What do other specialists do?

AMONG MATTERS OF PRIVATE and professional concern to physicists today are problems that arise from our increasing specialization. One of the most important of these certainly is the way we specialists tend to get so absorbed in our own work that we lose touch with discoveries and developments of colleagues in fields not immediately related to our own. The stimulation to be found in our shortrange intellectual interactions is something we would not want to give up or weaken with dilettantism; still, most of us feel that a constant effort to broaden our general understanding is a professional responsibility, as well as a good in itself.
