The scientist who produces repeatable, provable results or whose explanation makes the most sense in light of the evidence given.
Without that worldview, it could not happen. In fact, that is precisely why none of these big discoveries were made in China, or India. Eastern philosophy does not hold to a rational creator-god, but to chaos and uncertainty.
The Chinese and Indians made discoveries of their own as equally important to the development of human learning. Most of these discoveries were made in the field of early agriculture, but there were important discoveries in metallurgy and most notably, in chemistry. Ever hear of gunpowder?
In fact, those two countries fell by the wayside primarily because they took too much on faith and tradition. They became calcified by orthodoxy, and only now are they coming out of a very long dark age.
You are not getting it. My point was that the big unifying scientific theories (gravity, laws of motion, cosmology) were all made by Christians. Gun powder is a small discovery.
