This article provides a solution in the R language for Euler Problem 144: How many times does a laser bounce inside an elliptical mirror before the light beam exits it? We can use the solution to this problem to simulate elliptical billiard tables.
How can R be used to conduct qualitative data science? An example analyses interviews with customer advocacy groups and regulators of water utilities using the RQDA package.
Various methods to approximate and visualise the digits of pi using the R computing language for statistics. The apparent randomness of the decimal expression of Pi is a source for beautiful visualisations.
In developed countries, tap water is safe to drink and available for a meagre price. Despite the fact that high-quality drinking water is almost freely available, the consumption of bottled water is increasing every year. Bottled water companies use sophisticated… Continue Reading →
Topology is the silly putty of mathematics. One of the strangest shapes in topology is the Möbius strip. This strip is a surface with only one side. This article shows how the visualise this shape in R using the RGL package.
Many water utilities are implementing or considering digital metering. This article describes analysing digital water meter data using the data science Tidyverse library.
This article simulates water consumption to assist with developing leak detection algorithms. Simulating water consumption helps to develop business tools.
One of my favourite activities in R is using Markdown to create business reports. Most of my work I export to MS Word to communicate analytical results with my colleagues. For my academic work and eBooks, I prefer LaTeX to produce… Continue Reading →
Euler Problem 32 returns to pandigital numbers, which are numbers that contain one of each digit. Like so many of the Euler Problems, these numbers serve no practical purpose whatsoever, other than some entertainment value. You can find all pandigital… Continue Reading →
The netCDF format is popular in sciences that analyse sequential spatial data. It is a self-describing, machine-independent data format for creating, accessing and sharing array-oriented information. The netCDF format provides spatial time-series such as meteorological or environmental data. This article shows how to visualise… Continue Reading →
