    I like sharing these sorts of things with my kids. People in general don’t realize how important precision is. A lot of people assume because they are able to be loose that there is no value to precision. I believe it is because we are, as a society, precise in these kinds of areas that imprecision can be taken as a luxury further down the line without as much incident.

      Agreed. Considering that we’re measuring things on more minute scales than throughout history, having a precise base unit measurement also allows these derived measurements to be accurate.
