Your Favorite Number!

What is your favorite number?? And why??

Mines...umm...one of them...probably between 0 and several trillion...I can't decide.

But I'll just go with two. Why? Because that's the number of pop tarts in a pouch!

When people ask me to pick a number between 1 and 10 I always pick pi. Does that count?

Of course! But you better have cake in there somewhere...its my favorite.
 


\sqrt 7/9

why?

6(x) * 9(x) = 42
54x^2=42
x^2=42/54
x^2=7/9
x= \sqrt 7/9
 


Two. It's my number for relaxation. I read someone that said in order to relax pick a number and assign relaxation to it. Then whenever you're stressed think of the number.

Doesn't work. But 2 is still a cool number.
 


This is a tough one. Let's see, there's:
  • e, for obvious reasons
  • i, since \mathbb{C}^n is interesting
  • \pi, for its all-around significance
  • \varphi; I've always liked the Golden Ratio
  • \aleph_0
  • \frac{\pi^2}{6}, since it's a cool sum of \sum_{n=0}^{\infty} \frac{1}{n^2}
  • G, because of its gravity
  • k_e = \frac{1}{4\pi \epsilon_0} is rather electric
  • 2, the only even prime
  • the set of perfect numbers

Too many...can't decide.
 


Haha, i KNEW i'd get some great replies like these. :biggrin:
 


Can't believe I forgot 42.
 


27, only because of the odd amount of times it shows up in my life.

I also like:
  • Eddington's number, 15,747,724,136,275,002,577,605,653,961,181,555,468 ,044,717,914,527,116,709,366,231,425,076,185,631,0 31,296
  • Graham's number, g64
  • The xkcd number, A(g64,g64), where A is the Ackermann function

I feel kinda bad that I don't understand most of this lol.

That's what makes it so great :biggrin:

13 is my most favorite number. I've pretty much got that one to myself. In fact I have a bunch of favorite numbers, and 13 is the smallest one. So, in addition to being my most favorite number, it is also my least favorite number.

I like 4. Diagrammatically, it is very symmetrical. It is composed of 2 2's, which is a plus. It scales up easily with 8, 12, 16, 20, 24...

When I was learning how to count, and later to appreciate and manipulate numbers, 4 was my favorite. I don't know why.

6_{13} * 9_{13} = 42_{13}
but that is incorrect, hence \sqrt 7/9

I don't really have a favorite, but I've always liked 9 for much the same reasons you like 4.

I can't decide between mine but pi is very special to me, I also love the square root of 2.

Don't tell that to the Pythagoreans.

i have a weekness for 7

h

Everything interesting has an h in it.
 
  • #24


Also \hbar, \quad \epsilon_0, \quad \mu_0
 
  • #25


Gotta love googolplex.
 
  • #26


This thread has the potential for a lot of answers, so let's just say:
x:\forall x \in \mathbb{C}^n
(Hopefully some mathematician here can point out what the largest set is if I'm wrong.)

Ah yes and this reminds me of 6.02 x 10^23 <3 beautiful in more ways than one!

Infinity because it isn't one despite maths. :)

I like watching people trying to put the infinite and indefinite in a box, the mental masturbation alone makes infinity fascinating.

That and transcendentals like \pi\;\;\;\; e^x\;\; \sqrt {2}[/itex] etc which just never stop.
