The Carnival of Mathematics, a monthly gathering of mathematical blog posts, continues to connect the global math community. For over a decade, this event has been hosted by various math bloggers, showcasing a wide range of mathematical topics, from recreational puzzles to advanced research. It serves as a valuable resource for mathematicians and enthusiasts alike, offering a way to stay informed about current trends and innovative ideas within the field.

The latest edition, Carnival of Maths 239, is now available at Reflections and Tangents, featuring blog posts from April 2025. This edition, like its predecessors, aims to broaden the accessibility of diverse mathematical discussions to a larger audience. Readers can expect to find explorations of topics like origami mathematics, as well as discussions of mathematical concepts relevant to daily life.

Besides the Carnival of Mathematics, other events are taking place within the math community. An Origami Challenge was undertaken in schools by ETH students, who visited schools and taught about origami and its relationship to the mathematical world, and a simple way to generate random points on a sphere was recently highlighted. These varied activities showcase the dynamic and engaging nature of mathematics and its diverse applications.

The online mathematics community is buzzing with activity, as evidenced by the 238th Carnival of Mathematics, hosted by Aperiodical. This month's carnival showcases diverse submissions and beautiful math art, starting with an exploration of the number 238 itself. Found to be 2 x 7 x 17 and the sum of the first 13 primes, the number also inspired community contributions, with users pointing out its appearance in uranium isotopes, hexagonal representations, and even birth minute celebrations. The carnival highlights the engaging and creative ways people interact with mathematical concepts online.

The carnival features a collection of blog posts and activities from various math enthusiasts. Number yoga is explored as a technique to develop creative reasoning and comprehension in mathematics. This involves noticing details, wondering about possibilities, and creating explanations or related puzzles. Also featured are posts on polyominoes, a modern presentation of Peano Axioms, practical math for programmers, the Monty Hall Problem, and group theory using Zoombinis. Karen Campe also continues her visual "Go For Geometry" series.

Furthermore, the online discussion includes extensions of basic geometry, focusing on pedal triangles and related theorems. A blog post delves into generalizations of perpendiculars from a point in a triangle, highlighting properties of the orthocenter and the orthic triangle. The orthic triangle's perimeter and its connection to the angles of the original triangle are discussed. The community also shares the art from Ayliean's MathArtMarch.
