Something worth repeating is that transistors are a direct application of quantum mechanics. Quantum physics isn't a metaphysical thing about half dead cats and working only on a few ultra cold atoms. If you want to explain how a piece of silicium can be conductive or insulating depending on it's polarisation you need... Quantum physics.
