The chapters are very readable and immediately accessible - the starting standard is very gentle. There are a lot of every day examples which allow the material to be linked to familiar phenomena. I felt all of the material I would expect to be there was included, with not too much superfluous. The maths was sufficient to understand the material, define the important parameters and introduce the necessary equations but was explained well enough and at a simple enough level to allow those without A level maths and just starting University level maths to access the material.
