I guess we have all been there, personally I can relate to both these characters. I can’t remember how many times I thought to myself “Dang it Landau, that step is most definitely not trivial!, you should be more explicit here”.
Also, we have all been stuck in that middle step, not being able to quite figure it out, hopping for that Eureka moment that allows us to get to that beautiful result/Q.E.D. There’s no greater feeling in the whole world that hitting that sweet enlightenment! (wow, even I am amazed at how nerdy that came out 😉 ).
