We live in an age of science. Science has entered in every field of our life. It has added many comforts to our life. The impossibilities of the past have been made possible. New miracles are happening everyday. It has given man a new sense of confidence and power. Man has conquered the forces of nature. He is not afraid of the wild animals tempests and floods. It has helped man to explore the hidden treasures in the earth. Man has now learnt to land on moon. He is in search of new worlds. A great writer Emerson says “Science surpasses the old miracles of mythology.
Science has brought a revolution in the matters of transportation and communication. It has shortened the distances. In the past, travelling was a difficult and dangerous matter. It took weeks and months to reach from one place to another. People bade farewell to their relatives and friends with a heavy heart while they set out on a journey. Now the days have gone. We can now travel from one part of the world to the other in a few hours. There are rocket planes that travel at the speed of seven or eight hundred miles per hour. They travel faster than sound.
Telephone, wireless, radio and television are wonderful inventions of science. They connect us with the world within a twinkling of an eye. The radio and TV are the most powerful means of information and education for us. They make a record of everything which happens in the world TV with its plays, entertaining features and educational programmes enlighten and delight our minds.

Wireless has brought the countries close together. The world has shrunk in size. Science has established and strengthened the bonds of friendship and love between the people of different countries. It is no doubt a great service of science.
Electricity is perhaps the most wonderful invention of sence. It is used as a source of light, heat and power. With the help of power, we can now change the course of rivers, demolish the mountains and cultivate our barren lands. Without it, the whole progress of industry would come to a standstill. Had it not been invented, the entire world would have plunged into darkness. It moves trains and tramways. It heats our rooms in winter and cools them in summer. It cools our food and irons our clothes.
It has also done wonders in the world of medicine. Treatment by X-ray and radium is one of the greatest wonders of science. Difficult surgical operations have become a routine matter Vaccination has made small pox a thing of the past. Many other diseases like cholera plague and TB have been fully controlled. Quinine has finished malaria. It has also made our social life easy and comfortable. It has given us many ways of recreation. The cinema, radio and television have made us cheerful and comfortable.
Science has made us open minded and rational. We analyse everything before we believe it. We do not have faith in ghosts and spirits. Now-a-days science has made us practical minded.
