Due to a sudden, unexpected passing in the family a few years ago and another more recently and my subsequent (mental) health issues stemming from that, I was unable to download this book in time to review it before it was archived as I did not visit this site for several years after the bereavements. This meant I didn't read or venture onto netgalley for years as not only did it remind me of that person as they shared my passion for reading, but I also struggled to maintain interest in anything due to overwhelming depression. I was therefore unable to download this title in time and so I couldn't give a review as it wasn't successfully acquired before it was archived. The second issue that has happened with some of my other books is that I had them downloaded to one particular device and said device is now defunct, so I have no access to those books anymore, sadly.

This means I can't leave an accurate reflection of my feelings towards the book as I am unable to read it now and so I am leaving a message of explanation instead. I am now back to reading and reviewing full time as once considerable time had passed I have found that books have been helping me significantly in terms of my mindset and mental health - this was after having no interest in anything for quite a number of years after the passings. Anything requested and approved will be read and a review written and posted to Amazon (where I am a Hall of Famer & Top Reviewer), Goodreads (where I have several thousand friends and the same amount who follow my reviews) and Waterstones (or Barnes & Noble if the publisher is American based). Thank you for the opportunity and apologies for the inconvenience.

Not for the lay person. Gravitomagnetism is part history, part deep dive into the hard science behind the search for the ultimate understanding and control of gravity. Mathematical equations intertwine with historical accounts of past theories and experiments. This book, by admission, is the author's attempt to prompt other scientists in the field of physics to undertake and expand on some of the theories and experiments done in the past. It is hard going for the lay person or casual reader interested in the highlights of the theory of gravity and the cutting edge attempts to control it. If you have a very solid understanding of physics, you may find something that expands your knowledge. If you are only trying to explore the concepts instead of reading about the mathematics, this may be too daunting.

A very readable (and helpfully illustrated), explanatory introduction to "Gravity's Secret," the magnetic component of gravity. The author believes this comprehension may eventually result in gravity control (not to be confused with, " anti-gravity.")
