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.

The actual method for calibrating exact resistor values involves starting with a lower resistance and etching away parts of it with a laser to get to the exact value you want. You probably still couldn't get as many decimal places as OP tho
And then in a week it drifts into a different value and you have to calibrate it again.
And that's assuming your room temperature is controlled for all experiments.
And that's also assuming the current going through it is 0 so it is always exactly at room temperature.
Virgin theoretical physicist vs Chad experimental physicist goes brrr
For really sensitive applications like voltage references, they actually build a little enclosure around the part with a built in heater to keep it at a constant calibrated temperature. The boards also often have cutouts to reduce thermal transfer and things like the board flexing causing stress to the part.
The resistor itself won't really drift at a constant temperature, especially in a sealed environment where condensation, corrosion, and dust aren't a factor.
Though of course real programmers use vim
Emacs or die
Emacs means die. Vim4lyfe
I just raw dog it in Pico most of the time.
How?? Muscle memory fails me every time
I only ever used it in command lines. And use other simple IDEs (Textmate and a bunch of custom bundles on a Mac…) occasionally Atom based IDEs for some embedded electronics too, but only really as a hobby.
As a layperson, what happens if crumbs from my sandwich fall all over your chad experiment setup?
