Here’s a sharp little slice of history: the word “angle” comes from the Latin “angulus,” meaning “a corner.” But here’s where it gets really interesting—the concept of measuring angles in degrees dates back to the Babylonians, who used a base-60 number system. That’s why a full circle has 360 degrees—it’s a legacy of ancient stargazers and mathematicians!

And for a quirky twist: in nuclear physics, there’s a unit of angle called the “milliradian” (mrad), often used in ballistics and scopes. It’s so precise that one mrad at 1,000 meters equals exactly one meter—perfect for sharpshooters and engineers alike.
