tlemcen: the caravan of physics in the Algerian west

tlemcen: the caravan of physics in the Algerian west. The university Abou Bekr Belkaid de Tlemcen in collaboration with the French arts centre and the French company of physics organizes a caravan of physics through the western area of the country It is a question of making known for audience the largest possible progress, the importance and the stakes of this large side of science. This caravan will remain 15 days in each university of the west will say Hafid Aourag professor and regional operator following the established calendar: from the 16 at September 28 university of Tlemcen, of September 30 to October 12 at the university of Beautiful Sidi Abbès, of the 14 at October 26 at the university of Saîda, of October 28 to November 9 at the university of Chlef, the 11 at November 23 at the university of Mostaganem, of November 25 to December 7 at the university of oran, final December 9 to December 11 Olympiads of physics. Activities are programmed at the time of the passage of the caravan: exposures, conferences, projection, Olympiads. Within the framework of the world year of physics, a certain number of conferences will be proposed on physics and its applications, its history and that of the physicists, in all Algeria, in the school establishments, the universities and the arts centres (physics in danger, physics and life, physics and Materials), the scientific film projection, which Einstein did not know yet the Noir holes, the Spatiale adventure. For the Olympiads for this year, two types of contest will be carried out better practical realization (crystalline structures), a competition open (questionnaire). For the practical realization, two stages with the interregional contests with selection of the finalists. The jury wonder of many councils for the improvement of the service for the final. The finale of the contest for a score of groups during two days with Tlemcen at semi December. The presentation of a model (crystalline structures) 10 minutes of presentation by the group of the model, 20 minutes of discussion with the jury, 10 minutes devoted to the questions about work completed, 10 minutes abstract enter members of the jury and pupils around the experiments, a report of a score of pages must be addressed to the rapporteurs before. Criteria of the jury: the quality of a future scientist, the clearness of the presentation, quality of the experiments, rigour of the step of research, team work. For the competition open, the Olympiads are competitions intended for all the students of education secondary, higher, general or technique. The engagement of the candidates is done preferably on the initiative of their professors of physics. The competitions proceed on an individual basis and not by team. The program of the contest: Mechanics: Concept of pression.hydrostatique.pousée of Archimedes. Simple levers and machines. Law of Hooke (springs). Law of solid friction (F=k.n). Rectilinear motions: Mru and Mruv, speed and instantaneous acceleration. Movements with two dimensions: composition of two uniform movements, horizontal shooting. Compostion and decomposition of forces. Laws of Newton: principle of inertia, fundamental law of dynamics, principle of the reciprocal actions. Work and power of a force. Kinetic, potential of elastic gravitation and potential energy. Law of universal gravitation. Laws of Kepler. Ballistic shooting. Periodic phenomena: period, frequency, harmonic oscillator (simple pendulum, arises). Thermal energy: thermometry, dilations, calorimetry, laws of perfect gas. Conservation of energy. For optics: Laws of the reflexion and refraction, total reflexion. Images formed by the plane mirrors and the lenses. Lenses (formula of conjugation, growth). As for electrostatics: Law of Coulomb, electric field. Electrokinetic and electric circuits. Electromagnetism: sources of magnetic field, forces of Laplace and Lorentz, magnetic flux, Faraday and Lenz's laws and self-induction. Electric transformer. appear in the program of the contest. For the exposure, it is proposed an interactive exposure made up of 18 contemporary experiments of physics and ideas of workshops or the visitor invited to handle by itself. It is accompanied by 15 posters of the exposure ?to the horizons of physics ?. This exposure makes to the visitors a thorough analysis of the search for these fifty last years. It is necessary to point out that this caravan of physics furrowed already the universities of Constantine, to Me sila, Annaba, Boumerdes, national Ecole Polytechnique of Kouba. The operator of the area of the east is professor Mimouni Djamel of the university Mentouri de Constantine. 20.09.2006 Mohamed Gadiri.
