Princeton Physics Program
Online physics program for serious and talented middle and high school students, providing structured exposure to undergraduate-level physics.

Our Philosophy: Encountering Physics as True Physicists Do
For many academically advanced students, school physics offers little opportunity for genuine intellectual exploration. The curriculum often emphasizes formulas and routine problem-solving, leaving little room for the creativity, curiosity, and conceptual depth that make physics such a fascinating discipline. As a result, students may never experience the subject as it truly is during the critical middle and high school years, when they are beginning to shape their academic interests and future aspirations.
For serious young students, physics should be more than a sequence of formulas and standard classroom problems. It should be a chance to encounter physics as it is: science’s most exciting and fundamental account of the nature of reality. At the Princeton Physics Program, we aim to give students the opportunity to ask ambitious questions, confront difficult ideas, and begin understanding how physicists have transformed humanity's view of the universe.
The Princeton Physics Program places students in a selective and intellectually challenging scientific environment. Students are introduced to physics from the quantum to the cosmological scale, from particles and atoms to stars, black holes, and the expanding universe. They examine not only established theories, but also the experiments, contradictions, and unresolved questions that led to their development.
Our approach enables serious learners in middle and high school to experience physics as physicists do: by questioning assumptions, constructing models, following mathematical arguments, testing explanations against evidence, and discussing difficult ideas with equally motivated peers. Through this process, students begin to see themselves not simply as learners of established science, but as potential contributors to its future.
The Structure
Course Levels
The Princeton Physics Program is offered across three levels to match students' scientific maturity, mathematical preparation, and readiness. Each level concludes with a project that allows students to synthesize ideas and demonstrate their learning.
We encourage students to select their level based primarily on their intellectual interests, academic preparation, and the areas of physics they are most eager to explore.
Level 1 – Introduction to the Physical Universe
Level 1 introduces students to the central habits of scientific thinking and the fundamental principles used to understand the physical universe. Students learn to reduce complex phenomena to manageable models and investigate questions across immense scales, from the motion of rockets and satellites to the behavior of atoms, stars, and galaxies.
The curriculum explores dimensional analysis, motion, forces, energy, gravity, orbital mechanics, light, stellar physics, quantum phenomena, and evidence for the Big Bang. It is designed to move students beyond standard school physics and provide an accessible first encounter with the conceptual depth of university-level study.
Recommended Grade: Grades 8-10, including older students with limited prior exposure to physics.
Preparation Benchmark: Comfort with basic algebra and scientific notation. Familiarity with introductory mechanics is helpful but not required.
Level 2 – Einstein's World and the Cosmic Beginning
Level 2 introduces students to the intellectual revolution that transformed physics during the twentieth century. Beginning with the apparent failures of classical physics, students examine how relativity, thermodynamics, and quantum theory challenged established ideas about space, time, matter, energy, and predictability.
Students develop the mathematical tools needed to study oscillations and waves, special relativity, mass-energy equivalence, entropy, the birth of quantum theory, and stellar evolution. The level emphasizes the relationship between mathematical reasoning, experimental evidence, and the emergence of new physical theories.
Recommended Grade: Grades 9-11, including advanced Grade 8 and Grade 12 students.
Preparation Benchmark: Strong algebra and familiarity with introductory mechanics. Experience with functions, vectors, or elementary calculus is advantageous but not required.
Level 3 – Quantum Theory and Astrophysics

The Schedule (Fall 2026)
All instruction—including both the Lectures and the Individual Tutorial —is delivered entirely online.
The program includes two integrated components:
Live Lecture: Students attend live lecture sessions held on a set schedule. Each session is conducted live and recorded, allowing students to revisit the material at any time.
Live Individual Tutorial: Students are encouraged to book one 30-minute 1:1 session per week on demand. These sessions provide personalized time for questions, clarification, targeted problem-solving, and feedback, supporting consistent progress throughout the course.
This structure allows students worldwide to access Princeton Physics Program while accommodating demanding academic schedules. Students unable to attend a live lecture can review the recording and use the 1:1 Tutorial Sessions to clarify questions and maintain steady progress.

Admissions
All applications are reviewed holistically by the Admissions Committee, with careful consideration given not only to academic preparation but also to each student’s commitment to mathematics, intellectual engagement, and readiness for rigorous study.
Fall 2026 Early Admissions Deadline: August 13, 2026 (Thursday)
Fall 2026 Regular Admissions Deadline: September 6, 2026 (Sunday)
All deadlines are at the end of the day in each applicant’s local time zone. Applications submitted in the Early Admissions pool will be prioritized.
Step 1: Submit Your Application
Complete the online application form. The applicant will be asked to select the level for which they are applying and respond to questions designed to help us assess their scientific background, mathematical preparation, readiness, and intellectual curiosity.
We generally encourage students to begin with Level 1 unless there is clear prior preparation. Students already familiar with Level 1 topics and with substantial formal coursework in related areas may consider applying directly to Level 2.
For Level 3, students must either have successfully completed Levels 1 and 2, or their equivalents, or demonstrate exceptional preparation in physics and mathematics.
Step 2: Admissions Committee Review (rolling basis)
The Admissions Committee convenes weekly to review each application submitted during the preceding week to determine each applicant's appropriate placement and overall fit for the program.
Step 3: Decision Day (around 10 business days after submission)
All applicants will receive an official admission decision around 10 business days after submission. Applicants may receive a deferral or rejection, a place on the internal waitlist, or an official offer letter. Successful applicants will generally be asked to complete enrollment within five business days before the seat is released to the next waitlisted student.
