Robert,
A nice list of achievements that I am certain people could add to. (such as the Antikythera mechanism, dated to ~200 BC and is the worlds first computing device that could predict planetary motion, eclipses etc. Alcmaeon of Croton was the first to carry out eye surgery and postulate that human emotions resided in the brain rather than the heart ~ 400 BC)
(only issue I have is your list's highly western-centric emphasis. There are lots of discoveries that can be traced back to other societies and civilisations, including indigenous Australian peoples - the very first major engineering works, is attributed to Australian aboriginals who lived in Western Victoria and us dated to almost 8000 years ago. Also we have the first seismograph invented in China and is about 2000 years old. The ancient Chinese were also fiddling around with magnetism which enabled the first compass to be invented. The Arab world also made great contributions to human advancement and enlightenment)
