Petr’s Miracle, also called the “Petr-Douglas-Neumann theorem” is a geometric theorem that describes a procedure that can be applied to any arbitrary polygon to always produce a regular polygon with the same number of sides. In response to Mathologer‘s programming challenge at the end of their video on the topic, I created a web app to demonstrate the theorem. Web App The web app has a canvas to draw arbitrary polygons on and visualise the intermediate polygons towards becoming a regular one. The points (what’s the correct grammar here?) coordinates of every polygon is printed below. As explained in the…

Most scientific experiments are designed to test the effect of changing a single independent variable on a single or multiple dependent variables. However, sometimes the effect of simultaneously changing multiple interdependent input variables is required and this is called multivariate experimental design. For example, maybe doubling the amount of one chemical doubles the yield of a reaction but adding a catalyst makes doubling that one chemical triple the yield instead. Multivariate Experiments Instead of a list of every possible combination of variable settings, a Taguchi array (also called orthogonal array) can be used to create a minimal list of experiments…

The Australian Health Star Rating system is a government initiative to label foods with 0.5 to 5 stars to indicate how healthy they are. The calculation is very convoluted so I created a web app to calculate it from nutritional information. As each section of the form is filled out, it also shows the relevant section of the official guide so you can fully understand the calculation process as well as clarify some definitions. The Health Star Rating calculation is broken down into 7 steps: I’ve tested this on a couple of foods including ones that had surprising ratings and…

Space Dandy (not Da Nde) is an anime about a dandy guy in space. Upon revisiting one of my favourite shows of all time, I was excited to learn that there were a series bonus episodes I’ve yet to watch. I was less excited to learn that there were no English subtitles for it anywhere on the internet. So I got to work. Code Explanation The python script I wrote can be broken up into 5 steps: Most tutorials for machine transcription and translation use online services such as Google’s APIs. I loathe online subscription services. Instead, I found some…
