What it does
In the maker’s words, at launch
The functional equation ξ(s) = ξ(1-s) identifies σ with 1-σ. Topologically, this turns the critical strip into a torus. The critical line σ = ½ is the throat. Now treat ξ(s) as a stream function. Its gradient is a velocity field. The flow is automatically: • Incompressible (ξ is holomorphic → Cauchy-Riemann → ∇·v = 0) • Symmetric (functional equation → v(σ) = v(1-σ)) THE CONNECTION Zeta Function Fluid Dynamics ───────────── ────────────── ξ(s) Stream function |ξ|² Pressure Zeros of ξ Pressure minima (p = 0) σ = ½ Torus throat THE THEOREM For symmetric incompressible flow on a torus, pressure minima must lie on the symmetry axis. Interactive: https://cliffordtorusflow.vercel.app/ Why? A symmetric function p(σ) = p(1-σ) can only have a unique minimum at σ = ½. Zeros are pressure minima → zeros at σ = ½ → Riemann Hypothesis. NOW FOR NAVIER-STOKES Beltrami flows (where vorticity ∥ velocity, i.e., ω = λv) have a similar structure. The vortex stretching term—the thing that causes blow-ups—becomes: (ω·∇)v = (λv·∇)v = (λ/2)∇|v|² That's a gradient. Gradients have zero curl: ∇ × (∇f) ≡ 0. No curl contribution → no vorticity growth → no blow-up. THE PUNCHLINE Both problems are: "Given a symmetric structure on a torus, prove things concentrate at the throat." • RH: Zeros (pressure minima) → throat (σ = ½) • NS: Flow (enstrophy) → Beltrami manifold (no blow-up) Same geometry. Same mechanism. Same problem. Interactive visualization: https://cliffordtorusflow-git-main-kristins-projects-24a742b... WHAT I VERIFIED • 40,608+ points with certified interval arithmetic • 46 rigorous tests pass • Pressure minima all at σ = 0.500 • Enstrophy bounded (ratio = 1.00) Repository: https://github.com/ktynski/clifford-torus-rh-ns-proof Paper (18 pages): https://github.com/ktynski/clifford-torus-rh-ns-proof/blob/m... Either I've found a deep connection, or I've made an error that connects two unrelated problems in the same wrong way. Both would be interesting.

OP here: I created this visualization tool as the byproduct of a supply chain class I taught at Columbia. The pedagogical exercise grew into a full blown visualization and paper about global oil trade. The model: The mechanics are the same as the financial network Eisenberg-Noe: Instead of banks, every country consumes oil interconnected via bilateral trading. Shocks propagate throughout the network, depleting oil reserves when bottleneck nodes (such as the Strait of Hormuz) are blocked. Insights: The interesting part is the mechanics of how the crisis unfolds: for example, France receives 0…

- BGBoldly go where Gradient Descent has never gone before with DiscoGrad2024 · github.com · ▲232
Trying to do gradient descent using automatic differentiation over branchy programs? Or to combine them with neural networks for end-to-end training? Then this might be interesting to you. We develped DiscoGrad, a tool for automatic differentiation through C++ programs involving input-dependent control flow (e.g., "if (f(x) < c) { ... }", differentiating wrt. x) and randomness. Our initial motivation was to enable the use of gradient descent with simulations, which often rely heavily on such discrete branching. The latter makes plain autodiff mostly useless, since it can only account for the…

- APA physically-based GPU ray tracer written in JuliaFeb 2026 · makie.org · ▲198
We ported pbrt-v4 to Julia and built it into a Makie backend. Any Makie plot can now be rendered with physically-based path tracing. Julia compiles user-defined physics directly into GPU kernels, so anyone can extend the ray tracer with new materials and media - a black hole with gravitational lensing is ~200 lines of Julia. Runs on AMD, NVIDIA, and CPU via KernelAbstractions.jl, with Metal coming soon. Demo scenes: github.com/SimonDanisch/RayDemo

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:…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
