“Sometime they’ll give a presentation and nobody will come.” I experienced that again and again while I was a student and researcher. There are conference sessions in which just three people sit in the audience listening to a presentation that is at most mediocre. Only three, because the topic is extremely special and because many presentations recite a bunch of numbers, data and facts.
As students, we can learn a lot of undoubtedly interesting stuff – otherwise we would not have decided to study a particular subject. But most professors do not give much thought to how this material is taught. No wonder with the continuous pressure of publications, project proposals and the day-to-day administrative stuff. The unloved teaching is only the odd one out. But without preparation and training only natural talents may succeed with both instructive and exciting lectures. Unfortunately, this happens far too rarely.
