For the second time this year, I’m a victim of budget cuts and my coaching position is being eliminated 😭. Please let me know if you know of anything math ed related (or something education adjacent)! Thanks!

A great blue heron in the afternoon sunlight while perched on the side of a metal structure beside a tree. The blue sky can be seen behind the heron, as well as the greenery of the tree. The bird’s grey colours are visible, along with the black patches above its head. Its beak, showing yellow, dusty brown, and dark green tones, is also visible. The head possesses a white patch around the base of the beak and the top of its head. Brown feathers can be seen on the wings, as well as dark lines across them. A great blue heron in the afternoon sunlight while perched on the side of a metal structure beside a tree. The bird shows the left side of its head as the warm sunlight bathes its body. The feathers that form a tuft pointing backwards are clearly seen as the bird shows a very serious expression as it looks towards the right.

Some pics at the Gulf Coast marshes the last few days! In this case again, a great blue heron ( a close relative in bioogical terms of the great egrets ). This one was also just showing off their beauty <3!

A watercolor painting. the corner of a small house on the right and a plank fence running from left to right with a tall cottonwood  framed by a twilight sky on the other side of the fence. You can just see the peak of the roof of the house next door and a tall spruce standing in the background on the left. The sky is dark blue except for a small line of clouds at the horizon lit by the sun setting on the opposite horizon. The moon hangs in the branches of the tree  just above the roof of the neighbor's house.

Our backyard in Vegas.

I had a similar conversation with two HS kids about their math research papers for a Chicago STEM Fair.

"Write up all the great work you did and include a "follow up research" section."

Fresh perspectives are as important as proof perfection.

imho

Ask permission and have them joke about saying "no." Not all of them do that but more than enough.

Title slide: From Intersecting Curves to Celestial Arcs: The Contributions of Islam to Mathematics. By Sara Rezvi, Ph. D. Dominican University Assistant Professor, School of Education, Chicago, IL

Tonight I heard the amazing Dr. Sara Rezvi speak at Math for America. Loved hearing her talk about the contributions of Islamic mathematicians, with examples from al-Khwarizmi to Miryim Mirzhakani. We used Desmos to look at Omar Khayyam’s solutions to cubic equations. 😃 #MTBoS #IteachMath #MfAProud

Radcliffe graduation photo of Ellen Dorrit Hoffleit, who is seated and wearing a cap and gown.

Astronomer Ellen Dorrit Hoffleit was born #OTD in 1907. She discovered more than 1,000 new variable stars over the course of her career, worked in the Harvard and Yale observatories, and edited the Bright Star Catalog. 🧪 🔭 👩‍🔬

Interior photo of just inside the front door.  Features a cabinet about 4 feet tall by 3 feet wide with a clown's face and balloons painted on it.

Once upon a time you get a "Clown Shoe Cabinet" at Walmart, I guess that tracks.

Walmart no longer carries "Clown Shoe Cabinet." Can we suggest...

Last week this game gave away the optimal value for all puzzles, and everyone I spoke with said that it killed all the suspense.

That means what's interesting is not just finding a good solution, but also convincing yourself of its quality

It is not a very tiresome proof by exhaustion but I keep hoping for some insightful "aha" like checkering a 5x4 to show the tetrominoes can't tile it.

Graphic layout featuring a dark blue header with the “HMS – Her Maths Story” logo at the top. Centered below is a black panel displaying a gold tree made of numbers, mathematical symbols (including π), and teal flowers, with the word “Mathemagica” in gold beneath it. The lower section has a light textured background with the title “The Magic in the Numbers: The Story of Mathemagica” and the byline “By Shreya Roychoudhury.”

Check out our latest blog post by Shreya Roychoudhury, the founder of Mathemagica (Instagram: @math.emagica): “I am an engineer, a founder, and a woman who refuses to be subtracted from the equation.”

A basin exit plot, showing chaotic structure Title/author list/abstract of the paper. The abstract reads:

The photon ring of a Kerr black hole decomposes into a self-similar hierarchy of subrings. Here, we show that this self-similar structure persists in phase space. Moreover, near the photon shell of bound photon orbits, dynamics are controlled by a Lyapunov exponent γ, whose role we highlight by computing the first-return map for light rays close to an unstably bound orbit. Despite an exponential e^γ sensitivity to initial conditions, nearly bound rays do not exhibit chaotic behavior. However, as the background spacetime is deformed away from the Kerr geometry, chaos sets in, with its first onset most visible near strongly resonant bound orbits in the photon shell. We display two animations: one illustrating the emergence of chaos near the photon shell, which results in a fractal phase-space structure, and another exhibiting how this chaotic, fractal, self-similar structure is encoded in the first-return map.

In my head, the title of this paper is "Chaos! At the light ring."

The rule in this instance - tile the 4x5 with four different pentomino pieces.

According to this table, all of the pieces are able to get in on a 4x5 tiling except the X.

So - can one prove this is true other than proof by exhaustion?
