By the mid-20th century, the gears turned into vacuum tubes and then silicon. The room-sized gave way to the microprocessor, shrinking the power of a thousand mathematicians into a chip smaller than a fingernail.
Blaise didn’t just see a tired man; he saw a problem that could be solved with brass and gears. He began sketching the , a mechanical calculator that used a series of geared wheels to add and subtract. When he finally assembled it, the clicks of the metal teeth represented the first mechanical heartbeat of what we now call "computing." The Universal History of Computing: From the Ab...
Today, we no longer hear the click of Pascal’s gears or the hum of mainframe tubes, but every time you tap a screen, you are echoing a journey that began with a single bead on a wooden frame. We have moved from calculating taxes to simulating universes, all by teaching inanimate matter how to "think." By the mid-20th century, the gears turned into
