Prim Minimum Spanning Tree paper

You can download Prim’s 1957 paper on Minimum Spanning Trees via the attached link. Like many younger students and scientists, I mostly learned about classical methods and algorithms from slides. It wasn’t until I needed to cite some timeless methods that I went back to their original publications. Reading them always feels like travelling back in time, imagining how these ideas emerged in eras so different from our own.

Fun Fourier domain and pattern matching game

less than 1 minute read

Published:

Via the attached link, you can access a Fourier domain pattern matching game developed by Leandro F. Estrozi at the Institut de Biologie Structurale in Grenoble, France. The game features multiple difficulty levels: you place points on a grid to replicate a target Fourier domain pattern. The hidden play mode is to place the points directly, rather than dragging them to interactively observe how the pattern evolves within the given time. This game can serve as both an educational tool for students learning about Fourier analysis and a fun distraction for those further along in their studies or research.

An essay, The Missing Half of Science: Rethink Negative Results

This essay, written with my friends and fellow researchers, examines a major bottleneck in modern science: the loss of knowledge from failed or discontinued research. We argue that these so-called dead ends are often the starting points for iterative improvement, and that preserving them through structured reporting, shared databases and reformed publishing practices could make research more efficient, collaborative and transparent.

Summarised list of Ig Nobel Prizes

Attached you can find a text file where I summarised all Ig Nobel Prizes up til 2025. I like to sneak it into any function I make and distribute so when it runs successfully, the user gets a random row of the file displayed as a fun reward. I got this idea from Gromacs, a legendary free and open-source molecular dynamics software. I will try to remember to update this list yearly.

This could be your favourite colourblind-friendly wide dynamic range colour map

This is my current favourite replacement for jet, or any other ‘rainbow-like’ colour map. It is based on the Okabe-Ito palette, which is designed to be colourblind-friendly, and extended into a continuous map with a pleasantly wide dynamic range. I am mildly offended that this is not already included in Matplotlib as a built-in colormap.
