Hi,

the idea of this blog is to verify day to day assumptions with simple back of an envelope calculations. Those assumptions could be anything from "I save a lot of money collecting rainwater in a butt", to "Isolating the outside wall of my kitchen reduces my gas bill". We might also tackle some not-so-straight-forward questions like "How to count vehicles per hour passing a point" based on counting vehicles coming towards you while driving a car.

So yeah, it could go anywhere really 😀 Any calculations will be presented in a manner that is easy to understand, and I will link to sources so you can check my calculations. Be aware that I am based in the Netherlands so when I talk about prices they may be completely different for you! So don't assume that any conclusion I might draw from my back of the envelope calculations equally apply to you. Verify, and draw your own conclusions is probably the best bit of advice I can give.

Also my promise: I do use large language models (LLMs) to check my language and spelling, but the ideas and calculations are completely my own. Fight the slop!

Still need to style this blog a bit before publishing the first article, but spoiler alert: It will probably be about bread ...
