Course Objectives
The aim of this course is to teach you concepts and understanding of the physical world. Doing problem solving is an important part of this course, and your grade will depend on your ability to understand concepts and to solve problems. An understanding of the material is crucial to your ability in problem solving, as is the acquisition of a set of skills about problem solving. The lectures are oriented towards helping you understand the concepts and how to solve problems. We will perform many demonstrations and solve many examples and problems in class and during the discussion section. Understanding the material is the best long-term way for you to be able to solve the problems that an engineer faces. Read each assignment before the lecture and again as soon as possible after the lecture. Attending the lectures and seeing demonstrations is an important way for you to understand the material. Doing the warmup questions and assigned homework problems as well as attending the problem sessions is an important way to acquire problem-solving skills. You must be enrolled in the problem session in addition to the lecture. Quizzes will be given during the problem session. Note that a significant part of your grade depends on these quizzes, so you must attend the problem sessions.

WarmUp Questions
Before each lecture students will be assigned typically three questions on the day's lecture for which they will answer no later than 8 a.m. on the day of the lecture. The questions will be presented on WebAssign, and the students will answer on WebAssign. The purpose of this activity is twofold: 1) to encourage the student to prepare for the day's lecture by reading and studying the textbook and 2) to let Professor Thornton understand on which topics the students need the most instruction. Typically two of the questions will be essay for which the student will type in the answer. Professor Thornton will read these responses each day before lecture in order to gauge what are the most important topics that need to be covered that day. He will be able to judge this by the students' answers. A grade of 0 through 3 will be given for each assignment. A grade of 0 indicates the student either made no attempt to answer the day's questions or the attempt was not sincere. A student who sincerely tries to answer the questions and apparently has prepared for the day should receive at least a 1.5. A student who apparently guesses or who seemingly is not well prepared might receive a 1or less. Individual responses will not be given to the student, but the daily grades will be posted. These questions will only be given on lecture days, not on problem session days.

Homework Assignments
Students will be expected to work and study outside the classroom. Weekly homework assignments will be posted here on the website. The problems will be available on WebAssign, and the responses will be given on WebAssign.

Tutoring
The E School is providing a tutoring session for PHYS 142R and 241E on Wednesday evenings from 6 - 8 pm in THN D222.

Remarks

  1. Exams are separately scheduled in the evening, not during regular class time.
  2. No makeup exams will be given. Missed exams receive a grade of zero unless an excuse for missing the exam is given to and accepted by me before the exam.
  3. Each week there will be a graded quiz that contributes to your final grade. Missed quizzes receive a grade of zero unless an excuse for missing the quiz is given to and accepted by me or the teaching assistant before the quiz.
  4. Homework is due when posted on WebAssign. No extra credit or makeup assignments will be given. Keep up!
  5. Regrading: I will correct arithmetic grading errors on exams and quizzes, and I will consider differences of opinion between answers submitted and the exam solutions. Regrade requests must be submitted in writing within 7 days after the exam is returned, explaining how much credit you think you deserve and why you think you deserve it.
  6. Collaboration on homework problems: I encourage you to discuss homework problems with each other and to work out together methods of solution. However, the homework answer that you submit to WebAssign must be your own that you calculate. It is an honor violation for you to copy another person's solution. You are also encouraged to discuss the Warmup Questions.
  7. Attendance policy: Attendance is not taken, but you are responsible for all assigned material, whether it is presented in lecture or not. You are also responsible for knowing the problem assignments and for any announcements of changes in the schedule that may be made in lecture.

Homework Assignments. We are using WebAssign for the homework and warmup questions, and you must submit your answers on WebAssign. Because the numbers in the problems are randomized, you must log on to WebAssign with your login and password and obtain your personal assignment for the week. Please note each week how many submissions you are allowed. Your last submission is the one graded. Note that you must finish by the posted time on the due date. I can not accept late homework or warmups with WebAssign.

Course Rules and Regulations:

It is important for students to be aware of these rules and regulations which may change throughout the course. Changes will be announced in class, and all changes will be listed on the website. Students are responsible for keeping up with the Course Rules and Regulations as stated on the website.

Course Rules and Regulations

 In general, assignments and notices will be listed on the course webpage. This includes, but is not limited to, homework assignments, syllabus changes, course rules and regulations changes and additions, dates and times of any review sessions, and material to be covered on class exams.

  1. Illness (as an excuse) must always be established in writing.

    EXAMS:

  2. If you do not turn in an assignment (including homework) on time or miss an exam (including being late and for illness), you will receive a grade of zero, unless you have prearranged approval by Professor Thornton. Messages of any kind including, but not limited to, email, telephone message, oral messages of any kind, notes delivered by a third party, etc., are not acceptable by themselves without a response by Professor Thornton. Any oral approval given by Professor Thornton must be confirmed in writing.
  3. If you miss the beginning of an exam, you will still be expected to turn in the exam at the end of the regular class. Oversleeping is not an acceptable excuse. If you miss the exam, you will receive a grade of zero.
  4. There will be no rescheduling of exams except for instructor approved medical emergencies or official university travel. Leaving town for anything else including, but not limited to, vacations, family reunions, concerts, Nobel prize receptions, White House visits, athletic events for non-participants, etc., will not be an acceptable excuse for missing an exam or for not turning in homework. All rescheduled exams may, at the discretion of the instructor, be oral examinations.

    HOMEWORK:

  5. You may work together in doing homework, but you must work out the solution you submit to WebAssign.
