Let´s give better scientific and technical talks

The movement toward improved written technical communication has generated little parallel pressure for improved oral communication. Yet the cost of noncommunicative technical talks is large. Attention by speakers to several simple details will result in significant improvements in technical talks. The most important of these details is to present conclusions as close to the beginning of the talk as possible. This simple action will help change a talk from a mystery story to an understandable scientific presentation.
