Workflow: Desmos -> Selva3d -> 3D Printer (in 5 minutes!)

This is a continuation of the workflow series: part 1, part 2, and part 3.  This workflow was done entirely in the web browser and could be done on a chromebook. The only step that requires a more serious computer is sending the file to your 3D printer. Also, writing up this blog post took three times longer […]

Workflow: Desmos -> Inkscape -> Laser Cutter

This is a continuation of the workflow series: part 1 and part 2. Motivation Have students create mathematical art in Desmos and bring that digital art into the physical world using a laser engraver. You can certainly bring any image from Desmos and engrave it into an object using a laser engraver, but this method allows […]

Workflow: Desmos -> Processing -> Fiji -> 3D Print

Note: this post is a more advanced version of the previous post and uses slightly different software. All this software is free and open-source. In this post I’m going to outline how to use a workflow to go from a desmos sketch to a processing sketch to Fiji to a 3D file. The basic idea of […]

Workflow: Daily Desmos -> Desmos -> Madeup -> 3D Print

The seniors don’t go to school on the last day, so I had calculus class on Friday with one student (a junior). We went down to the innovations lab to create things. Here’s what we worked on: Took this sketch from dailydesmos: I had the student work on the solution after talking about superellipses (or […]

Thoughts on the Intersection of Math and Programming

I’ve been interested in the intersection between Math and Programming ever since I taught my first programming course 12 years ago (call it coding, CS, whatever you’d like). I think I’m finally starting to figure it out. Maybe. I was prodded by Dan Meyer and Julia Tsygan to think more in detail about this intersection: […]

3d Representation of Dog Chase

Not what it sounds like. The four dog problem from Steve Strogatz: N dogs start in the corners of a regular N-gon. Each runs directly toward the dog on its left. How far do they run before colliding? — Steven Strogatz (@stevenstrogatz) October 27, 2015 Here is how it was used in my class. Halfway […]
