It is has been always a question in my mind why America and Europe is able to develop new and advanced technologies. Why countries in other parts of the world find it difficult to keep in pace with that.We can see that take when ever we see a new discovery or invention most of them will be from a European country or from America. Why not an African or Asian country fails to do this ?. Following can be the reasons 1)What ever they find they do not document it 2)What ever they do they do not measure it.
