    A Gardner's Dozen in TikZ

    1. Patterns

    By Peter Rowlett. Posted August 14, 2023

    Copy of Scientific American from November 1969 on top of a Scarthin Books bag and a copy of Sid Sackson's A Gamut of Games open to the instructions for Patterns II.

    Martin Gardner’s long-running column in Scientific American made it onto the front cover of the magazine twelve times. Gathering 4 Gardner refers to these cover stories as “A Gardner’s Dozen“, while pointing out that these aren’t his ‘greatest hits’ and the magazine artists didn’t necessarily reproduce the graphics as he would have liked them. Nevertheless,…

    A visit to The Mathematikum in Giessen

    Catenary curve made of foam blocks standing.

    My son and I visited The Mathematikum in Giessen. This is well worth a visit, we did it as a day trip by train from holiday in Frankfurt, which worked well because the museum is close to the railway station. The Mathematikum specialises in ‘hands on, minds on’ interactive activities, and we spent about 5…

    Bouton numbers: a new integer sequence

    By Peter Rowlett. Posted August 6, 2023

    In the 1901 paper that named the game Nim and provided its mathematical analysis, Charles Bouton defined “safe combinations”, positions that if you leave the game in this state, your opponent cannot win. In combinatorial game theory, these are \(\mathcal{P}\) positions (the previous player has already won), as opposed to \(\mathcal{N}\) positions (the next player…
