I'm a bit disappointed that Michael describes al-Nayrizi's and Perigal's (families of) simple perfect squarings of the (flat square) torus as different. They are, in fact, identical—not just “congruent” or “equivalent” or “isomorphic”, but actually indistinguishable. They only look different... Continue reading

Today I'm finally releasing a final (or more honestly, “final”) pre-publication draft of my Algorithms textbook under a CC-BY license. This 448-page textbook evolved out of a subset of the algorithms lecture notes I've been maintaining for about 20 years.... Continue reading
