Scientists have made used of science for the benefit of man and society.They have used scientific principles,laws and facts to invent and develop machines of different kinds.For example,the motor-car,airplane and railway engine,printing machines,machines used in factories producing things of daily use like match-boxes,cloth,paper,shoes,and so on have been invented by scientists.The radio,television,the CD and DVD player,the telephone and the computer are among the many modern electronic inventions that have made our life modern.
Scientists and doctors have invented and developed medicines that can cure speedily dangerous diseases like typhoid,cholera and tuberculosis.Even animals and birds get the finest medical treatment in modern hospitals.
The technological advances of modern science have revolutionized our life patterns.The electronics industry,started in the early 20th century,has reached unimaginable heights of development.Electronics,besides (in addition to) developing the computer,has caused the perfection of new communications devices that include the radio,television and laser.
Science,however,has also been pt to highly destructive uses.The atom bomb and other nuclear bombs,the different kinds of automatic weapons,bomber planes and warships are some examples of its destructive uses.Now several countries,including our own,possess nuclear weapons.The world powers possess weapons that can wipe out(destroy completely)the entire world in a short time.
If all countries decide to live in peace and accept the authority of the UN,science can be used for peaceful purposes alone.All weapons of mass destruction should then be destroyed.The production of atomic and other dangerous weapons should be banned altogether.Then only can the world enjoy the sweet fruits of science at ease.
