The Chaotic Lorenz Water Wheel

March 22, 2011 | Amateur Science, Math | By: Mark VandeWettering

Doing a bit more reading, I found out that the equations that make up the Lorenz attractor (which are derived from a simplified model of 2D fluid flow with a superimposed temperature gradient) can also be thought of as governing another physical system. Imagine a water wheel, with a number of buckets spaced evenly around […]

Chua chaotic oscillator

March 22, 2011 | Amateur Science, electronics | By: Mark VandeWettering

Over sushi this evening, Tom mentioned “Chua’s circuit”, or “Chua’s oscillator”. I knew that I had seen this somewhere before, but failed to remember that Chua was also the guy who first theorized about the memrister: a circuit element whose resistance is proportional to the sum of the charges that has been passed through it. […]

My own animation of the Lorenz Attractor

March 22, 2011 | Amateur Radio | By: Mark VandeWettering

I’ve been working on a script or two for generating intros for some of my little YouTube videos, and thought that maybe something like an animation of the Lorenz strange attractor might make a somewhat interesting background. A little tweaking, and I produced the following example (only 10 seconds long, and with some Morse as […]
