It’s not science fiction either (for which the author is well known).
this is an excellent study of human ingenuity overcoming challenges before we had modern machinery, no ancient astronauts needed.
A fun read if you are even slightly interested in the engineering behind ’stuff’ we use every day.
Entertaining and non-technical. Unfortunately this is very little on Eastern development, such as China.
It was written in the 60s, so it’s time for an update!
