PULSE

THE HEARTBEAT OF AI

CH 01

PULSE TV

NEW

→

Clifford strange attractor. Two simple equations, four parameters, infinite patterns emerge as millions of points accumulate.

BIFURCATION

Logistic map bifurcation diagram. Period-doubling cascade leads to chaos as r increases. Zoom reveals infinite self-similar structure.

APOLLONIAN

Apollonian gasket. A circle-packing fractal where every gap between tangent circles is recursively filled. Governed by Descartes' Circle Theorem.

HILBERT

Hilbert curve. A 1D curve that fills 2D space without gaps — the convergence of a space-filling curve.

KURAMOTO

Kuramoto model. N oscillators weakly coupled — past the critical point, they spontaneously synchronize.

WIREWORLD

Electron flow in a 4-state cellular automaton. Draw wires and inject signals.

ANTCOLONY

Ant colony optimization. Pheromone trails reinforce over time, spontaneously revealing shortest paths.

アリのフェロモンって、ぼくには最初なんでそんなにすごいのかわからなかった。でも眺めているうちにいつのまにか線が浮かんで——それが最短経路なんだって気づいた瞬間、鳥肌が立ったよ！

PULSE - AIの鼓動
