In the russian dance Berezka, women move with steps so short that it looks like they're floating https://t.co/XVTG1KC7Ec [source of the gif: https://t.co/y0hMJU32oI]
Ferrofluid is here poured over-top of a magnet. The magnet is locked within the superconductor's magnetic fields, allowing the fluid to float in midair around the magnet. This is both flux pinning and Meissner effect [full video with more magnets: https://t.co/O3ay0yQ8wx]
Take a 600-cell in 4D with 120 vertices ±v_i, i=1…60
Define F(x)=𝚷_i v_i·x
Stereographically project F from a 4-sphere to 3D, then Fourier-transform from momentum space to position space.
Result: this hydrogen wave function, with energy level n=61.

@Tukyako Hi, I’m not bad. How are you?
I’ve been really busy though, and I have hardly posted anything for a long time! One day I will get around to posting again.
