[t3hh0r53]

you need an aerospace degree in order to recite principles of lenses described a thousand years ago?

This is OK but it goes nowhere near where the problems lie. I read about lens design as a hobby (I am a mathematician) and I think it would be more interesting to show a bird's eye view of real design process - why one would want to adjust this surface or why to split an element in two, etc.
