Re: Re: Re: Using Mathematica notebooks in presentations?
Most presentations I see are done using the beamer class in LaTeX which then produces a PDF that is sent to a data-projector. Graphics are created in whatever mathematics software is favoured, maybe Mathematica, and then included within the tex document. Even movies are quite easily inserted in the PDF using a particular stylesheet in LaTeX. Powerpoint is not especially popular. Images can be "polished" a bit using the superb GraphicConverter package. The final product, the PDF, can of course later be downloaded and viewed by people who don't like Microsoft-specific software.
