A good public talk about science should both inform and entertain (in my opinion, any scientific talk should do both!). At FameLab, with three minutes and no PowerPoint crutch, contestants seek the right balance of information and fun. The judging criteria really hit this balance using the three C’s of science communication: Content, Clarity, and Charisma. These C’s form the backbone for any good talk, and we’ve looked at components of all of them before. Here, I want to remind readers that they all fit together.
