'I Have Been Happy from the First Moment'
Takashi Takebe is a Research Fellow at the International Laboratory of Representation Theory and Mathematical Physics and Professor at the Faculty of Mathematics. He has been at HSE since 2009. He is a PhD in Mathematics from the University of Tokyo. He spoke to HSE News in English service about the unpredictability of life for international academics in Moscow, about teaching mathematics to Russians, the problems of language and cycling tours.
