Essay:Atomic Energy and Scientific Progress

Atom is Greek word which means a thing that cannot be cut and broken.It is the smallest
particle of matter.It is no longer undivided and broken.The scientists have broken it into
further smallest particles.They are called electrons ,protons and neutrons.They release great
power and energy.It was the great scientist Einstein who began to work on theory of
producing energy from atom in 1905.He explained many things.First, he showed that matter
and energy are different forms of the same thing.In other words,matter can be converted into
energy and vice versa.Second; a small amount of matter produced a great amount of energy.
The discovery of atomic energy is one of the wonders of the modern science.

The scientists first of all used it for destructive purpose.They prepared atomic 
bombs, hydrogen and cobalt bombs which could destroy cities and towns within a twinkling
of an eye .It was in 1945 ,that a single atom bomb destroyed Hiroshima and Nagasaki .It killed
thousands of men and women and destroyed vast areas of land.Now all the big powers
possess much more atomic and dangerous hydrogen bombs.They can raze the world
to ground if they are clearly used.

Atomic energy can also be used for the welfare of mankind.The scientists in U.S.A ,
England, Canada and Germany are at work for peaceful use of nuclear energy.An atom for
peace conference was held at Geneva to think over the use of Nuclear Energy.The U.S.A has
already started to use this energy to propel submarines and space rockets.The Russians
have also harnessed it for space travel.At present, electricity is produced form the atomic
energy in advanced countries like U.S.A , Russia and Britain .Our scientists are also trying to
produce electricity from atomic energy.The scientists are also trying to produce electricity
form atomic energy.The scientists are also trying to find out ways of using atomic powers as
fuel in ships aeroplanes,, motor cars etc. At present atomic reactors for boiling water exist in
different countries.

Atomic energy is safely used to conquer many fatal diseases.Radium is used in the
treatment of cancer.Tadio-therapy is an important branch of medical science.It is used to
destroy the over grown cells of our body.The Isotopes of sodium, potassium , bromine and
iodine are used to known origin of disease.Thus atomic energy is fo immense help to alleviate
human sufferings.

Nuclear energy has also brought a revolution in the field of industry.Petrol and coal are
well known sources of energy and power.The supply of these two sources of power is coming
to an end.The world is in search of another source of power.It is the nuclear energy.
Electronic machines and computers are being use in our industry.They are used in the
Plastic, glass ,paper textile ,rubber and cement industry .Atomic energy is also a great help in
agriculture.The barren lands can be tiled into smiling fields with the help of computerizes
tractors and machines.Crops can be ripened within a very short time .The yield crops per
acre can also be multiplied .In this way the scientists are trying to solve the shortage of food
problems .We can say that atomic energy can be used with full advantage for the welfare of
mankind
