Just thought I'd share this. Don't know if anyone has seen it, but I found it rather amusing.

^{Disclaimer: I know why it doesn't work and am not trying to push this as some "new" maths.}

Oh dear god. Don't get me started again...

And could someone please tell me whether I was wrong or right?!

I'm very insecure.

NOT!

I just can't remember what that was called. Something accelerating towards infinity, infinitely faster than infinity. (hic!)

Sorry...

:)

 

[JaredJames]

Ah, nevermind then.

Pity, didn't think it would be in the maths section, given what it is.

I always respond to it with "Archimedes here. Yes, I do have a problem with it, *explanation about circumscribing and inscribing* you should view my work."

 

[Mathnomalous]

1/3 = .3333333333...

(3) 1/3 = (3) .3333333333...

3/3 = .9999999999...

1 = .9999999999...



I have earned a place in the Math Hall of Fame! Btw, I, too, would have a problem if my name was Archimedes; what kind of parent names his kid Archimedes!?

[The legend]

(3) 1/3 = (3) .3333333333...

3/3 = .9999999999...

1 = .9999999999...

The same thing can be done by greatest integer function too...




WHAT!
THIS ISN'T THE MATH SECTION??

At least they did not name him Pi.

 

[Jimmy Snyder]

I suspect that by using appropriate geometrical shapes and a similar limiting argument, you could prove the circumference to be any real number greater than or equal to pi and even prove that the circumference is infinite.

This reminds me of the following logic:

"So,
If she weighs the same as a duck,
then she's made of wood,
and therefore,
A WITCH!"

(Also reminds me of most political logic)

Hey, now! That's the number that I put on my baseball jersey.

 

[jobyts]

What I don't understand is how does it prove Pi = 4!. I didn't get the factorial part.

 

[leroyjenkens]

I always round Pi down to 3.

 

[G037H3]

it's part of the trolling

it's saying that pi = 4, not pi = 4!

 

[Mathnomalous]

That is one loooooooooooooooooooooooooooooooooooooooooooong baseball jersey...

What can I say? I used to be fat.

 

[Mathnomalous]

What can I say? I used to be fat.

Infinitesimally fat?

 

[G037H3]

Infinitesimally fat?

His blubber was a fractal. :X

I'll have you know, you young whippersnappers, that I ballooned up to 132 lbs. when I was playing ball. That extra 5 lbs. above my off-season weight was pure muscle.

man I hope you just got trolled...

Archimedes will be really be pissed off when he see his name appear with that face in the last picture.

I see a resemblance.

 

[JaredJames]

It's the spitting image of him.

Have you read 'The life of Pi' ? Brilliant book!

Sorry I don't get it? What is the problem? Why are you surprised at this result? Am I missing some sarcasm?

I'm in the dark too...

 

[FlexGunship]

Is there such a number as 0.99999...98?

Where the "9" portion repeats forever but the last digit is an "8"??

 

[JaredJames]

Where the "9" portion repeats forever but the last digit is an "8"??

Doesn't that contradict itself?

 

[FlexGunship]

Doesn't that contradict itself?

...no...

 

[disregardthat]

Surely there are many such numbers!

Take for example 0.8 = 0.79999...
