Best two weeks outdoors

Outward Bound, Oregon

15 days with Northwest Outward Bound School: a week of rock climbing at Smith Rock, then alpine backpacking around Broken Top and a roped climb to its summit.

Sketchbook

Design is one of my hobbies, and math makes good pens. Each of these is drawn live in your browser, from equations, rules or algorithms; click one, or its button, for a new version.

Curves and chaos

Lorenz attractor: chaos from three equations
Golden angle: 137.5°, like a sunflower
Lissajous: two sine waves
Spirograph: a wheel in a wheel
Julia set: z² + c, as contours
Flow field: ink on noise

Computation and discrete math

state: right··1011···1011 + 1 = …step 0 of 8
Turing machine: adding 1 in binary
Game of Life: four rules, endless patterns
Pascal’s triangle mod p: fractals in counting
Collatz: every path ends at 1 (so far)
Binary search tree, built one insert at a time
Königsberg: 7 bridges, all odd, no Euler walk
