There are also electric trains, printing press, cookers, irons, sewing machines etc. run by electricity. Science has conquered space and time. We can go from one place to another place in a very short time by train steamer, plane or rocket. We have reached the moon. We can now send messages to a great distance in a second. We can talk to anybody in any part of the world by mobile phone. Radio brings songs, music, news, discussion etc. Television brings pictures also even in color. By FAX, any writing or picture can be sent over great distance very easily. Internet is yet another wonder of modern science. Spinning of yarn, weaving of cloth and sewing of cloths can be done at a great speed. Food processing, house-building, constructing roads and bridge can be done very quickly. Millions of pages can be printed or reproduced in a short time.
A calculator can solve complicated sum in no time. Science has discovered the causes of most of the diseases and their remedies. A deadly disease like TB has been conquered. Cholera has also been brought under control. Small pox has been eliminated. The X-ray and the antibiotic have been very helpful to man. Cornea transplant, by-pass surgery etc. are marvels of medical science. 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, fertilizer, high-yielding varieties of crops and irrigation techniques have revolutionized agriculture. Image result for Red TerrorBut science is not an unmixed blessing. Science has also invented guns, bombs and missiles, battleships and war planes, chemical weapons and nuclear war heads. To speak the truth science has both blessing and curse.
