Well... The one constant through all the years, Cruel, has been ~~baseball~~ Claude's birthday. :)

I think he has more birthdays than anyone else.

Happy Birthday, Claude! Hope you have a grand time!

Knuth's up-arrow notation can just about handle Wu's age. =P

I never got far enough in math to learn this stuff on my own. I was briefly introduced to that once by a math grass student in a physics class. My question that he couldn't answer, and that I can't answer myself after checking the wikipedia page, is why not just use exponents?

I'm not sure myself. I think it might have a lot to do with computing, since Donald Knuth is a computer scientist and specialized in computational algorithms. Or it might simply be more intuitive to read or type with a keyboard.

Once you understand the system, 3(Arrow)(Arrow)4 is a lot easier to grasp than 3^7625597484987.

Yeah, but surely it's identical to just saying 3^3^3^3.

That said, I just read the article again for about 15 minutes. The utility appears to be when that second number increases. For example, 3 arrow arrow arrow arrow arrow 76.

I don't like mathematics with no applicability to physics, and with the number of atoms being approximately 10^80, I saw no utility in the notation.

Do computers use numbers this large very often?

Computers can only handle mathematical operations up to a point (and even before that point, there are big limitations in how large one operator is compared to the other).

I mean, you can certainly visualize larger numbers at will, but the computer won't do anything with it.

There's nothing in particular preventing you from representing huge numbers on a computer. Such representations couldn't be used "natively" in the execution units, but it's not like the human brain has streamlined up-arrow registers and execution pipelines either.

Speed is a potential issue if you're going reeeaaaaallllyyyy big and need an exact answer, but with billions of 64-bit ops per second available, you can get a decent amount of work done in reasonable time.

I'm not quite sure what you're referring to here.

And that is the long answer. :p

Was talking about how you can't sum 2e63 with 2e-63 and have the answer in a single byte without losing precision, even when the system is capable of storing up to 2e63 and down to 2e-63.

Certain numbers, like Graham's number, are too big to even be represented with exponents.

Pretty soon you'll have the age pre-requisite met to take his job!

Happy Birthday Mr. Claude.

Well, except for people who make age jokes.

Oh, wait, that was ALL OF YOU

I heard your birthday message in the tower about a week ago. I'm just wondering when I'm gonna hear mine.

Happy B-day Claude. Thanks for setting all this up over the years.

Since Mig posted the thing already, I figured I'm now safe to post our contribution separately.

Happy Birthday, Claude!

Wow, thanks to Nico, my 91 year old father got to say happy birthday too!

(For all you youngsters out there, he's the voice of the surly dwarf, and we just watched the Seahawks beat the 49's yesterday!)

Another birthday song.

Didn't think it was possible.Do numbers really go that high?

Only until Bungie nerfs Claude's age.

They'd have to bring Zero up to 35 to even it out.

Theoretically, yes.
