The wonder of modern science
Introduction: Man always wants to live a better life. He wants
better food, clothing, and dwelling. He also likes comfort and
entertainment. Science helps man to attain these. As a result,
science has developed greatly. Today we are living in an age of
science. Day and night, we make sus of innumerable discoveries
and inventions of science.
Electricity: Electricity is the great power behind many scientific
inventions. The electric lamp lights up our houses. Radio,
television, telegraph, telephone, cinema, tape-recorder, photo-
copier, VCR, computers, and most of the mills and factories are
run by electricity. There are also electric, printing
presses, cookers, irons, fans, sewing machines, etc. run by
Communication: Science has conquered space-time. We
can go from one place to another in a very short time by train,
steamer, plane or rocket. Previously people took years to go from
one continent to another. But nowadays we take only hours. We
have reached the moon. We can now send messages at a great
distance in a fraction of a second. We can talk to anybody in
any part of the world by telephone. Radio brings songs, music,
news, discussions, etc. Television brings pictures also even in
color. By FAX, any writing or picture can be sent over great
distances very easily. We can do today in hours what was done
in days or months before.
Industry: Spinning of yarn, weaving of cloth, and sewing of
clothes can be done at a great speed. Food processing, house-
building, constructing roads and bridges can be done very
quickly. Millions of pages can be printed or reproduced in a
short time. A calculator can solve a complicated sum in no time.
Medical science: Science has found out the causes of most of
the diseases and has discovered many remedies. A deadly
disease like TB has been conquered. Cholera has also been
brought under control. Smallpox has been eliminated. The X-
Ray and the anti-biotic have been very helpful to man. A cornea
transplant, bypass surgery, etc. are marvels of medical science.
Agriculture: 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 fertilizers, high-
yielding varieties of crops and irrigation techniques have
Conclusion: But science is not an unmixed blessing. Science
has also invented guns, bombs and missiles, battleships and
warplanes, chemical weapons, and nuclear warheads.
Is has caused environmental pollution. We should stop the
misuse of science to get its real benefits.
