Decades ago I was working on an algorithm to calculate parameters of my model based on experimental data. I was sort of getting there but the thing was slow and the results were sometimes iffy. I asked my friend whose capacity for complex math exceeded mine by at least an order of magnitude. After few tries he came up with some algo that had solved all my problems with flying colors. His code was very terse and I can't quite understand how his algo works at all. After he had explained its theory to me I realized how genius it was and that I had no chance coming with something like this on my own. I could then "beautify" his code. Way better than trying to fuck with his mind. I am glad people like this exist. They solve problems many other people can't.
