Professor Walker teaches 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 Professor Walker can do so in PHYS 468, these credits count as upper division PHYS credits toward graduation.

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. |
