Science has also made travel very comfortable.
There are so many modes of travel available to us. We can travel by railway
trains, motor cars, buses or steamers. Aero planes have brought the different countries
quite close to each other. Within a few hours we can travel thousands of mile
and reach different corners of the world. Thus all the nations of the world
have become one family. The world has really become much smaller. The bicycles,
motorcycles, scooters, shops and the jumbo jets of the twentieth century are
the beautiful gifts of science.
Science has also revolutionized the methods of
communications. We can talk with our friends and relatives thousands of miles
away from us with the help of modern scientific devices like telephone,
wireless telegraphy and internet. We can also send message to different parts
of our country and even to all corners of the world within a few hours. Through
radio broadcasts messages can be conveyed to all parts of the world. On the
television we cannot only hear the voices but can also see what is being
telecast. Broadcasts made from England and America can be heard all over the
world.
Science has also helped mankind to fight against dangerous
diseases. It has lessened the sufferings and miseries of man. Many diseases
which were incurable in the past can be cured now. It has also worked wonders
in the field of surgery. Operations can be carried out even on delicate parts
of the body like brain and heart. Even transplantation of hearts and kidneys
has become possible. With the help of X-rays hidden disease in the body of man
can be diagnosed easily. It is a fact that science has given eye to the blind.
The lame has been provided with legs. Science has thus given a new ease of life
to the diseased and the injured.
Science has also reduced the burden of the workers.
The taken Over and the difficult jobs can be done by machines. It has also over
the dirtiest jobs from man. With the help of machines and instruments huge
weights can be lifted and goods produced on a very large scale. It has also
provided many sources of entertainment to a like cinema, radio, television, and
books, etc.
Science has helped in increasing the agricultural
production trough scientific methods of farming like better seeds, fertilizers,
better implements, etc. It is with the help of science that man has reached the
moon and now he is probing other planets like Mars and Venus.
But this is only one side of the picture. If in
certain respects it is proved as a blessing it has also acted as a curse in
certain fields. It produced highly destructive weapons like atom bombs and hydrogen
bombs which can destroy the world in no time. During the world war millions of
people were killed in Hiroshima and Nagasaki, when U.S.A. dropped atom bombs on
them in 1945.
Science has produced many deadlier weapons and made
wars horrible. If a Third World War takes place in the near future, it might
destroy all life on the earth as it will be a nuclear war man was never as
insecure as he is today.
But in reality there is nothing wrong with
science, it is up to the man to decide whether he wants to use it for peaceful
purses or for destructive purposes. Science is such a knowledge which can be turned
both into a blessing and curse. But man should always use science the promotion
of peace and happiness of mankind. It should never be used for war or
destructive purposes.
