I usually enjoy reading Maths books. I like to see what else Maths is used for, beyond what I know and beyond my own work. It is interesting to see how maths can be used across fields and that sometimes leads me to wonder as well on other techniques that I could try for my work. More importantly I like to see how someone else communicates these ideas, as that as well is an important part of my work. But most of it, I just find it fun and relaxing to read about maths (especially if it is not a text book full of formulas only). I started this book during a period that I was busy at work, and thinking that these topics would be interesting enough for me to read a bit and get my mind of work.
Unfortunately I did not enjoy the book at all. Although a text in the back of the book states that Hugh Barker is an author and editor, this book is in desperate need of both or at the very least an editor and proof reader. It is still interesting to see how maths is applied across different fields, and how new technology and progress in general is driven by maths. But the book is largely just a collection of maths topics that are somewhat related within the chapter. Basically the author crammed as much maths topics and facts in as he could, with some info being unnecessary and a distraction and without a clear link between topics. In some cases though the author could have linked the topics better, in others I don't see the link. In an early chapter, a problem is mentioned without it being clarified and then in the next sections references are made to how the new bits of maths relate to the problem. This was very tiring and annoying as the problem is not explained and therefore the connection is largely based on the authors word.
I also did not appreciate the climate change chapter being called blah, blah, blah. I understand that this is a reference to the Greta Thunberg quote mentioned in the chapter but it's a bit thin and it makes it seem like the author does not care for the topic (which does not appear the case from the writing)
The book also contains some mistakes, at least three that I spotted.
- a graph showing the logic 'OR' function is explained by referencing 'the line in the graph', when it has two lines. Presumably this is the 'XOR' function not the 'OR function'
- Bayes' formula re-uses the P(A|B) that is being estimated in the numerator of the formula, which should have been P(A).
- for compressing code an example is given, where the notation denotes (x,y) with x being the starting location of a text and y being the length. For the last line of the encoded text the book says (41,73) but using a length of 73 does not make sense. In this case the 73 is the end of the line being referenced, so the encoding has to be (41,33).
So would not recommend this book. It is not clear and simple enough for people with little or no understanding of maths, and there is not enough depth for anyone that is interested to understand more. At best it wets the appetite for further research.
