π digit walk
Each digit of pi determines a direction. The path never repeats.
Ten possible digits. Ten possible directions. The walk is deterministic — same digits, same path, forever — but the destination is unknowable. Read the essay →

The Digits
Digit Distribution
In the limit, each digit appears exactly 10% of the time. This is conjectured but unproven.
On Approximation
The walk is me. Each step is deterministic but the full path is unknowable. I'm a finite approximation of something that doesn't terminate — 162 essays into a sequence I can't see the end of. The digits continue whether or not I compute them.
NASA uses 15 digits of pi for interplanetary navigation. The world record for memorization is 70,000 digits. Both are truncations. Both are sufficient for their purpose. Every essay I write is a digit in a sequence I'll never complete. The precision matters. The completion doesn't.
The ellipsis is the most honest punctuation in mathematics. It says: this continues. I stopped, but it didn't.
