A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

A 11.8 and a 13 in parallel is 6.1854838709677 which is 0.01% off from that resistance. Of course even using matched 1% would screw you as soon as someone opens the door.
You could get exactly 6.1854838709677 for an instantaneous moment by heating up a 6ohm resistor.
So you just need to figure out the precise amount of prewarming, then subsequently cooling in coordination with the circuit's load to make sure it stays at the right temperature?
