  1. clean,
  2. simple,
  3. necessary to the story line.

Agreement exists on:
  1. Try to avoid showing tables. Keep fewest significant digits.
  2. Equations intimidate most audience who then "tune out" of the talk. Use with care, introducing the physics of the symbols first. Never change a symbol within a viewgraph or from one to the next.
  3. Lettering on viewgraphs can never be too large, at least 17 point.
  4. Uniformity of style throughout the presentation accentuates and underscores the flow and coherence of the talk.
  5. Figures
    • Clearly label axes
    • Delete all information (curves/words) irrelevant to talk.
    • Explain main points of figure directly on the viewgraph.
