WARNING: This book contains a lot of personal theories about space, time and matter, and doesn't bother to highlight for the reader what is established physics and what is not. Parts of it flatly contradict what modern theoretical and experimental physics have discovered.

In addition, a lot of what is claimed here was written long before the recent important discoveries at the LHC, and has been rendered obsolete as a result.

If you'd like to learn actual physics, even at a basic level, I recommend getting a book by an actual physicist instead.

Format: Paperback
The ideas in this book on the much coveted The Theory of Everything are stunning. Duffield is the first to admit that there are some loose ends to his ideas, but the general theme is sound and he leads the reader into his ideas in an approachable way.

Duffield's chief inspiration is Einstein, whos papers, which he reads in the original german, say things that are startlingly different to what people usually say Einstein says. For example Einstein was opposed to the 4D "spacetime" geometric interpretation of Special and General Relativity.

The good

This is a no-nonsense physics book. Yet it is so interesting that a friend who is an archetypical spiritual woman (she borrowed a copy of this book from me) was hardly able to put it down. I doubt you could say that about dry physics books such as "The Brief History Of Time". Yet Relativity plus is far more insightful and entertaining than "Brief History Of Time", the latter being a book that I did not enjoy.

This is a cliche, but if you read the book you will never again, think of the world the same way. Because that is what the book is about. What is energy? What is light? What is charge? What is matter? What is gravity? What is an electron? What is a quark? The answers are not what you are expecting, believe me! The description of the electron and the photon alone are so poetic you will be astonished.

The quirks:

The book is not perfect. For the most part, the book is clear and lucid to the intelligent layman who knows nothing about physics. But new readers should not have a qualm about skipping some paragraphs that discuss some dense aspects of electromagnetism. This book is not dumbed down, which is great.

Have you ever wanted to know what's all those quantum physics, relativity, string theories, black holes, quarks, gravity, electricity, magnetism, photons and electrons, matter and anti-matter is all about and how it all "hangs" together? Or perhaps you are a deeply philosophical and contemplative type, often staring at the stars, feeling a strange closeness and reckoning and wondering what it is all about and how it all came about?

Relativity+ manages to cover all of those subjects, plus many more, in mere 181 pages written in plain English, with remaining 40 pages taken up by References. That's not bad. For a regular busy person who can spare no more than 10-15 minutes a day for quality reading and pondering about Life and Universe to finally have a consistent mental picture of her/his world and beyond - that's a pretty attractive proposition.

And so it should be. Less is more, whole is greater than the sum of its parts and John Duffield's book definitely delivers in both of those areas. It offers clarity, simplicity and, above all, coherent view of all that is - light and energy, our bodies, space and time, black holes, galaxies and Universe as a whole. And it will all feel close to your heart, relevant to you, homely - rather than some abstract, complex scientific mambo-jumbo full of imaginary, non-existent mathematical plains and dimensions that leave one even more clueless and wondering about the whole purpose of science instead.

Be warned though! This book might leave you hungry for more! Luckily John leaves plenty of reference points on the way: names, terms, concepts, theories and equations so you can drill deep down into them at your own will and leisure - the book is worth having just for this alone.

Format: Paperback
Many may be surprised to learn that physics is in dire straits today. Why, when all the news is about wonderful advances in all areas? The answer is that very few scientists are truly thinking! Everyone is rushing ahead with grand announcements based on presently accepted conventional wisdom. However, what is rarely mentioned is that conventional thinking simply cannot explain many phenomena and some theories lauded to the public are, quite simply, wrong. Of course, whether theories are right or wrong matters little if the perpetrators are bringing in money; that is, research grants and these grants are almost always awarded to those who conform to the dictats of conventional wisdom.
Hence, this book - written by someone outside what might be termed the mainstream - comes as a true breath of fresh air! John Duffield has thought in depth about many of the fundamental issues of physics. In this book, he presents his answers in a language accessible to anyone - scientist and layman alike. However, I would urge each and every reader - and I hope there are many - to approach the text with a truly open mind. Are all the ideas presented correct? I don't know. Do I agree with the ideas presented? With some, but I still have to think carefully about others. Many of the fundamental ideas are radically different from what has gone before and it may be that John Duffield is ahead of his time. Who knows? Some ideas, though, are regurgitation of ideas that used to be taught at A-level and are still to be found in, for example, such books as 'Intermediate Mechanics' by D. Humphrey - a book that used to be a standard A-level text but is now far too advanced for sixth forms!
