5/06  A copy of the solutions to Test 4 is now
      available at the Noble Library Copy Center.

4/29  In preparation for our test next week, my
      office hours on Wed 4/30 and Fri 5/2 in 
      PSF-462 (usually from 3:40 - 5:00) will be 
      extended.  I will be available until at least 
      7:00 PM to answer your questions about 
      Chapters 12, 14, and 16.

4/21  There is an misprint on the distributed HW 
      Schedule for lecture #23 on Apr 24.  The 
      problem listed as F12:3 should be F12:35.

4/17  A copy of the solutions to Test 3 is now
      available at the Noble Library Copy Center.

4/03  The online problem set for Chapter 11 was 
      originally posted with a typographical error.  
      The error was corrected on 4/01, so make sure 
      that you have the version with the correction.  
      The correction was to problem P78.  

3/14  A copy of the solutions to Test 2 is now
      available at the Noble Library Copy Center.

2/27  Next week I will be in Austin, Texas, attending
      the March meeting of the American Physical
      Society, which is particularly for solid-state 
      physicists.  This meeting usually occurs during
      spring break, but that is not the case this year.
      All classes will meet as usual.  Your lectures
      will be given by Dr. Carl Covatto.  During my
      office hours, PSF-462 is reserved as usual for
      you or your study group, but of course I will not
      be there to answer your questions.  If you need
      help, please see your TA's during their office 
      hours.  I will return on Sun 3/9.  Please see
      me during my office hours on Mon 3/10 if you have
      questions relating to our next test, which occurs
      on Tue 3/11.

2/20  A copy of the solutions to Test 1 is now
      available at the Noble Library Copy Center.

2/11  There is an error on the distributed HW Schedule 
      for lecture #8 on Feb 13.  Please drop problem
      P49 from the list of HW problems for that lecture,
      and add CH 6 problem 20.  Also note that the topic
      covered by problem S5: 46 from that day WILL be
      included as a possible topic for Test #1 on Tue
      2/18.

2/10  Comments on the neatness and organization of HW.

           It is to your advantage to make your HW as
      neat as possible.  If your TA can follow your
      logic clearly, then it is more likely that you
      will receive the proper credit for your work on
      the 10 point problems.

           It is also to your advantage to organize
      your HW as clearly and as neatly as possible.
      This increases the likelihood that your TA will
      find all of the one point problems and be able
      to determine that you have made a "good faith
      attempt to solve them."  Please do not simply
      copy down the right answer and then expect to
      receive credit for an attempt to solve any
      particular problem.

           Neatness and good organization is to your
      own advantage as well as a point of consideration
      for your TA and for your fellow students, whose
      papers are being graded at the same time as yours.
      Remember that your TA is grading as many as 100
      HW papers per week.

           Homework that is EXCESSIVELY sloppy and/or
      disorganized, to the point of being extremely
      difficult or impossible to grade, will not receive
      credit, at the disgression of your TA.  In such
      a case the TA will make a copy of your HW paper,
      in case of an appeal to the course instructor.

1/29  The old tests (from Summer 2002) are now available 
      in the Noble Library Copy Center.  They are available 
      with or without solutions.  The 'without solutions'
      version is useful for giving yourself a timed
      practice test.

1/23  The location of my TTH 11:15-12:15 office hours is 
      misprinted in the distributed syllabus.  The correct 
      location is PSF-430.  I apologize for any confusion
      this may have caused.
