Whenever I write documentation, my first step is to explain how silicon can be used as a transistor.
I used to think it was a struggle to walk the user through introductory EM physics.
But, it turns out that was a walk in the park compared to explaining how to acquire and isolate the dopants, not to mention building up the pure silicon wafers.
Yeah well I produce home grown silicon in super novae.
