Roger holds a Ph.D at the University of Oslo in 2008. The thesis has already demonstrated clear perfection, also in aesthetic aspects and the desire to present the content as best as possible. After earning his PhD, he changed his focus to spreading the joy of mathematical discoveries and patterns to a wider audience. As a lecturer, he aroused enthusiasm for the subject of logic in thousands of students. In his zeal for continuous improvement, he filmed his lectures and created an online version of his course several years before the pandemic forced the rest of us to follow suit.

Roger Antonsen was very active which disseminates popular science through hundreds of lectures in Norway and abroad, newspaper columns, books, art projects, web series and creative festivals. He imparted logic and mathematics through juggling, shoelaces, card shuffling, the Rubik's Cube, and much more. He captivated the audience with his infectious commitment and aesthetically pleasing, perfectly choreographed presentations. TEDTalks on mathematics and understanding have millions of views. He is also known as the author of the Magiske Mønstre column in Aftenposten and through his contributions to the program “Abel's tower” on NRK radio.
