This book is a good attempt to put a quart into a pint pot.
Each chapter covers a topic, such as: optics, mechanics, "energy fields and forces", "Into the Atom" and "Space-time continuing" and within each chapter there is an 'easy going read' to be had with information about the people, what they did and a little bit of explanation of what their work meant to the advancement of Physics. (You do need to have some science knowledge to get the best value, but then, it is a good book to see what part of Physics you don't know!)
Some mentioned were caught up with their country's politics, like the French Revolution, and we learn how their advancement was helped or hindered by it: some had untimely an death because of their political choices! Others died as a result of their experiments.
There are many smallish diagrams, text inserts and pictures that do not overpower the book but help to highlight particular points.
I would think that most 'Science aware' people would find this book worth reading, while A'level Physics and Chemistry students would find it fills the holes that their A'level courses cannot fill because science A'levels are (hopefully!) about science and not so much about history or politics.
It may also be a good book to read to see if you want to take Physics A'level. A good addition for a school library.
