How can you communicate anything to anyone? In particular, how can you communicate science (or technical or complex topics) to a general audience? Let's answer this question by looking at how Neil deGrasse Tyson does it.
Smiles are powerful because they are universal: in all cultures people smile to express joy and satisfaction. If there is one thing we can do to improve the impact of our presentations, it’s to smile a little more.
If you want to end strong, plan your presentation with the end in mind. The conclusion is not just the last chronological piece of the topics you covered during a presentation—it is the main theme. Starting with the end in mind means that your conclusion—what the audience has to remember—comes first.
You can have the greatest idea in the world and the slides of the century but if you can’t communicate your ideas, it doesn’t matter. And it’s negligent, because you deny the world of something of great value.
“Slides are slides. Documents are documents. They aren't the same thing […] Much death-by-PowerPoint suffering could be eliminated if presenters clearly separated the two in their own minds before they even started planning their talks.”—Garr Reynolds
Paying attention to the design of a presentation is essential not only because it makes a presentation nicer, but also more functional. Effective design helps your audience better understand your message.
A presentation is a mix of art and science. Although the creation of a presentation is a creative activity, creativity alone isn’t enough—it has to go hand in hand with an understanding of what works and what doesn’t work when it comes to visual communication.
