Description:"This book looks at the presenting scientist from a novel angle: the host. When scientists hosts a talk, the guests expects audible scientific authority from a hospitable visible host, not one that the computer turns into a boring ghost with the consipiracy of sliders whose clarity depends more on how dark the room is than on how clear their contents are." "The host requires a set of skills: personal (voice, host qualities, time control), technical (presentation tools and slide design), and scientific (Q&A, slide content). To build these skills, insightful advise is given to host the talk, craft the slides, and fare well the dreaded Q&A session."
