And they're like, no, I mean the stick.

Right.

They said you can get canceled for that.

So if you're like, well, that sounds a lot like a sundial, you're right.

The thing that sticks up for the sundial is a gnomon.

There's another version of it that's even earlier than the sundial, it seems, from ancient Egypt called the shadow clock.

Yeah.

It's actually really hard to describe.

It's much easier to just go look up.

But imagine a capital T laying flat on its back on the ground, and it's raised its head and neck up to look at its feet.

That's essentially... That's kind of perfect, actually.

Thank you.

I really thought about that one for a while, I have to admit.

But the shadow that that crossbar, the top of the T, casts on the rest of the T over the day is demarcated.

So you can track six hours a day as the sun is rising in the east, and then you turn it around at noon, and then you track the next six hours as the sun is setting in the west.

Pretty spectacular considering that's close to 3,000 years old.

Yeah, for sure.

Uh, for that descriptor, did it help you that you were laying flat on your back, uh, with your neck raised up looking at your feet?

Yeah.

Sadly, I have to admit that I, I had to go lay down and figure it out myself.
