I get this small intelligent book as Christmas present from Kari Hag. It is about the first woman in Norway who took a PhD in Mathematics, 79 years before our Idun Reiten. Well written book.  I enjoyed very much the part about life (the studies in Zurich, the time in Ås) and family (she was fond of her family and she was engaged three times, one with a student). I must admit I did not try to understand the Mathematic, it should be possible as I have passed Math 1 and Math 2 from University of Pisa with decent grades in the 80’s, but I would need more time. Thanks @Kari, you rule.
