Part 1


The present civilization is on the eve of the third milleni-um of our era. According to some scientists, man has lived on the Harth for over 2,000,000 years. The development1 of human life has been very rapid if we consider man's exist­ence as one long uphill struggle for survival in the severe environment.

One of the greatest philosophers of antiquity Lucretius Carus2, in his poem On the Nature of Things, described how human life changed: man learned to use fire, skins and dwellings and established the laws of marriage and good neighbour! iness.

It took man some 20 thousand years to learn how to use the energy of fire and how to use clay for making pots, to do­mesticate animals and to be able to make the simple clothes for himself. It was some 10 thousand years ago that writing -was invented, and it became possible for people to record and pass on their knowledge about the environment from . generation to generation. It was practically not long ago (in 1454—55)) that the printing press was invented, and so books were used to disseminate knowledge.

A scientific explanation of the world surrounding man began in prehistoric times, probably in Egypt3 s and Baby­lonia4, more than 2,000 years В. С.5. But true progress in science did not begin until the sixth century В. С, when еhe Greek civilization was m full flourish: Any school student an name many contributions made to the development of science and technics in the period from the ancient Greeks to the Renaissance6. The scholars of ancient Greece and Rome say in their records that by the time they came on the scene humanity had gone a long way and had acquired many skills and a great deal of knowledge. From its first steps, the development of science and technology have influenced the growth of our civilization more and more.
