Ancient Mysteries, Modern Visions: The Magnetic Life of Agriculture Paperback – January 1, 2001

many knowledge

The author treads on a, at first glance, esoteric path, but I must admit his points and thoughts are well presented. He brings forth evidence that is hard to deny.The key idea that rocks, earth and soil are subject to low intensity electromagnetic fields lies on solid ground. Philip Callahan makes a very credible case that rocks have paramagnetic characteristics, i.e. can produce / resonate / amplify low intensity magnetic fields.Did ancient cultures knew about ways to optimize their crop yields by choosing appropriate designs and materials for stone buildings? This hypothesis deserves to be taken very seriously. Thank you to the author for presenting his views and scientific studies on this fascinating topic.

Good

Author has variety of knowledge that seems to be unrelated until he explains how he spent a life time putting this puzzle together. Very unique concepts that deserve much more research. If you have an understanding of electrical energy as used especially in radio waves this will add a new dimension to how it serves a different purpose than that of man made uses.

I learned soooo much...such amazing information

Got it...

A few short years ago we (all scientists) "knew" that the universe began in a "big bang". Now many reputable cosmologists say there was no "bang". We also knew there was no such thing as negative energy, dark matter, dark energy and we "knew" above all that there were only 3 dimensions (plus time). All of these things are now known to exist. The best theories (the ones that correctly predict the most observations) now say there are 11 dimensions (recently upgraded from 10). Do we really "know" that magnetic fields have no effect on plants? We do know that many animals (including humans) respond to magnetic fields. I don't believe in "gurus" and I'm a practical "show me" scientist. And I say "not so fast, let's hear the man out". After all the book is cheap and lateral thinking often bears rich fruit; at least it has for me.

Book was in fine shape.

I liked reading Phil Callahan's book, bvut there is a lot of repetition from his other books.
