Borders
(thelemmy.club)
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules
This is a science community. We use the Dawkins definition of meme.
Borders weren't even loosely defined.
In 49 BC the Rubicon river was a clearly defined border between Cisalpine Gaul and Italy itself. Crossing the river was such a momentus decision that we now have the phrase "Crossing the Rubicon" to mean making a decision that you can't go back on. So, borders have been clearly defined for at least 2000 years.
