Anna Cox has spent over 25 years in the classroom years as a physics and mathematics educator at various levels: secondary school, university foundation school, and college of education. She has produced numerous physics and mathematics resources including textbooks, workbooks and on-line learning modules. Currently, as well as raising her family, she spends her summers surfing, winters skiing and runs all year round. Dr Chris Smaill enjoyed teaching high-school physics and mathematics for 27 years, most recently as Head of Physics at Rangitoto College, New Zealand's largest secondary school. During this time he set and marked national examinations, and trained high-school teachers. He also lectured for 14 years in the Faculty of Engineering at the University of Auckland. His physics textbooks have been successfully published for more than 30 years. Currently, he finds retirement affords him more time for family, reading, on- and off-road cycling, and adventure travel.
