A turning point came when Ana volunteered for a lab project repairing a donated electric bicycle. The motor refused to engage consistently; the controller’s output waved unpredictably on the oscilloscope. Classmates wanted to swap parts, assuming the board was faulty. Ana, with Ohanian tucked into her backpack, walked the team through how to model the motor’s coil inductance and the controller’s switching as idealized circuits first, then add real-world imperfections. They traced an intermittent grounding problem to a frayed connector that, under vibration, altered the circuit’s boundary conditions — exactly the kind of “small thing, big effect” that the book’s appendices emphasized.
