(the title says "circle number", but there is no appropriate english translation that i could find)

Haha, I found this too late but I love him.

Is anyone here doing anything special for Pi day this year?

Matt Parker recently posted a video on the distribution of dimples on golf balls: Golf balls: how many holes in one?

An image of an icosahedron formed by three mutually perpendicular golden ratio rectangles sits in front of That Feel Guy. The caption text says "They don't know that three mutually perpendicular golden ratio rectangles, with edges connecting their corners, form a regular icosahedron."

This is an excerpt from my math models textbook. It's about Lagrange Polynomials which is a technique that lets you fit a polynomial to a set of any number of unique points (x_1,y_1) ... (x_n,y_n) so long as all your x-values are different (otherwise it wouldn't be a function, and couldn't be a polynomial). The polynomial you'll calculate will be the unique, lowest degree polynomial that passes through all points.

E[S] = μE[N]

Every single odd number has an "e" in it.

Semi-related fun fact: The center of a KitKat is partly made of crushed off-cuts of the previous batch of KitKats. Which begs the question… what was the first KitKat made of?

saw this comment on veritasium's latest video titled the SAT question everyone got wrong.

The volume of a cylinder is found using the formula V = πr^2^h. Using π = 5, r = 10 and h = 10. Find the volume V.

It seems to have been real btw.

Behold: the cursed triangle.

was reading about cardoids when I was suggested mathematical deltoids.

I'm pretty sure you know what follows...
