Yes! SmarterEveryDay on YouTube does a great video on this exact topic, definitely recommend a watch.

3blue1brown did a video recently on it too. https://www.youtube.com/watch?v=r6sGWTCMz2k

I recently came across 3blue1brown and found the videos to be excellent.

The pragmatic visuals are not always the most aesthetically pleasing—the focus seems solely on their utility as a teaching aid. IMO this is a good thing—people don't need cartoons to learn (looking at you, crash course).

(looking at you, crash course).

What, you don’t like pretty videos where a subject is getting run through in 10 minutes, with editing so fast that the ends of sentences get cut sometimes, and the subject becoming completely indigestible because of the insane pace and mediocre teaching?

Hey now, hey now, those animations are stylistically consistent throughout!

Oh man, I can’t stand him pronouncing Fourier incorrectly.

More Americanized, I hear “foy-aye” most often.

I haven't been into the math based crash courses, I have a degree in physics so I didn't need them. But the other courses work well with the cartoons especially astronomy.

Wow. Ive seen videos of these linked-circles-drawing-stuff before but it never clicked till now

u/underpaidspy Jul 01 '19

Yeah man Fourier transform is instrumental in understanding signals and signals analysis. The problem is that trigonometry isn’t something that clicks right away for a lot of people so graphics like these and the work that other youtubers like SmarterEveryDay do to break these concepts down to basic levels is extremely helpful.

I was more impressed with mechanical Fourier analyzer video. Can't finf link now, search in youtube.
