Back to Python (and C#)!
Simon was preoccupied with vector functions for most of the day on Saturday, compiling what, at first site, looked like a monstrously excessive code in Processing (he recycled some of … Continue reading Back to Python (and C#)!
Treading into Calculus
Simon seems to be setting first gentle steps in Calculus, once again thanks to Daniel Shiffman. In the videos below, Simon talks about minimizing and maximizing functions, the power rule, … Continue reading Treading into Calculus
Simon gets serious with Linear Regression (Machine Learning)
Simon has been working on a very complicated topic for the past couple of days: Linear Regression. In essence, it is the math behind machine learning. Simon was watching Daniel … Continue reading Simon gets serious with Linear Regression (Machine Learning)
Simon explains Linear Regression (Machine Learning)
In the two videos below Simon writes a JavaScript program using Linear Regression in Atom and gives a whiteboard lecture on the Linear Regression algorithm, both following a tutorial on … Continue reading Simon explains Linear Regression (Machine Learning)
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
Translating Car On Terrain project from Phaser.io into Processing
Today Simon spent hours translating this Car On Terrain project from Phaser.io (where it appears in JavaScript) into Processing (Java). He loved doing it in a form of a lesson for … Continue reading Translating Car On Terrain project from Phaser.io into Processing
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
Infinite Line in Processing. Simon’s own code.
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.
