darts

Numberphile talks with Grant Sanderson of 3Blue1Brown about a darts puzzle with a shrinking bullseye. Solving it takes the volumes of high-dimensional spheres, and the answer turns up Euler's number.

Mark Rober shows an automatic bullseye dartboard that tracks a thrown dart with motion capture and moves in real time so it always hits the center. He spent over three years on the project.

Michael Reeves rigs up a camera and software that tracks a goldfish's movements to choose stock trades, tied to wallstreetbets sentiment. It is a comedic programming and electronics stunt.
