The POISK Centre has hosted an annual General Physics section at the ’Physics and Progress’ young scientists’ conference at Saint Petersburg State University (October24—26, 2006).

The Conference has been organized by the Department of Physics, Saint Petersburg State University, and had 8 sections on different areas of theoretical and experimental physics. The POISK Centre’s section on General Physics was less limited in topics of the research and was dedicated to research problems in complicated unexplored physical phenomena. That made the meeting interesting not only for a few specialists, but for a bigger audience. Numerous attendees at the section have considerably inspired the discussions.

Most reports were made in English as it was the official language at the section. The conference targeted to motivate participants in research work and among attendees and reporters were many second or first year university students, but also postgraduate students. Andrey Uskov, Alexander Poretsky, Ilya Martchenko, Dmitry Martchenko, Andrey Selivanov, Ivan Yamschikov were among participants.

«During the conference, the participants have found new ways of improving their further works. More and more students join the POISK Centre activities and participate in its Olympiads. That indicates the growing interest in the activities that enable students to collaborate directly with university researchers. The opportunity to publish their results is also important», considered Dr. Elena Lebedeva, the POISK Centre president.

The abstracts book and the proceedings book are available here.

Recently founded POISK Centre clarifies its goals and strategies as Saint Petersburg State University hosts the selective Vserossiysky Turnir Yunykh Fizikov (Young Physicists’ Tournament) in Akademicheskaya Gimnaziya on March 22—27, 2004.

The Young Physicists Tournament (YPT) was first created by Evgeny Yunosov as an alternative to traditional Olympiads in physics. The tasks are proposed by International Organizing Committee (IOC IYPT) and do not have a predetermined unique answer.

When working on the tasks, secondary school students explore open scientific problems that require deep experimental and theoretical analysis of various physical phenomena. The participants have to defend their solutions against «opponents» at «Physics Fights», an analogy to a seminar or a scientific conference. However, the presentations at these seminars are graded by jury.

All in all, the Tournament has attracted 13 teams, more than it was typical in recent years. These teams were from Arzamas, Inta, Khanty-Mansiysk, Moscow, Novodvinsk, Pushkin, Saint Petersburg, Stavropol, Yekaterinburg, Zarechny.

This year’s selective event was hosted by Saint Petersburg State University. Venues for preliminary selective fights were in Peterhof (at Akademicheskaya Gimnaziya), while the finals took place on the Karelian Isthmus (at Baza Universitetskaya, a resort facility of Saint Petersburg State University, near Vyborg).

The jury included many team leaders and professors of leading Russian universities: Dr. V. Shamanin, Dr. Alexander Kurdymov, Dr. Robert Kolalis, Dr. Zinovy Uritsky, Dr. Elena Lebedeva, Dr. Boris Borisov, Dr. Sergey Pivovarov, Dr. Evgeny Denisov, Dr. Roman Panin, Dr. Vyacheslav Bozhevolnov, Dr. Sergey Vlasenko, Olga Inisheva, K. Shusharichev, A. Mukhachev, Elena Zauzolkova, N. Zhdanova, Nina Kusheverskaya, Igor Borodin, Dr. V. Vyun.

Dmitry Zhelezov (Saint Petersburg), Andrey Zheleznyakov (Staraya Russa, a member of Saint Petersburg team), Evgeny Kuznetsov (Yekaterinburg), Anton Teptsov (Inta), Andrey Naryshkin (Moscow), Arseny Lunyov (Saint Petersburg) were awarded for best individual ratings.

In the finals, held at Baza Universitetskaya, the three leading teams could choose their problems, without challenge procedure (required at a selective Physics Fight).

Team of Saint Petersburg, trained throughout2003—2004 by Dr. Elena Lebedeva and Ilya Martchenko, has won gold, while teams of Moscow and Yekaterinburg were awarded with silver. Teams from Saint Petersburg and Moscow are now nominated to represent the country at IYPT in Brisbane, Australia (scheduled to take place on June24-July1, 2004).

