It never seizes to mesmerize me how Simon sees math. So many times has he solved math problems or proved theorems relying on visual, geometric illustrations instead of bluntly applying … Continue reading Simon Shares his Derivatives Tricks: Visualizing Calculus
We’ve calculated the perfect (optimized) combination of biological corn snack (dinos) vs. premium Belgian chocolate eggs. Simon takes it from here: Here’re the assumptions that we used: Both one bag … Continue reading Easter Eggs Optimization Problem
This is Simon’s preferred way of learning math and physics: try to work out the formulas independently. This time it’s the collision formulas which he attempts to depict geometrically. You … Continue reading DIY: Derive It Yourself
Combinatorics problems (each one builds on the previous one): If there’s a sequence of tasks you need to do, and you know how many ways there are to do each … Continue reading Some weekend combinatorics
How fast can a fidget spinner spin? Is it not that fast or can you literally use it as a car wheel? Inspired by Matt Parker, who listened to the … Continue reading What is a fidget spinner’s actual speed, in km/h?
Simon has made a visual about what he calls “three different ways to make a physics simulation”: Blue: Modified Euler Integration (aka Backward Euler Integration); Green: Euler Integration (aka Forward … Continue reading Integration Techniques for Physics Simulations
Really enjoying the chapter on Statistics in our bed-time read, Math with bad Drawings by Ben Orlin, who approaches the subject in the most profound and at the same time … Continue reading How to Lie Honestly
My friend Abhay Kashyap and I have recreated the game AddEmUp! It was a flash game, so you can’t play the original any more. Link: https://addemup.abhayandsimon.repl.co After Adobe first deprecated … Continue reading Simon and Abhay have made a favorite game rise from the ashes
At the beginning of each year, I make a very long, ridiculous video (which I like to call a “magnum opus”). Last year it was the 2048 cookies project. This … Continue reading Simon’s Magnum Opus
Simon has proved that the two methods are exactly the same.
I was looking up the lyrics of The Twelve Days of Christmas song (you know, the one that goes “On the first day of Christmas, my true love sent to … Continue reading The Twelve Days of Christmas: How many Presents in Total?
I sampled 9 points on this curve. The x coordinates have constant increments (equally spaced horizontal coordinates). I then measured the y coordinates — that’s what the numbers at the … Continue reading A quick experiment to prove that a catenary is not a parabola
