Neil deGrasse Tyson

At the beginning of this chapter, we read about astrophysicist Neil deGrasse Tyson, who is widely respected not only as one of the foremost researchers on space but also as one of science’s most competent and enthusiastic communicators. Let’s consider how his informative presentations measure up to the concepts outlined in this chapter.

  • Tyson knows his listeners. He understands that while they are not well versed in astrophysics, they are curious about it. He makes abstract topics tangible by using familiar metaphors and examples. When speaking to an audience of fellow astrophysicists, he would not have to take such measures.
  • Tyson uses effective nonverbal communication in his presentations. He uses appropriate gestures, laughs heartily at his own jokes, moves around the stage rather than gluing himself to a podium, and uses a tone of voice that generates a casual atmosphere. His trademark vests—embroidered with images of the cosmos—indicate his enthusiasm for the subject.
  • Like everyone, Tyson has personal opinions and beliefs. But when he is speaking informatively, he limits his discussions to facts. In his discussion of the universe noted at the beginning of this chapter, for example, Tyson explains, “None of this is about ‘belief.’ It’s about ‘what does the evidence show ?’” (Tyson, 2009).
