Bruce Cathie, an ex-airline pilot from New Zealand, started his grid research whilst plotting sitings of UFO's back in the fifties.
A link to his site is provided in the list to the right.
Going through his site recently, I came across his work on the magnetic fields of the Earth.
I hadn't noticed a Phi correlation previously, but did this time:
According to Cathie there are two magnetic fields which combine, or counter-act the other.
The two fields are given he gives the figures for combined field strength and their diffeence.
Field A 1850.900532 lines of force per square centimetre, or as he prefers, 12245.6998per square geographic inh.
Field B 1257.139035 per square cm, or 8317.32698 per square geo-inch.
Combined, that is (A+B) = 20574.234 per square geo-inch.
Difference, that is (A-B) = 3928.371 per square geo-inch.
(A+B)/(A-B) = 5.237344945.
which; divided by 2 = 2.618672493, which is close to Phi-squared.
The square root is 1.618231279, of which Phi (1.618034) is 99.9878%.
One in ten thousand is a very good correlation! At this point I do not know what this could signify, just noting in the passing!
