Spotted Tau-hee

Happy Tau Day! I have created another math bird piece for today with the inspiration of Spotted Towhees on my morning walk.

Space-Pigeonholes Imagined

The Pigeonhole Principle merged with the contemplation of black holes today. I envisioned Fractal Kitty at the whiteboard with this one, but went without the kitty today – enjoy.

“Two-Body” Problem: Barycenter vs Waxwing

After watching the neighborhood waxwings consume their fill of berries prior to moving on, I pondered a different kind of a two-body problem:

Overdue May Update

Well, I am overdue for a post. This year was busy. I taught 11-13 classes per week on top of study halls and homeschooling 3 kiddos. I have found my creative energy slightly depleted. That being said, I got a lot done in May and hope to reset in June. 101 days of code complete! […]

Heron’s Formula

Maybe we should start naming all math formulas and theorems after birds. This one wouldn’t have to change under this new renaming… I do love being able to find an area of a triangle given the lengths of its sides.

Cantor Set Zine

This is Fractal Kitty’s first zine! I was inspired by the public math website. Some wonderful zines from @becky_k_warren and @Ayliean are on there. After cutting the Cantor Set with Kirigami to investigate fraction operations, exponents, and patterns this week with my middle school groups I thought

February Highlights

Coding: On January 31st, I started 101 days of creative coding. After a few setbacks (11 days with no power), I am on track. Please check out 101 days of creative coding on a computer to fully engage with the interactive days. I didn’t want to spam everyone with a daily blog post, but there […]

The 191st Carnival of Mathematics

This is my first time hosting the Aperiodical Carnival of Mathematics. The Carnival is a round of math blogging that shares various articles, posts, videos, and more. Last month was hosted by Sophie the Mathmo and next month will be hosted by Eddies Math and Calculator Blog. I love the tradition of

Probability in the Leaves

I run and see the crows daily. They splash, play, talk, and announce the sunset. I see them in yards flipping leaves together and can’t help but feel that they are calculating probabilities. Of what, I am not sure – maybe the probability of finding a nut, bug, or piece of pizza. No matter what, […]

Folding Origami

Need a pun? This is an origami I-koi-sahedron. This code is from Day 0 to kick off my 101 Days of Creative Code. I will post GIFs to the blog as they are created, but the coding will be done as pages rather than posts ( I didn’t want to spam my followers).

Locomotive Rose Art

The equations used to produce these plots are in the family of rose curves. This particular form is composed of two curves added together. It almost feels like there is some locomotion happening in the visualization, and it is fun to think about the gears and shafts might that make this pattern. r =

Parabolic Beams

I love thinking of parabolas as being formed with a directrix and focus. Coming from a background in trajectory analysis, I find the abstract relationships of the curve to the point and line beautiful. When a light shines through the focus of a parabolic mirror, the light reflected is orthogonal to

Code for Two-Button Calculator

A two-button calculator can only perform two operations (like multiply by two and add five). The Global Math Project is a wonderful resource for math learning and play and has a great resource for two-button problems in this Global Math Project PDF. Another variation of this sort of problem is done

Gold-Phi-nch

This was inspired by my backyard Gold-phi-nches (goldfinches) that cluster on my sunflowers, brighten my days, and provide hours of entertainment. As someone who has been isolated pre-covid, I am so grateful for the joy that birds bring me. I imagine the flocks propagating sunflowers far and wide to

Blue Flames

This code was generated by playing around with one of the p5.js examples. It translates and rotates using parametric equations each frame. Codepen is below (it may not run well on some machines). See the Pen blueFlame by Sophia (@fractalkitty) on CodePen.

Transformed Magic Squares

I got a request from a twitter friend (Sara Resvi) to create a visual for transforming magic squares. A learner can see how one solution is many (or vice versa). Here is what I put together in an afternoon. Click the numbers to change them. Try to find solutions where the rows, columns and diagonals

Parametric Waves Morphed into Unstable Charcoal

Have you ever wished that you had charcoal that is made of particles that randomly leave and come back? Wish the reference frame would rotate so down is up, but not always? Well now you have what you have always wanted – Unstable Charcoal! I created this after playing with a parametric wave visualiz

Laced Reflections

My mind was on snowflakes tonight, which brought me down a rabbit hole of reflections, lace, and play. The code here is simple but fun. Enjoy making snowflakes, lace, stars, or whatever comes to mind. If you wish to fork the code or play it is here. My CodePen is below. Press the spacebar (or […]

Math Finds – Complex Analysis Resource

This is the first in a new category, Math Finds, on Fractal Kitty. I am a believer in growth-mindset and lifelong learning. Peoples’ willingness to share and educate allow for exposure to a plethora of topics and interests. This post is about a wonderful opensource book I found by Juan Carlos Ponce

Dark Mathemagics

I hope to have a full spell list for all Mathemagics eventually, but a quickly drafted comic will do for now – Enjoy.
