Someone asked a group I was with, just in general discussions, which of the ancient cultures may have contributed the most, to advancements in science, medicine and technology in general? Or as many would agree I am sure it was a 'team effort' since every culture, race etc has brilliant minds at work advancing all of the sciences. Which then, would stand out the most, the Mayans, the Chinese, Persians? So many others to examine the list would be too long. What say those here in USMB?
