How to Apply

Students in the College of Arts & Sciences do not declare a major until their sophomore year. Nevertheless, students can indicate their interest in majoring in physics on their application for admission to Cornell University. Information on applying to Cornell can be found at the College of Arts and Science and the main Cornell Admissions site.  Click the Cornell Days Physics 2019 schedule for classes you can sit in on,  faculty office hours, and informational sessions conducted by our Society of Physics StudentsPhysics 1116 is not available to visit on April 26.

Freshmen Interested in Majoring in Physics

Incoming freshmen interested in majoring in physics should attend our Orientation for Prospective Physics Majors time TBA. Freshmen can also request a current junior or senior majoring in physics to serve as an informal peer advisor. Prospective majors are encouraged to join the student-run Society of Physics Students, and are also welcome to discuss pre-major course selection with the Director of Undergraduate Studies.

Sophomores Declaring the Physics Major

Sophomores meeting the entrance requirements for the major (at least 2 physics and 2 math courses taken at Cornell with an average grade of B- or higher in the aforementioned courses) may apply to the major by following these steps:

1) Download and fill out both sides of the Physics Major Form here:  After completing as much of the form as possible, print the form and bring it to the meeting with the DUS, Prof. Liam McAllister to complete their physics major form and admission to the major.

2) Choose one or two possible physics major advisors.  If students do not have any preferences, a major advisor will be assigned to them by the DUS.

3) After meeting with the Director of Undergraduate Studies, new majors will meet with their major advisors to go over their Physics Major Course Plan (2nd page of Physics Major Form).

4) After having their Course Plan approved by their advisor, students will return the Major Form to Sue Sullivan (sfc1@cornell.edu) in the main Physics Office (Clark 117).

Requirements at a Glance

Honors and Senior Thesis Option

A student may be granted honors in physics upon the recommendation of the Physics Advisors Committee of the physics faculty. There is no particular course structure or thesis requirement for honors.  However, we do have a senior thesis option starting with our current junior class.

Thesis Overview

Below is an overview of the basic timeline that physics majors intending to pursue a senior thesis should follow.

 

FRESHMAN &

SOPHOMORE YEARS

A thesis is a rewarding experience and your opportunity to do cutting edge science, which can take a lot of time. You should plan to 1) already be involved in research by your junior year, and 2) plan your schedule to leave large blocks of time for your thesis research

JUNIOR YEAR  FALL SEMESTER

Students intending on pursuing a senior thesis should ideally already be working in the research group in which they intend to write a senior thesis

JUNIOR YEAR  SPRING SEMESTER

  • Students ask their research advisors if they will supervise senior thesis
  • After obtaining faculty permission, students submit a thesis proposal by  APRIL 1
  • DUS approves thesis proposals, in consultation with faculty advisors

SUMMER

Students working on a senior thesis are encouraged to consider staying over the summer to work on their thesis research (dependent on funding)

 

SENIOR YEAR 

FALL SEMESTER

  • Students enroll in  PHYS 4498 : Senior Thesis I (3 credits min)
  • At the end of the semester, students submit 1 pg update to their advisor & DUS
  • All students participate in a poster session and/or short presentations based on their current thesis research on the last Friday of the fall semester

 

SENIOR YEAR 

SPRING SEMESTER

  • Given completion of the requirements in the Fall, and satisfactory performance in Fall PHYS 4499, students will then enroll in  PHYS 4499 : Senior Thesis II (3 credits min)
  • Students give a 15 minute “thesis defense” attended by other majors, faculty, and DUS in mid­April
  • Students submit their written thesis to the DUS and faculty advisor by  MAY 1  

First Steps towards the Senior Thesis

  • Students should already be working for faculty in their junior year to be considered as strong candidates for a senior thesis
  • Students & faculty advisor must mutually agree  upon a thesis topic before students submit a senior thesis proposal. Faculty are under  no obligation to supervise a senior thesis
  • Students submit a one page thesis proposal online to the DUS by  April 1 of their junior year
  • All physics majors (inside or outside concentrators) can pursue a senior thesis. Any physics faculty (and members of the field of Physics) can supervise a senior thesis. Students pursuing research outside the physics department can pursue a senior thesis, provided the thesis topic is related to physics. The DUS will determine whether thesis topics supervised by faculty outside the physics faculty are appropriate for a senior thesis. 
  • After reviewing the thesis proposal, student’s GPA, and any recommendations from the student’s potential thesis advisor & faculty advisor, the DUS will approve students to register for  PHYS 4498 : Senior Thesis I. Students will then enroll in  PHYS 4498  in the fall semester of their senior year and  PHYS 4499: Senior Thesis II in the spring semester.

Eligibility To Pursue Senior Thesis

Students should have a minimum of a 3.3 GPA in order to pursue the senior thesis

Students should have completed  all of their Core Requirements by the beginning of the senior year (exceptions made for students having only one Core Requirement remaining)

Students should fill out their senior thesis proposal by  April 1 of their junior year, with the written permission of their faculty major advisor & thesis advisor. All thesis proposals are ultimately decided by the DUS. 

Students should already be actively engaged in research leading towards their senior thesis by the spring of their junior year

Students should be pursuing thesis research either within the physics department, or if outside the physics department, that is physics­related (at the discretion of the DUS)

 

PHYS 4498 : Senior Year, Fall

  • During the semester, students will conduct their thesis research wholly under the supervision of their thesis advisor, in a manner similar to regular independent study / research (4490).
  • Near the end of the semester,  students must submit a 1 page written status report  on their thesis research, signed off by their thesis advisor, and to be submitted to the DUS for review.
  • At the end of the semester,  students will also give short presentations (10 minutes) or a poster session , attended by other thesis students, to provide an update on the status of their thesis research
  • At the end of the fall semester, a grade of “R” is given. That grade of “R” is replaced with the grade for PHYS 4499 when 4499 is also completed.

