I don't think it really helps - you're already working in something like a probabilistic formulation. If you want to use a quantum mechanical justification for it then you need to …

It's lost at Boltzmann's "molecular chaos" or "Stosszahlansatz" step. If f(x1,x2) is the two-particle distribution function giving you (hand-wavingly) the probability that you have…

Laser C or Lattice C maybe?

Why does this otherwise excellent series always depict electrons as red and protons as blue when everybody knows it’s the other way round?

The Falcon was a nice machine (I still have one!) although it suffered from the characteristic Atari penny-pinching: still no MIDI thru port (on a machine which was otherwise amazi…

This page was written by Anu Dudhia, who for many years was celebrated by the giant graffiti saying "ANU IS GOD" on the side of Donnington Bridge in Oxford.

Find a style of music you enjoy listening to, then go to a club that plays it, and start dancing. Keep doing that. You might find that your taste shifts a bit over time, and that's…

Great article! Also: > I’ve never heard of a family being divided because its members dance different styles Anyone who believes this needs to go watch Strictly Ballroom (1992) wit…

My favourite example of this is.. Robocop! https://dejareviewer.com/2014/04/29/cinematic-chiasmus-roboc...

Is this the Wayne Holder of Dungeon Master fame?

I remember the Snow Crash MOO! I spent a while there around 1996-1997: it was (despite the name) sort of William Gibson themed - I vaguely remember it being distributed across mult…

Err, no it doesn't - the viscosity in LB is a function purely of the relaxation time (for LBGK anyway). Nor do you need to do any simulation repeats to average out the noise. The m…

Off the top of my head (it's quite a while..), lattice gas models wind up giving you a velocity-dependent viscosity, i.e. the viscosity of the fluid is a function of how fast it is…

They might not be strictly Navier-Stokes but the way in which real fluids deviate from N-S is completely unlike the way in which lattice gas fluids deviate from N-S. Absolutely, yo…

You can see it as continuum-ing up from a CA, or you can see it as a discretization of the continuum Boltzmann equation. What do you mean you don't need Galilean invariance? In the…

I was under the impression that lattice gas methods in CFD were more or less obsolete. They're nice in that they're unconditionally stable and only use bitwise operations, but the …
