Very Big Numbers

Postby Chfan » Tue Jan 19, 2010 11:00 pm UTC

I seem to have a fascination for massive numbers, for some reason. I looked up Graham's number on Wikipedia and was amazed at its magnitude. I know, it's nerdy. Does anyone else have a similar fixation? Any particular examples that you like about the size of certain numbers?
Just FYI, the guy isn't avatar isn't me. But he seems pretty cool.

The first *infinite* ordinal is pretty crazy, if you ask me.

0? Yes, it is quite large indeed. It's almost as big as any given epsilon.

What about 3000? That's a given epsilon, and it's not almost as big as that.

Speaking of ordinals, the first incomputable ordinal is way crazier.

9001. As it is over 9000, we know that it must an unimaginably huge number.

Also, the number now dubbed "xkcd's number". That number created in one of the comics by taking the Ackermann function with graham's number as arguments. (This too is over 9000)

DMM did an xkcd parody comic about this, in Irregular Webcomic. I have to say that goddamn but I love some of the annotations DMM writes.

Obligatory link to FG thread where we made gob-smackingly huge numbers: viewtopic.php?f=14&t=7469

Yes, big numbers are fun.

In other news, my Page-A-Day calendar once told me that the "centillion" (10^300) was the largest non-infinite number recognized by mathematicians. Wrong. Graham's number is far better. ^_^

Also, I'm pretty sure that mathematicians will recognize any number you can come up with. "Use" is a totally different matter, and then, yes, Graham's number is the largest number that was ever used for a proof.

Surely that ought to be 10^303?

Yeah, you're right. (In long scale, 10^600) http://en.wikipedia.org/wiki/Names_of_l ... numbers.22

EDIT: It's the largest number "with a conventional name." http://en.wikipedia.org/wiki/Centillion

Is it bad that I read this as a link to a finitely generated thread, before my brain kicked in?

Whoops, my bad.

That isn't what this planner said though, it said the largest number "recognized by mathematicians."
