RIO – Ice crystals are among the most beautiful creations of nature. The hexagonal structures have patterns as complex as they are unique: never two have been found. The crystal forms around a single particle of dust, formed by moisture and by the many temperature variations in the clouds. "Mathematics is related to a lot of beautiful things," says Étienne Ghys of the Institute of Pure Applied Mathematics (IMPA), attached to the Ministry of Science, Technology, Innovation and Communications. . He will give a public lecture on snowflake training at the International Congress of Mathematicians, which begins Wednesday in Rio, and will bring together at least 2,500 specialists. "Mathematics has nothing to do with formulas, equations and ugly accounts, but with beauty and nature."
It is the first time that the international event, considered the most important of mathematics, will take place in a country of the southern hemisphere, unmistakable sign of Brazil's prestige in the region. And the main concern of the organizers is precisely to seize the opportunity to demystify the subject, revealing to the public its most beautiful and pleasant side. The event will go until 9
"The congress will not only celebrate the prestige of mathematics, but also to think about the future, there is much to do," says the director of the 39; IMPA and organizer of the event, Marcelo Viana. "We want to use the congress to bring mathematics closer to society, to deconstruct this negative image, to present a more friendly approach."
The congress was created in 1897 in Switzerland and is held every four years. suspended only during the world wars). During the event, the winners of the Fields Medal, the "Nobel Prize in Mathematics" and other international awards are announced. With Carioca Artur Ávila, the country has already won the Fields once in 2014. Fernando Codá, who works at Princeton University (USA), is considered another Brazilian reference in the region.
Women and Numbers During the nine days of the event, there are 1,200 conferences and round tables. There will also be about 40 parallel scientific events, including the World Meeting of Women in Mathematics, which will address gender issues. "In fact, Brazil even has a high number of women in mathematics compared to other countries," said Carolina Behring of Araujo, the only woman among the 47 researchers at IMPA. . "You go to a congress and there are less than 10% of women Why are not we represented?"
The popularization of mathematics is the theme of the IMPA-Serrapilheira Lecture Series, open to the public. The relationship between art and mathematics will be another subject. "We have developed mathematical algorithms that can be used for many purposes in both art and conservation, for example through a number of image badysis tools," explains Ingrid Daubechies, a Belgian who she works at the University of Duke (USA) and the first woman to chair the International Mathematical Union between 2011 and 2014. "Nothing belongs to the opposite worlds. "
