Simon showed me an interesting paradox that’s difficult to wrap my mind around. If you slice a cone (at a random height), the section is a circle. The chopped-off part … Continue reading The Paradox of the Mathematical Cone
Simon has learned about a beautiful new game from Alex Bellos on Numberphile. The game is called Loop and resembles pool. The pictures below illustrate the layout on an elliptical … Continue reading The game of Loop
Simon is getting faster and faster with the cube. Order a speed cube for his upcoming birthday? So much for “poor fine motor skills”.
Simon has discovered a great new graphing tool: Vectary.com! “Finally I have found something topological,” Simon says. “There is a branch in math called topology. It’s about deforming things. I … Continue reading Vectary.com
Proving a Pythagorean triple. 3Blue1Brown did it in another way, using i.
Simon made a remix of the Numberphile video called “Round Peg in a Square Hole” (by Tadashi Tokieda) and worked out the albraic formula behind the trick.
Simon is very fond of the Magic Tile app, a virtual environment where complex and simpler Rubik’s cubes and other shapes can be solved. He loves the Hyperbolic plane: “Infinitely … Continue reading Magic Tile
The idea comes from a video by Mathologer. Simon sketches a geometric definition of the Euler’s number (e) using integrals. He messed up a little with the integral notation, but … Continue reading Geometric Definition of e
Simon calculating how many configurations are possible in a Rubik’s Square – a flat puzzle he invented, resembling the Rubik’s Cube. He comes to the conclusion that there are only … Continue reading Configurations in a Rubik’s Square
Simon had a blast at #MathsJam Antwerp last night, very proud of his proof for one of the problems (in which he applied an Euler formula), enthusiastic to share his … Continue reading Maths Jam Antwerp on June 19
Doing math everywhere. At the hotel: At The Tower of London: Trying to prove the Wallace Product at breakfast: Coming up with a “spot the mistake proof” at London St.Pancras … Continue reading Doing Math Everywhere
