The Bluetooth Symbol Is Secretly a Viking King
Look at the Bluetooth symbol on your earbuds, your speaker, your car dashboard. That little jagged blue icon you see a dozen times a day. You have probably never given it a second thought.

Where the Word ‘Robot’ Actually Comes From
You say the word robot without a second thought. Factory arms, vacuum discs, sci-fi androids, the little machine that mows a lawn.

Who Wrote the First Computer Program? (In 1843)
Picture writing software today, but for a machine that doesn’t exist yet. No screen, no keyboard, no processor humming under your desk. Just a design on paper and a hunch that it could work.

The QWERTY Keyboard Was Not Designed to Slow You Down
You have almost certainly heard the story. The QWERTY keyboard, the one you are probably typing on right now, was supposedly designed to slow typists down.

Why Is It Called a Computer Mouse? The 1964 Origin Story

Your Power Button Is Secretly a 1 and a 0
Look down at almost any device you own and you will find the same little symbol stamped near the power button. A circle with a small line poking through the top. You have pressed it thousands of times without ever wondering what it means. Here is the fun part. That symbol is not random art.…
