The book does indeed go into the maths a lot more, the series was quite enjoyable but glossed over a key part of the book, which took endless attempts in the game to why the Sun behaved a certain way( until it was realised finally there was more than one). Half the book had you wondering why there were stable eras and chaotic eras and if there was a reason for it at all.
