But knowing the evolution is very helpful to me.
When you consider the relationship of the behavior of electrons and “electron holes” in semiconductors and compare it to aligning magnetic fields… it really helps in comprehending “how it works” from several different viewpoints.
electrons and electron holes analogize to balls in cups moving around and aligning magnetic fields analogizes to changing water flow direction.
Yet even within semiconductor lingo, the “source/drain” metaphor remains. Whole thing is fascinating honestly.
