Since the dawn of civilization, science or systematic study is behind step-by-step progress to the present position. Science has made a rapid stride in the 20th century. From a pin to rocket, we can see the marvels of science. Today science has become a part and parcel of our existence. The invention of electricity is a landmark in the history of scientific invention. It has brought about a revolutionary change in all spheres of human life. It has given us modern life in true sense of term. With the help of the invention of telephone, telegraph and teleprinters, news and views are communicated from one place to another within a very short time. The radio is of recent invention, yet it has already worked wonders. It has annihilated all distance. Television is one of wonders of science. It has enabled us to see the event, scenes, plays etc. that take place at distance from us. It is the most up-to-date means of communication and mass education.
The invention of rocket is another wonder of science. With the help of it, space travel has been a reality. It has made true the dream of mans’ conquering the moon. Science has done great wonders in the field of medicine and treatment of patients. The invention of penicillin, various vaccines, x-ray, ultra-sonography and other latest methods for diagnosing has done incalculable benefit to man. Science has also made great break through in the field of agriculture. It has replaced our traditional agricultural works by giving us tractors, power pumps, fertilizers, deep tube wells, high yielding varieties of crops. Science has removed the distance of places and saved our time by providing us various speedy vehicles like trains, steamers, motorcars, aero planes etc. These transports have brought the world closer to us.
But to energize these, a lot of under-ground resources are used and pollute the environment by its wastes. The latest miracle of science is computer. It has enabled us to perform any difficult works and calculations most accurately and perfectly in a few seconds. But the greatest wonder of science is the release of the nuclear energy. It has made possible the invention of the atom bomb, the hydrogen bomb and the missiles. All these are being used against mankind. These inventions are considered as the living curse to our life and existence on the earth. But there are unlimited possibilities for nuclear energy to be used for peaceful and constructive purpose. Thus science envelops our existence from head to foot. Wonders are the achievement of science. Let us hope science will be utilized to feed the hunger millions, rehabilitate the shelter less, mitigate the sufferings of the ailing ones and be the saviour of mankind.
