Часть полного текста документа:Outstanding personalities Russia gave the world a lot of great writers, artists, musicians, philosophers, sportsmen, and politicians. The names of Russian scientists and inventors are known all over the world. Almost in all branches of science and technology the Russian scientists played the leading role. The achievements of the Russian scientists are great. Vladimir Vernadsky (1863-1945), a Russian scientist, is considered to be one of the founders of geochemistry and biogeochemistry. The son of a professor, Vernadsky graduated from St. Petersburg University in 1885 and became curator of the university's mineralogical collection in 1886. In 1890 he became a lecturer on mineralogy and crystallography at Moscow University, where he earned his Ph.D. in 1897. He served as a professor at Moscow University from 1898 to 1911. After the Revolution he was active in scientific and organisational activities. He founded and directed (from 1927) the biogeochemical laboratory of the Academy of Sciences at Leningrad (St. Petersburg). Vernadsky's initial work was in mineralogy. He was also a pioneer in geochemistry. He made a detailed study of the Earth and chemical processes going on in its crust, including the migration of chemical elements. Vernadsky was one of the first scientists to recognise the tremendous potential of radioactivity as a source of energy, and he was also one of the first to put forward the idea that radioactivity is vital to many processes of the Earth's life. His later years were taken up with the study of the life processes in the atmosphere and in the Earth's crust. Vernadsky is regarded the founder of the theory of the biosphere, that is the total mass of living organisms, which process and recycle the energy and nutrients available from the environment. His name is well known today. For example, an avenue and a metro station in Moscow bear the name of Vernadsky. I also admire the work of Alexander Tchijevsky (1897-1964), a Russian scientist of space biophysics, and a young friend of Tsiolkovsky. Konstantin Tsiolkovsky (1857-1935) was among the first to work out the theoretical problems of rocket travel in space. He is the greatest Russian research scientist in aeronautics and astronautics who pioneered rocket and space research. Tchijevsky worked in the tradition of late Cosmic Philosophy. The son of a Russian general, Tchijevsky spent the early years of his life in Kaluga. There he got his education and then worked. In this town he made friends with Tsiolkovsky, who became his advisor and scientific colleague. For the rest of his life Tchijevsky lived and worked at different research institutions in Moscow. His theories of sunspot activity and human activity stated that sunspot cycle activity increased and decreased in a cycle of approximately 11 years. During World War I Tchijevsky continued his studies at the war front. He noticed that a dependence existed between the severe battles and solar activity. To test his hypothesis that sunspot cycle influenced human lives, Tchijevsky analysed the data covering each year form 500 BC to 1922 AD. Then he studied the histories of 72 countries during that period, noting signs of human unrest such as wars, revolutions, riots, expeditions and migrations. Tchijevsky found that 80 percent of the most significant events occurred during the years of maximum sunspot activity. Tchijevsky observed that the Russian Revolution of 1917 occurred during the height of the sunspot activity. The scientist spent long years in Soviet prisons because his theory challenged the established system. Tchijevsky did not believe that solar disturbances caused discontent among people. Solar activity simply served as detonators that set off the reaction of the people who had many grievances and causes for complaint. The recent studies tend to confirm Tchijevsky's hypothesis. - Can you tell us about an outstanding American personality? - John Fitzgerald Kennedy (1917-1963), 35th president of the United States (1961-63), faced a number of foreign crises, especially in Cuba and Berlin, but managed to secure such achievements as the Nuclear Test-Ban Treaty and the Alliance for Progress. John Kennedy grew up in a large family. He was the second of nine children, and his father wanted all his children to compete physically and intellectually with each other. Kennedy graduated from Harvard University. For six months in 1938 he served as secretary to his father, then U.S. ambassador to Great Britain. In the fall of 1941 Kennedy joined the U.S. Navy and two years later was sent to fight in the Pacific against the Japanese during Word War II. Originally John's elder brother was to become the U.S. president, but he was killed during the war. So, John who originally planned to become a scholar or a journalist was to replace his brother. In 1960 the Democratic Party nominated Kennedy as its official candidate for the presidency. In 1960 John Kennedy became one of the most famous political figures in the country. He was young and ambitious, people believed that he would open a new era in the American history. During the television debates Kennedy appeared as a good looking and promising person. Kennedy won the election and in 1961 he became the president of the United States. John F. Kennedy was the youngest man and the first Roman Catholic ever elected to the presidency of the United States. His slogan was "Let's get this country moving again". His administration lasted 1,037 days. From the onset he was concerned with foreign affairs. Kennedy was an immensely popular president, at home and abroad. ............ |
