I agree that the History cannot be changed, but the Britishers forced Indian to follow their culture and they want to get credit of great inventions done by Indians. One such invention was 'flying machine'.
Indian contributions were in ancient world and rightly they should be appreciated. But when it comes to modern world we have to accept the fact that our contribution has only been population. Why it happened needs to be researched and understood.Merely blaming Muslims and British is skirting the issue. Why did not the fantastic contributions make us strong instead we became weak and got colonized.
