@joonas_nattila Are we seeing shrinking of the vortex in the animation or a zoom out? 18.2K views · 30 likes · 0 reposts · 3 replies Open on X →

@joonas_nattila With all these discoveries, on the one hand I’m impressed by the feat, but on the other hand, I’m disappointed by the answer. Like is there anything special about this vortex? 90 years and all it took was a vortex? 15.3K views · 53 likes · 1 reposts · 4 replies Open on X →

Visualization of the Navier-Stokes blowup solution: left- and right-handed swirls (blue and purple) wind up while the axial flow (brown) shrinks, but slower. As a result, the vortex core develops a singularity. https://t.co/D3JpdqAOiL