PHYS 4499 : Senior Year, Spring

  • Enrollment for the spring semester of PHYS 4499 is contingent on completion of the 1 page report, participation in the presentation / poster session, and strong performance (A­ or higher) during the Fall semester of PHYS 4498.
  • During the semester, students will conduct their thesis research wholly under the supervision of their thesis advisor, in a manner similar to regular independent study / research.
  • Sometime in mid­-April, students will present a 15 minute “thesis defense” to other thesis students, faculty, DUS, and any other interested parties. 
  • Students will submit their written thesis, approved by their thesis advisor, to the DUS by  May 1st.

Completion of Senior Thesis

  • The written thesis should be a minimum of 25 pages (not counting Abstract, TOC, Acknowledgements, Bibliography, or Appendices).
  • The thesis should be written and formatted following the Cornell Thesis and Dissertation Guidelines (https://test­graduate­school.pantheonsite.io/wp­content/uploads/2018/05/Thesis­and­Dissertation­Guidebook_sp 2018.pdf) ,  preferably in LaTeX
  • With approval of the student & advisor, PDFs of the completed theses will be archived and/or posted.
  • If the student’s research work towards a senior thesis has resulted in a peer­reviewed publication where the student was the lead author, it is acceptable to substitute that publication, together with a brief introduction section, as the written senior thesis (the 25 page minimum is waived). The thesis itself should still be formatted following the Cornell Thesis and Dissertation Guidelines.
  • The senior thesis will be considered complete when 1) the oral “thesis defense” is completed, 2) the written thesis is turned in, and 3) at least 6 credits of  PHYS 4498 + PHYS 4499 are completed. 
  • Final grades for  PHYS 4499 will be assigned by the DUS, in consultation with the thesis advisor.  

Additional Notes

  • A maximum total of 4 credits from all research­related classes ( PHYS 4490 : Independent Study OR  PHYS 4498 / 4499 : Senior Thesis ) can be used towards the inside or outside concentration. For instance, if a student has already used 4 credits of  PHYS 4490 towards his/her concentration, they may not also use  PHYS 4498/4499 credits towards their concentration. 
  • While enrolled in PHYS 4498/9, students are not permitted to also be performing that work for pay. 
  • The senior thesis will be factored into the determination of Latin honors at graduation. The thesis will not be the sole determining factor (students graduating without a thesis can graduate with high honors), but it will be factored in to some extent.

 

 

Double Majors

Students are welcome to pursue a physics major concurrently with another major; either in the college of Arts and Sciences or in another college through the concurrent degree option. Any course used to satisfy a requirement of another major may be used in satisfaction of physics major requirements only if the student’s concentration is within physics.

Courses

The concepts and methods of physics impact nearly all areas of human endeavor. The Department of Physics offers courses in physics for the entire Cornell community. There are general education courses for non-scientists, well-designed introductory sequences for science and engineering majors, more advanced courses for physics majors, and rigorous programs of graduate study, up to doctoral-level independent research.

Minor

Non-physics majors in all Cornell colleges are eligible to earn a Physics minor.  To apply to the Physics Minor, stop in 117 Clark Hall to get an application, fill it out, and bring it with you when meeting with the Director of Undergraduate Studies during office hours or contact physicsdus@cornell.edu to schedule an appointment.

Admission to the minor requires:

i) An average of B- or better in two of the introductory physics courses

Requirements for the Minor

To earn a minor in physics, a student must complete the following requirements, with a minimum grade of C-: 

1. Completion of one of the 3-course Introductory Sequences (including special relativity, either in 1116 or 2216)

2. Quantum Physics I (Physics 3316)*;

3. An intermediate physics lab course, chosen from PHYS 3310, 3360, 4410, AEP 2640, BEE 4500, or ASTRO 4410.

4. One additional 3000+ level PHYS course of at least 3 credits.

*Students with credit for another quantum mechanics class (such as AEP 3610, CHEM 2870-2880 or ECE 4060) may substitute a different 3000+ level physics course for PHYS 3316.

Undergraduate Awards

Each year the Department of Physics gives five awards to outstanding undergraduate students:

The Yennie Prize
An award to the outstanding senior student majoring in Physics who shows unusual promise for future contributions to physics research, and who intends to earn the doctorate.

Professor Yennie was a long-time member of the Cornell Physics faculty, internationally known for his work in theoretical physics, especially in quantum electrodynamics.  He was also known to his students and colleagues as a wise and dedicated teacher.  This prize is endowed in Professor Yennie’s memory by his family and colleagues. The 2019 Yennie Prize was awarded to Benjamin Roberts.

Kieval Prize
Prize awarded to a senior Physics student who demonstrates unusual promise for future contributions to the physics research.

The funds for this award were given by the late Harry S. Kieval, Cornell ’36, a long-time professor of mathematics at Humboldt State University in Arcata, California.  The 2019 Kieval Prize was awarded to Noah Sailer.

Hartman Prize
This prize honors Paul Hartman, who was a long-time professor in both departments and who played a crucial role in teaching experimental physics to students in both programs.  The prize is awarded to recognize outstanding work in experimental physics by an undergraduate in Physics and/or Applied and Engineering Physics. The 2019 Hartman Prize was awarded to Benjamin Roberts in Physics and Yonghun Lee in Applied and Engineering Physics.

Erik Cassel '90 Prize
An award to an undergraduate majoring in physics who has demonstrated exceptional creativity and promise in applying computer programming to a project in physics or related fields. This award was established in memory of Erik Cassel, Cornell '90.
