1 IAP Lecture Part 1. Animation in PowerPoint Part 2. Some features in Excel by Jim Orlin The slides are available on my website: web.mit.edu/jorlin/www/talks.html PowerPoint notes are available with many of the slides.

2 Introductions How familiar are you with PowerPoint and what do you hope to learn?

3 My Goal Have some fun Present some cool features Help people out Not a goal: focus on basic instruction in PowerPoint and Excel

4 Why I Love PowerPoint I have a poor memory Ability to focus attention of class Animation Ability to organize a lecture (and help with timing) Animation

5 But Some People Hate PowerPoint PowerPoint Is Evil Power Corrupts. PowerPoint Corrupts Absolutely. By Edward Tufte

6 Overview of Lecture First Half: PowerPoint –basic techniques –More advanced algorithm animation Second Half: Excel –cool effects for classroom presentations

7 How to Illustrate Concepts (or not) Difficulty in illustrating PowerPoint: there are tons of PowerPoint Effects. Some can be entertaining the first time. But they quickly lose the effectiveness. And they can be distracting and/or boring. And clip art doesn’t substitute for ideas. And reading what is on the slide can irritate audiences.

8 Algorithm Animation Powerpoint has lots of animation tools that are useful for illustrating concepts. Boxes can appear, and disappear. Colors and transitions can simulate movement. And one can use real movement. And pictures can help.

9 Using Custom Animation Boxes can appear, and disappear. Step 1. Select Custom Animation from the Slide Show Menu. Step 2. Select the item(s) to be animated. Step 3. Click on the add affect button Step 4. Add the effect.

10 Adding Animation to Each Slide Easily Select “Master” from the view menu. Select Slide Master Format title and other text styles Add custom animation Select Text Animation Group text if desired

11 On grouping text This animation effect is a wipe from left –it is grouped by second level paragraphs third level indents appear at the same time as second level ones. –fourth level appear at the same time as second level Next: Illustrating some more advanced techniques

12 What is the maximum number of diamonds that can be packed on a Chinese checkerboard? Each diamond covers 4 dots. class exercise: how many can you pack?

13 Here is a best possible 27 diamonds.

14 Computing an upper bound An upper bound: total weight such that for each diamond d, w(d) ≥ 1. Assign each circle (or node) a “weight.” The weight of a diamond d is w(d) = the sum of its node weights. Assigning ¼ to each circle gives a total weight of Can you do better?

15 Here are 27 diamonds What is the weight of the circles covered by diamonds?

16 Node Weight 1 1/2 1/3 1/6 0 Each diamond has weight at least The number of diamonds is at most 27.

17 A technique for animation creation 1.Select diamonds in the order that you want them to appear. 2.Animate them 3.Select the animated elements 4.Select “start after previous” or “start on click”

18 Carrying out movement 1.Select the item. 2.Add a movement effect with custom animation

19 Illustrating matrix operations. Adding a row of a matrix to another row Add row 1 to row 2. Have the answer appear by wiping down at medium speed. Or speed it up, as in adding row 1 to row

20 Illustrating Binary Search I am thinking of a number x between 1 and 64. You have 6 guesses. If you guess y, I will tell you if x  y or x > y

21 A cool macro for hiding things or possibly making them appear Put back boxes 789
