I’ve been going through my old Twitter saves, when I came across this one which was no longer available, but which intrigued me! The post is now gone from Twitter, but I found it via the WaybackMachine. Prove that if all the coefficients of the quadratic equation \[ax^2 + bx + c = 0\] are…

One of the earliest laser cutting projects I ever considered was when I was a graduate student: making a stellated dodecahedron. When I got to Harvey Mudd College and had the opportunity to use the laser cutter in the Makerspace for the first time, it was one of the first things I attempted. My initial…

I was going through some old saved tweets during my move to Bluesky, and my favorite tweets to come across were those that mean something different to me know than they did when I saved them. In particular, this tweet from 2021 shows that 2021 JMM Exhibition of Mathematical Art catalog, and little did I…

I saw a post on Bluesky that proposed a problem that I had been thinking about for a long time! I figured that with the help of dictionary and a Python script, I could find the desired examples. One vowel Two vowels Three vowels Four vowels Python code Here’s my quick Python script to help…

Robert Fathauer’s fractal On May 16th, 2024, Robert Fathauer tweeted a wonderful timelapse video of building a white cube fractal, which you can see below. When I tried to learn more about this fractal, I found a Mathematica demo called “Shifting Cube Fractal”. I couldn’t get the demo to work quite properly, so I illustrated…

As I discussed in Part 1, Part 2, and Part 3, I’m going through my old saved tweets and documenting them as I move to Bluesky (@peterkagey.com). Here are the last three of those tweets (all of which had video/GIF embeddings): Alison Martin packing Can anyone tell me more about the geometry of this? Let…

As I discussed in Part 1 and Part 2, I’m going through my old saved tweets and documenting them as I move to Bluesky (@peterkagey.com). Here are four (secretly five!) of those tweets (all of which had video/GIF embeddings): Rafael Araujo with geometric art I think this could be an interesting problem to have multivariable…

As I discussed in Part 1, I’m going through my old saved tweets and documenting them as I move to Bluesky (@peterkagey.com). Here are four of those tweets (all of which had video/GIF embeddings): Matt Henderson on triangle center fractal I didn’t know it at the time, but this Tweet would become the basis of…

As I discussed previously, I’m going through my old saved tweets and documenting them as I move to Bluesky (@peterkagey.com). Here are four of those tweets (all of which had video/GIF embeddings): Peter Huxford on a cubic curve determined by 9 points I posted about this demo on Bluesky. My guess is that it is…

I’ve been off Twitter for a while now, but I thought it would be useful to archive my saved posts somewhere. Here are a subset of my saved posts, which I think are mostly self-explanatory.
