Physics 131

Schedule -- Redish

You can find an overview of the text readings for this class (plus readings I am not assigning) at: Working Content I

Notes:

  • This schedule is tentative and subject to change.
  • Reading Assignments are online; reading questions in WebAssign are due 11 PM the evening before the lecture.
    WebAssign Assignments are due Friday at 5PM. The paper homework is due AT THE BEGINNING OF the last class of the week.
  • Attend recitation and lab during the first week of class to do our survey, download the software for the labs, and meet the prof.
  • The content column links to slides from the PowerPoint presentation used in class. They will be posted after the class takes place.
    Note that these slides only represent a skeleton of the presentation and do not include solutions to problems and questions posed, derivations, or representations of class discussions. If you miss a class, these notes do not suffice to fill you in on what happened! Be sure to check with someone who actually attended. The files are Adobe PDF files.
