> How do you end up understanding linear algebra but turning to youtube videos to understand the fourier transform? As a computer scientist I never actually had a calculus class where we used fourier series. I just ran into them often enough, through stuff like the fast fourier transform for computing convolutions, that I thought I should understand it better. So I googled the topic, and stuff like 3b1b is what came up, and what everyone said were the most intuitive explanations. I eventually did a course on binary functional analysis, and it thought the discrete boolean fourier transform.
