Information and Policies

Academic Advising for the Program Expand and Collapse

The department undergraduate advisor ([e-mail]) works closely with students interested in pursuing the major to ensure that they begin the program immediately and follow the appropriate steps toward its completion.

Getting Started in the Major Expand and Collapse

Students begin the major with PHYS 5A, after having completed MATH 19A or equivalent. (Students who take PHYS 6A instead of PHYS 5A, and do very well in it, may contact the department chair for permission to enter the major.) Students are strongly encouraged to begin their major coursework in their first quarter. Those who start later should consult the department undergraduate advisor and Alternatives. Students who do not begin the lower-division requirements during their first year will have difficulty completing the program within four years.

High school students coming directly to UC Santa Cruz should emphasize their mathematics preparation with the expectation that they will take calculus, MATH 19A, before their second quarter at UC Santa Cruz in order to take the Physics 5 series in time. Students who come to UC Santa Cruz with credit for MATH 19A will be able to start the Physics 5 series in the first quarter. The courses in the PHYS 5 and PHYS 6 series are offered multiple times per year.

Program Learning Outcomes Expand and Collapse

Program learning outcomes (PLO) summarize the most important knowledge, skills, abilities, and attitudes that students are expected to develop over the course of their studies. The program learning outcomes communicate the faculty’s expectations to students, provide a framework for faculty evaluation of the curriculum based on empirical data, and help improve and measure the impact of implemented changes. Students graduating with a B.S. in Physics (Astrophysics) will demonstrate:

PLO 1. Ability to solve problems using concepts in classical and quantum mechanics, statistical mechanics and electromagnetism.

PLO 2. Proficiency in mathematics and the mathematical concepts needed for a proper understanding of physics.

PLO 3. Ability to take measurements in a physics laboratory and analyze the measurements to draw valid conclusions.

PLO 4. Ability to communicate scientific content effectively, both orally and in writing.

Major Qualification Policy and Declaration Process Expand and Collapse

Major Qualification Expand and Collapse

To qualify to declare the physics (astrophysics) major, students must achieve a cumulative grade point average (GPA) of 2.70 or greater in the following courses, or their equivalents:

PHYS 5A	Introduction to Physics I	5
PHYS 5B	Introduction to Physics II	5
PHYS 5C	Introduction to Physics III	5

When determining qualification to declare the major:

• All courses must be taken for a letter grade.
• If PHYS 5A is satisfied with AP credit based on an AP examination score of 5, students may substitute a grade of A for PHYS 5A when calculating their cumulative GPA.

• If PHYS 5C is satisfied with AP credit based on an AP examination score of 5, students may substitute a grade of A for PHYS 5C when calculating their cumulative GPA.

• Students with two or more grades of NP, C-, D+, D, D-, or F in the major qualification policy courses are not eligible to declare even if the courses are retaken and the grades replaced.

Students who achieve a GPA of 2.66 or higher (but less than 2.70) in the three courses may declare the major if they receive a B or better in PHYS 5D.

Appeal Process Expand and Collapse

Students who are informed that they are not eligible to declare the major may appeal this decision by submitting a letter to the department chair by the later date of either 15 days from the date the notification was sent, or one week after the start of instruction during the quarter after the final relevant grade was received (generally in PHYS 5C or PHYS 5D). They also must arrange to meet with one of the faculty mentors listed for Declaring the Major. Within 15 days of receipt of the appeal, after consulting with the faculty mentor, the department chair will either finalize the denial of admission or specify further conditions for admission, and will notify the student and their college of the decision. For more information about the appeal process, see Appeal Process.

How to Declare a Major Expand and Collapse

Students should submit a petition to declare as soon as they complete the major qualification requirements or reach their declaration deadline quarter (whichever comes first).

Students petitioning when the campus declaration deadline is imminent (i.e., in their sixth quarter, for students admitted as frosh), will either be approved, denied, or provided with conditions (e.g., completion of some courses with certain grades) that will be resolved within at most one more enrolled quarter, even if they have not completed major qualification courses.

All students are required to review their academic plan with a faculty mentor prior to declaring the major. For instructions on petitioning to declare, go to Declaring Your Major.

Transfer Information and Policy Expand and Collapse

Transfer Admission Screening Policy Expand and Collapse

The following courses or their equivalents are required prior to transfer, by the end of the spring term for students planning to enter in the fall:

PHYS 5A	Introduction to Physics I	5
PHYS 5B	Introduction to Physics II	5
PHYS 5C	Introduction to Physics III	5
MATH 19A	Calculus for Science, Engineering, and Mathematics	5
MATH 19B	Calculus for Science, Engineering, and Mathematics	5
MATH 23A	Vector Calculus	5

A minimum GPA of 2.7 must be obtained in the following courses

PHYS 5A	Introduction to Physics I	5
PHYS 5B	Introduction to Physics II	5
PHYS 5C	Introduction to Physics III	5

In addition, the following course is recommended prior to transfer to ensure timely graduation:

PHYS 5D

Introduction to Physics IV

5

Prospective students are also encouraged to complete the Intersegmental General Education Transfer Curriculum (IGETC) or to complete all UC Santa Cruz general education requirements before matriculation.

Getting Started as a UCSC Transfer Student Expand and Collapse

Transfer students admitted to UC Santa Cruz in the physics (astrophysics) major who have satisfied the above screening requirements may declare the major immediately upon arrival at UC Santa Cruz. They should contact the undergraduate advisor to draw up an academic plan. Students who are proposed in a different major (other than physics or applied physics) and have advanced standing when they come to UC Santa Cruz require permission from the department to change into the major.

Letter Grade Policy Expand and Collapse

All courses used to satisfy the physics (astrophysics) major requirements must be taken for a letter grade, except the programming requirement.

Double Majors and Major/Minor Combinations Policy Expand and Collapse

Students who complete a major sponsored by the Physics Department cannot complete a second major sponsored by the Physics Department or a physics minor.

Honors Expand and Collapse

The department awards "honors" (3.5 grade point average or better) and "highest honors"(3.8 grade point average or better) to top graduating students each year. The department also awards "honors" for outstanding work on the senior thesis, made upon the recommendation of the faculty thesis advisor.

Timely Graduation and Alternative Plans Expand and Collapse

• Students planning a senior thesis should find a faculty thesis advisor as early as possible, but no later than the beginning of the senior year for four-year students or the beginning of the second year for transfer students. For further information about the senior thesis, see Senior Thesis.
• Students who join a major program of the Physics Department with some of the required courses completed, or have room in their program for additional courses, should consult with the Physics Department undergraduate advisor.
• Students who fall behind the planners should consult the Physics Department undergraduate advisor and Alternatives.
• All the transfer major planners assume that IGETC has been completed in community college, or has been partially completed and can be finished while at UC Santa Cruz (including summers).
