Some wonders of modern science

Science has been worked miracles in the field of science and there seems to be nothing that he cannot achieve.

The most important recent inventions have been in the field of electronics and computers. Computers perform complex calculations in a fraction of the time that would have been needed in the past. They help to run businesses economically and safely. Aircraft and ships use computers to monitor things like geographical position and fuel consumption.

Electronic devices have made robots a reality. Many factories now have robots that do several tasks such as painting and welding. Engineers have also developed `intelligent’ robots, which can act as guards and firemen, and may travel into space to distant worlds.

For hundreds of years man had dreamed traveling in space. Now that dream came true. Unmanned craft are equipped with instruments to send television pictures and scientific information back to earth. They travel through the solar system and beyond, photographing planets.

Not many years ago, information could be carried from one part of the world to another only by cables under or over the ground, or be broadcast from radio transmitters. To day satellites are used in the world-wide network of telecommunications. Communications satellites are placed in orbit above the earth so that they can bounce radio signals from one part of the world to another. It is satellites that enable us to see on television events that are happening on the other side of the world a fraction of a second after they take place.

Rapid development in modern medicine has conquered many diseases and disorders. The latest developments include body scanners, which can produce a detailed picture of the interior of the human body. Radio- therapy is often used to cure cancer. Today surgery is so advanced that surgeons can repair or replace organs such as the kidneys and the heart. Man has conquered nearly every thing expect death.
