And we need to work on it.

My big advice for all of us, whenever I talk to my friends about, or anybody, my students as well, is that you shouldn't, if you're labeling yourself as part of a team,

I'm like, I'm part of this group and I'm part of that group and you only believe what they say, then you're already like up against it, right?

You should, you have to, we're not part of teams.

We're all part of the group.

We're all working together.

So this was a, I teach a course called history of astronomy and we do the entire history of astronomy.

It's mostly from a European perspective, unfortunately, but it does a decent job of covering the story from early, early humans, 10,000 years ago or so up until today.

And one of the big parts we focus on is ancient Greek astronomy and like

600 BCE to about 200 CE or so, that ancient Greek into ancient Rome.

And one of the most notable people during that time was this guy named Hipparchus.

Hipparchus was apparently one of the best observers on the planet.

He would go out, he would observe the sky, and he made very meticulously drawn maps, according to lore.

Now, his original maps of the sky have been lost, but they were copied and changed and added to by other philosophers of the time, Ptolemy and Al-Sufi, to name a couple.

But the original maps of Hipparchus have apparently not been seen.

So enter this group.

What they did is they, what people used to do is they used to reuse parchment paper, parchment, you know, if nobody's been using it for a while, they would like use some chemicals, they would wash off all the ink and then they would write over top of it.

And so they've been, this group has been

looking at all these old ancient parchments and finding and seeing that there's, there is, you can see it with your eyes that there's stuff smudged on there from like the last time it was used.

But how do you like get the information out?
