WoPhO Problem Competition
Anyone who has ideas for good problems – theoretical or experimental – please note that there is a problem competition for the World Physics Olympiad. The difficulty level of these problems should be approximately the same as for the IPhO. There are two prizes for experimental problems, à 25000 USD, deadline 31st May, and three prizes for theoretical problems, à 20000 USD, deadline 30th June. More details can be found at the WoPhO home page.
