Well, I never confused my d+d for d+id ever! Duh!

I’m an electrical engineer and this went waaaaaay over my head.....

[Red Badger]

Here’s MY layman’s take on it:

Electrons spin.

Some electrons spin, let’s call it - clockwise.
Other electrons spin, lets call it - counter clockwise.

Electrons in ordinary room temperature matter are randomly distributed
and spinning in random patterns.

But, sometimes, electrons that spin is the same direction will ‘stick together’ and sync their spins.

Get enough of these electrons to sync up and they will superconduct.

This seems to happen in ferrous materials more often than in non ferrous materials..................

That led to a discussion of whether d+d might be connected with d+id in a meaningful way

They are related. "d+d" is the old Dungeons and Dragons, for real. "d+id" is the newer Dungeons and Imaginary Dragons. The rules for the latter are rather complex.
