It’s difficult to overestimate the role of science and technology in our life. They accelerate the development of civilization and help us in our co-operation with nature.

Scientists investigate the laws of the universe, discover the secrets of nature, and apply their knowledge in practice improving the life of people. Let's compare our life nowadays with the life of people at the beginning of the 20th century. It has changed beyond recognition. Our ancestors hadn't the slightest idea of the trivial things created by the scientific progress that we use in our everyday life. 


    First of all America is the name of the country – The United States of America – or just America. And then America is the name of the two  continents – North and South America.

    Christopher Columbus discovered America in 1492. He was born in Italy. He was a seaman. He made many sea voyages.

    He wanted to go to India and he decided to sail west as he was sure that our planet was round. Christopher Columbus reached some land but it wasn’t India. He discovered some islands in Central America.

All public access to an airport is channelled through the terminal, where every person must walk through a metal detector and all items must go through an X.ray machine. Metal detectors have been a staple of airport security for decades. Nowadays airline passengers can skip metal detectors and instead are screened by body scanning machines that look through clothing.

    One of the most important security measures at an airport is confirming the identity of travellers. This is done by checking a photo ID, such as a driver's licence. The term “photo identification” (or photo ID) is generally used to define any form of identity document that includes a photograph of the holder. If you are travelling internationally, you need to present your passport. Simply taking a look at a photo ID isn't enough, however.  The high.tech buzzword in airport security today is biometrics.