The Saint Petersburg State University and the POISK Centre express gratitude to everyone who made the organization of this competition possible.

An intense preparation and training of the Russian IYPT representatives begins.

July 1, 2004


The Russian team wins bronze medals and ties for the 4th place overall, showing an outstanding result at the 17th International Young Physicists’ Tournament held in Brisbane, Australia (June24-July1, 2004).

The victory at such a prestigious international competition is a first international success for the POISK Centre, a Russian university-based organization founded to promote open intellectual scientific competitions and to provide support in professional selecting and supervising the participating Russian teams.

«We felt a strong need in using completely new ways of training and supervising Russian teams at IYPT. By 2004, there was an urgent need in a university-based educative and research centre that would help to select and prepare a competitive team. We have to admit that the performances of certain Russian teams at recent IYPTs were incompatible with the scientific potential of our country and the role that Russia used to play in developing YPT as a new institution and a new type of competition. The POISK Centre is very proud for the 2004 success and hopes to implement many plans in providing professional, transparent, well-organized system of training Russian teams», said Dr. Elena Lebedeva, the POISK Centre president.

The IYPT is an annual research competition for secondary school students in their ability to solve complicated scientific problems that do not have a known certain answer.

«In order to succeed at an international competition, all participants need outstanding skills in spoken and written English, but also in so called ’English for Special Purposes’, namely the language of science and physical terminology. These excellent skills were made possible due to contributions by Ilya Martchenko, a YPT-veteransince 1999 and, currently a very motivated IYPT-activist, team leader and secretary-general of the POISK Centre», Elena Lebedeva noted.

«Best congratulations to the Polish team and their enthusiastic team leader, Stanisław Lipiński. We are happy to retain a very friendly cooperation with them since 2001, when we had held a joint Physics school. In 2002, and now in 2004, the Polish teams were the gold winners at IYPT. Best congratulations also to all of participants, including the Slovak and German teams who did excellent reports and finally prevailed over us with a narrow margin», Ilya Martchenko said.

Recent victories at the selective YPT in Russia and the extraordinary success at IYPT would not be possible without invaluable support from professors and students at Saint Petersburg State University who helped in preparation and made current achievements possible: Dr. Robert Kolalis, Dr. Evgeny Denisov, Dr. Boris Borisov, Dr. Sergey Vlasenko, Dr. Roman Panin, Dr. Alexey Pirozersky, Dmitry Martchenko, Pavel Ulyanov, Artyom Rusanov. The POISK Centre expresses gratitude to Dr. Sergey Pivovarov (Akademicheskaya Gimnaziya) for his ongoing activities to promote YPT.

The POISK Centre launches ’Scientific Inquiry’, a research competition for university students, and offers open problems that do not have a certain known answer.

A first selective seminar of the ’Scientific Inquiry’ Olympiad was held on December 21, 2004 at POISK Centre.

Dr. Robert Kolalis (the jury chair), Dr. Elena Lebedeva (the POISK Centre president) and Dr. Ivan Grigoryev (the vice-dean at the Department of Physics, Saint Petersburg State University) have welcomed the participants at the opening ceremony.

«The traditional physics Olympiads offer problems that must be solved in few hours or even minutes. These problems have a certain answer and would not make a difficulty for a skilled specialist. However, our problems are of different type. The participants have at least several months to cope with their research projects», explained Dr. Elena Lebedeva.

«These problems never had any predetermined answer. That is why they are especially interesting for physics students. They are challenging! For example, nobody has yet explained why a disk made of cesium nitrate, when cooled in liquid nitrogen, starts attracting metal objects», said Dr. Robert Kolalis, juror at the Russian Physics Olympiad, author of many such problems and the jury chair at the POISK Centre.

Intriguing research projects were presented by Ilya Martchenko, Dmitry Zhelezov and Ivan Yamshikov presented at the first POISK Centre’s selective seminar.

The POISK Centre welcomes university students to take part in the competition.

