Here is another excerpt from Krantz for those of you who may have trouble finding a copy: There is an important issue implicit in this discussion that I would now like to examine. A famous counterexample (due to Celso Costa) in the theory of minimal surfaces was inspired by the viewing of a Brazilian documentary about samba schools -- it seems that one of the dancers wore a traditional hat of a bizarre character that was later reflected in the shape of the example. I once thought of an interesting counterexample by lying on my back and watching the flight of seagulls. Whatever the merits of samba dancers and seagulls may be, they are not scientists and they are not mathematicians. Why should fractal geometers be judged any differently? I think this guy just wants to get a little fame for himself. Maybe he's just annoyed that there is so much emphasis on fractals these days (actually he alludes to this in the next to last paragraph where he talks about how getting money to buy hardware to do fractals is easier than getting money to study algeraic geometry). I still think he's a dweeb for writing the paragraph I just quoted. It was completely uncalled for. The editor's note says that Krantz originally submitted this paper to the American Mathematical Society (AMS) and the editor asked for changes (which were made). Upon second review, he decided that it was still too strong and requested more changes and Krantz declined and complained to the Council of the AMS because he wasn't getting published as previously agreed. Krantz had distributed copies of the paper after the first revisions to several mathematicians (including Mandelbrot). It ended up never getting published by the AMS and the Mathematical Intelligencer picked it up along with Mandelbrot's rebuttal. I do think it's good that someone's watching the fractal geometers and not allowing them to get away with just showing pretty pictures but Krantz has crossed the line from being a skeptic to being a jerk. --Bill Davids_on
