I have read through it and left a comment with my thoughts, just to reiterate, I think it is a superbly written hub with some excellent and well written content. My only thoughts on the matter are that you may be putting too much information into one hub, and what level of reader are you trying to attract?
As for the traffic and hits, I think that is just the niche you are in, my quantum physics hubs vary, the Schrodinger's Cat hub gets good traffic, because it is well publicised and in a lot of popular science books. Whereas my quantum suicide article gets much less because it is a more specialised topic. Not sure about yours specifically,although i would presume it is a very specialised search.
