2. Audience and Prerequisites

  • It is the goal of this course to make some of these profound ideas accessible to non-scientists with a minimum of mathematics.
  • The prerequisite is only high school algebra.
  • The class meets for one hour and fifteen minutes twice a week.
  • Discussion sessions for fifty minutes twice a week are optional.

3. Requirements

  • Attendance required - no more than 3 absences
  • Homework ~ every other week
  • Mid-term Exam (perhaps 2 mid-terms) and Final (multiple choice and problems)

3.1. Class Projects

The class will be divided into ~10 groups of 5 to 7 students each. Each group should have one student who is familiar with MS Excel. Each group will be assigned a data collecting and analyzing project that will continue through the semester.

3.1.1. Project choices

Some of these projects involve physical phenomena. Others are connected to human behavior. The data is available from news media &/or websites.

  • Stock market - Dow-Jones - Are there any patterns? (Movie "Pi")
  • Stock Market - Foreign (Japan, or Britain or other)
  • Oil prices - international & local (gas stations?)
  • Natural gas prices - international & local
  • TV Weather predictions and actual measurements - How good are 1 day & 2 day predictions of temperatures?
  • TV Weather predictions and actual measurements - How good are 3 day & 4 day predictions of temperatures?
  • Weather - predicted & actual precipitation
  • Solar Energy &/or UV amount - local or beyond?
  • Tides - time and height of high and low tide in our area - What is the pattern? Construct a model.
  • Earthquakes - regions and magnitudes (of 5.25 or more)

3.1.2. Presentations

  • Data will be entered on group spreadsheet daily or once a week by each group. Group will try various means of display. Attempts will be made to find systematic behavior of data. Once a week or so a copy of Excel file should be placed into instructor's Drop Box on website. Various displays will be posted on class website.
  • Near mid-semester a summary of results should be prepared by each group. Short presentation to class will be scheduled over remaining weeks for each group.

3.1.3. Organizing each group

  • At least one Excel savvy person enters data
  • Group writes an explanation of how data was selected
  • Use Communications for groups
    • Group Pages รข?? roster, discussions, collaborations, email
  • Drop Box to Prof. Goldstein every 1 or 2 weeks
    • Graphs and explanations - keep to minimum
  • Present to class - cycle through groups

4. Texts

  • Feyman, R.P. Six Easy Pieces
  • Hoffmann, B. The Strange Story of the Quantum
  • Frayn, M. Copenhagen
  • Notes and copies of articles will be handed out or posted
  • Several other texts will be on reserve:
    • Gamow, G. Mr. Tompkins in Paperback
    • Lightman, A. Great Ideas in Physics
    • Hewitt, P.G. Conceptual Physics
