OpenAI result shows a fluid obeying Navier–Stokes can simulate any Turing machine
kfountou · x · 2026-10-08
An OpenAI reasoning result (Result 376) demonstrates that forces can be applied to a fluid so that a fluid particle's motion simulates the computation of an arbitrary Turing machine while satisfying the Navier–Stokes equations.
- The construction is explicit, so it can plausibly be simulated numerically
- The poster jokes that NVIDIA/Intel/AMD silicon is now "ancient technology" and we should build computers with fluids
A fun theoretical result, notable for what LLM reasoning can construct mathematically.
