Ten Events

Useful set of 10 dates to remember. An interesting observation is that it seems to show us making progress(?) on an exponential scale. Or is that just human ego. maybe events like "humans travelling to the moon" are significant to just our race. In the grand scheme of things its still the same pace. Who else in this universe cares that humans took 2 million years to come up with the printing press and then just a couple of thousand more years to put man into space.
