So, what is stop scientists from making glasses that sees air movements (like if it was water)?

Optical tech hasn’t cracked real-time wearable schlieren.

What signals would air movement be giving off that could be detected without it running into the detector?

Maybe light passing through a moving medium would acquire a phase shift or doppler shift?

>>16711068
particulate matter is everywhere except (and sometimes even) cleanrooms
if something could magically detect the motion of a certain range of particulate sizes along maybe some sort of focus plane...

Like if it WERE water. WERE. Degenerate zoomer animals.

>>16711050 (OP)
In the absence of any detritus in the fluid or contrast with a fluid interface, seeing motion of water is just as hard as seeing motion of air.

No zoomer. Also not a fartmerican, so fuck you. As always, you have nothing of value to contribute, but you stay around to feel smart like a scientist. You are not.

>>16711068
polarization probably

You mean like schlieren imagery?
