Peter Rowlett @peterrowlett.net · 24/08/2026Went to the Boole memorial in Lincoln. Boole is teaching two children some logic. One has a slate labelled “ALICIA”, his daughter’s name. Any ideas why the other is labelled “TAD”? (It amused me that while Tad is copying from the board, Alicia, who became a 4D geometer, is drawing some geometry.) 2154
Peter Rowlett @peterrowlett.net · 05/08/2026The new issue of The Mathematical Gazette has arrived! My second as editor. 😁 My editorial discusses what the journal is about and who reads it.

Peter Rowlett @peterrowlett.net · 23/07/2026I continue to wonder about utility of #genAI. I gave Claude some text I wrote and asked it to find and add suitable references. In the response it gave some warnings that straight-up assumed I am a student cheating on an assignment. 🤯 130
Peter Rowlett @peterrowlett.net · 22/07/2026Not exactly showing the power of the Approximation Day Bot, but it’s a biggy. Question is: what happens on the other days of the year? The answer is silliness - give it a follow and find out! 251
Peter Rowlett @peterrowlett.net · 19/07/2026My son got a calculator for secondary school in the autumn, so we took it for a test. He drew a series of triangles and measured the sides, then worked out their ratios and plotted them. Then we tried some other buttons on the calculator and discovered sin, cos and tan make the same values! #tmwyk 0161
Peter Rowlett @peterrowlett.net · 17/07/2026Heading home from my last school visit of the year.
