full - time education. In practice means that the children are compelled to go to school.

A child who lives in a town flat or a city street needs somewhere to spend the day or part of it, where he can run about and play it safety with someone keeping an eye on him.

Post school education is organized fiexibly, providing wide range of opportunities foe academic and vacation education and to continue studying through out life.

contributions to world science which influencedthe work of the progressive scientists of his time. It is difficult to enumerate his many-sidedscientific activities.Lomonosov was a complete master of natural sciences especially in chemistry and physicsand it was with Lomonosov that geology, mineralogy, geochemistry, physical chemistry, miningand many other branches of science began. He took great interest in history and mathematics andhe is considered to be the founder of Russian materialistic philosophy. Besides all thisLomonosov is known to have been a poet. His literary works remain the most significant, pagesof Russian literature which influenced the development of Russian poetry.Lomonosov is also known to be the author of the first Russian grammar book. In additionto the Russian Lomonosov had a perfect command of many foreign Languages such as Latin,French, German and ancient Greek.Lomonosov was a prominent Russian artist and he is known to have made a greatcontribution to the development of Russian pictorial act.We know Lomonosov's life to be full of difficulties and obstacles which he had toovercome. His father wanted Michail to become a fisher man. But Lomonosov's desire tostudy was so great that at the age of 19 he started to Moscow on foot to enter the Slavonic-GreekLatin Academy. His scientific career lasted 25 years was marked by a striking capasity for work.In these 25 years he carried out a gigantic amount of work in various branches of science,engineering and art. He fought for educating his people and he is sure to have done the best toestablish schools all over the country.By the end of his life Lomonosov had been elected honorary member of a number offoreign academies.

succeswsive generatiions of computers to see what their operaiting systems were like. The first true digital computer was designed by the English mathematician Charles Babbage (1792-1871). Although Babbage spent most of his life and fortune trying to build his "analytical engine,"he never got it working properly because it was purely mechanical,and the technology of his day could not produce the required wheels, gears, and cogs to the high precision that he needed. Needless to say, the analytycal engine did not have an operaiting system. Babbage realized that he would need soft ware for his analytycal engine, so he hired a young woman named Ada Lovelace, who was the daughter of the famed British poet Lord Byron, as the world's first programmer. The programming language Ada is named after her. After Babbage's unsuccessful effrts, little progress was made in constructing digital computers until World War ll. Around the mid-1940s, Howard Aiken at Harvard , John von Neumann at the Institute for Advanced Study in Princeton,J. Presper Eckert and William Mauchley at the University of Pennsylvania, and Konrad Zuse in Germany,among others , all succeeded in building calculating engines. The first ones used mechanical relays but were very slow, with cycle times measured in seconds. Relays were later replaced by vacuum tubes.These machines were enormous, filling up entire rooms with tens of thousands of vacuum tubes,but they were still millions of times slower than even the cheapest personal computers available today. In these early days asingle group of people designed,built,programmed, operaited,and maintainat each machine.All programmig was done in absolute machine language,often by wiring up plug boards to control the machine's basiv functions.
