mathlesstraveled.com is a personal blog at mathlesstraveled.com about math. Since 2009, 23 different Hacker News readers have linked it 30 times, most often “Factorization diagrams in Haskell”. No feed was found, so read it on the site itself.
Too few sampled comments (10) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for its explanations of factorization diagrams and related math visuals, such as the 17x17 monochromatic rectangles problem and the Collatz conjecture. Commenters cite posts as clear explanations.
Summarised by Claude from a sample of 10 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Math Less Traveled — off-beat mathematics: visual proofs, number theory, puzzles, fractals, topology and creative problem solving for curious minds.

HN discussionThis is brilliant! Now i want (to build) a drag and drop toy where i can multiply or summarize numbers that are represented in this way. To see how factors move (like boids). Is this visualization algorithm called something? The explanation link from a previous HN post seems to be broken: http://mathlesstraveled.com/2012/10/05/factorization-diagram...

HN discussionIt tells about the factorizations if anything, as that's the input dimensions they are using. If you haven't seen factorization diagrams, it's worth checking them out first: https://mathlesstraveled.com/factorization/ But visualisations can always deceive you into seeing something that's not there, e.g. correlation vs causation.

HN discussionThat was awesome thanks for sharing. For the first minute I wasn't expecting much, but the reflections part was so cool! Plus, this connects directly to the cyclic curves in the complex plane, e.g., https://mathlesstraveled.com/2015/06/04/random-cyclic-curves... The curves formed by the envelope of intersecting lines in the circular multiplication table are a slice of cyclic curve space. I animated this after readin…

HN discussionMy favorite way, though, is just to make a grid of pairs of integers (numerator, denominator), and then count them by spiraling outward on the grid. This yields duplicates, but that's ok. Calkin and Wilf cleverly avoid duplications by arranging reals not on a lattice but on a (Stern-Borcot) tree. http://en.wikipedia.org/wiki/Calkin%E2%80%93Wilf_tree http://www.mathlesstraveled.com/?p=94
