Roughly Understood is a blog containing articles where we all try to roughly understand topics from programming, physics, maths and more.https://roughly-understood.com/en-ushttps://roughly-understood.com/posts/automatic-obsidian-graph-view/https://roughly-understood.com/posts/automatic-obsidian-graph-view/Obsidian Graph View is an incredible feature that allows for visualizing the relationships between files based on manually typed links. Today we explore a small side project I have created that will emulate this graph view, however it will create the links automatically based on how similar files are.Wed, 26 Jun 2024 00:00:00 GMThttps://roughly-understood.com/posts/dopplin-around/https://roughly-understood.com/posts/dopplin-around/The Doppler effect. What is it? Why should we care? and why cars go VroooOOOmm. There is also a fun animation that gives, I believe, a fairly intuitive understanding of why the Doppler effect occurs.Sat, 23 Mar 2024 00:00:00 GMThttps://roughly-understood.com/posts/foray-into-fourier/https://roughly-understood.com/posts/foray-into-fourier/The Fourier Transform. What is it and how does it work? Today we dive particularly deep into some of the maths and intuition behind one of the most useful algorithms of all time. Bonus, at the end of this article we draw my dog Henry with maths.Thu, 02 May 2024 00:00:00 GMThttps://roughly-understood.com/posts/seeing-doppl/https://roughly-understood.com/posts/seeing-doppl/The Doppler effect, round two: electric boogaloo. This post builds on my previous blog about the Doppler effect and gives an intuitive understanding of how it appears in real-world situations—visualized via animation.Wed, 23 Jul 2025 00:00:00 GMT
