The International Young Physicists' Tournament (IYPT)[1], sometimes referred to as the "Physics World Cup", is a scientific competition between teams of secondary school students.
Discussion-based sessions are called Physics Fights and the performances of the teams are judged by expert physicists.
As long as they stay within the broadly defined statement of the problem, all routes are legitimate and teams will be judged according to the depths reached by their investigations.
Following its European roots, the tournament expanded globally, with the first non-European event held in Brisbane, Australia, in 2004.
The structure of these Fights can be compared to the group phase of a football competition (e.g. FIFA World Cup).
