Evil Ellipsoids and Spheres (Poinsot’s Paper Spaceship #4)
Do you remember how photo negatives looked like? The inverted versions of the most common colors looked so unreal. Hues of orange, violet, or cyan that you never saw in the real world. Happy smiling human people looked like turquoise zombies with an evil grin. When creating this geometric drawing, I haven’t been thinking about…

Poinsot’s Paper Spaceship #0 – The Plan
There was a time before computer-based three-dimensional visualization. There was a time before any software at all. When James Clark Maxwell sculpted thermodynamic functions with clay. When Louis Poinsot described the motion of the gyroscope in terms of three cones embracing each other, boiling down the essence of a free spinning top’s motion. Today, we…

“The Over-All Space-Time View”
… is an expression Richard Feynman had used in his 1949 paper Space-Time Approach to Quantum Electrodynamics. It seems to be one of the earliest publications featuring his famous diagrams. Feynman diagrams are related to interactions of particles, and they look like cartoon illustrations of particles bumping into each other. But they are actually mnemonics…

Circles to Circles – a Series in Progress
When I started creating mathematical artworks with code, the result was a series: I developed a virtual 3D sculpture, looked at it from different viewpoints with my virtual camera … and could not decide which “snapshot” I liked best. So, I panned and pivoted my camera and shot up about 10 different still images along…

Poinsot’s Dancing Cones
I have always loved the physics of the gyroscope. There are so many different mathematical / conceptual / geometrical ways to capture the same thing. Lots of interesting ellipsoids and cones are waiting to be drawn! Here, I am visualizing the motion of a gyroscope free of external forces, involving three cones, following Louis Poinsot.…

Cathedral of Math – Rebuilt!
I have done it! I had repaired version 1 of the cathedral several times, and I finally ruined it. So, I’ve rebuilt it from scratch – to create a slightly different, and hopefully better version. Come back stronger! This took me longer than anything I had drawn before. Click on the images in this gallery…

They Rebuilt Notre-Dame. So Will I!
This has been my Cathedral of Math – a freehand perspective drawing colored with every pen I have! Coloring was partly accidental. I nearly ruined it several times and repaired it again. Read the full story with work-in-progress photos here. It has been so shiny and I liked my “acrylic droplet texture” (This was intentional!)…

Cathedral of Math
Once upon a time, the name of this site was: Theory and Practice of Trying to Combine Just Anything. Today, I am just trying to combine an experiment in code-generated art – the warp core explosion … … with my recent attempts to put spherical harmonic functions – “orbitals” – in perspective: So, I am…

Setting the Spherical Harmonic Functions Free!
I’ve said I put my art on repeat until the bots take over. I foresee a future where a “prompt artist” feeds the vague descriptions of my code art to a bot. The AI will create proper code – replicating what I had done. That’s an issue especially with code art, as there is no…

Lissajous in a Box
Planning for a new project, I am revisiting my first geometric drawings! Looking at my first ever attempt at using traditional descriptive geometry techniques to create an image of the 3D Lissajous figure described by x=sin(t)y=sin(2t)z=sin(3t) t should be a suggestive name for a parameter – reminiscent of time. As time goes on, an imaginary…

Elliptical Collage. Stereographic Haiku.
Once, I have been obsessed with stereographic projection! Circles on the sphere are projected onto circles in the equatorial plane. Corresponding circles are lines on the surface of the same elliptical cone. I created these images with code in 2021. They live in the nether land between of scientific visualization and art: ~ I want…

Negative Art
Or is it positive when a sketch of an inverted photo is inverted again? It was like my re-discovery of Search Term Poetry and Spam Poetry: You think you are oh-so-innovative and leading edge, only to discover that people on the internet have done your thing for ages. With invert art, I am again standing…
