I’ve got a back catalogue of more than 30 physics textbooks for all secondary school ages. Mostly, these have been published by Pearson, including A Level Physics books for Edexcel exam board courses, both the UK and International A Level courses. However, I’ve also written a number of the BBC Bitesize webpages for GCSE Physics, and a variety of materials for Oxford University Press, and Swedish publisher Kognity, as well as teachers’ guides for the Egyptian science curriculum via York Press.
