I’m sitting here on a long 12 hour shift with my engineering partner discussing major accomplishments of the modern era. It seems to always go back to magnetism. Magnets are incredible tools, and magnetism is even more incredible, yet we have no universities or trade schools openly diving into educating the populous about their incredible abilities.
Give me your thoughts, why is the entire magnetic field being covered up and overlooked by the modern educational system. Are they afraid we’re going re-discover free energy?
What I could never digest was Hole Flow (in semiconductor theory). I. Just. Can't.
It's bullshit that's why. The way to think about it is it's actually rivers of photons moving around, carrying electrons this way and that.
The engineering works, but the science is lies.
Hole flow is 'apparent'. Holes do NOT flow. Electrons move from ring to ring; when an electron leaves a ring, there is an empty space left (to catch the next electron coming through). Hole flow is nothing more than a tool for people to understand the flow of current in semiconductors, since many people can't seem to figure it out. Go back to vacuum valves (tubes) and look at the current flow through a tube; that is essentially the same as flow through a transistor. Since tubes aren't taught any more, other means have to be used. I grew up on tubes. Then went engineering.
