Heat maps are awesome

I love heat maps - they're a great way to show certain types of data in a really visual way. While typically thought of as being used to show the density of something, we can be quite creative with what density means. I look at a couple of helpful visualisations I've used in this post! … Continue reading Heat maps are awesome →

A perfect matching of complex roots

As part of a placement earlier this year, I was given two sets of functions to play with. The first set was implemented in both MATLAB and FORTRAN and formed a root-finding algorithm. The second was implemented in only MATLAB but promised shorter running times and greater accuracy. The task was to compare the two … Continue reading A perfect matching of complex roots →

Processing big data from small experiments

I thought I’d share a post about a problem we faced in the most recent project I worked on. The aim of the project was to calculate certain properties of fluids which were being forced through a jet. This involved processing terrabytes of data, most of which was redundant as we only cared about the … Continue reading Processing big data from small experiments →
