What is an Astrolabe? Professor Glen Cooper (1001 Inventions)?

An astrolabe is like a super-smart toy that helps people know what time it is or where they are in the sky, just by looking up!

Imagine you have a clock face, but instead of numbers, it has stars and constellations. That’s kind of what an astrolabe looks like. People used it a long time ago to figure out the time, directions, or even the weather, all by watching the sky.

Think about turning a spinning wheel on your toy car, that lets you see different parts of the track. An astrolabe has a similar spinning part called a rete, which shows stars moving across the sky as if it's night time. By matching the stars to where they are in the sky, people could tell what time it was or even find their way when traveling.

Professor Glen Cooper, from 1001 Inventions, is like a star explorer who helps kids learn how ancient people used tools like astrolabes. He shows that these cool gadgets are not just for scientists, they're like the smartphones of old, helping everyone live better with the help of the sky!
