Crystallography isn't confined to one specific thing that I've done. There are many components. Many procedures, complex and basic. In 1985, two men -- Herbert Hauptman and Jerome Karle -- were awarded the Nobel prize for Chemistry. And I assisted in making this a possibility, taking their works and theories and leading a crystallography project for proton radiography, which at the time was a relatively new and unexplored terrain. I had my hands in something that ten years later became usable in weaponry. And for something so small to become something so.... destructive -- it was fascinating. And I was there to see it at it's very beginning...

[ Walter smiles at the memory -- lost in a place where science was exciting and new; lost in a past where he thought he had a future. The smile slips from his face after a moment because there's something more curious. Crane spoke as though he had a sound knowledge of chemistry. ]

Forgive me if I'm making assumptions, but do you have a background in chemistry as well as psychiatry?
