Some of you probably already know this, but "Gibbs phenomenon" refers to the fact that fourier series approximations will always "overshoot" jumps (like those in a square wave) by a certain amount, no matter how many terms are used in the approximation.
From wikipedia, the overshoot converges (as you add more terms) to 8.9% above/below the jump.
I'm just mentioning this to complain about it. If it's possible for math to be "ugly", IMO this is it.

wolframalpha.com/input/… why this doesn't work :(

@PhiNotPi I have to disagree: The notion of convergence is dependent on a measure of distance, and the whole Fourier theory is mainly built on an L2 space. So I'd argue that you consider the "wrong" notion of distance :)

@El'endiaStarman yes it does, and I just found out they are ~2 hours away from my location. Maybe I'll move there and work for them

@NathanMerrill I am now imagining your 2-week notice to Microsoft...

@Feeds His physical demonstrations are brilliant, as always. Seeing the cascading failure in his model example made it click for me how rolling blackouts can/do happen.

@El'endiaStarman Maybe :) Unfortunately, they don't have any software development positions open.

@DJMcMayhem Coleoids (squids et al.) are literally "ink-fish" in german.
