Mathematics
The first uses of a "goose-egg" sign for zero appear about this time in Cambodia and Sumatra, although the Chinese had long used an empty space as a placeholder and later Mesopotamian numeration also used a sign as a placeholder; it is not clear when zero comes to be understood as a number and not just a placeholder.
