  1. Set-2A Very Boring Lecture** Some Tools for Later ** Sorry about that

  2. HW Assignment Read the rest of chapter 1

  3. NOTE

  4. The Three Tools • Scientific Notation • Graphs • Converting Units Don’t be offended if you already know this stuff. Feel free to take a nap.

  5. An Atom ~0.0000000002 Meters 9 zeros after the decimal point !!

  6. Datsalottazeros! ~0.0000000002 Meters Dersgoddabeabedderway And there is! Scientific Notation is a way to get rid of most of those zeros.

  7. Do you remember? The Exponents Add!

  8. The Sequence • 20=1 • 21=2 • 22=4 • 23=8 • 24=16 • 25=32 • 1,2,4,8,16,32, ……. Interesting but would be better if we only had one finger on Each hand!

  9. Which is better for counting? 5 1

  10. This works for other “bases”

  11. Clicker: How Much Is • 16 • 43 • 128 • 32

  12. You use what you have … • 5 fingers on each hand. • 2 hands • Toes are inaccessible • 2 X 5 = 10 • Lets look at “base” 10

  13. “Base” 10

  14. Some of the numbers Nicer !

  15. A real number { Scientific Notation 6 Zeros

  16. What about decimals? ONE ONE

  17. So.. 4 places after The decimal point First non-zero digit

  18. Powers of 10 (meters)

  19. What’s it all about?? Powers of 10 http://www.youtube.com/watch?v=41gWUkVQ-9U PowerPoint Version also available.

  20. Does Scientific Notation have any use in music?? Indeed !

  21. The Path of Music

  22. The Path of Music

  23. TheEar brain “Loudness” increases with The AMPLITUDE of the Back and forth movement of the eardrum.

  24. More on Loudnesslater in the semester

  25. Let’s review graphs. • A Graph is a way of visually presenting data from a table. • It usually has two axes. These axes can be anything but in science it is often an x- and y- axis. • Sometimes a graph is three dimensional.

  26. An Important Graph DJIA ($) 1 box = 1 month time The Dow Jones Industrial Average (CNN-money 7-08

  27. Another Important Graph 10 years of data – a different view! 6 mos

  28. Last Topic in this SetUNIT CONVERSION • We need to convert days to seconds • How many seconds are there in 2 days? • What do we know? 1 day = 24 hours 1 hour = 60 minutes 1 minute = 60 seconds

  29. UNITY “Days”cancel; Trick: Keep multiplying by unity!

  30. So now you know ….if you didn’t know before. • Scientific Notation • Graphs • Unit Conversions Note: WebAssign HW
