	Final Exam	25%

NOTE: You must receive a passing grade in each part (Lecture and Lab) separately in order to pass the course as a whole. If you fail either part, regardless of your grade in the other part you will fail the course!!

THERE IS NO EXTRA CREDIT!! Doing poorly for a portion of the semester will not be corrected by any extra projects. Please do not assume you can replace poor work under any circumstances with any “additional assignments”!!

In the event that the University cancels classes on the day of a quiz or exam, be prepared to take the quiz or exam at the next available class period. Any homework or other assignment due to be turned in on the canceled day, should be turned in at the same time listed on the next day the university is open, whether or not the class is normally held on that day.

Students are expected to be proactive in dealing with issues that require missing class. The professor would prefer that students, who are ill, not come to class and potentially spread their illness to other members of the class. The professor understands that on occasion unforeseen legitimate circumstances will arise such as family deaths or other family emergencies that requires a student miss class. In these cases however, the student should expend every possible effort to keep the professor apprised of the situation (usually by email). Let the professor know when you expect to be back in class. It is unacceptable to wait until the next time you happen to be in class to let the professor know what is going on. If you choose to wait until you are in class again, the professor is within his rights to deny the making up of any missed work or even accepting previously completed work that was not turned in on time. Finally understand that the professor needs to be fair to all members of the class and may ask some questions about the situation. He might require appropriate documentation from additional sources such as a doctor or the dean of students. Students are expected to provide reasonable information.

Because of the amount of work done in this class, falling behind will cause a severe hardship to a student. Catching up is extremely difficult. In order to prevent this from occurring, homework and labs must be turned in on time. Any assignment not turned in on time may incur a 10% per day late penalty. Moreover, no work will be accepted more than one week late. Note: Exams are not included in this policy (see below). If you have a specific problem that requires your work to be turned in late, you should discuss the situation with the instructor.

A good working knowledge of differential and integral calculus is assumed for all participants in the course. Additional math techniques will be taught to the students as needed. Please feel free to ask for additional help if this additional math is causing problems. This is not a math course. The aim is to learn about physics; however, physics is a mathematical subject. When having difficulty with material, try to decide if it is the physics or the mathematics that you are having difficulty with.

There will be two exams: a midterm and a final in this class. All exams are going to be take-home exams. There will be no extension on the due date of these exams. Failure to turn in the exams by 5:00 PM on the date specified will result in a zero for the exam. You are free to use any printed reference material you may find. Nevertheless, you are not allowed to discuss the exams in any manner, even hypothetical, with any persons other than the professor. Of course, you may bitch and complain about how hard or how easy the exam is, but nothing specific please.

Tentatively, the midterm will be handed out on Monday March 11, 2019 and will be due at 5:00 PM on Monday March 18, 2019. The final will be handed out on Wednesday April 24, 2019 and will be due on Wednesday May 1, 2019 at 5:00 PM.

Homework will be assigned periodically. It will be collected and graded. It will be due at 5:00 PM the day of the date announced. All homework problems are to have the problem written out in full (including any diagrams) at the top of the page. You may not leave out words or abbreviate any words from the book. The ONLY exception is you may leave out circuit figure references since you will draw the circuits for each problem. For example instead of writing “The circuit shown in figure P. 7.4-8 is…” you may write “The circuit shown …” or “The circuit below…” Otherwise, all other words must be written out. Failure to do this will result in a loss of points.

You are to use only one side of a sheet of paper while solving the problem. Start each problem on a NEW sheet of paper. All homework is to be done on standard size paper. Homework should be assembled with care to ensure that all pages are in correct order. Problems should proceed in an increasing numerical order with any Extra problems assigned from outside the textbook being placed after the assigned textbook problems.

Do not staple papers!! Please use paper clips. The Professor will place boxes of paper clips in the classroom for your use. Homework, as well as exams and labs, should be free of debris: coffee stains, food particles, eraser pieces, ragged edges, etc. Please make the pages as neat as possible.

Papers, which the professor cannot read for any reason (legibility, size of your writing, contrast between writing and paper, etc.) are just wrong, and all points will be lost. Additionally, pages out of order, upside down, backwards, etc. may also result in a loss of points. A wise student would do a final check to ensure that all problems are present, complete, legible and in proper order before turning them in. Homework is YOUR opportunity to show the professor that you understand the material and can produce a proper solution. The numerical answer is not the final criteria. All problems, which require numerical answers must be, have a value not an equation. Moreover, all numerical answers (unless they are pure numbers), must have an appropriate set of units. No units when needed, No Credit for the problem!!!

