Is that just some random number, or is it something else?

Mine is 16,777,216 =D

Mine is 4,294,967,295.

My favorite number is e/4.

Chaitin's constant! Sadly, it's non-computable.

Are we allowed to choose from any ring?

My favorite number is e^(-pi/2)

"I love all my numbers equally!"

No, really, my fave depends on the moment, and what I've been doing lately. It can be 2, or 12, or e, or φ, or some other number entirely.

I'm extremely surprised you didn't say 17.

hey bmonk are you a hcssim alumni?

I attended the Ross program at the U of Chicago in the '70s.

I really like 2, because it's at the base of so many fundamental ideas (esp. symmetries). Though I think it's largely because most of our mathematical language is expressed with binary operators...

Well, someone is asking what your favorite number is. Here's a story about it if you haven't seen it. :-)

My fave is 4077 for non-mathematical reasons

my favorite is 69 for non-mathematical reasons

win

My fave is 4077 for non-mathematical reasons.

the one and only Favourite number is 1400/33 it's THE answer!

I thought "42" was "the answer".

just calculate all decimals of 1400/33 ...

I get it!

Gary look..

1400/33=42.424242424242....

The 42 is not only the whole number part, it is also the period that repeats!

i was comming up with 42 as well lol

my favorite number is 7. no questions asked

My favorite number is 73.

It is the 21st prime, and its mirror, 37, is the 12th prime, which also mirrors 21. In addition 7 * 3 = 21. Not to mention that 73 in binary is 1001001, which is a palindrome. Speaking of binary, of the 7 binary digits, 3 are ones.

I do believe that 73 is the Chuck Norris of all numbers

I think that "palindrome numbers" are actually called "capicua" at least in spanish. =3

Wow, I guess 73 really really really really really really really links with itself

I think that "palindrome numbers" are actually called "capicua" at least in spanish. =3

That's an awfully complex answer to a simple question, you know.

my favourite number is 2 as it is the oddest prime (that one is really old, wonder no one came up with that yet)

My favourite number is the smallest postive integer that has no interesting properties.

being the smallest positive integer with no interesting properties is an interesting property.

Contradiction!

Therefore, all integers are interesting.

Correction: the smallest positive integer is interesting. The relation wasn't applied to all integers.

Anyways, my favourite numbers are the powers of 2.

I'm pretty sure DarthPickley is correct.

Proposition 1: There exists a smallest positive integer n that has no interesting properties.

Proposition 2: n being the smallest positive integer that has no interesting properties is an interesting property of n.

But that's a contradiction. At least one of those propositions must be false.

So either a smallest positive integer that has no interesting properties does not exist. (Therefore all positive integers have interesting properties.)

Or being the smallest positive integer that has no interesting properties is not an interesting property. (That would be kinda lame.)

Pi rulez!!!!

People, enter here: http://favouritenumber.net/

Will be interesting =D

Mine's 28657, since it's the largest Fibonacci prime I can think of off the top of my head.

So,what's the largest perfect number you can think of?

My favorite number is 9pi/4.

Yahoo searches for "my favorite number is n" for n in {0,15} gives this plot. Of course, these are way too mainstream to consider. I prefer 4,294,967,295.

I am still a big fan of 2^(i*pi)

My favorite is either 6.02*10^22 or F.

my favorite number is pi x 599959958484892303823932829393u729292u289222

Why 'u'?
