Presentation lecture w3_2015_v2
- 1. How To Talk Good Robert Williamson Ecology & Evolutionary Biology What goes in a talk? What are common problems with talks? What should go on a slide? How can I make my slides clearer?
- 3. Section1–Whatgoesinatalk? What makes a talk good? (Or not so good?)
- 7. Section2–Whatarecommonproblemswithtalks? What are slides for? What are they NOT for?
- 9. Section2–Whatarecommonproblemswithtalks? “PowerPoint Is Evil. Power Corrupts. PowerPoint Corrupts Absolutely.” – Edward Tufte “PowerPoint may now and then benefit the bottom 10% of all presenters. PP forces the really inept to have points, some points, any points.” – Edward Tufte
- 10. Review of Test Data Indicates Conservatism for Tile Penetration •The existing SOFI on tile test data used to create Crater was reviewed along with STS-87 Southwest Research data - Crater overpredicted penetration of tile coating significantly Initial penetration to described by normal velocity • Varies with volume/mass of projectile (e.g., 100ft/sec for 3cu. In) Significant energy is required for the softer SOFI particle to penetrate the relatively hard tile coating • Test results do show that it is possible at sufficient mass and velocity Conversely, once tile is penetrated SOFI can cause significant damage • Minor variations in total energy (above penetration level) can cause significant tile damage - Flight condition is significantly outside of test database Volume of ramp is 1920cu in vs 3 cu in for test
- 11. The Cognitive Style of PowerPoint. E. Tufte
- 14. Section2–Whatarecommonproblemswithtalks? What are some ways that slides are often misused?
- 15. SENSI NG CI RCUI T ARCH I TECH TURE • Parallel • Series
- 16. Life History Traits Life history traits - Physiological and morphological characteristics • Variation in characteristics for organisms can alter fitness • Phenology (i.e. timing of expression) • Effort (e.g. fecundity) • Allocation of Energy Trade-offs between traits Modified by environment • How does maternal competition influence life history traits?
- 19. In 15 minutes or less... Motivation & aims;! Tools & methods;! Preliminary results;! Future directions & implications.
- 20. Section2–Whatarecommonproblemswithtalks? Outline I will give a talk on some stuff
- 23. !! 5!
- 25. Section3–Whatshouldgoonaslide? How can we use slides better?
- 26. Write a sentence headline that states the main assertion of the slide In the body of the slide, support the headline assertion with visual evidence, using text only when necessary Modified from Garner. Intl J Eng. 2013
