Science is a boon to mankind. The growth of science has given us a lot of advantages. They are in the fields of lighting, transports, kitchen wares, running factories, medicine, agriculture etc. The fans, the electric lights, the electric trains and the air flights radio, television, mixie, grinder, electric ovens, gas stoves etc., are of great use to us. They are useful but to some extent cheap.
In the field of medicine today we get a lot of powerful life-saving drugs. The costly modern hospital equipments that we make use are of X-ray, scanning. Surgical machines are the modern gift of science and technology. In the field of agriculture too, we use modern farm equipments like tractor, harvesting machines. Pesticides and manures have come to help the farmers. They make the best use of them and grow more and more corns. The green revolution is the result of modern science. The computer and modern electronic goods help us a lot. These have made our life happier and more comfortable.
Science is a bad master. Some make use of the growth of Science for their own selfish ends. Especially the politicians muddle with Science and with the help of scientists manufacture dangerous bombs. We had enough experience of such bomb explosions in Nagasaki and Hiroshima in Japan. So we must act and thus convert it as our good servant and not bad master.
