Western Sand Parallelepiper
Another Math bird in the series! This one was inspired by my 17yr old discussing her math homework of deriving the volume for a parallelepiped. So of course It spawned the thought of parallelepiped sand castles.
Spiraling Vaux’s Swifts
Just like solar eclipses, Vaux’s swifts really are a life experience. Watching them funnel into a chimney in a vortex of flitting feathers is just amazing. I had the wonderful experience of watching them funnel into the chimney at dusk in Salem, Oregon (my home). So here is the next math bird in the series …
Packing Violet Green Swallows
I enjoyed watching the swallows this summer. I couldn’t help but imagine that they were packing circles in their little birdhouse portal. Life is full of such precious moments.
Pileated Woodpecker
Another math bird in the series. I am pretty convinced that pileated woodpeckers communicate in their own form of morse code. I wonder what their frequency is when they are excavating?
Western Tanager
Another math bird in the series. I associate these tanagers with oranges, summer, and warmth. This year I enjoyed seeing them in our woods as I sat on a fallen white oak in the middle of a forest.
Cardinality Cardinal
Another math bird in the series. This one I struggled with what to do and include, feel free to send any comments my way. I am still contemplating if it is really done. I miss hearing cardinal calls from when I lived in the east and watching them out on my grandpa’s farm with their …
Belted Kingfisher
The Belted Kingfisher catches Fish Curves on a King Graph. (This image was updated with a fix after the initial post) Sources: https://mathworld.wolfram.com/KingGraph.html, https://mathworld.wolfram.com/FishCurve.html
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:
i-bis
i-bis (white faced ibis) on the complex plane.
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. Heron’s formula information: https://mathworld.wolfram.com/HeronsFormula.html
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, …
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 spread the Phi-lowers’ beauty everywhere. Side-note: …
Coffee Darkness vs. Daylight
Because it’s true…
Dark Mathemagics
I hope to have a full spell list for all Mathemagics eventually, but a quickly drafted comic will do for now – Enjoy.
Coffee Temperature
If you ever need a piecewise function, this is mine. I redid this from my 2x3in Mathober doodle (I added the overheated peak).
Mathober Complete!
I enjoyed doing Mathober this year and plan to post a new set of prompts for next year. I always feel like I grow as a person with these short, yet focused, activities. Please join in next fall. Thanks to those that joined in on twitter. Special thanks to John Golden who did every day …
Mathober Doodles
This year, I hope to do mathy sketches as inspired by John Golden’s tweet. Initially this post was working off of prompts from another website, and after learning of some controversy, I have decided to rename and recenter this post and month to Mathober. A learner brought up the issues with a trademarked site and …
Klein Bottle Kitty

Kitty’s Toothpick Dream
And for some fun play with toothpicks go here: http://oeis.org/A139250/a139250.anim.html
Cantor Set Kitty Kong
No one wanted to play with kitty…
Unbiased Trade Study (DAR)
No weights were used, the only stakeholder in the process was Kitty, and scores need not be normalized. CMMI Level 5 not achieved… INCOSE engineers may have given an eyeroll…
Kitty is dumbfounded as to why a bird map causes panic…
With mom in chemo and sitting in the hospital 2-4 times a week lately, we have found the lack of access to masks and all the craziness a bit much. Humor is how we cope.

Fractal Dreaming
I had a dream last night in a dream in a dream, so I decided to sketch this one up…
Differential vs. Integral Kitty
I have been reading Infinite Powers by Steven Strogatz as part of a twitter book club and decided to incorporate Fractal Kitty as I go through. This one is from the introduction. I really contemplated playing more with a comic for the Infinity Principle and still may.
