How much is 13B euros?
Hi, I made this page to contextualize 13 billion euros (or 14): an amount due to Ireland in an EU Apple tax case and all over the airwaves here this week. I use some pretty silly back-of-the-envelope type calculations (the same ones also repeated a lot in Ireland this week!). These calculations aren't especially interesting, but at least they are present: you can see them, and you can change them. If you do - change the 13 billion to 14 billion for example, related numbers will flash with updates. It's an example using calculang[1]: a language for calculations, and an example that focuses on…
In plain words
How much is 13B euros is an interactive calculator that contextualizes the 13 billion euros in the EU Apple tax case owed to Ireland. It uses back-of-the-envelope calculations to show what that amount represents, allowing users to adjust figures and see related numbers update automatically. Built with calculang, a language for calculations, the tool demonstrates the connection between numbers people encounter and the formulas behind them.

Hi, I made this page to contextualize 13 billion euros (or 14): an amount due to Ireland in an EU Apple tax case and all over the airwaves here this week. I use some pretty silly back-of-the-envelope type calculations (the same ones also repeated a lot in Ireland this week!). These calculations aren't especially interesting, but at least they are present: you can see them, and you can change them. If you do - change the 13 billion to 14 billion for example, related numbers will flash with updates. It's an example using calculang[1]: a language for calculations, and an example that focuses on a close connection between numbers that we read or share and formulas/workings behind those numbers. I plan to do a separate Show HN about calculang perhaps when I have more docs and newer playground and gallery together, but Showing this page in case it's interesting, & happy if there is feedback!

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
