Recently, I was mindblown to read about electron viscosity. A colleague was asking about fluid dynamics, relating to air flowing through a tube with a cylinder in the middle. The equations looked very similar to those used for coaxial cables, and someone else had commented that the physics models are in fact quite similar. I can't find the StackExchange link right now, but here's another article about electron viscosity, "negative resistance, electron whirlpools and superballistic flow." https://www.manchester.ac.uk/discover/news/graphene-reveals-electrons-move-like-viscous-liquids/ https://www.manchester.ac.uk/discover/news/graphene-reveals-...
