2. Advice for Giving Memorable TalkNever prepare your talk Spontaneous is betterYou can always read of your slidesBetter to spend time doing more researchDon’t worry about questions you might get: You are smart, you can handle them

3. Advice for Giving Memorable TalkNever prepare your talk Spontaneous is betterYou can always read of your slidesBetter to spend time doing more researchDon’t worry about questions you might get: You are smart, you can handle themCram all information from your research into your talk It’s an educated audience and they can keep upThey are smart: they will understand the detailsDon’t waste time explaining the basicsThat would insult your audience & waste timeThey will know what you are doing and why

4. Advice for Giving Memorable TalkAlways go over your allotted time Shows that you have done a lot of workIf you’re not last, your work is more important than those following youEveryone wants to know all the details of what you didGoing over time saves you from potential questionsBreaks are added into schedule to accommodate talk over runs

11. How to startShow title slide first (include name, affiliation & title)Then show something attention grabbing (e.g., photos of ice crystals in clouds)Explain what you will talk about (e.g., use of observed ice crystals to calculate cloud radiative properties)Give an outline of your talk

15. Microphysics: The Effect!On Oct. 13, 1947, the US military dropped 80 kg of dry ice into a hurricane over the Atlantic OceanShortly thereafter, the hurricane changed course and traveled inland, where it did extensive damageIrving Langmuir later stated that there was a 99% probability that the change in course was a result of the cloud seedingMicrophysics: The effect!

16. 16DAS, 9/3/04McFarquhar Well maybe microphysics does not matter quite that much ….

18. What to presentInformation overloadLimit yourself (think of yourself listening to others: how much can you absorb?)SelectionAsk if it is essential, otherwise toss it out!Know the point you are going to make for each slideSummarizeTell them what you are going to tell themTell themTell them what you told them3 important points to the talkNot 10!
