I agree with your suggestions. Germans learnt a lot from the Sanskrit manuscripts that they took from India and even today it is the only place where one can do Ph.D. in Sanskrit!The knowledge about rocketry in which Germans first made rockets was acquired through some ancient Sanskrit manuscripts.There is also a record od a brahmin in Mumbai who manufactured a plane and flew it on chowpaty an art he learnt from one of the old scripts in sanskrit. It also happens to be the most computer friendly language in the world!
