How to prepare for a talk: practice • • •
Decide if you should do it, and if so, make a commitment Consider carefully the investment of your audience Think about what you can convey in a talk more effectively than in a publication • Who you are and how they should perceive you is a big part of this!
•
• •
Know who your audience is and what they expect to receive. Why did they invite you or accept your proposal? Know how your talk fits into the larger program. This is true for seminars and colloquia too! Know where your talk fits in the day. Are they about to leave for lunch?
Think constantly about what makes a good talk. IMITATE

Practicing your talk: run throughs • •
•
For early talks, especially important ones, practice all you can stand Read out-loud, alone, the text you have prepared; get the difficult sentences and arguments down cold Consider taped practice sessions
• • •
Arrange practice sessions with live humans, ideally reflecting your real audience Ask people to help you on all aspects of the talk Test your graphics on people, and on yourself in the real environment
Even a talk you have given before need practice if it is to be excellent!

Practicing your talk: speaking style • • • •

Volume, tone, pace are all important Work hard to eliminate verbal ticks Consider carefully the use of colloquialisms or catchphrases A good joke is wonderful, but real care is needed too
• Speaking style is much more than voice • Your body: where will you stand • Gesture: can you avoid stiffness • Technology: how will you use laser pointers etc. • Other physical objects? This is unusual and can be very effective

It’s your job, like it or not Make everything works, don’t take risks unless you’re completely in your comfort zone Be prepared to punt on anything that doesn’t work

Data graphics •Especially important and too often ignored •The graphics you want for your talk are probably not those you put in your Nature paper •Every graphic should show just what you want it to, without forests of trivia •Color can be powerful, but remember the color-blind! •Consider the advice of datagraphics experts: Edward Tufte

Basic, essential advice •Data graphics should • Show the data • Focus the viewer’s attention on the substance • Avoid distortion • Present many numbers concisely • Make large datasets coherent
02/11/2009
• Enable appropriate comparisons • Reveal structure at various levels, and in various spaces •You should pursue excellence in all your graphics, published and for talks

Some principles •Clarity •Precision: telling the truth •Efficiency •Should give the viewer many ideas in a short time with the least ink in the smallest space •Multivariate graphics always convey more
02/11/2009
•In a presentation, focus on a few graphics which convey central information •Think about how long to spend on them •Think about pacing and not allowing them to grow stale •Graphics are memorable, think about revisiting them

Some Tufte basics •Maximize the data to ink ratio • Show the data • Erase non-data ink • Erase redundant data-ink • Revise and edit! •Examples follow •Forgo chartjunk • Moire vibration • The grid • The duck

Handling questions •Very important, active part of the presentation •Encourage short interruptions during the talk •Consider seeding… •Encourage questions at the end “What questions do you have” •Always repeat or restate
•Respond directly and as simply as possible •Don’t bluff •Never argue, you are in charge •If you already gave the answer in your talk, answer anyway •Deflect a repeated or irrelevant question •Prevent filibusters
Practice this too: insist that your listeners ask you questions in practice
