Henrik Petersson
Henrik Petersson (pronounced in Swedish as [hɛnːrɪk peːtɛrsɔn]), born in Uppsala, Sweden, on April 6 1973, is a Swedish mathematician, high school mathematics teacher, and writer. Petersson is an associate professor at Chalmers University of Technology and works as a docent in mathematics at Hvitfeldtska high school, in Gothenburg.
Biography
Born in 1973 in Uppsala, Henrik Petersson displayed an early aptitude for sports, primarily cross-country skiing and running, in which he achieved several prizes. He notably ran the fastest time among 14-year-old teenagers in the Lidingö 10-kilometer race (34.50, 1987), and his current half-marathon record is 1 hour, 7 minutes, and 12 seconds (at Borås, 1994). He was also the district champion in Uppland in 1983 and 1985, as well as the champion of Småland in 1986, 1987, and 1989. [1] It was not until his university years that he discovered his passion for mathematics. [2]
In 2001, he obtained his PhD in mathematics and began working at Chalmers, where he published 12 articles discussing various scientific areas between 2005 and 2008. His work at the university primarily concerned linear dynamical systems and theory of operation, with theoretical applications on functions. [3]
Petersson began his teaching career in 2010 at Hvitfeldtska. [4] He is perhaps best known for his book, Problemlösningens grunder (2013), which he actively uses in his teaching. [5]
In 2019, he published two books, Avancera I and Avancera II, intended as an alternative to current high school mathematics textbooks. They differ in style, being closer to university-level texts, and emphasize problem-solving. [6]
Works as a teacher
Petersson teaches mathematical problem-solving classes at Hvitfeldtska for the advanced mathematics students, where he is the lead teacher. [2][5] The class aims to challenge students with an interest and talent in mathematics, aiming for improvement beyond what's achievable within the standard Swedish school system.[2]
His teaching methods have helped numerous students qualify for national and international mathematics competitions, including the Swedish selection process for the International Mathematics Olympiad. [7][8] Four of his students qualified for the finals in 2019.[9]
He also runs an online platform, [1], for high school students interested in exploring mathematics beyond the classroom curriculum. The platform features various "modules" on different mathematical topics and is funded by the Solstickan foundation. [10][11] [12]
