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!
Catching up with this blog. At the beginning of October, Simon came up with this really cute 5-set Venn Diagram: “You can see that every possible combination of cyan, yellow, … Continue reading Simon’s Logo
Last weekend, Simon started this new school year’s first World Science Scholars course, A Beautiful Universe: Black Holes, String Theory, and the Laws of Nature as Mathematical Puzzles with Breakthrough … Continue reading Simon’s first impressions of this year’s first course with World Science Scholars
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 created a Python program that looks for “squangular” numbers. 36 is both a square number (6×6 square of things makes 36 things) and a triangular number (8×8 triangle … Continue reading Squangular numbers
This is called a Partially-Filled Latin Square. There’s a theorem stating that a partially solved Latin Square can always be completed such that every row has each symbol and every … Continue reading Latin Square Puzzle
The new cohort of World Science Scholars (a World Science Festival program for young math talents from across the world) seems to be more active than last year’s group. Or … Continue reading Year two of the World Science Scholars program
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”
Simon’s back to the Integral Calculus course on Brilliant.org, picking up where he left off in July: trigonometric integrals. His private teacher says that in a Belgian high school, this … Continue reading Back to Integral Calculus
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
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
