The International Physicists' Tournament (IPT) is a physics competition for undergraduate students, bachelors or master level (or equivalent), in which students representing their nation and institution have typically 9 months to solve a set of challenging unsolved physics problems, then present and defend them to other teams.[1] The tournament originated in Ukraine in 2009 between Ukraine and the Russian Federation, but it has since grown to encompass numerous countries spanning multiple continents.[2] It was initially inspired by the International Young Physicists' Tournament (IYPT) and follows a similar model. Undergraduates may be accompanied by team leaders, who are usually academic research staff or doctoral research students.
