The modern age is the age of science. The influence of science can be seen in the everyday walk of life. Science has provided us with many wonders. If our ancestors happen to visit the modern world they will not be able to recognise it. The world today has completely changed. Its complexion has especially changed during the last three hundred years or so, In a way the world has become a fairy-land as compared with the ancient times.
The contribution of science is seen in our everyday life. It has increased the happiness and comforts of human beings greatly. It has made our domestic life very easy. Now the housewife does not have to work very hard. With the help of the latest cooking devices, meals can be cooked quickly. Food can also be preserved for a long time in the refrigerator. The clothes can be washed in the washing machines. Thus a housewife can enjoy more leisure and can save a lot of her time.
Science has also given us fans and air conditioners. With the help of these, we can save ourselves from the scorching heat of the sun in summer and keep the rooms warm with the help of room heaters in the winter. Thus our houses are lighted, cooled and heated with the latest scientific gadgets. Electricity is really a great wonder of science. All types of machinery can be run with its help. Rooms can be lighted, water can be lifted and trains can be run with electricity.
Science in everyday life has also made travel very comfortable. There are so many modes of travel available to us. We can travel by railway trains, motor cars, buses or steamers. Aeroplanes have brought the different countries quite close to each other. Within a few hours, we can travel thousands of miles and reach different corners of the world. Thus all the nations of the world have become one family. The world has really become much smaller. The bicycles, motorcycles, scooters, ships and the jumbo jet of the twentieth century are the beautiful gifts of science.
Science has also revolutionized the methods of communications. We can talk with our friends and relatives thousands of miles away from us with the help of modern scientific devices like telephone and wireless telegraphy. We can also send messages to different parts of our country and even to all corners of the world within a few hours. Through radio broadcasts, messages can be conveyed to all parts of the world. On the television, we cannot only hear the voices but can also see what is being telecast. Broadcasts made from England and America can be heard all over the world.
Science has also helped mankind to fight against dangerous diseases. It has lessened the sufferings and miseries of man. Many diseases which were incurable in the past can be cured now. It has also worked wonders in the field of surgery. Operations can be carried out even on delicate parts of the body like brain and heart. Even transplantation of hearts and kidneys has become possible. With the help of X-rays, hidden diseases in the body of man can be diagnosed easily. It is a fact that science has given eyes to the blind. The lame has been provided with legs and ears have been provided to the deaf. Epidemics like cholera, small-pox, malaria, etc. can be controlled by inoculating the people against these diseases. Science has thus given a new lease of life to the diseased and the injured.
Science has also reduced the burden of the workers. The arduous and difficult jobs can be done by machines. It has also taken over the dirtiest jobs from man. With the help of machines and instruments, huge weights can be lifted and goods produced on a very large scale. It has also provided many sources of entertainment to a man like cinema, radio, television, books, etc.
Science has helped in increasing agricultural production through scientific methods of farming like better seeds, fertilizers, better implements, etc. It is with the help of science that man has reached the moon and now he is probing other planets like Mars and Venus.
But this is only one side of the picture. If in certain respects it has proved a blessing it has also acted as a curse in certain fields. It has produced highly destructive weapons like atom bombs and hydrogen bombs which can destroy the world in no time. During the Second World War lacs of people were killed in Hiroshima and Nagasaki when the U.S.A. dropped atom bombs on them in 1945.
Science has produced many deadlier weapons and made wars very horrible. It is a Third World War takes place in the near future, it might destroy all life on the earth as it will be a nuclear war. The man was never so insecure as he is today.
But in reality, there is nothing wrong with science. It is up to the man to decide whether he wants to use it for peaceful purposes or for destructive purposes. Science is such a knowledge which can be turned both into a blessing and curse. But a man should always use science for the promotion of peace and happiness of mankind. It should never be used for war or destructive purposes.
