Robert Geroch suggestions applied to the subtitle of your talk

You will find Dr Geroch’s “suggestions for giving talks”, online. The paper is stored on arXiv.org, the open access site managed by Cornell University. I have read this excellent paper many times and recommend you do likewise. My intent is not to ask you to change the title of your  talk. As soon as your conference abstract or paper has been accepted, this title is pretty much carved in stone. It will bring the audience to you – and, justifiably, the audience expects the title of your talk to be the same as that featured in the conference program. A dull demagnetized title or a title replete with repealing highly technical keywords cannot be repaired post publication. Expect experts or sleepers to your talk. If, on the other hand, your title has centripetal appeal, if it is a centre of interest to experts and non experts alike, you can enhance its understanding and appeal, right there and then, on the title slide, by adding a subtitle that really makes your focus clear. A good subtitle is easily understood by ALL.

Dr Geroch writes

“Thus, for an audience of relativists, “Linearized Fields in a Kerr Background Metric” sounds technical, “Perturbations of the Kerr Solution” sounds dull, and “Black Holes are Stable” sounds good.”

Questions are often frowned upon by editors when used as titles, but they are always acceptable as subtitles on a title slide. “Can a mesocellular siliceous foam firmly entrap a catalytic enzyme?”, “what if we could actually firmly entrap a catalytic enzyme in a mesocellular siliceous foam?”  Notice that the expectations set by these two questions are different. The first question focuses the audience on the couple of words “firmly entrap” – a method -, while the second question prepares the audience to a presentation of the outcomes of firm catalytic enzyme entrapment.

Use the subtitle to guide audience expectations, but do not let that be an excuse to skip the presentation of the keywords that brought the audience to your talk in the first place.
