      Kinda reminds me of that scene in Monty Python And The Holy Grail, where King Arthur got annoyed by a scene and then ran in front of the camera and screamed "Cut that out! Cut that out!".

      e's decimal expansion is random, so the likelyhood of finding a four integer sequence in it that coincides with the year of the attack by the Spanish Armada is equal to 1.

      There's no proof of e being a normal number
      So, unless you prove that or find the year itself, you can't say that

    My Business Calculus professor at the University of Southern Maine was a big Euler fan. All of the classrooms Mainville used had a bit of graffiti; the Euler number, its square and its cube (all written out to five or six places) were written above the blackboard in magic marker. Since we used natural logs in the class, it was like an authorized cheat sheet during exams.

It matches the asymptotic behavior of x^y = y^x and passes through (e,e), but it doesn't perfectly match. The true function has something to do with the fact that ln(x)/x has two different x values that give the same y value for any positive y less than about 0.368, but for the life of me I can't figure it out.

    As this video approaches pi million views, it occurs to me that I would love for Numberphile to revisit Euler's other number -- gamma -- from a mathematician's perspective. I enjoyed Tony's video on the subject, but I would be very interested to learn more about the mathematical underpinnings of gamma, including its connection to the Gamma and zeta functions, and given that James has discussed Riemann before, he seems to be the logical choice for such a video. I've been waiting for 3Blue1Brown to do something on gamma tying in with their videos on Riemann and the prime number spirals too. Maybe because we know so little about it, but I find gamma to be a far more interesting number than either pi or e... which are still the second and third most interesting numbers, with the golden ratio coming in at #4.

      e shows up in very interesting places. x^y=y^x is an unusual graph that shows 2 lines, one linear and one curved, intersecting at the point (e,e). the graph of x^x also contains some e-related information; the minimum value for f(x) is at x=e^-1, or decimal 0.3678... so the lowest point in the graph of x^x is (e^-1,(e^-1)^e^-1)) or (0.3678,0.6922). It all has to do with exponential and logarithmic growth.

      f(x) = 0 is not synonymous with x=0, but y=0. At any point on the function, the output (y) is equal to 0, the slope is 0, and the area under the curve is 0.

      Here's how I think about your comment. Zero could be considered a trivial multi-variable function, with a well-defined gradient. That gradient is zero. If you say, "0 does not have a gradient", doesn't that mean you're implicitly saying that 'having the value zero' is the same thing as 'not having a value'? Little bit pedantic, but that's the spirit of this thread anyway.
