@El'endiaStarman Playing through SnakeBird with that video in mind makes me appreciate it a lot more. I've been stuck on level 20 for ages:
I've probably spent like 40 minutes trying to solve it in total. I finally found the assumption that I needed to break, and it's one of the most satisfying things
@flawr Taking a break and looking at it again made everything more clear. I completely understand it now:
i ^ i
exp(i * ln(i))
---
ln(i) --> e ^ x == i
e^x == i
x == i*pi/2
cos(pi/2) + i sin(pi/2) == i
ln(i) == i pi / 2
----
exp(i * i pi / 2)
exp(-pi / 2)
e ^ (-pi / 2) == 0.207879576
