"Tools" come with pre-measured amounts or distances already printed on them

Richard Sudo Thursday, September 3, 2015 9:59:45 AM CT 00:19:e3:4a:d2:21

People had to develop ways of measuringusing simple geometric concepts

Richard Sudo Thursday, September 3, 2015 9:59:45 AM CT 00:19:e3:4a:d2:21

How did people learn to accurately measurethings before specialized "tools" were available?
