There's an interesting panel discussion in New Scientist on the need to revamp the Nobel prizes. It makes sense. The categories have become obsolete as science marches into the twenty-first century. The science awards, for example, are confined to work done in chemistry, physics, and medicine. But today there are all sorts of new fields that didn't exist when Alfred Nobel died in 1896, and a lot of cutting-edge work is being done in neuroscience or evolutionary biology or computer science.
