Featured Contest: Equations as Art 2017

  1. Sep 20, 2017 #1
    The goal is to create the most beautiful or interesting equation aesthetically (pleasing to the eye).
    This is not about it's mathematical significance. Get your inner designer on!

    • Each member is allowed to post one equation
    • The equation can be completely made up
    • Must use LaTeX
    • Be creative!

    To vote for an equation simply click the "like" button. You can vote more than once. The contest will close next Wed Sep 27th.

    The winner will receive a PF T-Shirt!

    ps. do not try to register new usernames for more entries or for likes. It's painfully easy to figure these out.

    Have fun! Go!

    I find it difficult to disregard meaning when it comes to aesthetically judge an equation so I will go with Stokes’ theorem for integration of differential forms. Both for its aesthetics in terms of its integral signs, simplicity in the form of the ##\omega##s appearing on both sides, and meaning:
    $$
    \int_{M} d\omega = \oint_{\partial M} \omega
    $$

    With the Fibonacci sequence ##F_n##, the Lucas sequence ##L_n## and the Catalan sequence ##C_n##
    $$
    \sum_{n\in\mathbb{N}}\frac{1}{n}\cdot\frac{1}{n}\cdot \frac{1}{n+1} \cdot \frac{F_n \cdot L_n}{C_n} = \frac{(2\pi)^2}{\sqrt{5}^5}
    $$

    This is a fun thread! I agree with @Orodruin that much of the beauty comes from the meaning; so I will go with an extension of the Cauchy integral formula.
    $$\oint\frac{f(z)\;dz}{\left(z-z_{0}\right)^{n+1}}=\frac{2\pi i}{n!}f^{(n)}(z_{0})$$

    Here's one I like:

    $$\int~e^x = f(u^n)$$

    You might need to think about this one a bit ...

    I think I saw this on a T-shirt once. :biggrin:

    This is one of the few cases where the equality no longer holds if you actually perform the integral ...

    Finally an equation that makes sense. Looks like I have a future in mathematics after all.

    Only if you are very young and think that girls have cooties, or very old and can remember the how but not the why.

    ##3987^{12} + 4365^{12} = 4472^{12}##

    For some strange reason I don't buy it ...

    Which you are of course in your full right to do. Just saying I agree it is a valid contest entry, but not a valid actual equation. :smile:

    This one is the beauty in the contest and will always win, if mathematicians are honest with their votes, I think. I like the positive form ##e^{i\pi}+1=0## a little more, as there is also the ##0## involved: top of the pop, so to say. And I really have to fight myself, because I still have two other beauties in mind ... d... rule ##1## ...

    This was my mantra for a while.

    e + 1 = 0

    I'm willing to be the idiot and admit I don't get it.
