At that year s meeting Lawrence Livermore s presentations were very well received so well received in fact that managers from Sandia vowed never to be shown up again. When slides are chosen to communicate the images and results of a scientific presentation their design becomes important for the success of that presentation. Typically as soon as a slide is projected the listener shifts attention from the speaker to the screen. When the slide has words that cannot be read the listener is distracted with the question of what those words are. Likewise when the slide does not quickly orient the listener the listener is disoriented wondering what the point of this slide is. If the presentation does not allow for questions or if the listener is not confident enough to ask a question then these questions fester in the listener. Given these two distractions presenters should strive to design slides that are easy to read and that quickly orient the audience. Despite the importance of designing slides that are easy to read and that orient the audience quickly many presenters appear to have designed the slides with the opposite intention. For instance in one recent invited lecture the presenter used a thin serif font Garamond that was hard for the audience to read even for those sitting in the front row. Even more problematic was that the presenter chose type sizes between 10 and 12 points far too small given that the room seated thirty. Causing even more problems was that the presenter chose a color combination of bright red lettering against a white background a combination that would have been difficult to read even with a bold sans serif typeface such as Arial at 24 or 18 points. Worst of all the presenter had placed by far too many words and almost no images on the slides. For thirty minutes this engineer flipped through these presentation
