============================================================================
 Policies regarding homeworks/problem sets, PLEASE READ THEM:

 There will be about 8 problem sets during the semester (1 every 1.5 weeks,
 more or less).   The problem set answers have to be typed, and uploaded in
 pdf format, to the canvas site.  A LaTeX template that you can use to type
 the answers is posted in the Problem Sets page of this website.

 A) COLLABORATION:  It is OK to exchange information with other students, in
    the sense of hints,  general ideas,  pitfalls to avoid and so on;  i.e.:
    "within reason" ---- "let me see/copy" your answer is not within reason.
    But, the final answer must be written 100% alone,  with understanding of
    every dot that goes in there.

    WARNING: ****************************************************************
    * You are 100% responsible for any answer you supply in a problem set, or
    * (for that matter) in the term paper.
    * I can call you any time to explain your answer.   If I am not convinced
    * that you understand what you wrote, you will loose credit,    up to and
    * including loosing credit for the whole problem set, depending on degree
    * of lack of understanding.     In the case of the term paper, this could
    * make it "not-acceptable".
    *************************************************************************

 B) WARNING-WARNING-WARNING-WARNING-WARNING--CLARITY:
    ************************************************************************
    Your answers must be presented in a way that is easy to read. Type them
    with a reasonable font size (e,g.: 12 point).    Use English to explain
    your arguments.  If you include figures: label the axes;  have a title;
    and use captions. Material that fails to be readable may end up with NO
    credit given.  The TA/Grader should not have to "guess" what you intend
    to say, it should be there for them to see.

    As for the level of rigor:  "Math. proof level" is not expected.    The
    same  level as in the lectures, book, or notes ("reasonable scientist")
    is the expectation.
    ************************************************************************

 C) Note that only the  "quiz-problems"  will be graded in each problem set.
    Since these will not be announced, you should do all the problems --- if
    you happen to miss them in your answer,  you will get zero credit,  even
    if you did the others. Answers will be provided for all the problems.

 D) Any "suggested reading", "suggested problems" and any other "suggested"
    are for you alone to do or not do. Thus: DO NOT hand in these problems!

 E) About COMPUTER ASSIGNMENTS (if any):

    a) Use any language or computer you like. I recommend MatLab. I will
       provide some scripts that should be useful to do the problem sets.
       Use them!

    b) Include BRIEF explanations of how the problem was solved.  I want
       to know WHAT are the IDEAS and methods that you used.

    c) Results must be CONDENSED to some COMPREHENSIBLE and CONCISE form:
       * Use plots, tables or graphs. Do not show "raw" numerical output.
       * Make sure one does not have to hunt for the answers all over the
         place.  They must be EASY to find and identify.  Put them at the 
         beginning, for example, and then justify them.

    e) Include a printout of your program appended (AT THE END) --- if there
       is one.  If you used "canned" software, state which one, and SPELL
       the numerical parameters and other such data used  --- these things
       usually give you a choice of time step, numerical method, etc. I do
       not want to see such things used as "black boxes" with default
       parameters. I want you to think, and know, what you are doing.

    f) Look at your output and make very sure it makes sense! That a program
       "runs" does not mean it does so as intended.  For example, if you are
       using too large a time step, you will still get some output ... which
       can easily be nonsense!
