Guest Lectures from the Communicating Science Class
Dr. Rob is a scientist and author. To help students understand the impact of communicating science in a manner that enthuses and engages the public, several authors and scientists have weighed in on the importance of good science in social media, fiction and nonfiction.
Toni Weisskopf, Publisher, Baen Books.
Toni grew up in a science-oriented family and publishes science fiction with *accurate* science.  In fact, many of her authors are scientists as well as SF writers.  She talks about the importance of communicating science.
Larry Correia, author
Larry is well known in some online circles for his handling of internet arguments.  He talks about how social media is a spectator sport, what tactics are used by people *losing* an argument, and how your carefully prepared facts may get twisted into something you didn't say.
Gray Rinehart, scientist/engineer & Contributing Editor, Baen Books
Gray worked in, and commanded Air Force facilities where complex technical information needed to be communicated both up and down the technical hierarchy.  He discusses how information content and report styles change depending on who writes, and who reads them. 
Les Johnson, Engineer and Project Manager, NEAS (Near Earth Asteroid Scout), NASA
Les talks about knowing your audience, when to add more technical detail, when to take it out.  He says the most important thing you can do when communicating science... is to read your audience.
David Weber, author
David is known as an author who makes extensive use of Subject Matter Experts.  He discusses *how* to be an expert, what the client expects, how to let it be known that you are willing and available to serve as an expert. As an historian, he also talks about the imperative for scientists to be their own best advocates.
