Almost every evening, before going to bed, we are reading books and Simon mostly prefers math adventures. Russian author Vladimir Levshin (1904-1984) published several books about geometry, algebra and math history, … Continue reading Old men from the 19th century
Funny how, even when training some pretty straightforward (and boring) arithmetic or Dutch reading, Simon tries to introduce more complex notions like here, the floor, ceiling and round functions while … Continue reading Looking for math everywhere
Heard Simon give his Russian grandparents a lecture in the playroom, via FaceTime. When I came in, this is what I saw on the whiteboard. Simon proudly said he figured … Continue reading Teaching SOHCAHTOA to Grandmom in Russian
On Monday this week Simon spent hours converting hexadecimals into RGBA values for the 140 colors supported by all modern browsers and creating a color file in Codea. He used … Continue reading RGB Project in Codea using SVG Color Map
Simon wrote a modulus counting program in Processing after we were discussing why 1 % 2 = 1 and why 2 % 4 = 2. He basically told me he … Continue reading Modulus Counting in Processing
A beautiful project in Processing (Java), Simon’s own code, resembling an El Lissitzky painting that you can control and change with the mouse (without Simon knowing El Lissitzky). Resulted from … Continue reading Infinite Line in Processing. Simon’s own code.
Simon translated Daniel Shiffman’s Diffusion-limited Aggregation Coding Challenge into Codea. The coding challenge explores the generative algorithm “Diffusion-Limited Aggregation”, whose visual pattern is generated from random walkers clustering around a … Continue reading Diffusion-Limited Aggregation translated into Codea
Simon was almost done translating Smart Rockets example no. 2 (Smart Rockets Superbasic) from Daniel Shiffman’s The Nature of Code, from Processing (Java) into JavaScript in Cloud9, when he got … Continue reading Error with Genetic Algorithm. What is wrong?
In his recent Live Stream, Daniel Shiffman announced he would make a fidget spinner simulation in the near future. Inspired by this idea, Simon has jotted down some code for … Continue reading Thoughts on Fidget Spinner Simulation
Some more translations, this time from Codea (Lua) into Processing (Java). Ellipse Mode: Blend Modes: Physics Lab tests from Codea:
For my birthday, Simon made me some Fireworks: He made them look even better the following day, by adding trails: The code is Simon’s translation into Lua (the language of … Continue reading For Mom’s birthday
