This is where birding meets math.
These birds are often called “upside-down birds,” but maybe they just have no regard for orientation. I enjoyed playing with Boy’s surfaces, Möbius strips, cross-caps, and various Klein bottles for this piece (thanks math Twitter for responding to non-orientable surface requests). I decided on a figure-eight immersion of a Klein bottle.
Indigo buntings are majestically beautiful birds. I had a hard time deciding the direction to go in doodling this one, so I dug up a lot of fun facts: A group of indigo buntings is called a sacrifice, mural, or decoration. Their indigo color comes from the structure within their feathers rather than pigment. These…
I found out that it is World Penguin Day, so I did a quick sketch – enjoy! If you are a maker and want to make a penguin game – try Hex-a-Huddle
Here is another bird in the series – Microcosm Oystercatchers. These are one of my favorite birds. I often see them in the black basalt cobbles on the coast with their fluorescent beaks. I had a hard time with where I wanted to go with this piece initially and went back to gaskets (something I…
Another bird in the series! This one is a little luney. The lunes of Alhazen have the same area as the triangle. Note: Image was updated from the original post to fix an error
All of the great horned owls that have sat with me for hours of my life came to mind. I really struggled with what math peice I wanted to do here. I went with lift. I used multiple images, including my own in composing this. The vortices off the back of the owl are inspired…
These birds utterly amaze me with their gigantic wings, synchronous motion, and high-up flight. They really are a joy to watch in flight, feeding, and landings.
When contemplating a spirally constellation of twin primes, you may ask, “Just how many are there? – Infinite?” The Twin Prime Conjecture would say so.
Another Math bird in the series! These little chickadees make the cutest noise. They have had a brood every year in the neighbors gum tree. When I see their rollercoaster flight, I think of slope fields.
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.
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…
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.
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.
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…
Happy Tau Day! I have created another math bird piece for today with the inspiration of Spotted Towhees on my morning walk.
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.
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 (white faced ibis) on the complex plane.
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
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,…
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:…
