I wrote a thing with Sara Chari for the American Mathematical Society Feature Column! mathvoices.ams.org/featurecolumn/…

Wherein I attempt to justify visually (well via a series of visualizations) that we can possibly assign the value of -1/12 to the divergent series 1+2+3+… youtu.be/hB2F9lyr2_k #math #divergentseries

You might know a formula for the sequence of partial sums of squares... but do you know a formula for the sequence of partial sums of the sequence of partial sums of squares? Here's a visual proof due to C.G. Wastun: youtu.be/qLqtJVzkfu8

September almost over and I forgot to mention that the MAA Sept Math Horizons is available for your reading pleasure. The covers feature a fun puzzle hunt from Steven @Clontz.org@BlueSky and friends. Can you solve the conundrum at MaPP University? T&F STEM maa.tandfonline.com/journals/umho20

Here is a sudoku I made for the Fall MAA NJ-Section meeting last weekend, and now I want to share it here. The instructions explain everything needed but more details, a PDF, and the solution are on my blog here: quadratablog.blogspot.com/2024/11/maa-fa… #math #puzzle #sudoku #Maths #mtbos

November issue of MAA Math Horizons is now available online. Check out some fun articles featuring @leahwrenn David Nacin Jessica K. Sklar FUNDAPROMAT and more! maa.tandfonline.com/journals/umho20 T&F STEM

I’m excited to share that my latest book is officially out now! This unique book of mathematical puzzles also serves as an introduction to Group Theory. No prior background is needed, as all necessary mathematical concept are explained within the book. jdoqocy.com/click-10129441…

Current methods in the field are trained on atlases ranging from 1 to 100 million cells. In our newest preprint, we show that these same approaches tend to plateau in performance with pre-training datasets that are only a fraction of the size.
