Escher's most mind-bending piece

1mMar 27, 2026

An analysis of MC Escher's 1956 lithograph 'Print Gallery,' which depicts a paradoxical scene where a man views a picture that contains the very gallery he's standing in. Mathematicians in 2003 discovered the mathematical principles underlying this recursive artwork, including what should theoretically fill the mysterious blank space at the center.

The subset sum puzzle

0mMar 25, 2026

A mathematical puzzle game is presented where one player chooses 10 numbers from 1-100, and the other must find two distinct subsets with equal sums. The challenge is to determine which player has a winning strategy.

How (and why) to take a logarithm of an image

44mMar 22, 2026

The video explores how M.C. Escher's 1956 lithograph 'Print Gallery' can be mathematically analyzed through complex functions, specifically using logarithms to transform self-similar images into warped loops. The analysis reveals deep connections between Escher's intuitive artistic process and mathematical concepts like conformal mapping and elliptic functions.

Bacteria Grid Puzzle Solution

3mMar 21, 2026

A puzzle about bacteria replicating on a grid that asks for the minimum moves to clear 16 lattice points is revealed to be impossible. The solution uses a clever weighting system to prove mathematically that bacteria cannot escape certain grid boundaries.

The most beautiful formula not enough people understand

1h 0mFeb 27, 2026

A mathematician presents what he considers one of the most beautiful yet underappreciated formulas in mathematics - the formula for the volume of high-dimensional spheres. He derives this formula using an extension of Archimedes' method and explores the surprising behavior of spheres in higher dimensions.
