Events Occured in Scienctist Life


Igor Yevgenyevich Tamm (Russian: И́горь Евге́ньевич Тамм, IPA: 8 July 1895 – 12 April 1971) was a Soviet physicist who received the 1958 Nobel Prize in Physics, jointly with Pavel Alekseyevich Cherenkov and Ilya Mikhailovich Frank, for their 1934 discovery of Cherenkov radiation.


At the outbreak of World War I in 1914 he joined the army as a volunteer field medic.


In 1917 he joined the Revolutionary movement and became an active anti-War campaigner, serving on revolutionary committees after the March Revolution.


He returned to the Moscow State University from which he graduated in 1918.


Tamm married Nataliya Shuyskaya (1894–1980) in September 1917.


On 1 May 1923, Tamm began teaching physics at the Second Moscow State University.


In 1928, he spent a few months with Paul Ehrenfest at the University of Leiden and made a life-long friendship with Paul Dirac.


In 1932, Tamm published a paper with his proposal of the concept of surface states.


In 1934, Tamm and Semen Altshuller suggested that the neutron has a non-zero magnetic moment, the idea was met with scepticism at that time, as the neutron was supposed to be an elementary particle with zero charge, and thus could not have a magnetic moment.


In 1945 he developed an approximation method for many-body physics.


As Sidney Dancoff developed it independently in 1950, it is now called the Tamm-Dancoff approximation.


In 1951, together with Andrei Sakharov, Tamm proposed a tokamak system for the realization of CTF on the basis of toroidal magnetic thermonuclear reactor and soon after the first such devices were built by the INF.


Results from the T-3 Soviet magnetic confinement device in 1968, when the plasma parameters unique for that time were obtained, showed temperatures in their machine to be over an order of magnitude higher than what was expected by the rest of the community.


In 1964 he was elected a Member of the German Academy of Sciences Leopoldina.
