On September 1, in the Victory Park on Poklonnaya Hill, we will take part in the 16th Moscow Press Festival.
A whole media town will appear on Poklonnaya Hill with thematic zones devoted to popular headings of newspapers and magazines: about business, books, children, hobbies, sports and health. The digital zone will feature electronic publications and online media. The festival will host master classes, presentations, lectures, games and other events. Publishers will prepare meetings with their authors and media personalities, contests, surprises and gifts. Anyone can get a preferential subscription to any newspaper or magazine that he likes. The Moscow Press Festival is held for the sixteenth time. His main goals are to popularize reading and expand the audience of publications, increase interest in journalism and demonstrate modern technologies that are used in the media.
Dozens of publishing houses and media companies, including “Arguments and Facts”, “Moskovsky Komsomolets”, “Komsomolskaya Pravda”, “Kommersant”, TASS, “Rossiyskaya Gazeta”, “Evening Moscow” and many others will take part in the traditional press festival on Poklonnaya grief, which this year will be held on September 1. The festival will take place 16 (!) Times, and, although it has retained its affiliation to the newspaper industry in its name, the scale and nature of the event changes every year, as do the media themselves, which already interact with readers in a variety of formats, starting from text to paper to video. So this year, for the first time, a separate Digital-zone will appear at the festival, which will set a new bar in the development of the festival as a unique annual platform for the meeting of editors with readers.
The main theme of the event will be the slogan "Meet what you read about." The entire territory of this media city will be divided into thematic areas that will correspond to headings in newspapers or on news sites. A rich and exciting program will be waiting for visitors in the areas of "Business", "Digital", "Hobbies", "Children", "Sport and Health" and "Books".
Thus, in the Business sector, a master class in journalism will be held by one of its most famous representatives, a columnist for the Moskovsky Komsomolets and a member of the Public Observation Commission, Eva Merkacheva. The session of Rossiyskaya Gazeta will also be devoted to broad legal issues, and experts invited by the publication of the traffic police Stop-Newspaper will tell all about road safety.
A well-known Russian meteorologist, director of the Hydrometeorological Center of Russia, Roman Vilfand, will share his vision of climate change during the session of the publication Arguments and Facts. Among other topics in the Business sector are the development of trust funds, the role of the industry press in the construction industry, postal business and others.
In the Digital sector, journalists and digital marketing experts will share the secrets of successful blogging, promoting start-ups in schools, and producing multimedia data journalism. The cases will be presented by the heads of the digital directions of TASS, Komsomolskaya Pravda, Moscow Media Holding, Izvestia ICC and Prosveshcheniye publishing house.
The authors of top publications will acquaint visitors with the odyssey of their fascinating journeys and unexpected meetings in the “Hobbies” section, and at the “Children's” playground, young guests will have to wait for lots of pleasant surprises and meetings.
In the thematic sector of the "Book" it will be possible not only to get acquainted with the novelties of popular science and school literature, but also to learn a lot of interesting things about the production of books.
And, of course, what a holiday without sports. Visitors to the "Sport" zone will learn a lot of useful things about healthy nutrition, and will also receive recommendations from experienced trainers in keeping fit.
The festive atmosphere will be complemented by the “Peoples of Moscow” music festival from Vecherka, as well as a concert dedicated to the 40th anniversary of the publishing house AiF.
All fans of mathematical polyhedra will be able to independently make models of polyhedrons and take them with them.
Archimedes, a scientist from the Ancient Greece, discovered 13 types of polyhedra, called now as Archimedean solids, which are also referred as semi-regular polyhedra.
Each of them is limited by different types of regular polygons where the polyhedral angles and identical polygons are equal. Furthermore, the same number of equal faces meets at each vertex. In the same order each of these solids can be inscribed into a sphere.
In natural environments regular polyhedra can be found in the form of crystals (minerals).
Sodium sulphate reminds the shape of tetrahedron.
Quite often a question about a practical use of paper models pops up. What is the point of paper modeling?
One can specify the following mathematical characteristics in each of the five Platonic solids:
1. The radius of the sphere circumscribing the polyhedron;
2. The radius of the sphere inscribed in the polyhedron;
3. The surface area of the polyhedron;
4. The volume of the polyhedron.
A polyhedron is a solid bounded by flat polygons, which are called faces. Sides of the faces are called edges, and their corners are called as vertices. Depending on the number of faces one can specify tetrahedron (4 faces), pentahedron (5 faces), etc. A polyhedron is considered to be convex if it is located on one side of the plane of each of its faces. A polyhedron is called regular if its faces are regular polygons (i.e., where all sides and angles are equal) and all polyhedral angles at the vertices are equal. There can be found five types of regular polyhedra: tetrahedron, cube (regular hexahedron), octahedron, dodecahedron, icosahedron.
Architects have used the elements of polyhedra in designing their constructions since ancient times. Nowadays this approach distinguishes buildings among thousands of others.
The Ministry of Defense in USA has the shape of a regular pentagon.
Is it possible to make up an icosahedron using more simple polyhedra?
A new and unusual way of making a model of Stellated polyhedron was discovered by a German mathematician and astronomer Johannes Kepler in 1619.
The founders of the town called Mirniy, situated in Russia in Arkhangelsk region, put an image of the polyhedron, “big dodecahedron”, on to the flag and emblem of their town.
