The Most Beautiful Equations

beautiful equationsThis is a nice comment-thread and poll on Quora responding to the question “What is the most beautiful equation?”

No surprise to see Euler’s Identity on top with a whopping 350 votes.

There are fun entries all throughout thread, and I definitely learned a few things through perusing.   And I guess I can forgive the participants for including some inequalities on the list.


  1. Tao Wang says:

    I would define beauty in mathematics and science as 1) short, 2) easy to understand, 3) describes an idea that is non-obvious. Euler’s identity certainly fits #1 and #3 but not #2. In my opinion, the most beautiful equation is F=ma.

  2. MrHonner says:

    Shouldn’t “Truth” also be a requirement?

  3. James T says:

    I would consider V-E+F=2

  4. Troy Singletary says:

    Personally I think the Dirac equation should be at/near the top. It predicted antimatter before it was experimentally discovered!

  5. da hua says:

    I think it’s e^ipi = -1 (Euler’s identity).

  6. Juejun Xiao says:

    I like the equation
    1+3 = B

  7. Juejun Xiao says:

    whats the Limit, as i approaching to u, of the function (i + me),
    The limit is u and me.
    Don’t throw rocks at me.

  8. hands down. (∆x)(m)(∆v)=h/2
