bidhan, my point exactly, all these inventions u listed are just modifications of white's inventions. Thats what i meant when i said, there are some non whites who know everything within the circle but only white can think outside of circle. I am talking about person who invented electricity, not a damn resistor, i am talking about someone who invented engine not a damn truck, someone who iinvented TV not a damn survailance, someone who invented Radio not an advanced cd palyer. I dont deny the fact that there are major intellectuals that are non whites who have enhanced in great on what whites have created. I am talking about creativity,originality, thinking outside of the box type.
