TL;DR

Hilbert curves and Fermat spirals have diverse applications in various fields, including snake game patterns, IP address assignments, light simulations, and sunflower growth patterns.

Transcript

Dear Fellow Scholars, this is Two Minute Papers with Károly Zsolnai-Fehér. What are Hilbert curves? Hilbert curves are repeating lines that are used to fill a square. Such curves, so far, have enjoyed applications like drawing zigzag patterns to prevent biting in our tail in a snake game. Or, jokes aside, it is also useful in, for instance, choosin... Read More
