dw, you're not alone in this. Researchers like this are extremely impressive, but it seems like an absolutely massive misallocation of his brainpower. Sure, people can say the same about art/literature/chess/etc., but I would argue that more people benefit from viewing or experiencing the latter than will benefit from working through all 119 pages of this paper. This guy could be doing medical or other scientific research, but instead is working on some contrived problem. Even here, let's assume there is some remote application for a nanobot for targeted drug delivery transiting a capillary... "rough" computational solutions will be more than adequate, especially when taking into account wall elasticity and other variables. I do wonder why some of the top institutions in the world like KIAS are even funding this.
