Synthical – Like HN, but for Science
In plain words
Synthical is a community platform designed for scientists and researchers to discover and discuss scientific papers, similar to how Hacker News functions for technology. The site aggregates research across various scientific fields and allows users to share, vote on, and comment about papers they find interesting or important. It serves as a centralized hub for the scientific community to stay informed about developments in their fields and engage in peer discussion about notable research findings.

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:…
