ABOUT:
The International Physics Olympiad (IPhO) is an international physics competition for secondary school pupils. The first such competition was organised by Prof. Czesław Ścisłowski in Warsaw (Poland) in 1967. Since that era the International Physics Olympiads have been organised, with few variations that will be discussed later, in a different country every year.
