The Circumference of an Ellipse
1+ mon, 1+ day ago (36+ words) If you remember basic school geometry, you probably know that the circumference of a circle is given by C = 2πr. The area of an ellipse is also easy to calculate: A = …...
Reproducing a geometry theorem diagram
2+ mon, 6+ day ago (251+ words) I ran across a geometry theorem with the following diagram. The theorem corresponding to the diagram is interesting, but I found reproducing the diagram more interesting. The segment AB is a diameter and the line CD is perpendicular to the…...
Circle Generator Minecraft: Build With a Circle Chart
2+ mon, 6+ day ago (1011+ words) Building a circle in Minecraft without help is a geometry problem most players don’t want to solve. The block grid doesn’t cooperate with curves. Every diameter requires a different block pattern. A minecraft circle graph displays a pixel-art approximation of…...
Approximating even functions by powers of cosine
4+ mon, 1+ week ago (221+ words) A couple days ago I wrote a post about turning a trick into a technique, finding another use for a clever way to construct simple, accurate approximations. I used as my example approximating the Bessel function J(x) with (1 + cos(x))/2. I…...

Billiard Fractals: The Infinite Patterns Hidden in a Rectangle
9+ mon, 2+ week ago (1718+ words) Complex systems often appear chaotic or incomprehensible, yet closer examination reveals that such complexity can frequently be reduced to a simple underlying mechanism. By systematically removing layers of emergent behavior, one can uncover a fundamental rule or equation from which…...
