Explorer Competition

What is it?

Every year, hundreds of high school-level students from around the globe form teams and compete by responding to an open-ended research-based assignment containing questions inspired by groundbreaking discoveries in physics, and submit their work after a two week-long period in the form of a report. This event is called the Physics Unlimited Explorer Competition.

The 2021 Explorer Competition took place in February/March. Beginning with the 2022 edition the event takes place in April. Explorer 2023 took place April 1(2) - 18, and the assignment can be viewed here.
