One of the thinks that surprised me when I first started attending history of science conferences was how many (virtually all) presenters just stand up and read a paper. No visuals. Nothing. Sort of boring. I used to therefore think that in general, scientists were better communicators (at least to their peers). Boy am I wrong.
After this morning, I think I’ve realized that some scientists should never, ever, ever, be allowed to make any sort of presentation, slides or no. They talk to the slides, they mutter, they put too much information on a slide, they try to say everything in 25 minutes (rather than attempting to say one thing well), they don’t realize that you need to speak into a microphone.
For the sake of their students, I hope some of these folks don’t give lecture classes.
