Let there be stoning!

Thanks to Bogdan Antonescu for pointing out to me the latest entry in Garr Reynold’s Presentation Zen blog. It discusses an article “Let there be stoning!” written by Jay Lehr about bringing an end to incredibly boring speakers. If only more speakers would follow this advice: The average conference paper is 20 minutes in length. … read more

Booed for Keeping Speakers on Time

I was session chair at a recent meeting. The meeting was running behind, and they crammed a speaker from the morning session into mine, effectively taking away my 15 minutes of free discussion time at the end. Each slot was 20 minutes long, which as most experienced speakers would infer means that you get 15 … read more

Monkey See, Monkey Do

In writing my book and questioning the “standard” approach that people have used to give scientific presentations, I have often wondered if people stick to convention because that’s all they’ve seen. They see an outline slide or a meaningless “thank you!” slide and think, “Yeah, that’s the way to do it right.” The question is … read more

When should you script your talk?

For people with little experience in giving public talks, I recommend two things. First, practice, practice, practice. The more you rehearse your talk, the more confident you will be and the more likely you will give a good presentation. How many times is enough? That depends, but if you are giving your first conference-style presentation … read more

I’ve appeared in the University of Manchester Junk the Jargon Podcast (Junkcast). You can listen or read the transcript here. In this Junkcast, I talk about how to engage an audience, giving some examples from my and others’ presentations.

English Communication for Scientists

The journal Nature has on its Scitable page a link to an online book English Communication for Scientists by Dr. Jean-luc Doumont (that’s him on the right). I haven’t read through it all, but it seems to have mostly good advice, albeit a bit short. The online book has six units: Communicating as a Scientist … read more

Is your “Outline” slide really needed?

If you are giving a scientific talk at a conference (e.g., one that lasts 10 minutes), do you really need an outline slide? Do you really think the audience needs to know what the basic content of your scientific presentation is going to be? Even in longer talks, is such a slide really needed? When … read more

Do you end with a ‘thank you’ or ‘questions?’ slide?

If you do, you are wasting a valuable opportunity to leave your audience with your take-home message. Of course, you should express your appreciation to your audience by thanking them for their attention, but I am not impressed by a speaker who thinks that a slide is the way to express such sincerity. Likewise, everyone … read more

Take the Poll: Color Schemes in Presentations

In Eloquent Science (p. 279), I made the argument that light-colored text on dark-colored backgrounds was preferable to dark-colored text on light-colored backgrounds for three reasons. 1. Red lasers (especially if the laser light is weak) may not show up well on white backgrounds. 2. Slides with white backgrounds lose contrast if the room is … read more
