It is difficult to value the role of scientific invention of the second half of XX century. But we shouldn’t forget that it is would have been impossible without countless ideas and inventions which mankind had made before. Every minute of our life is history in the making. Nowadays technical progress is developing so fast, that people who lived 50 years ago even couldn’t imagine our modern way of life. They couldn’t realize things, which is widespread and habitual for us. Today’s events can soon enter history books as well. As for me, it is difficult to pick out three the most important inventions from inventions which are not less important than them. So I think that the most significant inventions and events of the last 50 years are: invention of computer, internet and the latest discovery is cloning, which has been made not long ago, in 1997. Our century is a century of developing informational connection.
