Back in October, Simon got fascinated with this weird system called p-adic numbers (where p stands for “prime”). It’s a system in which you can have numbers going infinitely far … Continue reading P-adic System is used in computers!
I’ve figured out how to do square-roots in binary on Napier’s Checkerboard! I’ve learned how to do addition, subtraction, multiplication and division from James Tanton’s vids. I’ve shown how to … Continue reading Square Roots on Napier’s Checkerboard
Simon is simply mesmerized by the founder of the Global Math Project James Tanton. He has watched countless tutorials by Tanton and frequents Tanton’s Exploding Dots website that features a … Continue reading Base 3/2
Simon has been greatly inspired by the Tech Square website and tutorials on tech drawing. We have also ordered a drawing kit from their company based in Ireland but haven’t … Continue reading Ways to construct an ellipse
Simon has shown me an interesting way to add, subtract and multiply in binary using what is called a Napier’s Checkerboard (or Napier’s Chessboard), something he learned from his new … Continue reading A “quirky way to add, subtract and multiply in binary”
Autumn started with the death of our dear aunt Noor in The Netherlands, which came as a shock. It also brought about the second wave of COVID-19. That second wave … Continue reading Autumn in the skies
Simon showed us this guessing game where we had to guess the correct sequence of cards with numbers 1, 2, 3, 4 while the cards are all flipped upside down. … Continue reading The Perfect Sorting Algorithm
One more project from back in July. Inspired by one of his favorite resources Coolors.co, Simon created a beautiful color palette generator in p5.JS that builds off of a theme … Continue reading A Color Palette Generator in p5.JS
Something else I forgot to post from back in July: Simon explaining linear smoothing and exponential smoothing. You can play with Simon’s smoothing sketch at https://editor.p5js.org/simontiger/sketches/ABdeWZVvs The white circle is … Continue reading Smoothing
We were having a beautiful evening back home in Antwerp, at the harbor. At one point Simon started jotting some calculations on the reverse side of the menu sheet (he … Continue reading Why does everyone get tides wrong!?
A polyhedron is just a bunch of faces connected by edges. All the vertices are closed, so there’re no open bits. So there’s no rule that a polyhedron has to … Continue reading Some thoughts on the dimensions of polyhedra and polygons: How to make a 3D polygon with no area
I defined the efficiency function in JS, I turned the crank and I got this table. So what this is is the efficiency in bases 2 through 8 for the … Continue reading How efficient is a base?
