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 […]

Junk the Jargon Podcast

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 […]

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 […]

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 […]

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 […]

Why I don’t make copies of my slides available

As I describe in the Preface to Eloquent Science, the book arose out of a workshop that I taught to undergraduates in Oklahoma. The workshop arose over six years, with what were essentially my lecture notes on PowerPoint slides. The slides were wordy and boring. During the talk, the students had paper copies of my […]

What are your pet peeves?

Appendix B: Commonly Misused Scientific Words and Expressions of Eloquent Science was inspired by a list of incorrect science expressions and annoyances maintained by Chuck Doswell. Many of Chuck’s pet peeves are included in Appendix B. I also surveyed my friends and colleagues about their pet peeves and included many of them in Appendix B. […]

Positive and negative feedback in science: Scientists as social animals

At a recent meeting at the University of Manchester, the keynote speaker was Prof. Helen Gleeson OBE. She gave an informative and interesting history of her career and the lessons she has learned. One thing she said resonated with me (paraphrasing): “As a scientist, you get lots of rejections, but not a lot of supportive […]

“PowerPoint makes us stupid.”

This story is from The New York Times about how PowerPoint has been used (or banned, in some cases) from military meetings and briefings. “We have met the enemy and he is PowerPoint.”
