How Electricity Becomes Logic

Your computer does not understand numbers—not even something as simple as five plus seven. Beneath the glass, there are only electrical signals moving through microscopic pathways. Drawing on Milan Patel’s step-by-step explanation, this episode reveals how engineers turn that raw electricity into reliable binary information and build a computer from the ground up. Follow the journey from voltage thresholds and transistors to logic gates, adders, memory, clocks, RAM, and the fetch-decode-execute cycle. Along the way, discover why computers never truly subtract, how electricity can be trapped to create memory, and how writing to a “fake” memory address can illuminate an LED or control a motor. How does a rigid world of ones and zeros reach beyond the processor to sense and change our unpredictable physical world?
