This framing is nuts.

Cover art for Discover Calculus. The background shows a plane flying over water in an arc. Reflected in the water is the plane and its arc but also diverging curves, rippling in the water. In the background is a bridge and some lights. The sky is dark with shining stars, a crescent moon, and beautiful clouds. The whole picture is a warm grey/brown with black hatch shading and white highlights. Discover Calculus Single-Variable Calculus Topics with Motivating Activities Peter Keep
It's here! @acidlich.bsky.social created this beautiful cover art, perfect as a representation of the book. While students will mostly be interacting with the book digitally, I'm very excited for the printed copies that we'll be making to give to students as well!

REED COLLEGE M A T H E M A TICS & ST A TISTICS COL LO Q UIU M Braids and Combinatorics THURSDAY, MARCH 12TH, 2026 SNACKS AT 3:15PM - TALK BEGINS AT 3:40PM ELIOT 314 CRAIG WESTERLAND University of Minnesota Combinatorics is, in principle, the subject devoted to counting certain kinds of mathematical objects. Several objects appear regularly in this story: subsets, partitions, permutations, and the like. Iโll begin with an introduction to these objects and how combinatorialists count them. With that in hand, Iโll discuss โbraidedโ analogues of these constructions โ these have a much more geometric flavor, but still retain some of the original combinatorial aspects. This allows us to upgrade the familiar notions of finite sets and functions between them to a world of braided sets and functions.
This week's math colloquium talk at Reed features my academic sibling, Craig Westerland, speaking about Braids and Combinatorics! ๐งฎ

My linocut shows a young Olga Ladyzhenskaya in profile, from the shoulders up in a gradient of navy blue at the bottom to pale burgundy at the top on cream coloured washi paper. Sheโs wearing a shirt and jacket with her hair up. Sheโs facing some text, carved in reverse, with some words in Russian and mathematics. The text explains this is the system of Navier-Stokes equation, initial and boundary conditions. Below her is a diagram of laminar flow eddying into turbulence. The text reads "ัะธััะตะผั ััะฐะฒะฝะตะฝะธะน ะะฐะฒัะต โ ะกัะพะบัะฐ" which means 'a system of Navier-Stokes equations' and also "ะดะปั ััะฝะบัะธะน" which means 'for functions' and "ะฟัะธ ะณัะฐะฝะธัะฝัั ะธ ะฝะฐัะฐะปัะฝัั ััะปะพะฒะธัั " which means 'under boundary and initial conditions'.

Today, we send our congratulations to PMP mentee Travis Cunningham, who recently made available through arXiv his first solo paper. Travis is gearing up to apply to graduate school and has several papers coming up soon. Stay tuned!

Over on Mathstodon, I follow an account that posts snippets from LOTR on the corresponding day. Today's was Theoden answering Saruman.
I guess Tolkien knew a thing or two about war ...

Math history question: Is ฮณ:[0,1]โX the notation for a path in a space X because
(1) ฮณ is the third Greek letter โ Roman c which stands for curve;
(2) orthographically, ฮณ โ especially when handwritten โ looks like a curve; or
(3) Cauchy chose it at random for a complex path integral and it stuck?

It's finally here! "Linear Optimization: A Geometric Inquiry Course" gives an inquiry based course in linear optimization supplemented by technology for intuition building. A great class for interests in either pure or applied math! Physical Copies now on sale: www.619wreath.com/store/p53/Li...
Thank you John!
If I have another child, I will name them โThe Natural Number Zeroโ.
This is a (vacuously) true statement.
Imagine being named after the subject you teach.

โฆstruggling with content, then letโs address this instead of kicking the can down the road.
I started doing something similar for homework extensions. First time no questions. Second time, we need to meet to chat about why itโs happening, and to see if there is some issue that needs to be addressed. Sometimes itโs a one off thing thatโs not likely to reoccur, but if theyโre..:
