What does "humbling" mean in this context?
Does "the eye had to be educated to its rightness" means "the eye had to get accustomed to its right and wrong formats"?
Does "odd sock drawer" mean a drawer of lots of untidy socks? Or does it specifically mean a drawer of socks that no single pair of them have similar colors (each sock in a pair having a different color)?
Duncan says: I spent hours in cytogenetics, and appreciated the scientists’ painstaking approach by doing some of the same exercises – basic chromosome and pairing recognition which their beginners do. There was something humbling about the work because it had to be right and the eye had to be educated to its rightness. Yet there seemed so much variation even with normal chromosomes, it seemed to me the issue of an aesthetic had to be applied to the equivalent of the odd sock drawer.