It is not the responsibility of the professor to take extreme measures to ascertain whether the student has provided correct and proper information. The professor is willing to work with students on this, but if work is not legible, whether due to poor penmanship, poor printouts, staining of papers, insufficient ink or lead on the page, or any other reason why a paper cannot be read is solely the student’s responsibility. Moreover, students are required to comply with all instructions provided by the professor. Students may ask questions, but failure to follow instructions can result in the loss of points up to and including all points for the assignment.

Please understand that you are convincing the professor that you actually understand the material. It is not for you to do the least amount of work possible. The phrase “…By Inspection…” or any other similar meanings “...it is obvious...” are not acceptable. Even the concept of 2+2 = 4 can be explained. Again, the goal is not for you to minimize your efforts, but to maximize your demonstration of understanding!!

Please be aware the professor knows many of the problems in the textbook provide an answer. You may not just write down the answer even if you claim you can do the problem by inspection. In fact you may never use the phrase “By Inspection”! You are to provide some reasonable and correct justification for all problem solutions. Solutions are just that, solutions. They require occasional words to explain why the equations being used are the right ones, etc. Do not just provide a string of equations and algebra and produce a final answer. Show a thought process! Finally, occasionally the book provided answer is not the answer the professor believes is correct. The professor’s answer is the correct one by definition.

These are not suggestions! They are requirements. Homework not done by these specifications is subject to loss of points including all points at the professor’s discretion. Failure to use these specifications on subsequent homework assignments will see an increase in points deducted.

An Example Homework problem with proper formatting and presentation is provided at the end of this syllabus for your reference.

You are encouraged to work with others in the class on the homework. However, write-ups of the problem solutions should not be “Xerox” copies of other students’ solutions. You are encouraged to see the professor for help as well. Recall the “15 minute” rule. The professor is willing to discuss homework answers prior to homework submission; though he is not willing to verify answers for exams prior to submission.

MATLAB RULE: All Homework Problems, Exam Problems and Lab Exercises, which ask for sketches or plots, are to be done in MATLAB only. NO HAND DRAWN PLOTS EVER!!! No use of Excel! All such MATLAB plots are to have your name, date, proper axis labels, especially including appropriate units, and the scales should be such that as much as possible a single page is filled by the plot. All MATLAB work must include the m-file that created the plot or solved the problem. The m-file should have cleaned up text from the command window showing the answers in a comment section at the end of the m-file. By cleaned up it is meant that extra spaces, duplicate results, error messages, etc. should have been removed. Your professor will explain this to you.

Proper axis labels would include either {Force, F, (N)} or {Ln(Force), ln(F), (ln(N))}

Proper titles would include a description for the plot, and your name and the date on a second line. For example: Plot of Power Dissipated vs. Load Resistance

D. W. Donovan – Jan 7, 2011

In addition to providing printed MATLAB work, for each assignment (homework and exam), you are required to send an email to the professor either identifying that you did not use MATLAB or you attached a zip file containing all MATLAB files produced to solve the assignment. This email is also due at 5 PM. Failure to send the email on time may result in loss of points. MATLAB work must be separated so that each MATLAB file is used to solve one problem in the assignment. Do not create one

large MATLAB file that solves everything! Each use of MATLAB must have code to associate with it. Failure to provide the printed MATLAB code with the problem it belongs to may result in loss of points.

You may use an integral table, but you may not use MAPLE, MATLAB or any other Symbolic Manipulator Program to do the integrals for you. Please show the Standard Integral form in your work.

For Example:

The Link below will download a zip file that contains the printer installer for the printer in West Science 2506. Unzip the files into a directory on your desktop. Go in and right click on the file “kickoff.cmd” and select “run as administrator” The printer driver will be installed so you can print out work for this course to turn in. If you need help with this, see the professor.

Labs will be graded upon filling out a worksheet and performing the required analysis. Normally, there will not be any formal lab report write-ups; however, there may be one or more labs that the instructor will ask to have written up formally. The lab materials are typically due at the start of the next lab period unless the professor has indicated that more than one week will be devoted to the lab exercise. Labs will be done with partners, who will all be present in the lab room until the either the work has been completed or the lab time is over. Please refrain from coming to lab late. Some of the experiments have the potential to destroy lab equipment. Please do not apply power to a project until you have fully checked it over. Do not wire a project with power being on. Be careful with Electricity, even the small doses we use can cause problems!!!

