Well I also did Fourier and Laplace at uni, but I'm certain it would have been easier to learn if the current explosion of videos on tech topics had happened before I'd gotten there. That 3D of the sums makes a lot of sense, because you need to motivate taking that integral somehow. In my mind I did that, but it's nice to see the video.

Quite a lot of these topics are the kind of thing where you needed to find the explanation that made sense _for you_, and despite universities having a lot of books chances were there were only a handful on any topic such as this.
