An Overfull Slide With A Long Title Nobody Is Going To Read In Time Anyway

Well, see, overfull slides are a distraction from the talk itself, and do not help ANYONE. The time you need to read this slide you cannot use to listen to the speaker, who is going to tell you something else (because, well, the other things are on the slide, aren’t they?) So, you miss stuff, and maybe

important stuff. On the other hand, if you listen to the speaker, you miss the stuff from the slides, which will not be repeated, because . . . I think you get the point.

To maximize confusion,do not use overlays, because this would actually help reading the slide. Just put everything on one slide, talk while the slide is on screen (but not too long!) and then go on. Nobody will ask questions about your talk then, that’s guaranteed.

Using Itemize to Decrease the Auditorium’s Attention

I If you have to use itemize, make sure it does fit on the screen

I Better make slides with too few words than with too many.

I Don’t make long entries in the itemize environment, this will just confuse anybody who wants to read what you have on your slide. Anyway, presentations should not be summaries of your papers, should they? Well, then! And of course, long sentences on your slides are always a bad idea.

I Don’t use nested itemize environments

I They won’t help!

I And won’t clarify stuff

I Important stuff

I Which may be relevant!

I But nobody is listening anyway!

I But instead is checking emails . . .

I Or is surfing the web

I Or is doing other (not so important) stuff

I But you don’t have to mess with background colors to make things unreadable!

I Because there is a plethora of bad colors you can use in presentations

I And apart from that, it may just look ugly . . .

I But jumps may sometimes be hard to avoid

I Mostly due to the use of \only

I In TikZ, don’t only do

\path<+->[draw] ...

but instead do something like

\onslide<+->{

\path[draw] ... }

or use \visible

I Useoverlayareaandoverprint for dynamically changing slides

I Last resort: a table is stable!
