Solutions

The solutions presented at the IYPTs, at regional competitions, and at related events, present a vast output of worldwide efforts in the pre-university research.

Although the competition means competition, these international efforts may be considered collaborative, as the participants receive criticism and impetus for further work though the opposition and review stages, and always have a solid feedback from their mates and team leaders, much alike to “real science.”

Some of the IYPT solutions were later skeptically revisited and retracted by authors as incorrect; many have never been preserved for the future; while others led to refereed papers in international journals.

The collection of solutions may be of interest to researchers in physics education, giving direct information on the motivation and achievements of students. It may also be helpful for the future team leaders and participants, showing examples of research strategies, structure of a presentation, or competitive levels to be achieved.

If you are a participating student, we expect from you the maximum responsibility in exploring the earlier solutions. They are not a textbook of “ready, free, and correct templates” and reflect, above all, the original ideas, original work, and original research results. A strict respect of the author’s moral rights must be a basic and undisputable priority.

“During the competition, teams may draw ideas from presentation of other competing teams; however proper citing is essential”, say the recent guidelines for participants. This applies, certainly, to the old solutions and to any other sources of information.

It may be a very good idea to film the today’s presentations for the future. Although until recently “taking of audio and video recordings” was allowed “only in the case of own performances,” the restriction has been significantly relaxed as of 2011, when “each team participating on the PF shall have the opportunity to take pictures and film the whole fight.” The filmed presentations would reflect the today’s IYPTs and would become an increasingly precious record as the time passes by.

Our policy is to catalogue only those solutions that were explicitly and deliberately intended for public access and, when possible, are openly available from their originators or in published sources. A few solutions provided by the problem authors themselves are also indexed in this section.
