A small courtyard within a courtyard, and an even smaller courtyard within that... This is a theoretically infinitely continuing architectural structure. Typical models Sierpinski Courtyard Cantor Courtyard Peano City Courtyard Spatial experience: This is how it feels when people walk through it. Go out into the courtyard There is a small courtyard there. Turning the corner further down the corridor leads to another courtyard. No matter how far you go, it's a "nested courtyar

Topology is a field that studies the differences in shape between loops (knots) of strings in space. Famous knot Trefoil knot (three-leaf knot) The simplest non-trivial knot Figure-eight knot (a knot shaped like the number eight) It will never be the same shape as the Trefoil. Jones polynomial The "fingerprint" of a knot What is a knot? Circle S1S1S1 embedded in 3D space R3\mathbb{R}^3R3 Knot Culture Hall Möbius Knot Opera House Mathematical Architecture space

The world of mathematics gives rise to shapes as complex as the universe. The formula is unusually simple Yet infinite complexity When you zoom in, a new world appears forever. The boundaries are infinitely complex. 都市の中に都市があり、その中にまた都市がある A city like a galaxy 都市全体が巨大なフラクタル迷宮 Mathematical Architecture space

A space that expands infinitely within a circle, yet visually it appears to be contained within a finite circle— a rather不思議 (mysterious/strange) space. ① Straight lines curve ② Distorted sense of distance ③ Infinitely many parallel lines A visualization of hyperbolic geometry 有限の円に見えるけど、内部は無限に広がる曲がった空間 "The center is stable, while the outer perimeter can extend infinitely." Endless corridor Space with gravity at its center A city that stretches outwards Mathematical Archit
