    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 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?

    [tex] \sqrt 7/9 [/tex]

    why?

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

    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 [tex]\mathbb{C}^n[/tex] is interesting
    • [tex]\pi[/tex], for its all-around significance
    • [tex]\varphi[/tex]; I've always liked the Golden Ratio
    • [tex]\aleph_0[/tex]
    • [tex]\frac{\pi^2}{6}[/tex], since it's a cool sum of [tex]\sum_{n=0}^{\infty} \frac{1}{n^2}[/tex]
    • G, because of its gravity
    • [tex]k_e = \frac{1}{4\pi \epsilon_0}[/tex] is rather electric
    • 2, the only even prime
    • the set of perfect numbers

    Too many...can't decide.

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

    I feel kinda bad that I don't understand most of this lol.
     
  14. Re: Your Favorite Number!!

    That's what makes it so great :biggrin:
     
  15. Re: Your Favorite Number!!

    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.
     
  17. Re: Your Favorite Number!!

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

    I don't really have a favorite, but I've always liked 9 for much the same reasons you like 4.
     
  19. Re: Your Favorite Number!!

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