Science has changed the face of the world. It has also revolutionized the life of man. Man can now live a longer and more comfortable life because of the progress of science. Man has conquered Nature with the help of science.
The wonders of Science have contributed to the comforts and pleasures of man. Man can be comfortable anywhere on the surface of the earth. Air- conditioning can keep him cool at the Equator. Central heating makes it possible for him to keep warm at the Poles. He has become independent of the climate. Labour- saving gadgets have lightened the burden of house work for the housewife. Science has also added to our pleasure. We can turn on the radio or TV and entertain ourselves at home. If we wish for outdoor entertainment we can go and see a film or do a variety of other things.
Electricity is one of the wonders of Science. Without it we would not have had electric lights, fans, refrigerators and all the labour-saving devices in the home. We also have wonderful means of travel. Cars and buses are very common. Electric trains carry us across the land with great speed. Jet planes go like a flash across the sky. In no time, we can be in another continent. Thus speedy travel is possible only on account of the wonders of science. Electricity also enables us to use elevators and escalators that save us the trouble of going up and down flights of stairs.
Science has also provided us with spectacles and contact lenses artificial limbs, fountain pens, type-writers and mechanical brains or computers, aren't all these the wonders of science ?
It is a wonder that science has conquered deadly diseases, made man healthier and lengthened the span of human life. There is now a cure for practically every fatal disease that used to take a heavy toll of human life in the past. Not only this still more wonderful is the fact that worn out organs like the human heart and kidneys can be replaced by transplants. In the future, perhaps, scientists might be able to make man live forever.
With the help of science, man has even reached the moon. Soon he will be visiting other planets too. There is no limit to the wonders of science. Scientists are coming out with new inventions and wonders every now and then.
The atom bomb and nuclear weapons are also wonders of science. As these can cause much destruction, it would be better for men to make constructive use of the wonders of science. Then only will they add to the happiness and prosperity of mankind.
