a homeschooling blog about Simon, a young mathematician and programmer, and his little sister Neva. Visit https://simontiger.com
Simon explains strong and weak tree sequences and reveals the greatest finite number used in mathematics: TREE(3), a lot larger than Graham’s number. The TREE sequence is a fast-growing function arising out … Continue reading Larger than Graham’s number!
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.
To solve the problem, Simon chooses not to look up what the derivative of a tangent is but work everything out from scratch. He generally doesn’t like rote learning but … Continue reading Simon differentiating 3tan(2x)
The number of collisions between two objects equals a number of digits of Pi. The code on GitHub: https://github.com/simon-tiger/Pool_Pi Simon writes: From where I got this I called this sketch … Continue reading Simon’s code for an intriguing problem from the 3Blue1Brown math channel
NYU’s Associate Professor Daniel Shiffman quotes Simon during a Coding Train live tutorial from New York about Fourier Transform Drawings on 16 January 2019. Simon was participating via the Slack … Continue reading Daniel Shiffman quotes Simon’s thoughts about complex numbers
We were reading a bedtime story, from the book “17 Equations that Changed the World” and Simon told me about how a computer disproved Euler’s Conjecture. I was surprised at … Continue reading Euler’s Conjecture
Simon explains why our modern satellite navigation (the Global Positioning System or GPS) is a great experimental proof for Einstein’s relativity theory and what would happen if the software calculated … Continue reading Newtonian GPS would place you on the wrong planet!
This is almost a magic trick that Simon borrowed from the Actionlab channel. Will the wooden block fall down on the ground once you let it go? Obviously, it will. … Continue reading Physics Experiments: Will the wooden block fall?
Simon trying to build a device that allows to carry a cup without spilling the liquid, i.e. with a minimum lateral acceleration to the cup. Extra footage of us having … Continue reading Physics Experiments: No Spill?
Simon talking about his favourite infinite sum at the circular room known as the “pi room” at the Palais de la Découverte (“Discovery Palace”) in Paris. Inscribed on the walls … Continue reading Salle Pi
The video below is part of Daniel Shiffman’s livestream hosted by GROW Le Tank in Paris on 6 January 2019 about KNN, machine learning, transfer learning and image recognition. Daniel … Continue reading Simon took part in a Coding Train livestream in Paris!
Simon: You can derive the speed of light from Maxwell’s equations. Me: Because they used to think it was infinite, right? Simon: Maxwell’s equations aren’t invariant to the Galilean transformation, … Continue reading About Maxwell
