January 10
Birthdays
Kira Valentinovna Ivanova (10 January 1963 – 18 December, 2001) was a figure skater from the former Soviet Union
whose senior international career ran from 1979 to 1988. While she had
won numerous medals at international events, such as World Junior
Championships, Enia Challenge Cup, and Moscow News Trophy, her true
breakthrough on the international skating scene came with a bronze medal
at the 1984 Winter Olympic Games in Sarajevo, Yugoslavia. Ivanova shined at the 1985 World Figure Skating Championships in Tokyo, where she won the silver medal, finishing second to Katarina Witt.
Andrey Korneyev (born 10 January 1974) is a retired breaststroke swimmer from Russia, who won the bronze medal in the men's 200 m breaststroke event at the 1996 Summer Olympics in Atlanta, United States. A year earlier he captured the gold medal in the same event at the 1995 European Championships in Vienna, Austria.
Vladimir Aleksandrovich Zharkov (born January 10, 1988) is a Russian ice hockey right winger. He is currently playing with the Albany Devils of the American Hockey League (AHL). Zharkov was selected by the New Jersey Devils in the 3rd round (77th overall) of the 2006 NHL Entry Draft.

This day is also birthday of Russian poet and literary critic Pyotr Alexandrovich Pletnyov(1792). Pletnyov befriended the poet Alexander Pushkin, who dedicated his novel in verse Eugene Onegin to him. After Pushkin's death in 1837, Pletnyov edited his literary journal Sovremennik until the latter was sold to Nikolai Nekrasov in 1846. As a critic, he was strongly opposed to Vissarion Belinsky and like-minded journalists who placed "progressive ideas" above the artistic mastership.
ReplyDeleteGrigory Samuilovich Landsberg (January 22, 1890, Vologda - February 2, 1957, Moscow) was a Soviet physicist. Grigory S. Landsberg is a co-discoverer of inelastic combinatorial scattering of light used now in Raman spectroscopy. His major scientific contributions were in the fields of optics and spectroscopy.
ReplyDeleteBeginning from 1926, L.I. Mandelstam and G.S. Landsberg initiated experimental studies on vibrational scattering of light in crystals at the Moscow State University. Their intention was to prove the theoretical prediction made by Mandelstam in 1918 regarding the fine structure splitting in Rayleigh scattering due to light scattering on thermal acoustic waves. As a result of this research, Landsberg and Mandelstam discovered the effect of the inelastic combinatorial scattering of light on 21 February 1928 ("combinatorial" – from combination of frequencies of photons and molecular vibrations). They presented this fundamental discovery for the first time at a colloquium on 27 April 1928. They published brief reports about this discovery (experimental results with theoretical explanation) in Russian and in German and then published a comprehensive paper in Zeitschrift fur Physik.
In the same year of 1928, two Indian scientists C.V. Raman and K.S. Krishnan were looking for "Compton component" of scattered light in liquids and vapors. They found the same combinatorial scattering of light. Raman stated that "The line spectrum of the new radiation was first seen on 28 February 1928." Thus, combinatorial scattering of light was discovered by Mandelstam and Landsberg a week earlier than by Raman and Krishnan. However, the phenomenon became known as Raman effect because Raman published his results earlier than Landsherg and Mandelstam did. Nonetheless, in the Russian-language literature it is traditionally called "combinatorial scattering of light".
