Hey,
Who knows? People has to try out to see it works. Most people are experimentalists you see? (I tried being a theoretician, but I am too dumb.)
You know people used to use Germanium Transistors in Missile Guidance Systems? Germanium transistors break down at high temperature and missiles it's really hot inside them chasis; burning fuel you see? (You might noticed it building Germanium [Diode] Radio.) I hear that one of Missiles using Germanium Transistor Guidance System tracked perfectly its launching pad! (Came right back to the launcher)
Me? Well I had to experimentally prove to myself that touching soldering iron is a no-no. I have scars to prove it! (Just another day I wired LM337 in the opposite direction. I am just silly.)
