I would take issue with some of the inventions as being significant. Given 50 that is inevitable.

However there is an Oxford Professor who was on UK TV only this week proving that the Hanging Gardens of Babylon were not in Babylon but in Nineveh (present-day Mosul). The significance ofd this is that she was quite clear that they used the Archimedian Spiral to lift water that had already come 700 Km from the mountains. So the date for that invention would be at least 500 years earlier. Given that the Greeks were the ones listing the 7 wonders of the ancient world and visited them like modern-day tourists - maybe Archimedes was one such.
