Contagious Beliefs–Simulating Political Alignment

This is a simulation that allows you to test how beliefs are adopted based on pre-existing beliefs and how they spread through a population. It is entirely editable, so you can test your own parameters based on your own data or intuitions.

In plain words

Contagious Beliefs is a simulation tool that models how beliefs spread through populations based on pre-existing viewpoints and social dynamics. Users can adjust parameters to test different scenarios using their own data or assumptions, making it useful for researchers, analysts, and anyone interested in understanding political and social alignment patterns. The tool is fully customizable, allowing experimentation with various conditions to see how beliefs propagate across different population structures.

Eigendrum - Draw any shape and hear what it sounds like as a drum▲243
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:…
