Are Asians Smarter?

Finding a good job means you have to be smart. You won't get hired to do something that's already invented or could be done with a computer.

I don't really get what you're trying to say in the lower paragraph. Are you stating that probability is useless? Compared to astronomy, probability has a physical use at a much lower level than astronomy has.
To the astronomy-thing: Newton, Kepler and Galilei. The calendar was invented everywhere, and was not special for the Chinese only.

Your point? Finding a good job still won't mean you'll become famous mathematician/scientist.

You said pascal got credited because he find an important use of his discovery: probability. Probability is not important in pascal's time.
While in ancient China, astronomy was very important, and the mathematics they discovered are to be used in astronomy.
