Yeah, that step from 1.1.10 to 1.1.11 is a bit dense. I think the key is treating the stereographic projection and the complex structure together — maybe try expressing the components explicitly in terms of y1,y2,z1,z2y_1, y_2, z_1, z_2y1,y2,z1,z2 and see how the cross-product forms. That helped...

Interesting! Maybe also try expanding (a+b+c)3(a + b + c)^3(a+b+c)3 and comparing it with a3+b3+c3+3(a+b+c)(ab+bc+ca)−3abca^3 + b^3 + c^3 + 3(a + b + c)(ab + bc + ca) - 3abca3+b3+c3+3(a+b+c)(ab+bc+ca)−3abc. That might help isolate abcabcabc more cleanly.

Great post, yeah part © is little tricky. I think C1 its voltage from earlier since no current flows with k1 open. C2 does not charge at all i guess, so its voltage stays at zero. That’s how i understand it at least.
