drifting through an afternoon of iridescent colors and ever-shifting radiance. my contribution to this month's indieweb carnival, hosted by @fractalkitty.com: second person birds. wavelight.ws/blog/2025092... #secondpersonbirds #nature #birds #hummingbird #indieweb #indiewebcarnival

A perfect square day, but a rectangle: www.desmos.com/calculator/4... #desmos #mtbos #mathart

3²/4²/5² is the perfect day for arguing about best proofs of the Pythagorean theorem. An incredible thing about Euclid's proof is that it applies to the area of *any* similar figures drawn on the sides of a right triangle. 🧮

Some of you have probably just been out of your minds in anticipation for this year's Mathober list I broke out the random number generator, word list, and channeled curation energy and delivered Blog: www.fractalkitty.com/mathober-2025/ Mathober: mathober.com #mathober #mathober2025 to share

mathstodon.xyz/@fractalkitt... Math thoughts while running:

Next week has a "Pythagorean" day on 9-16-25... so check out my "Pythagorean Party!" blog w/ technology activities & visuals to celebrate pythagorean theorem & related concepts. karendcampe.wordpress.com/2025/07/30/p... #MTBoS #iTeachMath #T3Learns #geometry #MathSky #MathsToday #RecreationalMath

it is like you stand just to remind me, nudge me, days, loops, through the years

After @glitch.com shut down hosting, the Permutation Group Visualizer is back up at permutation-groups.netlify.app!

On Friday at Noon (EDT) I am giving a talk in the New York Combinatorics Seminar. The title is: "Mathematical illustration through a combinatorial lens" in which I share my decade-long journey as a mathematical artist and jewelry maker and how it intertwines with my combinatorics research.

Content for the Carnival doesn't have to be a blog post - it can be mathematical videos, social media threads, or whole websites - as long as it's been produced this month. Submit at aperiodical.com/carnival-of-mathematics

Played with the BEST theorem a little yesterday: #math #besttheorem #eulerianCircuits #circuit #euler

Do you make #MathArt? UIUC is commissioning an art installation for their new mathematics common room! illiniart.web.illinois.edu 🧮

If you're in the Portland area, I'm speaking in the Reed math colloquium this Thursday, and I'm offering a bounty! events.reed.edu/event/copy-o... 🧮

Beautiful piece that brought a moment of reflection in the middle of the day. Lovely. "we marvel. the quiet songbirds perched above us are a little closer to the faint stars and crescent moon peeking from behind silver billows."

to be a bird in the last moments of twilight, when painted sunset skies are flecked with star droplets, and feathers gradually blend with quiet darkness.

I am printing a noperthedron pencil holder :) #mtbos #mathart #noperthedron

At @recursecenter.bsky.social Annotated Turing group we talked about diagonalization. I made a joke-then poster/bumpersticker always a fun conversation-what is real? what can we express?what can we compute? #realNumbers #birdsarentreal #math #mathart #mtbos #recurseCenter #diagonalization #cantor

Only a few more days until submissions close for this month's Carnival of Mathematics. Submit your favourite internet maths: aperiodical.com/carnival-of-mathematics

A new post on To Ground Link: toground.link/caressed-by-... #blog #bearblog #indieweb

A new post on the math blog! I built a couple of toys to play with as well. www.fractalkitty.com/inquiries-we... #indieweb #math #colorings #graphTheory #triangles #inquiry #mtbos #iteachmath #mathtoys

I made a rough draft of a Ducci sequence toy: inquiries.link/tools/number... In the process, I now have 0, 653, 1854, 4063 memorized. Also (diffy squares) (see mathforlove.com/2020/03/diff...) #math #mtbos #inquiry

I played with paint today. The packing radii for n-dimensional spheres is $/sqrt{n} - 1$ and spiral of archimedes hypotenuses follows sqrt(n), so I subtracted 1 from each hypotenuse and then added color.

The @puddingviz.bsky.social has a new post! Onions + Math - I'm so happy I could cry. pudding.cool/2025/08/onio...

Happy HTML Day! Get out there and make the internet a little bit more fun! ✨

HTML.energy day wooo! I went to the event hosted by the-sudo.net at the @virtua-gal.bsky.social. The site I slapped together is a random collective noun generator - lots of people contributed nouns at the event - we were an "unordered list". nouns.website #htmlday2025 #htmlday #recurseCenter

marvelous longform nature poetry. an essay on embodying terrestrial glory, a cloudscape all the more wondrous for its impermanence.

My "Math, Revealed" series is freely available to anyone -- no paywall! -- in the thread below.

A new inquiry post on my fractalkitty blog: www.fractalkitty.com/inquiries-we... I started making a separate site for tools as I work on this series, and hope to share more soon. For now, it is under construction. #mtbos #math #iteachmath #inquiry #interactive

morning meditation #math

@fractalkitty.com After today's FrESH I played with your haiku explorer so I could find words by matching. Filters match from string start. codepen.io/artlung/pen/... #JavaScript #Haiku #d3 #IndieWeb

Continuous, yet discrete roots trip me up.
#mathThoughsWhileRunning

Coded straight lines (38minutes of code) with RC creative coding group prompt. I could go on forever with curves, but stopped myself. www.youtube.com/watch?v=dpOS... codepen.io/fractalkitty... #rc #recurseCenter #codepen #creativecoding

Codepen asked for spirals - did I miss any? (no I didn't do ulam - should I?). codepen.io/fractalkitty... #codepen #spirals #codepenchallenge #cpc-spirals #math #spirals #mtbos

Drafted a 3rd inquiry activity for D3 and D4 play with flips and rotations. I am hoping it's not to dry. I'll read through it again tomorrow. #mtbos #dihedral #grouptheory #iteachmath

During the last week of school, I had some students ask me if I had any coloring pages they could have. I didn't, but I did add "make mathematical coloring pages" to my to do list for this summer! mathequalslove.net/geometric-co... #mtbos #iteachmath #mathsky #edusky

The #geogebra #tessellation book was getting unwieldy (75+ applets) so I tried to organize it... www.geogebra.org/m/CUdKaHeC

I have a new blog post for an inquiry activity on modular arithmetic with The Fibonacci Sequence. There is a musical toy for listening to patterns. I regret not drawing a pigeon for this. www.fractalkitty.com/inquiries-we... #mtbos #math #iteachmath #pigeonhole #fibonacci #pissano

I am starting a new series on the blog for inquiries in math. I posted the first one today: www.fractalkitty.com/inquiries-we... #mtbos #iteachmath #circles #graphtheory #math

Hi all! I left my Senior Producer role at Brilliant in Oct. and just finished a batch at the Recurse Center. I'm now exploring opportunities. If you know of places doing meaningful work, I'd love to hear about them. I enjoy solving problems, being creative, helping others, and education. #mtbos

I wrote the first post on my personal (not-as-mathy) blog: toground.link/deep-in-the-... #indieweb #renewal #pnw #bearblog #blog #nature #photography #writing
