Knowledge is Power. While the word "power" has all along been associated with muscular strength, the word "knowledge " is connected with the mind. The two words do not seem to have any connection whatsoever. However, today the word power has undergone a tremendous transformation. Today it is recognized that the pen is mightier than the sword. A brainy and not a muscular person is considered important and a more useful citizen of the society. The present society respects psychologists, philosophers and literary men who make great contributions for mankind. A scientist, though physically weak or even wreck can cause a destruction which hundreds of able- bodies men cannot even dream of. Whatever comfort and luxuries we enjoy today are the direct result of study and inventions of men of knowledge.