Attendance at all labs is mandatory. Make-ups for labs will only be provided for at the discretion of the professor. This will occur only for reasonable excuses. Desire to go home for the weekend or to go hunting are not considered reasonable excuses. Informing the professor BEFORE an absence is more likely to result in a make-up than informing the professor after the absence. A missed lab is a zero for that experiment and all associated work!! Labs begin in the FIRST WEEK OF CLASSES!!!

Please wear shoes that completely cover your feet in lab. Open toed shoes and sandals will not be permitted. If you wear such shoes, you will be asked to leave lab to change. This is a safety issue and this will not be ignored! Bare feet and/or just socks are not allowed in the lab!!

Food of any kind (including snack food) is not allowed in the lab or classroom. Please do not bring it in. Drinks will be permitted as long as care is taken not to have spills occur and the drinks do not result in loud noises. If excessive spillage or noise occurs, drinks may be restricted as well.

The professor will make every effort to respond to all email (ddonovan@nmu.edu ) questions received by 5 PM Monday through Friday, with a response by 10 PM Monday through Friday. Students are

expected to regularly check their NMU issued email accounts for any messages the professor may send out to the class as a whole or to an individual in the class. Moreover, when students ask the professor a question requiring an answer, it is expected for students to check their email in an equally timely fashion and to confirm the receipt of the answer, and if necessary provide any answers to questions the professor may have posed about the situation. The professor reserves the right to cancel any deals proposed in email correspondence if the student fails to confirm the deal with a final email.

Homework, exam solutions, and other material will be posted on the World Wide Web at my webpage, which is located at: http://physics.nmu.edu/~ddonovan/classes.html The professor will also make every effort to have all handouts available on his web site for download if you should lose your copy.

Please Note: I do not use Moodle or NMU EduCat!

The professor is always willing to discuss the grading of materials. Students should review their returned work promptly. If they believe an error in grading has been made, they should arrange to meet with the professor as soon as possible after the work is returned. Grades will not generally be changed after the student has had the work in their possession for more than one week. The work should not have been further marked upon or changed in any way by the student if they wish to discuss a graded item. The professor is happy to discuss what is correct or not correct about an item with a student, but there is no discussion on the number of points awarded or deducted by the professor.

The professor makes every effort to return collected work in a timely fashion. There may arise situations in which homework assignments and/or laboratory exercises may not be returned before the next homework or laboratory exercise is due. Students are reminded that in spite of the fact that you may not have gotten your previous work back and seen that you failed to follow directions, this does not mean you cannot be held to following the directions on the subsequent assignments. The handouts and their directions remain enforceable unless the professor indicates otherwise. As always, if you are unclear on directions, you should ask the professor for clarification.

The professor will retain in his possession all final exams for a period of one year. Students may arrange to see the work during this year. The professor is not going to provide specific grades over the phone or on email at any time prior to final grades being displayed on MYNMU (this usually occurs on Thursday after graduation).

If you have any questions or problems talk to the professor. If you need any special arrangements, they should be arranged prior to the problem, unless this is completely impossible (a rare occurrence!)

Students in this class are expected to conform to a code of academic honesty. While it is encouraged for students to work together, there are situations where work is expected to be the student’s whose name appears on the work. Exams are obvious examples of where cheating will not be tolerated. Identical homework solutions are another example of cheating. Using the same code and

documentation (even if you change your name and modify some words), is also considered cheating. For example, using the same MATLAB m-files (unless given permission by the instructor) in lab or for homework to produce two copies of plots or problem solutions (even if you change your name), is also considered cheating. Students are expected to learn how to create their own files. In lab work, it will often be the case that both partners will have identical work. However, both partners are to turn in lab sheets, and both partners are expected to participate equally in completing the lab tasks. It is not acceptable for one partner to do all the work, while the other merely watches and writes. Both partners are expected to understand the lab exercises. If you have questions on what is considered appropriate, ask your professor.

Please be sure any cell phones or pagers or other devices do not produce sounds during lectures.

Please do not engage in conversations at all during lectures and at times when the professor is lecturing during a lab exercise. At times when the professor is not lecturing during a lab exercise, you may have conversations provided they are not offensive or distracting to other members of the class.
