Physics 132

Schedule -- Redish

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

Notes:

  • This schedule is tentative and subject to change. Reading Assignments are online; commentary in WebAssign is due 9 PM the evening before the lecture. Assignments are due Friday at 5PM.
  • Attend recitation during the first week of class to do our survey and meet the prof.
  • Recitations and labs begin on September 7th.
  • 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.
