General criteria for evaluating the competition papers:
Papers should be of regular research character in physics (physics should dominate in the papers - that refers to all the recognised competition papers, not to the awarded papers only). They should contain new, original and interesting results obtained by the Author either in theory or in experiment or in constructing devices (or instruments), the results should be presented in an appropriate way, characteristic for research papers. The papers should be ready for publication without any changes or after minor changes of editorial character only.
Category: Research papers
The same as above, but the paper is not ready for publication without more or less important changes that exceed editorial character only.
Interesting contributions or interesting descriptive papers or interesting papers aiming to popularise some topics (the papers in this category should contain at least a new approach to the topic of the paper). The papers should be correct with regards to physics contents and written in good English. (Good English is required from all the recognised papers, but its role in this category is somewhat greater.)
Interesting devices, instruments and other constructions that - at least in principle - are not absolutely new. They, however, should contain some interesting solutions or other interesting details. (The new constructions may be awarded.)
