961 only 43 candidates passed, but those who did later became quite notable theoretical physicists.<ref>{{cite book|author=Blundell, Stephen J.|title=Superconductivity: A Very Short Introduction|year=2009|publisher=Oxford U.
