In music, the behavior of waves when you play a chord (parallel) versus taking the same notes and playing them in an arpeggio (serial).
The experience is both similar and different.
Or, when you try to swap time and space / space and time with Fourier transforms or other decomposition methods.
Still magical to me.
Someday I want to really dive into Nyquist. It’s so engineering heavy but I should know it.
