I don't get it. Is "tree" some kind of notation?

[-] salarua@sopuli.xyz 99 points 1 week ago

TREE is an extremely fast-growing function in set theory. TREE(1) equals 1, TREE(2) equals 3, and TREE(3) equals a number so large that its lower bound easily dwarfs Graham's Number.

its lower bound easily dwarfs Graham's Number.

Yo you don’t gotta throw shade on Grahams number like that, it’s doing its best

[-] Hupf@feddit.org 2 points 1 week ago

Well, that escalated quickly.

Yes, TREE(3) is larger than a googolplex or even graham’s number.

[-] koper@feddit.nl 28 points 1 week ago

Why do I always feel like I need a PhD to understand even the first paragraph of Wikipedia articles about math. Is that just me?

[-] match@pawb.social 18 points 1 week ago

yeah where's the Simple English Wikipedia article for Graham's number

[-] Klear@lemmy.world 9 points 1 week ago

Graham’s number is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to Graham’s number.

[-] LostXOR@fedia.io 7 points 1 week ago

Go get your PhD and write one yourself!

[-] Gork@lemm.ee 23 points 1 week ago

What about our friend TREE(Graham's Number)

[-] teft@lemmy.world 29 points 1 week ago

Numberphile did a video on TREE(g~64~) so you gotta go bigger.

That article is not comprehensible to most people

Here is a Numberphile video that describes how large a number we are talking.

[-] bdonvr@thelemmy.club 5 points 1 week ago

Thanks, I get it now!

Math meme ... it's a math meme!

[-] yum@lemmy.eco.br 3 points 1 week ago

Is math related to science?

[-] Droechai@lemm.ee 5 points 1 week ago

I don't think so, science deals with reality and math are just floating around

man hes gone have to do a lot of walking again... Offtopic: The funny thing is TREE(3) is an absurdly long distance, independent of the physical unit. Even TREE(3) times the planck length is unimaginable long, as the ratio between a meter and the planck length is absolutely neglectable against such super large numbers.

[-] LostXOR@fedia.io 22 points 1 week ago

It's so large that the number of digits it has is too large to represent, and the number of digits in that number is too large to represent, and so on for a number of times that is also far too large to represent.

[-] trolololol@lemmy.world 3 points 1 week ago

So the only way it's worth taking about it is in memes right? Right?

[-] Sibshops@lemm.ee 22 points 1 week ago

Let's say you have to move to the infinite room. How can someone check out of the hotel?

[-] wise_pancake@lemmy.ca 34 points 1 week ago

There is no infinity room, but there is an infinity pool

[-] Tai@lemm.ee 15 points 1 week ago

You can check out any time you like

[-] Sibshops@lemm.ee 8 points 1 week ago

The only issue is that if I have to travel to an infinite distance to the lobby, I'll never check out.

[-] LostXOR@fedia.io 22 points 1 week ago

Don't worry, you can never be put in a room with an infinite number, only an arbitrarily large one. That's the idea of the hotel; it has an infinite number of rooms, but every room has a finite number, since you can count forever without reaching infinity.

[-] Sibshops@lemm.ee 6 points 1 week ago* (last edited 1 week ago)

Whew, I was worried as the infinite passanger on that bus that I'd be put into an infinite room.

[-] Klear@sh.itjust.works 7 points 1 week ago

Just move halfway to the lobby, then again halfway to the lobby and...

...shit.

[-] mathemachristian@hexbear.net 2 points 1 week ago

There is no infinite room though?? What?

[-] woodenghost@hexbear.net 14 points 1 week ago

Well, he should consider himself lucky, since he's still in one of the early rooms. In fact, almost as good as the first one, since the amount of rooms with numbers smaller than 2×TREE(3) as a percentage of all the rooms, is zero. Almost every other guest has it worse.

[-] chemical_cutthroat@lemmy.world 4 points 1 week ago

That's my secret, I'm always moving.

[-] DarkCloud@lemmy.world 4 points 1 week ago

Just put a sign on the door telling everyone who comes there to go to the inverse wing. Or go set up in the inverse wing of the hotel yourself.

Everyone in the place is moving right along the infinite axis... But there's a whole empty wing of the hotel if you go left at the front desk.
