4 DASA 2019-2 I think that Arthur said that we would hope that we would make a dent in the problerm, but | think that one thing we can be sure of is that the problem will make a dentinus of onus, a big one, andl think it's quite necessary. {t's quite an assignment that we have before us, particularly in view of the fact that there have been so few nuclear wars for us to extrapolate from, Huwever, we ought to be dented, I'm guite sure. The conference pattern, for those of you who haven't been here before, ia based on the kind of conference procedure that was devel~ oped in the Josiah Macy, Jr. Foundation, and | have been continuing that firat in ATBS and now with the New York Academyof Sciences, This is to provide a forum for what does not ordinarily take place in scientific meetings, that it, a real dig susston in depth among a group of people who come from very different backgrounds «.f training. We belicve we have made a great rediacovery and we are waiting for the Nobel Prize Committee to decide that Nobel Prizes are given for rediacovericesa, They haven't shown any signs of doing this yet, but we are very patient. The rediscovery is that people communicate with one another not by speaking at but by conversing with. [am sure that all of you are aware of the fact that at most scientific mectings there is no conversation with the chairman as the discussion starts. At the end of the morning he says he hates to interrupt this fascinating discussion but unfortunately we are twenty minutes behind on our agenda and IT must call on Professor so-and-so to make another statement at you. Buta pood active discussion in the form of bull sessions does take place in the corridors, in people's rooms and in the bar, and often tars is the most rewarding part of scientific sessions. So, we thought, why not focus on the rewarding part’? This is what we try ‘odo her, that is, to bring the bull session point of view of the corridors and‘ihe people's rooms and the bar into the conference room. Uf anybody feels very impelled to make a speech at our conferences, badly. we send sim to the bar' s {Laughter| Lhat works not too Other than that, we belic-ee in conversation and, as alt of you are aware, the heart of conversation «s interruption, So the mood of our conferences is, don t speak when cm interrupting. This is the way it will be. TP want to warn our discussion initiators that, in spite of the fact that one of our co-echatrmen nay ticve invited then: to be prepared to tatk tor mot more than half an hour, tn y will be interruptrd.
