Courses

I teach a range of courses offered in the Physics and Astronomy Department. These include Phys 201 – Introductory Physics I, a beginners course on classical mechanics, and Phys 626 – Introduction to Atomic, Molecular and Optical Physics, a graduate level course on atomic and molecular systems along with related modern topics. More information on either can be found below. Undergraduate students who wish to sign up for research with me can do so in PHYS 468, these credits count as upper division PHYS credits toward graduation.

Syllabus

The physics of life in motion, in four topics … Section is open to all majors but will use applications in class relevant to biochemistry, chemistry, and medicine.

Course Information

Lectures PHYS 201 010 begin 8/29/2017 TR 9:30AM – 10:45AM
Special video lectures will be planned with an "All Questions" voluntary session in place of normal class. These will be included as the schedule and class vote allows: three to six this semester.

Homework The HW will use the Mastering Physics Online site for the course ID: BWALK2017
Final HW grade on SAKAI two weeks after due date. Grade entered by discussion TA.

Laboratory Graded by laboratory TA. Laboratory manuals will be available on Sakai. Labs will be done by groups of two students.

Group lab reports will be submitted within two days of the lab experiment. Labs are limited to 5 pages maximum (10 pt font minimum, single spaced minimum). Labs are submitted in the format decided by the laboratory TA. For 5% EXTRA CREDIT on the laboratory grade, you may submit 8 of the 10 labs in the required 5 page format as a PDF to SAKAI online electronically under ASSIGNMENTS.

The final grade is in SAKAI one week after due. Do not skip labs since each lab is worth about the difference between grade assignments (e.g. C to a C-). The total Lab Grade counts for 15% of the total course grade. Lab grades cannot be transferred from a previous attempt at this course. A detailed grading rubric will be returned for each lab when they are graded.

If plagiarism is discovered between groups or from online content, all individuals in the group(s) will be reported to student conduct. Grade inflation or favoritism between sections is not tolerated. The average laboratory grade is expected to be consistent with the overall course grade and between sections.

All students may drop (or miss) one lab. Make-up of more than one lab requires an official excused absence.

Lab Grading (Approximate Distribution with final grading rubric determined for each lab by the TA)
Title   Title of the lab.
Purpose ~2 points Mention the specific purpose(s) of doing the lab.
Procedure ~6 points Describe how the lab is done. Explain the theory behind the lab and relevant formulas.
Result and Discussion ~9 points The most important section. Include measurements, error graphs, and you must discuss the results. Label with appropriate physical quantities, SI units, scale, slope, legends, etc. Sample calculations can be included with appropriate equations and measurements.
Conclusion ~3 points Show ability to conclude the few physical
concepts from measured values. Mention what new theory (calculation) or experimental skills gained.

Discussion and Quizzes

Begin Sept 5, 2017. Required, Quizzes will be given during the discussion after HW is due. The one question quiz is taken from completed HW. Graded by the Discussion Grader TA out of 3 points. Final grade in SAKAI one week after quiz given, entered by Discussion Grader TA.


Tests

Graded by Barry Walker. Mid-Terms will have 20 points maximum for a 100%. The mid-terms are in the evening. Final is cumulative over all topics.
