Simon tried to predict the weight of some of his constructor pieces by calculating their approximate area. He later also successfully predicted the weight of a binder clip through calculating … Continue reading Predicting weight by calculating area or center of gravity
Simon made these Reuleaux triangle from red cardboard. They are formed from the intersection of three circular disks, each having its center on the boundary of the other two. Its boundary … Continue reading Shapes of constant width
Simon (and Neva as his assistant) experimenting with the topology of a paper strip, filming their (almost magical) tricks on a slow motion camera: Inspired by Tadashi Tokieda’s geometry and … Continue reading Topological trick in slow motion
Simon loves various L-Systems, sets of rules transforming letters into geometric structures. He used to program these, this time he recreated some by hand.

Simon has been into making various hexaflexagons, inspired by the Vihart channel. It was tough at first, but later the same day he didn’t need any help anymore and flexed … Continue reading Hexaflexing
Simon loved the optical illusions scattered around the town.
https://youtu.be/dYBZXFW4bsg Simon is working on a project that will involve constructing the Archimedean solids from paper pieces that he programs in Processing (Java) and prints out. In the previous video, … Continue reading Simon’s Archimedean Solids Project
Simon prepared 100 2D shapes to make over 100 solids yesterday. He started with the easy one that he had built hundreds of times before, when he was much younger … Continue reading Back in Shape
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 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.
