TEXTBOOK: Modern Physics 2nd ed. by Randy Harris (Pearson/AddisonWesley)


PREQUISITES: PHY2061 or equivalent  and MAP2302

In this course students will be exposed to physics developed in the late 19th through the early 20th century including relativiry, quantum theory, and their applications to modern physics.  Land mark experiments that have led to the new ideas and understanding, and their theoretical developments will be discussed.  This course deals with the topics with an emphasis on the conceptual rather than rigorous mathematical understanding.  However, as in any physics courses, students should expect to perform quantitative analysis using calculus, geometry, and differential equations as well as qualitative estimations based on order of magnitude calculations and dimensional analysis. 

It is expected that students are comfortable with calculus including vector calculus,  differentiation, integration, and trigonometry. Students should also be able to solve ordinary differential equations.  It is also expected that students read textbook chapters thoroughly at least once preferably before the class and review lecture notes timely.  Students should work on HW problems diligently.  On average 4 - 6 hours per week of full attention on this course would be required.  Read THIS!


Math Prep Test     Students will have to review Essential Math in the first week and will be tested in class.  

Homework     HW will be assigned in this course and will be checked.  Students will be asked to discuss and solve selected HW problems during the classes after the HW due.  HW grade will be given based on this performance and the submitted work.   Selected HW problems will be tested in the exams. 

Colloquium (Bonus)    Attending physics colloquium regularly would expose you to the current topics in physics. Students will get credit up to 6 additional points for attending colloquia (Thursday 4 pm in #1002) if a report is submitted.  Each report (3 pts) should include less than 300 words summary of the talk with his/her own questions on the subject or asked during the presentation.  

In-class Quiz    There will be 4 in-class quizzes. 20 - 30 mins will be given for each quiz. Quiz should be consdiered as a small exam.

Exams      There will be two Midterm exams (in-class) and one comprehensive Final exam.  Please check the Course Calendar for the exam time and date.

*The passing grade for Physics majors is C and above. The actual grading scale may vary depending on numerous factors within +/- 2.5 points out of 100.

STUDENTS with DISABILITIES: Students who require accommodation for disabilities must first contact the Dean of Students Office. That office will provide documentation, which the student must bring to his/her instructors during the first week of the semesterContact the Disability Resources Center for information about available resources for students with disabilities.

COUNSELING and MENTAL HEALTH RESOURCES: Are you or your friends  in distress or facing difficulties completing the course?  Please contact the on-campus Counseling and Wellness Center at (352) 392 1575 ( or University Police 392 1111

ACADEMIC HONESTY: Each student is expected to hold himself/herself to a high standard of academic honesty. Under the UF academic honesty policy, unauthorized assistance or the use of unauthorized resources is strictly forbidden on work-for-credit. Although discussions among the students are highly encouraged, you are to work alone on all homework assignments unless specified differently. Fabrication or falsification of excuses or related documentation is also a violation of the UF academic honesty policy.  Violations of this policy will be dealt with severely. There will be no warnings or exceptions.

ONLINE COURSE EVALUATION: Students are expected to participate in course/instructor evaluations.  These evaluations are conducted online typically during the last 3 weeks of the semester.  Summary results of these assessments are available.
