This picture looks like it was taken through a dirty window (I intially thought it might be a reflection of a blackboard) - in other words its not really in focus at all - 4
This is an interesting idea for a shot. The black and white of the chalk and board have great graphic potential. Sadly, it is quite a bit blurry. I suggest using a tripod next time. Even a litte $10 table model would make all the difference. Keep trying!
on topic ... maybe if I knew more about math I'd get your point ;) -- unfortunately I don't so there's no main or compelling element for me to relate to-- sorry
