I have posted the 238th Carnival of Mathematics!

https://www.fractalkitty.com/238th-carnival-of-mathematic/

If I missed something please let me know.

There is an extremely slow bit of javascript for untouchable numbers that hopefully won't make the post untouchable.

Thank you @aperiodical for organizing this.

This month we have posts from @mjd Peter Cameron, @two_star, @j2kun, Brian Clegg, @fortnow @KarenCampe, Amédée d'Aboville, Ed Vogel, @standupmaths

There was also an amazing amount of math and art being shared on blueSky with @Ayliean 's math art March prompts

last night I went on a wiki walk starting with Donald Knuth's impressive body of work and the title of his novelette "Surreal Numbers" piqued my interest

this led me down a delightfully confusing but fascinating peek into the weird side of math ft. The Monster, Baby Monster, magic squares and phrases that cracked me up like "weakly inaccessible cardinal"

def gave me a new perspective on cardinality which I mostly deal with in the practical sense with system telemetry

These two art pieces are based on the deformation of a hexagonal tiling into a topologically equivalent "tiling" composed of parts of concentric circles, all parts having the same area (third image). Selecting one hexagon as the center, we transform it into a circle of radius 1. Next concentric circle will hold the 6 adjacent tiles as sectors of rings. And so on, the circle of level n will have radius sqrt(1+3·n·(n+1)) (difference of radius when n tends to infinity approaches sqrt(3)). This map can be coloured with three colours, like the hexagonal tiling. For the artwork, suppose each sector of ring is in fact a sector of a circle hidden by inner pieces. Then choose a colour and delete all pieces not of this colour. Two distinct set of sectors can be produced, one choosing the central colour, one choosing another colour. Finally recolour the pieces according to its size.

**The Secret Formula: How a Mathematical Duel Inflamed Renaissance Italy and Uncovered the Cubic Equation**

Daniel J. Curtin

“_Fabio Toscano, a science writer, lucidly presents not only the solutions of the cubic equation but also the history of the problem and the development of algebra in general from Diophantus, through the Islamic scholars, to Renaissance Italy._”

**Generative AI and accuracy in the history of mathematics**

“_This process is illustrated by querying ChatGPT with questions from a history of mathematics quiz designed to highlight the common occurrence of mathematical results being misattributed. ChatGPT's performance on a set of decades-old common misconceptions is mixed, illustrating the potential for these systems to reproduce and reinforce historical inaccuracies and misconceptions._”

"My methods are really methods of working and thinking; this is why they have crept in everywhere anonymously."

Happy Birthday Emmy Noether!!

She made many important contributions to abstract algebra. She proved Noether's 1st and 2nd theorems, which are fundamental in mathematical physics. She developed theories of rings, fields, & algebras. In physics, Noether's theorem explains the connection between symmetry & conservation laws.

**Born On This Day**

Mathematician, astronomer, and physicist Pierre-Simon Laplace was born in Beaumont-en-Auge, Normandy, France on this day in 1749.

“_He proved the stability of the solar system. In analysis Laplace introduced the potential function and Laplace coefficients. He also put the theory of mathematical probability on a sound footing.”
