The first half, "Theory," was all cold mathematics—Ohm’s law curled like sleeping snakes, Kirchhoff’s rules stood as stern as judges, and transistor biasing problems sat like unsolved riddles. The second half, "Practice," was messy. Photographs of oscilloscopes, step-by-step soldering guides, and handwritten notes in the margins from Elara’s old mentor: “A cold joint is a liar’s handshake.”
