The main issue in expanding the prizes is that there's no end to the process. Suppose they add Zoology and Astronomy, as suggested. Then you have a hue and cry to award one for Electronics or Software Design. Physicists might want to specify categories for Optical Physics and Nuclear Physics. Chemists might want the Nobels to award specific medals and prize monies for Physical, Organic, and Colloidal Chemistry. Before long, you'd have 159 Nobel Prizes handed out every year, and the recipients would have to go all the way to Stockholm to pick up their $1.85.
