Navier–Stokes equation (2D incompressible), solved live numerically on a discrete grid ρ (∂u/∂t + u·∇u) = −∇p + μ Δu + f, ∇·u = 0 The ink (the white stuff on the left) is added so you can see the motion of the fluid.

Nice live visualization of the equations! Here’s a real-world laminar → turbulent transition in the Isar Canal (single frame vs. average from a 4K video).

Built something similar a while ago for reaction-diffusion patterns!

The contest/prize is rigged though because nature and reality is not smooth. Any thoughts on that?

Where is cascade to larger scales? 2D turbulence is very different from 3D turbulence. The movie says nothing about the correctness of the simulation

Thats interesting as i dont see the way you designed said grid. I happen to know the only determanistic grid that can do this because i built it....the question then becomes why...

How about air over an airfoil, Reynolds number ~10^6

Look at all the ways the 49ers used TE/FB (U) motion to run the football last night. -balanced formation. U motion to run mid zone weak with an insert -Wing formation with U motion to run mid zone weak with a Y slide to block the DE -Wing formation, shift to balanced, U motion into I think Duo with TE going thru and U on DE -balanced formation. U motion to run Duo again -balanced formation. Y motion to run toss crack -shift into wing, U motion into strong toss -balanced formation. U motion into split zone (This one doesn't look right. Curious if this is correct) -Balanced formation. U motion to run something blocked like Duo (I think) but Y is coming from the other side to insert. U on the DE

Quin69 gives his take on the lack of evidence found in Lacari's forensics investigation "What can u go off outside of evidence..if there was evidence saying..there was c p on his computer, accessing websites that had c p on them..those websites didn't have c p on them, his hard drive didn't have c p on them" "Outside of what actually happened, what can u do..it's not as simple as just wiping, u press delete on ur item in computer..u can still recover it, even if u write over it..u can still get fragments..the amount of sh*t these forensics mofos can get is insane" "U have to just go off the facts..I get it, p do bad..m*rder them, I'm down bro but are u gonna do that without evidence?” “Would u put someone to de*th bc there's some stuff that looks bad and looks like they might have done some bad sh*t or would u put them de*th bc oh no we have actual evidence that confirms 100%..if ur gonna accuse someone of this, u better have some serious proof and what I'm saying, where's the proof at bro"

You people only like the Wii U as well because you guys don't like the Switch 1 and Switch 2. If you guys actually were around the era of the Wii U and didn't have nostalgia glasses on, you guys can clearly see how bad the console was. Stop glazing the Wii U. It's performative.
