For simple applications, you have not know too much. In order to understand, you have to acquire some mathematical knowledge from related areas (to Morse Theory).
Thanks, I guess that answers the question. I'll have to spend some time reading to actually understand, though. Any reading/video-lecture suggestions that I should go through besides the links in the article?
