PDE-Shan is my Chinese-motivated buzz-word for "mountain PDE" (the Chinese name for "mountain" is "Shan"). As the legend tells, Muhamad (Maometto) decided to walk to the mountain because the mountain would not "walk" its way toward him. Analogously, I am working my way to the PDE-zation of variational electrodynamics, an attempt to climb the Schroedinger mountain properly and without making ANY hypothesis besides variational electrodynamics. See the archives paper attached to the first part and the collection of attempts in arXiv:1606.07646v18. As seen by the dates below, I was optimistic about the prediction of how much time it would take me to finish. I had guessed I would start writing the other 50% of the story in September 2016 but it took me until February 2017 to actually start it and another stretch until October to converge in form.
