Lorenz attractor amusement with Three.js…

First I should admit the two main reasons why I made this project: I wanted to get some experience using Three.js; that is experience in making a 3D web elements. In the past, I have experimented a bit with WebGL, however I wanted to try out a library that could make 3D development a bit easier …

Some more Lagrangian Problems…

This the continuation to the¬†first set of Lagrangian problems/solutions. While it might be a bit foolish to solve such problems, there are a few reasons why they were done: Its good practice to solve some problems that are a little bit different from the norm. It’s good to be forced to think in different ways …

Lagrangian Pendulum Problems…

This project was more of a large side project than anything else. Its main purpose was to practice making some interactive graphics using the HTML Canvas. Also, it also served to help remember some of the basics with Lagrangian mechanics. Making this project was rather fun. Depending on the workload, more Lagrangian problems will be …

Looking at the SEIR Virus Model…

The SIR Model is a little basic and does not model Covid-19 very well. The SEIR model introduces extra parameters that can make the modelling a bit more accurate. The main change is the introduction of a new ‘exposed’ compartment, so we now have Susceptible, Exposed, Infected, and Recovered (or removed) compartments: There is a …

Solving the SIR Virus Model…

Due to the current covid-19 outbreak there has been a fair bit of interest in virus modelling lately. The models that the media have published/produced vary from the over simplified (and often incorrect) to the complex (with many missing details). I have already looked at numeric simulations using a bouncing ball model, this time a …
