Inasmuch as I can follow it, a lot of it seems to be "Well the math seems to work (or can be made to work) so we should be looking for these specific things." Also, it seems like every time an experiment is done trying to prove any of the collection of things in string theory (Or supersymmetry, for that matter,) they always seem to end up not validating what the experiment was trying to prove.

+1. Slides are note cards giving an outline. Some information is easier to explain with diagrams, charts and graphs, or video. Use graphics well. Keep the slides simple with 3 to 7 points per slide (to cater to human short term memory) with about one slide for every one to two minutes. No more than 30 to 40 slides for a one hour session including anywhere from 10 to 15 minutes for Q&A.

and stop after an hour. A presentation which takes more than an hour is fundamentally flawed IMO. If you must go longer take about 5 to 10 minute break each hour.

Build your presentation to how humans operate.

"this is largely a function of screen resolution and visible font size"

Wrong. It is limited by how much and how fast the human mind can absorb. Short-term memory varies from about 3 to 7 items. So I never put more than five items on a slide. First think about how the human mind operates, then pick your fonts etc. If you are finding yourself using smaller and smaller fonts you are not using the slides correcty.
