Computers use binary (0s and 1s) to operate, but the first computer concepts, like Charles Babbage's Analytical Engine, were mechanical, using gears and levers. Ironically, the digital age was envisioned through physical, moving parts. Interestingly, quantum computers are now bringing us full circle, leveraging the physics of subatomic particles to process information in ways that defy classic binary logic, using qubits that can be both 0 and 1 simultaneously.
