ELI5: Explain Like I'm 5

Myriad year clock

Alright kiddo, imagine you have a really big clock that's as tall as a building! And instead of having just one hour hand and one minute hand, this clock has lots and lots of hands. In fact, it has 10 different hands that each tick at a different speed.

But this isn't just any regular clock that tells you the time. This clock is special because it's designed to work for thousands of years without any maintenance or electricity! Can you believe it?

The clock has a big metal ball that swings back and forth like a pendulum to keep the time steady. And it's powered by the changes in temperature from day to night, so it doesn't need any batteries or cords to keep ticking.

Now, let's talk about the design of the clock. Remember how I said it has 10 different hands? Well, each hand represents a different unit of time - from seconds, minutes, and hours to days, weeks, and even centuries!

The clock has a special mechanism that moves each of these hands at the appropriate speed, so it's always keeping track of time in different units. And the coolest part is that once the clock is set up, it'll work for thousands and thousands of years - long after you and I are gone!

So the Myriad Year Clock is a giant clock that can keep time for thousands of years without any electricity or maintenance. It has 10 different hands that represent different units of time, and it's powered by changes in temperature. Impressive, right?
