Updated at 7.08pm: Hong Kong students have won a gold, silver, two bronze medals and received an honourable mention at the 36th International Physics Olympiad in Spain. A government spokesman said on Tuesday this was the second time a Hong Kong team won prizes at the Olympiad. Last year, Hong Kong won a gold medal and the 'President's Award' for best performance. The spokesman said the Hong Kong team, comprising five secondary school students, had received intensive training in three phases for nine months. They were led by Professor Yang Zhi-yu of the Hong Kong University of Science and Technology. They will return to Hong Kong on Wednesday. The International Physics Olympiad is an annual physics competition for high school students. They compete as individuals, and must sit for intensive theoretical and laboratory examinations. For their hard work, the students can be awarded gold, silver, or bronze medals or an honourable mention. The first Olympiad was held in Warsaw, Poland in 1967. Hong Kong students traditionally perform extremely well in international physics and maths competitions and examinations.
