This might be a dumb question to some. I've been reading a lot about
electronics, but never find a good piece of text that properly tells
about how to design a PRACTICAL circuit. I've seen some basic examples
such as connecting a LED, resistor, and a battery and using Ohm's Law
to determine to right resistance, but that's about it. I never have
heard why an engineer explain how they built their own circuits and
why they chose these parts. We'll anyway, I'm just wondering how
people are able to design.

All circuit design, as everything else, can be resolved to the Darwinian
Algorithm. That is, a process that utilises, Replication, Random
Variation, and Selection.


I suppose "everything else" includes mathematical and scientific
theories, poems, novels, musical themes, architectural designs,
computer architectures, and, well, everything else.

Keep copying those circuits; I'm glad I use a better algorithm.
