I have been now teaching for 36 years at university, college and secondary school levels. I began my secondary school teaching in 1989 when I took a post as a science teacher in Hamilton, Canada. After six years of teaching in Canada, I decided to travel to Europe by accepting a post at an international school in Munich, Germany. This marked the beginning of 25 years of international education and my involvement with the IB programme, teaching IB Physics, Mathematics and TOK for the past 25 years. I also had a fantastic opportunity of teaching physics and mathematics at Oxford and Cambridge Universities as well as MIT, and I have tried to continue conducting academic research in thermodynamics when time permits. I have been an IB inspector, examiner and workshop leader and I have written a Pre-IB Mathematics book. My passion of film, history and ….cats almost matches my love of physics and mathematics. I have two grown-up children living now in Vancouver and Auckland respectively. This year marks twelve years of my work at TBS and my return to Poland after almost 30 years of absence.
