Simon’s Rational Fractions Rule
This weekend Simon told me he came up with this rule that if you take two denominators that make rational fractions when you divide one by those denominators and you … Continue reading Simon’s Rational Fractions Rule

Vector Math in Codea with Box2D. Simon’s own code.
Simon built a program in Codea visualizing the absolute value of a vector:
Line Intersections
Simon shows a project he built using the p5.collide.2D library – he combined two codes from GitHub to make a program looking for intersection points between two lines in JavaScript:
How to double a cube?
We continue reading the Russian adventurous math books by Vladimir Levshin (1904-1984) – see an older post about it – and Simon is often excited about the challenges discussed. This time however, … Continue reading How to double a cube?
Evolutionary Steering Behaviors Game
Note: See the update at the bottom of this post! We’ve had quite a dramatic situation here for the past couple of days, after Simon turned Daniel Shiffman’s Evolutionary Steering … Continue reading Evolutionary Steering Behaviors Game
Simon’s Codea Tutorials and the Arc-Tangent
A set of awesome Codea tutorials that Simon recorded for those who are just starting to program in Codea. Simon ported examples from Processing (java) into Codea (Lua): In the … Continue reading Simon’s Codea Tutorials and the Arc-Tangent
Diffusion Limited Aggregation Tests in p5
Simon was busy with Diffusion-Limited Aggregation, the code he learned from Daniel Shiffman’s Coding Challenge about the generative algorithm “Diffusion-Limited Aggregation.” The DLA visual pattern is generated from random walkers … Continue reading Diffusion Limited Aggregation Tests in p5
Elusive Matrix Math
Many efforts to make a leap forward in understanding Matrix Math last week. Simon was stuck in several vector functions projects (in Python, C#, Java and JavaScript) when trying to … Continue reading Elusive Matrix Math
Simon’s changes to Daniel Shiffman’s Spherical Geometry Coding Challenge
Simon talks about his changes to Daniel Shiffman’s Spherical Geometry Coding Challenge: He has rewritten the code in an object oriented manner. Later he also turned the sphere into an … Continue reading Simon’s changes to Daniel Shiffman’s Spherical Geometry Coding Challenge
More Vector Functions. The Damned Matrix Class.
Simon made another attempt to conquer vector functions, now in JavaScript (in Atom) and got stuck once he reached the Matrix Class, again. He had already tried this in Java, … Continue reading More Vector Functions. The Damned Matrix Class.
Simon’s Changes to the Lorenz Attractor Coding Challenge
Simon explains why he slightly changed Daniel Shiffman’s Lorenz Attractor Coding Challenge: Simon used four variables instead of 11. The Lorenz system is a system of ordinary differential equations, first … Continue reading Simon’s Changes to the Lorenz Attractor Coding Challenge
