You can't start at the transistor level. You'd have to learn about circuit theory first. Besides, the math involved with transistors (even in large-signal analysis) is too disconnected from code to be starting there. It's like saying, "To learn to be a manager, start at the neural level." It's the emergent behaviour that you're really interested in.
