I used to think I was the only one who watches them. In Uni everyone in Physics knows them. I literally made friends by discussing these guys lol.I do watch Andrew Dotson, also 3b1b, pbs space time, veritasium, papa flammy, etc
I haven't actually done Real Analysis so yeah most likely it's harder.Real analysis is just very rigorous from what I’ve heard, everyone doing maths at uni seems to prefer complex analysis
I like Complex Analysis because you delve deep into proofs using Complex numbers and also Surface Integrals etc, which is always interesting.
