So there's this thing called a Fourier series...
Basically any wave can be created by adding together individual frequencies, and with some fancy math it's possible to go the other way with a Fourier transform and get how loud every frequency is (like is displayed in a spectrogram).
I think the real black magic is in how our ears and brains can decode the mess of information coming in and identify meaningful patterns.
The free market will decide it's actually more profitable to shut down bus service entirely and pivot to helping ICE transport bus loads of "illegal immigrants".
