can someone smart explain this to me
Please.
Tags: and thank you
An infinite number of
mathematicians walk
into a bar. The first one
orders a beer. The
second one, half a beer,
The third, a quarter of a
beer. The barman says
you' re all idiots" and
pours two beers.

suddenly, all of FJ commenters are mathematicians
We've all taken math classes before guys, no need to explain everything

This is described to be the sum of n = 0 to infinity, of (1/2)^n
Which in layman's terms, are:
1 + 1/2 + 1/4 + 1/8 + 1/16... (1/2)^n ...
If you try to sum this series, it'll become closer and closer to 2, but it won't even reach it.
You'll have to do this an infinite amount of times for it to ever reach 2.

This is called an infinite geometric series which can be calculated as (1/(1a)) where a <1 In this case a=(1/2). Thus (1/(1a))=2. a=1/2 because the series in expanded form looks something like this: (1/2)^0+(1/2)^2+(1/2)^3... and so on

The first beer is for the guy who ordered an entire beer.
The second is for the rest:
Half of it will go to #2
Half of the other half will go to #3
Half of the other half will go to #4
And so it will go forever.

And the bartender got not tip.
because mathematicians are assholes and they have their limits....
budum, tshhhh

The Limit as amount of beer ordered approaches zero of total number of mathematicians ordering is 2. The bartender gets their joke and pours 2 beers to accommodate them.

They are idiots because.....
1.) Building codes only allow a certain number of people in the building at a time (fire marshals and all that jazz).
2.) An infinite number of mathematicians couldn't fit in the bar.
3.) Bars don't sell '1/2 beers' or '1/4 beers'. You can either buy a beer or not buy a beer.

Each guy ordered half of what the last guy ordered. The bartender put 2 cups. One was for the first guy. The second one was for everyone else. The reason why is because they infinitely take half of the prior order, which will be less than 1; so the second one is just how much beer is ordered rounded up.

crusaderzav (05/18/2014) []
Nope, Because there's an infinite number of mathematicians. They each order half the amount of the previous order. so 1+1/2+1/4 would then equal w and 3/4 (what you said) But there's an infinite number of them. So you add 1/8+1/16+1/32 and so on. This total number will approach but never reach 2, practically. But it can be argued, and is generally accepted that if you did this an infinite number of times, you effectively reach 2.

Technically, it's one beer and one infinitely smaller beer.

The summation of the geometric function 1/(2^n) is taken from 0 to infinity. While the function never techniquely reaches two, it becomes infinitetly close to two and as a result equals it.

Personally I would have said, "You're all causing severe stress to our concepts of reality by existing," and left the bar to cry in a corner.
But that's just me.

This always gets me a little upset, an easy way to look at it is : You step half way across a room in one step, the next step you take half of the half you just stepped ( 1/2 > 3/4), this is called an asymptote. No matter what, if you keep halving yourself you are never going to reach zero ( the other side of the room). You can get infintesimally close but you will never reach the other side.
Basically, My inner bill is getting rustled.

Assuming that everything is additive, it would work like this:
1 + 1/2 + 1/4 + 1/8 + 1/16...
It works because there is infinite decimal place possibilities, which would inevitably add up to 2. Plus, there's gonna be a lot of ******* mathematicians in that bar.

My math class the advanced class btw was told to continuously cut a piece of paper in half, as were all the other classes.
They all stopped at an average of 1/64
We were getting up to and beyond 1/4096 and were needing to use magnifying glasses and tweezers. Yes we are insane.

Actually with calculus I believe you can prove that the bartender is providing them with exactly enough beer. But it's been a while..
