The Place of Science in the Modern World (300 Words)
Scientists have made use 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 motorcar, the 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 put 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 use. 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.

The wonders of science that have benefited human beings are almost countless. Scientists are now working to control the environment by or causing rainfall and shifting hurricanes (violent wind-storms) from one place to another. New sources of energy are being developed to check the fast depletion (using up) of regular fuels like oil and gas. In this connection, the use of atomic energy for the generation (production) of electricity and working of ship and plane engines is notable.
Science has transformed transportation magically as now the supersonic jet can take the man to the farthest end of the world in hours, and the rocket can take him to the moon and even beyond. The fastmoving submarine can pierce through the seawater under the surface to long distances, with the help of the radar, for scientific and business purposes.
Laser technology, based on the control of beams of light for special purposes, is used in industry and construction. It is used for cutting and boring metals and other materials. In medicine, it is used in surgical operations. The use of laser beams in sound transmission is becoming common.
Satellite communication and the Internet have made the world a global village. The rockets fired by the big powers collect useful data (regular information) in space and on other planets and heavenly bodies. This data is used for making arrangements for future manned space travel and stay in other parts of the universe.
Scientists have also put science to harmful or destructive uses. For example, they have prepared harmful drugs and intoxicants. They have invented and developed all kinds of small and big arms and weapons like the rifle, machines gun, the tank and the missile. They have prepared bomber and fighter planes, warships and submarines. They have prepared bombs giving out poisonous gases and setting huge areas on fire. Then they have made the atomic, hydrogeri, cobalt, nitrogen and neutron bombs which can destroy whole cities, countries and civilizations in minutes.
In fact, science teaches us to work without prejudice. Scientists in all countries use the same scientific formulas, laws, and results. They should, therefore, work together for the advancement of humankind. They should not, in any case, prepare weapons of mass destruction. Science is supreme knowledge, and it should be used for the supreme good of all human beings.
