short composition Wonders of Modern Science
Introduction: Man always wants to live a better life. He wants better food, clothing, and dwelling. He also likes comfort and entertainment. Science helps man to attain these. As a result, science has developed greatly. Today we are living in an age of science. Day and night, we make use of innumerable discoveries and inventions of science.
Electricity: Electricity is the great power behind many scient inventions. The electric lamp lights up our houses. Radio, television, telegraph, telephone, cinema, tape-recorder, photocopier, VCR, computers and most of the mills and factories are run by electricity. There are also electric trains, printing presses, cookers, irons, fans, sewing machines, etc. run by electricity.
Communication: Science has conquered space and time. We can go from one place to another in a very short time by train, steamer, plane or rocket. Previously people took years to go from one continent to another. But nowadays we take only hours. We have reached the moon. We can now send messages at a great distance in a fraction of a second. We can talk to anybody in any part of the world by telephone. Radio brings songs, music, news, discussions, etc. Television brings pictures also even in color. By FAX, any writing or picture can be sent over great distances very easily. We can do today in hours what was done in days or months before.
Industry: Spinning of yarn, weaving of cloth, and sewing of clothes can be done at a great speed. Food processing, housebuilding, constructing roads and bridges can be done very quickly. Millions of pages can be printed or reproduced in a short time. A calculator can solve a complicated sum in no time.
Medical science: Science has found out the causes of most of the diseases and has discovered many remedies. A deadly disease like TB has been conquered. Cholera has also been brought under control. Smallpox has been eliminated. The XRay and the anti-biotic have been very helpful to man. A cornea transplant, bypass surgery, etc. are marvels of medical science.
Agriculture: Science has increased food production greatly. If we can apply the scientific methods properly there will be no hunger in the world. Tractors, power pumps, fertilizers, high-yielding varieties of crops, and irrigation techniques have revolutionized agriculture.
Conclusion: But science is not an unmixed blessing. Science has also invented guns, bombs, and missiles, battleships and warplanes, chemical weapons, and nuclear warheads. It has caused environmental pollution. We should stop the misuse of science to get its real benefits.
