I picked up this book because Rodney Brooks bragged on Quora, the Q&A website of much greater legitimacy than low-brow Reddit, that Quantum Field Theory (QFT) was, in fact, easy to understand, "just read my book". Also, he said, AFT could be presented without any mathematical explanation and he did that in his book for the most part.
This is just preliminary review, since I haven't finished the book (and may never).
Briefly, Brooks thinks that by spraying little circles of various colored inks on the page to represent the various fields, for instance, gravity field, blue, electromagnetic, green, and so on that this will lead to a greater understanding of QFT. Well, it doesn't for me.
He says a field is a "property or condition of space". That's it. He then goes on in the book by implying fields are real. But they are not. They are a mental concept just like spacetime.
First we must define "space". The dictionary has numerous definitions but I will pick the ones I think are relevant to the cosmos and the world of the very tiny.

1. An empty area (usually bounded in some way between things)
2. Any location outside the Earth's atmosphere

Thus, to say a property or condition of space is to say a field is a property of something that is empty. Right away, there is a contradiction, hence, a field is a mental concept only.
The book is essentially a history of relativity and quantum theory since no mathematics are involved. The style of the book is very annoying to me. Extensive quotes are generally indented and in smaller type face but Brooks has quotes in bold face which, in my way of thinking, means emphasis. In this book, they are not.
Also, very annoying for me is the use of common nouns for objects in our Solar System such as "the earth", "the moon", and "the sun". This is an error of British English lasting for 100s of years. To see how ridiculous this usage is imagine if we said "the venus", "the jupiter".
Those objects in our Solar System have proper noun names: Earth, Luna, and Sol.
More on this book if I finish it. ( )
