Complete 6 pages APA formatted article: Russian scientists' contribution in the world science. Economist and Noble prize winner Leonid Vitaliyevich Kantorovich, founder of linear programming. Nikolai Basov, who invented laser. Now, in this assignment let us discuss in detail the hurdles faced by them through the process of innovations and life history. Dmitri Mendedleev: One of the great scientists of Russia is the Dmitri Mendelev, survived from 1834 to 1907 and has contributed the precious Periodic Table of Elements. The story began when the atomic weights of elements were derived wrongly. As a result incorrect compounds were found to be formed. So there resulted a serious confusion in determining the characteristics of elements and their atomic weights (Allaby & Gjertsen, 2002). It was stated that Mendeleev derived the Periodic table in his dreams. Mendeleev had the vision of the Periodic table in his mind but unable to put them in to table. He worked continuously for three days to create the table. Ultimately he slept in his table and had a dream of the arranging the 63 elements in the Periodic Table of Elements. Then he wake up from the dream and derived the table that he dreamt. It was perfectly correct with only few corrections made in it. It took nearly 20 years to construct this precious table and his contribution helped greatly to learn the characteristics and property of the elements. Later he discovered Gallium, Scandium and Germanium. He worked as a professor at the St. University of Petersburg from 1868 to 1890. His other studies and contributions are Nature of solutions Expansion of liquids 40° vodka formula 30 components formula derived in 5 rows. This was so simple and precise that his findings exceeded all the works of his predecessors. The derivation of 40° vodka formula was really an interesting story. It was the time world over running researches on weight analysis on alcoholic solutions. Mendeleev received the accurate results by missing the alcohol with water based on weights while the whole other world used to mix by volumes. Then he formulated as the precise content of spirit in vodka to be 40°. Upon reciprocal dilution the largest compression a mixture can be made. That is 45.88% of anhydrous spirit can be mixed with 54.12% of water. To explain this exactly 1 liter of 40° vodka weights 951 grams exactly (Allaby & Gjertsen, 2002). Sergei Vasilyevich Lebedev: Lebedev was born in 1834 in Lubin. He completed his graduation at St. Petersburg University. After his graduation he moved from university to university in charge of the work and finally settled down at the Petersburg Margarine Factory (Encyclopedia Britannica Inc, 2002). His main works are devoted to the invention of the polymerization of the hydrocarbons of ‘diene’ type. He was the first to produce the polybutadiene synthetic rubber. This synthetic rubber replaced the natural rubber and was produced during World War I as there was a shortage of natural rubber. His wrote a book named as ‘Research in polymerization of by-ethylene hydrocarbons’ in 1913, which became the basics guide for studies on synthetic rubber. He also introduced the modern methods which lead to the manufacture of the butyl synthetic rubber and poly iso-butylene with the help of his studies on polymerization of ethylene monomers. The access of reliable sources to natural rubber was difficult to Russians. Hence the mass production of the synthetic rubber was essential and this was launched in 1932. In 1940, they produced more than 50,000 tons per year.
