I am just trying to seek an answer to a question which I have been asking my teachers since I was a kid and till now no body has given me a satisfactory answer.I don't intend to make a derogatory comparison . Incase this question is beyond the scope / spectrum of the site , then may I please request very humbly for the forum member to give me some relevant links which precisesly and explicitly explain the above facts. Thanks and regards
