### Unemployment Reading pt. 2… Things to Make and do in the Fourth Dimension

Part two of my current unemployment reading list is… Things to Make and Do in the Fourth Dimension by Matt Parker. I first came across Mr Matt Parker via his numerous youtube videos. They are in the ‘funny math with often a bit of ridiculousness’ category. Through his videos, I eventually made my way to his first book …

### Unemployment Reading pt. 1… The Rap Yearbook

Having a Covid music playlist section shows that I like to (slowly) make lists/groupings of various items. I am hoping that this new list won’t be too long since its length is inversely proportional to my employment success. I do like to read, however sometimes I fall behind with my reading list. Also, I will …

### Project Music #2… Mo Wax Headz 2A

Recently I was able to complete a project related to the Lorenz system of equations (or the Lorenz attractor). It wasn’t too heavy of a project, but I still didn’t want to be that distracted while making it. Hence, I wanted to have some instrumental music in the background since I get easily distracted with …

### 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 …

### Project Music… We – As Is

Recently I completed two different sets of Lagrangian based simulations ([1] and [2]). I believe that Lagrangian based problems are cool and solving them is fun. Anyways, I believe that the song ‘Magnesium Flares’ off the album As Is by We might be a suitable soundtrack to the motion of double and triple pendulums. I …

### 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 …

### Predicting House Prices with the Ames Dataset

This problem is fairly simple to describe… given a bunch of variables that describe the various aspects of a house along with a sales price, is it possible to come up with a mathematical model that can be used to predict future prices based on different values of the same variables? It is based housing sales data …

### Solving the Stigler Diet problem with Gurobi, CPlex, and Glop

First some of the motivation behind this this small project: A while ago I did some optimization work and this project is to ‘awaken some knowledge’ so I can eventually work on some more complicated optimization projects When I did do some optimization work, I had a lot of difficulties with different solvers on the …

### More L-System Fractal Fun…

Every so often, I find doing some ‘recreation mathematics’ a weird type of fun. I know there are better things to spend my brain power on, so I try to limit such projects.  All of these projects are based on L-systems (or Lindenmayer systems) for a few reasons including: 1) they are fairly easy to implement; 2) it’s good …

### Classifying the Fashion-MNIST dataset…

First the overall goal should be mentioned… the aim create a model that will classify small images of clothing items. That is, by learning patterns from a set of 60,000 labelled training images, it is possible to predict the category from 10,000 unseen images.  The MNIST dataset is good as an introductory dataset, however there are some …
