Magnitude of a 3D vector
Here Simon explains how to calculate the magnitude of a 3D vector. This is something he partially figured out on his own and partially learned from Daniel Shiffman’s tutorial on … Continue reading Magnitude of a 3D vector

Old men from the 19th century
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
Looking for math everywhere
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
Teaching SOHCAHTOA to Grandmom in Russian
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
Modulus Counting in Processing
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
Algebra: Functions
Simon loves functions. He hasn’t ever studid them in Algebra, but comes across functions regularly in programming. This is what he came up with Wednesday: I showed Simon that … Continue reading Algebra: Functions
Minimum Spanning Tree in Processing
Simon’s version of Daniel Shiffman’s Minimum Spanning Tree tutorial: Simon translated it from JavaScript into Processing (Java), “a much more complex project than the circles with no overlap!” A minimum spanning … Continue reading Minimum Spanning Tree in Processing
Cellular Automata in Arduino
Yesterday Simon spent the whole day studying the concept of Cellular Automaton (CA), a discrete model of a system of “cell” objects used in physics, math and theoretical biology. He … Continue reading Cellular Automata in Arduino
Buzzing Bee translated into Lua (Codea)
Simon really enjoyed Daniel Shiffman’s “buzzing bee” (from the Graphing 1D Perlin Noise tutorial) into Lua, the language of the Codea app.
Smart Rockets Coding Challenge translated into Processing (Java)
And here is Simon’s translation of Daniel Shiffman’s Smart Rockets Coding Challenge into Processing (Java). This challenge (originally in JavaScript) was about implementing a genetic algorithm from scratch and create “smart rockets” … Continue reading Smart Rockets Coding Challenge translated into Processing (Java)
Perlin Noise Combined with Sine Wave Translation into Processing
Simon translated Daniel Shiffman’s Graphing 1D Perlin Noise tutorial into Processing (Java). The project involved combining perlin noise and sine wave: He also attempted to translate Perlin Noise Flow Field … Continue reading Perlin Noise Combined with Sine Wave Translation into Processing
Polar to Cartesian converter (Simon’s own code)
Simon built a Polar to Cartesian converter (Simon’s own code). You can enter the radius in pixels and the angle in degrees, click “convert” and you get the coordinates in … Continue reading Polar to Cartesian converter (Simon’s own code)
