I just saw this news item about a company that can detect metals under water and underground.
Here’s a short snippet from a CNN story: (I tried to post a link but I haven't made 15 posts yet... you can find it if you Google "CNN GeoResonance")
> According to an Australian newspaper account, GeoResonance makes use of former Soviet defense technology that has since been demilitarized.
> It analyzes super-weak electromagnetic fields captured by airborne multispectral images.
> "And what we do is we look at the nuclei of an atom, copper or nickel or iron. And so we knew we had the tools to search for the plane," Pope said.
I don’t know how multispectral images are supposed to distinguish between nuclei or how the signals make it through water or soil. I thought that this was the domain of magnetic resonance imaging, nuclear quadrupole resonance or some really high energy particles/photons.
Any ideas of what physics they can be leveraging here? Or is this just some high tech form of dowsing?
