• Complete and thorough understanding of the material.– Even if you are teaching.
• To show how smart you are.– from Liang’s slides

Presenting a Talk
• “You walk in, plant yourself squarely on both feet, look the other fella in the eye and tell the truth.” – James Cagney
10
Presenting a Talk
• You will be nervous
• You will feel more nerves than you show.
11
Presenting a Talk
• Your experience of time is different than your audience.
• 20 minutes will feel like a blink.
• 1 minute can feel like an hour.
12
How much material?
• Maximum 1 slide per minute.
RULE OF THUMB
13
How much material?
• Have extra slides ready for questions.
14
Presenting a Talk
• Know what your next slide is.
15
Presenting a Talk
• Intonation Matters.
16
Presenting a Talk
• Be on time.
• “should I go on?”– The answer is NO.– but no one will say it. (Thanks Liang)
17
Be ready for questions
• Be gracious
• Be prepared
• Do NOT be afraid to say “I don’t know”– Being wrong will make you look worse.
18
Use of humor
• Tell jokes.– If you are funny.– Not too many.– They must be topical.
• Liang says 3– One at the start to engage the audience– One in the middle to bring them back– One at the end to leave them happy
19
What goes on a slide?
• Structure for you and your audience• Text Notes
• Visual Aids
• Data
20
Notes for yourself
• Avoid the easy practice of writing down exactly what you want to say.
• This will lead to a boring talk.• Your audience will read along with you, or sometimes
ahead of you.• They will not listen to what you are saying.• It is better to give yourself a couple of high level notes
that remind you and your audience where you are.• This is enough. • If it is not enough, you are not prepared.• Also, slides like this are visual overload on your
audience.• It looks like a big block of text.
21
Impression is not a lack of Detail
• Be specific about the contribution.
• Even if people won’t completely get it by the time the talk is over.
• Don’t be vague or overly broad.
What did you do and Why do I care?
22
Visual Aids
• Flow charts.
• Examples.
• Animations.– sparingly

• Go to more talks– (Even though you don’t know about the
topic)
• Recognize what you like about good talks– and steal it!
