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.
Not understanding the logic doesn't mean it doesn't exist.
We created math and devised a method to ensure that equations can be solved in a way that leads everybody to the same result. If you don't use the rule, you don't get the same answer as someone who does. In this circumstance, yes, you do teach by nailing down a strict rule as it's foundational to the language (math) that we've created.
