I read a comment somewhere that said, "There are no such thing as waves. This is a journalistic invention used to explain the peaks and troughs in graphs to the public". Is this actually the case? Like in the study of public health and viruses, is there no such thing as a "wave"?

Well I haven't been able to find anything that backs up that statement so far... so you're probably right.

Saying that there is a wave on a graph is not the same as assigning a cause to the phenomenon; retard.
A lot of time-delayed compartmental PDE models for epidemiology exhibit dampened oscillatory behavior.

I had a deranged boomer professor for my PDEs course and the numerical part of the course was the most retarded thing ever. He had us calculate stuff by hand on small 3x3 or 4x4 grids.
