and ignorance.It has provided him wonderful medicines to control the diseases which were
fatal once upon a time .Science has also provided the doctor wonderful medical test and
instruments to diagnose the defects of human machinery .Surgery has advanced so much that
eyes, kidneys and heart of one body can be transplanted into another.In case of accidents ,we
can have artificial limbs of plastic to live a normal life.
Scientists have invented machines to increase the production of things of daily use.They

months and years can now be covered in days and hours.The wonderful inventions of
telephone ,telegraph ,television,and radio have further destroyed the barriers of time and
distance between persons and nations .They are co-operating with one another in field of
trade, industry and research .The invention of the printing press has greatly helped.The days
of kings ,barons and cruel rulers have come to an end.We are living in the age of
enlightenment democracy and social justice.Electricity is ,perhaps ,the most important
invention of science.It is being used as source of light,heat and power .As s source of power ,
it is behind the movement of every kind of wheel in the field of agriculture, industry and
transportation.With the help of electric power ,man has succeeded in demolishing mountains,
changing the source of rivers, turning deserts into smiling fields ,etc.air-conditioners and
refrigerators have turned this world into paradise.The discovery of atomic energy has brought
about a revolution in human civilization .It is being used for the production of electric power,
curing of certain diseases like cancer and the improvement of the quality as will as quantity of
agricultural products .In short ,mankind is highly indebted to the scientists for their wonderful
