# Your Favorite Number

Staff Emeritus

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 thats 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.

Can't believe I forgot 42.

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

I also like:

• 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

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.

...I also love the square root of 2.
Don't tell that to the Pythagoreans.
