Also - just finished printing these 1cm connecting blocks that can do the octahedral complex thing.

42 1cm connecting cubes sitting on a 3d printer bed. One batch of 7 cubes are connected together as a "cross" in all 3 axes

Apologies in advance for the alt text not catching the details. Just to excited to not share my Friday night math and music book club at my local bar. Titles and in alt text. WOW!!!!

A messy stack of math and music books at a bar.

1. Center "Lumen Naturae" by Marcolli is off the hook math and art.
2. Upper "Modern Algebra" from 1931 and from E. Noethers lectures. By Wearden
3. Right "Jazz Rags and Blues 1"

A Treatise of Algebra in Three Parts by Colin MacLaurin. In restorable condition $100. At Greenwood Books in Rochester NY. I purchased a $15 copy of Modern algebra 1931 and the owner said - "oh, you may like this one too" #mathsky #MathHistory

WIP - 3D printed 1cm cubes with one peg and sockets on the corners of all faces. Bambu A1 mini is pretty amazing. I have 12 colors on the way...pentominoes and Soma cubes! #tiling #pentomino #SomaCube #puzzle #MathArt

3/4 Are you an adult getting restless bc your kid likes the blocks so much you might miss the whole fair? Try adding up the numbers from 1 to 100. Tactile hint helped but mostly we just talked about how abstraction helps one look past details to see a structure beneath.

Text - What is the sum of the numbers from 1 to 100?
1 + 2 + 3 + 4 + 5 + 6 .... = ?
Maybe we can use abstraction to help. I used abstraction to change this question into a card game. Hint cards are here to help. Talking to people is very much encouraged.

Mid Left - brown crayon scribbling over the answer to the question

Lower Right - 1 cm connecting cubes arranged in vertical stacks of 1,2,3,4,5,6. Shadows cast by extend across the page.

BLOK-TOK is always fun. A chicken, a turtle, an arcade game like Wack A Mole but it has Tetris like pieces(20 questions exhausted) and a little dude doing something like action painting by Pollock. This "thing" slid apart to reveal an ant-eater/lion, a WLG(Weird Lil Guy) and their space ship 2/4

Text from Top -
BLOK TOK
1 build something
2 when your something becomes to you a thing - declare BLOK TOK!
3 It's time to talk about your blocks.
a. Rigorous - 20 questions. You must declare which of the three categories - animal, vegetable or mineral
your thing is and then people ask yes or no question to guess what it is.

b. Also fun - Show and tell - explain what your thing is.

Saturday afternoon at Math On A Stick at MN State Fair with art by @acidlich.bsky.social and the kind assistance of @triangleman.bsky.social Abstraction in Art and Math - Let's Go! Hands on activities demonstrating the practice of abstraction in art and math as a creative process for both. 1/4

Table with two hands coloring a dual tiling with crayons. Lots of pink flower like petal arranged like a six pointed star figure prominently.

Text Box lower Left - Dual Tilings Lizzie KodpuakSeptember 2026
We say a tiling T1 is dual to another T2 when it is possible to set up a
particular sort of one to one correspondence between the tiles, edges and vertices of T1 and the tiles, edges and vertices of T2 such that the inclusions are reversed.
By this we mean if T1 contains a given tile with a certain vertex then in T2 the corresponding vertex is contained in the corresponding tile.

I used graphs and graph theory to "mine" the solution set of the Soma Cube puzzle for "gems." Using a graphical programming language meant for middle through HS students. "Mining the Soma Cube for Gems:Isomorphic Subgraphs Reveal Equivalence Classes" scholarship.claremont.edu/cgi/viewcont...

Six Soma Cube puzzles cleaved to reveal interesting complexes of two and three pieces that can be rearranged, flipped or twisted to complete the cube.

Working on this* and not getting it. I get no visual intuition here that vector i+2j "ultimately lands on (1,3). If I count the grid it still looks like (1,2) Is each y coordinate unit length now 1.5 instead of 1? * www.khanacademy.org/math/multiva... #mathsky #khan #calculus
