In following links around I had frequently run into citations from Joseph P. Farrell's books, and when I encountered his Secrets of the Unified Field: The Philadelphia Experiment, The Nazi Bell, and the Discarded Theory, I was hoping that it was going to be looking at the science behind the effects that he refers to as "torsion" and Hoagland labels "hyperdimensional".
Unfortunately, with the exception of looking at some of the developments of Einstein's thought (the "Discarded Theory" of the sub-title was the Unified Field Theory), this book is very little about the science and was all about the "conspiracies", especially those that various researchers have "found" around "The Philadelphia Experiment". I wonder why the author didn't just write a book on that, as this book only runs about 1/8th of its length looking at the work of Einstein and related theorists at the start, then goes on and on about the Philadelphia Experiment, and finally gives a brief "conspiracy" over-view of the "Nazi Bell" project, a subject the author has written extensively on elsewhere, but barely gives enough info on here to provide the reader a clue to what it was or was supposed to do, let alone how it was supposed to do it!
Now, I don't want to specifically say that I wasn't particularly interested in the Philadelphia Experiment, but it's one of those things that has rumors WAY out of control around it, and is one of those military projects that one is not likely to ever get a straight answer on one way or the other. I was, however, very interested in the possibility of delving into the science behind these various "secret projects". Regrettably, this was not much in evidence here, making the whole story another web of suggestive paper trails and fantastic stories of accidentally time-traveling bystanders.
Obviously, if the more extreme effects reported about the "Philadelphia Experiment" and the "Nazi Bell" could be proven true, the science made repeatable, and the whole process harnessed to some functional goal, this would be reality-changing, but sixty years later there's no sign of any technology that would seem to be rooted in these systems, which makes me think that it's all chasing rumors and creating conspiracies to explain why there's no straight answers.
Of course, if one approached this sort of material looking for an emotional charge from the "woo woo" conspiracy stuff, this book would be right up your alley ... but if you're looking for a cogent walk-through of the science related to these subjects, like I was, you're likely to be sorely disappointed.
What's almost as irritating is that I actually paid "retail" (well, Amazon's 32%-off price) for this, and I can't give you an alternative (the cheapest used copy there is almost the same price). Again, if you're looking for "oooh, big military/government conspiracy!" twaddle, you'll love this, otherwise save your money.
