This is the age of science and technology, which has created wonders. Once in the past our ancestors would have regarded the scientific discoveries as miracles, but now they have become reality and we are reaping the fruits of the wonderful innovations of science. We have become acquainted with such amazing things,which our ancestors could not have even imagined. Life has been made much easier by the scientific discoveries. We have learnt from the Ramaya that Rava, the king of Lanka, had a chariot which flew across the air and after abducting Sita he carried her off to his kingdom in his flying chariot. People thought that Rava’s flying chariot was nothing but an imagition of the author, the great poet and sage Rishi Valmiki. The people in the ancient era possibly could not have even imagined that one day their descendents would fly across the air just like the king of Lanka, in aeroplane, a modern version for the flying chariot. This is one of the wonderful contributions of science to mankind.
