× The 2018 Premier Competition has taken place on November 18, 2018, hosted in four countries. Results from across global sites are now available here.


Launched in 2017, the non-profit organization is run by alumni of Princeton University who initially organized the Princeton University Physics Competition. While the operation of Physics Unlimited is entirely independent of Princeton University, the required level of coordination with relevant organizers of PUPC is maintained in order for our events to be successful.

At this time, Physics Unlimited is in charge of overseeing three types of events:

  1. the Explorer Competition, a research-based online assignment that students have a week to complete;
  2. the Premier Competition, a single-session, 1.5-hour international version of PUPC;
  3. the PhysiKarma initiative in partnership with Expii, an ongoing, academically rewarding - and stress-free - way to demonstrate your physics knowledge; PhysiKarma earners will be recognized on the 15th day of each month.
We are also exploring the feasibility of organizing a new type of event: the Physics Makeathon, a hands-on project-based assignment that would incorporate elements of both maker space and hackathon. If you would like to be involved in any role, please consider answering a short questionnaire.

In all cases, to create an account, please proceed to this page. Once you have confirmed your e-mail and are logged in, please submit the short registration form through our portal, selecting the type of event and location.

If you would like to volunteer in any capacity with us, or offer to establish a potential regional site, please fill out our Get Involved form. Any remaining questions, clarifications, or requests can be e-mailed to directors@physicsu.org or specific addresses found on the Contact page. We look forward to hearing from you and to your participation in our events!
