This is a very interesting article which speaks of Shivkar Talpade pioneering flight a full 8 years before the Wright brothers did (in 1895). Apparently Shivkar's research was based on Samskrit treatises on vaimAnikashAstra. It would be great if this had been true. I would believe it completely had Stephen Knapp's name not been mentioned.
Stephen Knapp has a web site that is pro-Hindu. But it also claims that Taj Mahal was a Shiva temple with pretty poor proof. Any pattern is dubbed 'vedic'. That is another thing I hate nowadays. People are bringing the Veda to everyday life to the extent that soon we'll have vedic tea, vedic coffee and vedic TV. Why the urge to prefix everything under the sun with vedic?
The veda is supreme for me even if it does not talk about quarks or the distance from the earth to the sun or the string theory. It is like a mother to me even if it calls the sun rising and setting. Because the physical realm is not where the veda rules but in the spiritual. What else can declare in words that words and mind cannot reach it ? "yato vAcho nivartante aprApya manasA saha". That, is the realm of the veda and not something like vedic nuclear science or vedic toothpaste. Study of the veda traditionally and with a shraddhA-strengthened intellect should let us into the secrets of the veda.
What can you say to those who think that the puruSha sUkta has coded the distance between the earth and the sun?
