What can the scientist who presents learn from Antoine de St Exupery

“It seems that perfection is reached, not when there is nothing left to add, but when there is nothing left to take away.”

(Terre Des Hommes, Chapter 4)

This is so applicable to scientific presentations. The starting point of a presentation is usually the scientific paper. Selection of the contents of the presentation is, for most, a subtractive process, the result of chiseling out and polishing of material until it looks deceptively natural, having “the elemental purity of the contours of a shoulder or a breast”, writes St Exupery.

The presenter knows that naturalness has come to a slide when side details that clothe the basic idea have been removed; when diagrams, transmuted from high density lead to light density aluminum, still conduct information to our resistive brains; when the eye and the ear, in total harmony, never divorce or separate because the visual life of any projected object, as it makes its way to our brain, never extends beyond its spoken life. Once the visual’s verbal amplification comes to an end, the clarity of the visual content is such that lingering on the visual is not required unless the presenter encourages further contemplation to give nascent ideas time to germinate.

What gives an outline that natural shape? It is the title of your talk. Let its invisible hand guide your chisel.
