what got me started on this was seeing something called the “Ostermeier-Glaberson instability” where a “A vortex ring is stretched by a Gaussian vortex, the vortex string length increases until saturation. These are isosurfaces of minumum superfluid density.” and i started thinking about minimal surfaces, which led me to bubbles (yes, thin film) – and, well, the reason is that I read something somewhere about waves needing a PLANE to form which i’ve been chasing… https://guava.physics.uiuc.edu/~nigel/courses/569/video/index.html

and THAT all stemmed from a fascination a few years ago when I learned about steradians – the reason why waves emanating from a sphere are PLANES – which allows the whole 1 : 4 : 9 :16 inverse square thing… surface minimization…