March 1, 2005


An English-language scientific seminar was hosted by POISK Centre. The discussed topics included the acoustical aspects of the Leidenfrost effect (by Ilya Martchenko), the quantitative description for Magnus effect (by Ivan Yamshikov) and the hydraulic jump theory (by Dmitry Zhelezov).

The organizers of the Seminar were very surprised when most attendees announced that they didn’t need any interpretation. Moreover, the audience has actively participated in the English-language discussions on these challenging physical problems.

Dmitry Zhelezov’s report has covered his computer simulation of the hydraulic jump, an effect that has only recently achieved an affordable theoretical description, while thenon-stationaryaspects of hydraulic jump remain unclear.

Ilya Martchenko has analyzed the acoustic waves that may be generated by a droplet suspended above a hot surface. His videos and fascinating experiments with liquid nitrogen have enjoyed a very warm reception of the audience.

Dr. Igor Mašek, who has been supervising English-language courses at Saint Petersburg State University for many years, said this and other POISK Centre’s activities are of invaluable importance to promote physics and motivate students to learn languages.

«We see more and more attendees and participants at our Seminars. The reports are of great interest to everyone. That is wonderful», said Dr. Robert Kolalis, the POISK Centre’s jury chair.

Ilya Martchenko wins at the finals of the ’Scientific Inquiry’ Olympiad, held on May 24, 2005 at POISK Centre.

The finals of the ’Scientific Inquiry’ Olympiad have concluded many seminars and selective stages. On May 24, 2005, three university students who had obtained the best results at the selective rounds presented their new research projects.

All three final reports have raised high interest of the jury and the audience. The detailed discussion has proven that the participants not only succeeded to explorenon-trivialphysical processes, but also to provide comprehensive theoretical explanation and defend their work on public. The discussion between professors and students after the reports was enormously helpful and has clarified the details of performed work and the plans for the further work.

Ivan Yamschikov has presented a research on the aerodynamics of boundary layers and the lift force during unstable circulation. The work by Arseny Lunyov concerned quite unexplored physical features of insects’ flight (asymmetrical oscillations of insects flight). Ilya Martchenko has presented his research on the Raleigh-Taylor instability and unstable behavior of liquid interfaces. Ilya Martchenko managed not only to propose an original theoretical approach to this beautiful phenomena but also to prove the correlation of his theory to experimental data, carefully analyzing the validity of the results.

After each report the participants have briefly analyzed pros and cons of their peer’s works. These discussions were also graded by the jury according to the rules of the competition. The difference in scores was very little and some judges wanted to award each of the finalists with a first prize.

«Many famous physicists: Bohr, Rutherford, Born, Heisenberg, Feynman, were interested in experiments when they were young. I will be very glad to know that in the future my students will invent something extraordinary», said Dr. Robert Kolalis, the jury chair.

«During past year, the POISK Centre’s achievements were very high. We have involved into research practices even the first-year students. The gained experience will be very important in their future life. Our seminars have helped them to strengthen their skills needed in diploma defense and further researches. We are glad that the Saint Petersburg State University has fully supported our activities», noticed Dr. Elena Lebedeva, the POISK Centre president.

«This competition helps to develop an active position in life and science», said Ilya Martchenko, the winner. «I have learned a lot in physics and mathematics and, moreover, in skills of public performance and in making my report clear and comprehensive. The ’Scientific Inquiry’ Olympiad requires heavy preparation but, as we can see, many students were not afraid of it».

«The finals enjoyed a very motivated atmosphere and both reports and discussions were of the greatest level. We are all eager to see the new problems at the beginning of the next POISK Centre’s Olympiad», an official statement said.

The finalists were awarded with diploma and valuable prizes.

The results of the final:

  • Gold — Ilya Martchenko (Saint Petersburg, Russia)
  • Silver — Arseny Lunyov (Pushkin, Russia)
  • Bronze — Ivan Yamschikov (Saint Petersburg, Russia).

POISK Centre welcomes students to participate in the next year’s Olympiad.
