Blog by a City University of New York (CUNY) professor who researches mathematical and philosophical logic, particularly set theory, with a focus on the mathematics and philosophy of the infinite. Posts, which date back to 2011, have included "The mateinn problem of infinite chess is decidable"; "A question for the mathematics oracle"; "Math for sixyearolds"; "Satisfaction is not absolute"; "Math for sevenyearolds: graph coloring, chromatic numbers, and Eulerian paths and circuits"; "Win at Nim! The secret mathematical strategy for kids (with challenge problems in transfinite Nim for the rest of us)"; "Upward closure and amalgamation in the generic multiverse of a countable model of set theory"; "Famous quotations in their original firstorder language"; "All triangles are isosceles"; "The finite axiom of symmetry"; and "What is the theory ZFC without power set?" and "On number sense—Would one day of NYC coffee fill the Statue of Liberty? And other fun questions…" and "Buckets of fish!"
