Welcome to c/science_memes @ Mander.xyz!
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.

First of all, yes - Electromagnetics is a branch of physics. James Maxwell was a physicist.
Second - Electromagnetics is not electronics. Electronics is a field that applies electricity and magnetism to make useful things.
Yeah but Electromagnetics is the DEEP magic behind electronics.
You could, if you wanted, use quantum mechanics and electromagnetic field theory to do circuit design. But unless you're building quantum computers or doing simple circuit analysis and wanted a real challenge applying Kirchhoff's Laws, there's no need.
So you can use the simplified electronics model where the current (and therefore primary charge carriers) is positive.

So then Bridge Diodes are not Physics.
Sorry to upset the analogue stereo repair shop but you're not exactly Stephen Hawkings, okay?
I feel like "How dare you compare me to a paraplegic" sounded better in your head.
