Mathematician Karl Weierstrass was born #OTD, Halloween, in 1815. 🧪 🎃 The fools at The Academy all said he was mad, but he showed them all in 1872 when he announced that he had created a MONSTER. Let's learn about the terrible thing he did. Image: Smithsonian Institution Libraries

Whenever a newbie is learning about arc length, I love to drop the monster on them, just to be a jerk.

The Weierstrass-monster: a function consisting only of edges, nowhere differentiable. I think it would be called a fractal today?

I love this function, when I first learned about it I was fascinated that it has a corner at every point.

Henri Poincaré was the first to understand the nature of Weierstrass's horrifying creation. He called it "an outrage against common sense.” Somehow, Weierstrass had stitched together a pathological function made out of pointed teeth and sharp corners, and brought the thing to life. (2/n)
