Digitwalker

numbers go for a walk

Bet on your number: add a few and see whose walk travels farthest.

🏆 Numarathon Hall of Fame

Same race for everyone: 1000 digits, turn 90° anticlockwise, integer part included. Farthest from the start wins. Only irrational numbers can enter. Build yours from π, e, φ, √2 and friends (try pi + sqrt(2)). The first person to enter a number gets the credit.

#NumberIntroduced byDistance

Every digit is a step length: walk that far, turn, repeat. Lines start dark and get lighter towards the end of the number. Distances are in units (u), where 1 u is the step for the digit 1.

Two kinds of walkers

Rational numbers have found their purpose. Their digits fall into a rhythm and repeat the work they love, again and again, content inside their loop.

Irrational numbers never settle. Their digits never repeat, so the path never quite comes home. It keeps wandering into new ground, as if looking for something.

Whether the digits of π, e or √2 are truly “random” is still an open question in mathematics. The walk just lets you look.

Where this comes from: my article Visualizing the Irrationals: From Math to Art on Medium.
