MATT PARKER: Stand-up Mathematician

[mikhail_simin]

An infinite number of mathematicians walk into a bar. First orders a beer, second orders half a beer, third orders a quarter. Bartender pours two beers and says, "y'all should really know your limit"

[Nulono]

Mad props to whoever built the table capable of holding two infinite stacks of bills.

[StuperUser]

"Infinity is not a process where you count and count and count and count and you eventually get there, it's a process of looking at all of it at the same time." is the best explanation of why infinity doesn't work like it feels like it should that I have heard in 38 years.

The hardest thing about having these two piles is actually laundering the money

[krakenwarrior]

I respect the editor for spending all that time rotoscoping those piles.

[Aoderic]

The whole time I was worried about Matt's safety, if he had knocked over one of the stacks, he would have been buried in an infinite pile of bank notes 😲😵💀

[isaac_aren]

What's funny about people quoting Vsauce to justify their wrong answer is that Vsauce also says the line "There are as many even numbers as natural numbers" and then immediately proves it

[garvellokenxvi]

An infinite number of days is as long as infinite number of hours.

But I would still pick the twenties, since they're are more convenient to use (which matters becouse I will be able to spend only a finite amount)

[JohnSmith-fgll]

The problem with the Hilbert Hotel is that to get a room at short notice you may have to bribe an infinite number of desk clerks - and you better have an infinite stack of $20s because there's no way these guys are gonna be happy with singles.

[evelynashe]

I'd still take the 20s, since they're easier to buy stuff with. Hopefully it includes an infinite bag of holding.

[MrKubaxius]

The biggest problem here is not that people don't remember details, it's that they will still confidently state something based on the thing they don't even remember.

[orphan-eater]

I feel bad for the guy in the infinite hotel that was in room when they had to move to double their room.

[erielvasan]

If a number said "I can't even" then it's definitely an odd number

[MayorofHopeville]

The comments have real "1 kg of steel IS heavier than 1 kg of feathers." type of energy.

[jacemandt]

When I teach about infinity, I like to point out that most mathematicians don't use "infinity" as a noun very often. They say that sets are infinite, or that a set contains infinitely many elements (adjective and adverb) instead. When they do say "infinity", it can usually be easily rephrased without the use of that word: "This quantity increases to infinity" means "This quantity increases without any upper bound."

[FabbrizioPlays]

Reminds me of the time I had like $82 in singles to use up, so I brought it when I was hanging out with friend. One of them asked why I had so many singles, and for some reason my brain saw fit to say "I was at the strip club last night, but I think I did it wrong."

[AdmiralJota]

There's a really weird visual glitch around 9:53 where the two infinite piles of money look like they're only finitely tall for some reason. I'm not sure what could have caused that.

[KoeiNL]

Hi Matt, I'm a bit confused. When you stand up and walk towards the door I can see the top of the infinite stacks of bills. Since you tower over them, does that mean that you are infinitely tall?

[awildted]

Just want to point out how great the cut vfx is for the "room switching" shot where two Matt's come out two rooms, one leaves and one enters the second room. Really seamless compositing! Impressive!

[ComfyCherry]

when people are taught infinity they really need to be taught that it is a concept not a value
