Everything here runs in your browser, with the equations and assumptions stated. Drag the reducer to orbit it; every 24 seconds it opens up and shows the load on each roller.
Three scenes, one stage. Each is a real solver with a slider you can move; the numbers are checked against textbook results, and they say so on screen.
f_k(x+e_k, t+1) − f_k = −(f_k − f_k^eq)/τ · D2Q9Lattice Boltzmann flow past a cylinder. Below Re ≈ 47 the wake is steady; above it, vortices shed alternately. The colour is vorticity, nothing is drawn by hand.
Sixteen interviews with people who design electronics, mechanics and optics, September 2026. Three things kept coming back. Quotes are paraphrased and anonymised; the full write-up follows once the people we spoke to have agreed.
Half an hour per footprint, drawn by hand, then fixed again to the house standard. Three days of a three-week project.
Thirty-three thousand pages that don't match the silicon revision. The code works and the documentation doesn't.
No tool for signal integrity, one bench for two engineers, and the truth arrives with the board three weeks later.
