N-Body simulation using WebAssembly
N-Body simulation using WebAssembly launched on September 20, 2018 with 13 votes, #828 of 2,635 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 8 years on.
In plain words
N-Body simulation using WebAssembly is a physics simulation tool that models gravitational interactions between multiple objects in space. Built with WebAssembly for performance, it lets users visualize how bodies move and attract each other based on gravitational forces. The simulation runs in a web browser, making complex computational physics accessible without installation. It's suited for anyone interested in astronomy, physics education, or interactive simulations of celestial mechanics.

Hey HN! I've been working on a book about WebAssembly over the last few months, and it's finally available at http://levelupwasm.com! Why a book on WebAssembly you ask? Well... WebAssembly is awesome (obviously ) but it's certainly not the easiest thing to learn. So I wrote this book as a practical intro to using WebAssembly in your web apps. I would appreciate any feedback!
