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 objet, 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.

I are delighted to feature a new guest on our podcast: Dr Rao Machiraju. Rao and I belonged to Apple’s Advanced Technology Lab in Cupertino California. He now heads his own company, REQALL, working on a fascinating product: memory recall enhancement tools. Rao is a master in the art of presenting. Today, he reveals his favorite ways to handle questions during the Q&A that follows a talk.  They depart from the conventional ways, as you will soon hear.

Presentation Traps 10 – The room trap

Doomsday!

Your phone rings. The receptionist tells you the Japanese visitors have arrived. You take the elevator down five floors to the ground floor where the two meeting rooms are. Many people use them, and the furniture frequently gets changed to fit the requirements. You asked for a simple U-Shape table arrangement to accommodate 8 Japanese visitors in the “Small 1″ meeting room. As you welcome the visitors, you are given a handwritten note from Suzan, the facilities manager, informing you that the room has been changed due to unforeseen circumstances and that you are now presenting in the “Big 1″ – the tables have been arranged in U-Shape as requested.

The only problem is that the “Big 1″ is a room for fifty people. The visitors come in and fill in half of the left side of the U-Shape – the side exactly facing the lectern… but perpendicularly. All heads turn right to face you, twisting necks; People bend their torso or move chairs back and forth to get a better view of you. Furthermore, last night you downloaded your presentation in the computer of the “Small 1″ meeting room -and your USB drive containing your presentation is five floors up.

The “Small 1″ room has a simple audio out cable that fits into the presentation computer and is always on. The “Big 1″ has an audio mixer with multiple BNCs,mini stereo Din, XLRs and Mike jacks. The mixer is turned off, you need computer audio out, and the labels on the mixer are totally cryptic. On top of the lectern hiding the presentation computer, is a brief note that suddenly explains why the “Small 1″ is taken and why the mixer is turned off: the room’s computer has been removed for repair.You then realize that you had assumed that each room would have a working computer and therefore failed to tell Suzan that you needed one.

As you are wondering what to do, the maintenance man appears with a tall ladder with the intent to change a broken light bulb. He had been told the day before that the room was not occupied since the computer was down. All the Japanese heads turn towards him, then back to you… You’ve reached bottom, or so you think.

A drop of water falls on your head. You look up. All Japanese heads look up,  and everybody discovers at the same time the fresh water stain probably caused by a leak in the lavatories upstairs. You return your eyes down to your guests, you raise your hand to apologize, and in the process knock down an empty stainless steel jug from which a large cockroach escapes, flying out and landing on the chair occupied by the head of the Japanese delegation. You swear. They hear you. Now, you have really reached rock bottom.

OK, so maybe I overdid it, but a presentation room is a dangerous place, full of potential unsuspected problems. Can the presenter prevent them all? No, but the presenter can be prepared for them all. What went wrong?

1) Never assume anything when it comes to the presentation room.

2) Always have a copy of your presentation with you, on you.

3) Rehearse in the presentation room the day of the event.

3) Be ready to do an impromptu presentation that does not rely on the computer (a flip chart will do).

4) Never put the blame on anyone because something goes wrong. You will be regarded as an incompetent person trying to discharge his/her responsibilities on others.

5) Keep control of your mouth and avoid foul language – whatever the circumstances.

This said, you don’t need to walk around with a large can of insecticide deforming your bulging trouser pocket… just in case. And when the man with the ladder comes, don’t ignore him. Recognize his presence, and ask him if he would not mind getting an umbrella, and holding it upside down above the leak while on the ladder, to avoid you being wet during your talk. By that I mean, think on your feet, and weave the circumstances in the tapestry of your talk.

Presentation traps 9 – the rehearsal traps

Try and find out what is wrong with the five situations described below.

1) Sylvia is in the University library facing the screen of her laptop. She came here to have a chance to be quiet and rehearse an important upcoming presentation. She methodically looks at each slide, and silently (she does not want to disturb her neighbors) rehearses what she will say.

One does not rehearse silently. You need to activate the pathway between your brain and your speaking apparatus, open wide a channel between your inaudible thoughts and your audible voice. For that, you need to rehearse at full volume, using the full range of expressive capabilities offered by your vocal chords. A library is not the best place to do that. Finally sitting is not the ideal position for rehearsing. Standing is.

2) Prasad is using the notes section of his PowerPoint presentation and writes down the talk he intends to give. To make sure he will not spend too much time speaking, he sets himself a target of a maximum note length for each slide. Then, sitting in front of his computer, he rehearses by reading the notes aloud, memorizing as much as he can in the process.

Only radio and TV professionals know how to write for the ear. Unless you are trained in the arts of oral communications, memorizing such written notes will make your speech sound unnatural. The audience knows that people don’t speak like that. Your words will be too complex, your sentences too long, etc. Finally, what dictates the time one spends on a slide is not defined by the size of the note section, but by the amount of information displayed on the slide. And remember point 1: stand up to rehearse.

3) Xiao Hong is standing a few meters away from her computer screen looking straight at it. She has entered the slide show mode and starting with the title slide, rehearses aloud keeping eye contact with the screen, moving from one slide to the next using her favorite presentation remote.

This looks like the perfect picture. What could possibly wrong with it? You should not rehearse while looking at the screen but looking away from the screen as if facing the audience. Rehearsing this way forces you to remember what is on the projection screen without having to depend on it. Each time you click, you must know WITHOUT LOOKING what will be on the screen at that time. If you constantly look at the screen, you will become dependent on it , and your transitions from one slide to another will be the unpolished “And here”,  ”Next”, “On this slide”, “so, moving on…”, “And now”.

4) Tomi has rehearsed his presentation six times, from start to finish. He wishes he could rehearse a few more times but he has no more time. He is now convinced that whatever happens, he could not possibly do a better job. He hopes the Q&A won’t be too tough because that’s one thing, unfortunately, one cannot rehearse!

Similarly, you may think this is also ideal.  But actually, you can deliver an even better presentation by rehearsing some parts of your presentation more than others, like singers do. It is not necessary to rehearse the middle of your presentation as often as a) its beginning, b) its end, and c) the places when you transition from one slide to the next. Furthermore, a Q&A requires rehearsal, just as much as the presentation requires it. For that you need a mock audience to come up with unpredictable questions. As to the predictable questions, you need only look at each slide and ask yourself, what could they possibly ask me based on what they see here. Check everything: the sources of the data or of the visual (if it is not yours), the graphs, their axis, the boundary values, etc.

5) Kim is as ready as can be: many rehearsals, aloud, standing up and facing a mirror, perfect mastery of the presentation remote, perfect knowledge of which slide comes next even before it appears on the screen, perfect transitions. And all this without having to bother anyone!

You should bother more than one person and conduct at least one or two mock rehearsals in front of a small audience of people who are not familiar with the topic of your talk. That way, you can practice your warming smile without having to fake one. But more importantly, you can receive the feedback regarding the parts that people did not understand, and the parts that felt too long – AND modify your speech or/and your slides based on the feedback. Remember to also include a Q&A as part of the rehearsal.
