Man tries to find out the way to fulfill his needs with the help of science. Science is systematic knowledge and the man who uses this knowledge is called a scientist. We travel to a distant place by train. An engine, either a stream of diesel engine, pulls the train. The steam engine was invented by James Watt, a great scientist. Now, these streams and diesel engines have been replaced by electric engines. We can fly in the air like Birds. We can reach any part of the word within a few hours. Do you know who invented the aeroplane? The Wright brothers invented airplanes and made our long journeys fast and comfortable.

Scientists have made impossible tasks possible. This best world has been changed into a global village, because of science. But unfortunately, inspite of all these, science has not changed the basic attitude toward the problems of our lives.
