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.
Right, those wouldn't be holes.
You seem to not be getting that words can have multiple (even if related) meanings. When some science or other discipline takes a common word and defines it really precisely for their purposes, that doesn't change the definition of the common word for all usages and mandate that all lay people use it only with that discipline's more precise definition.
Better precision leads to better communication.
Quite true. It is also important to know the limits of the precision you are going to be getting.
