And Now This: Quasicrystals With Forbidden Symmetries
« on: March 18, 2015, 06:09:41 PM »
Second natural quasicrystal found in ancient meteorite

A team from Princeton University and the University of Florence in Italy has discovered a quasicrystal -- so named because of its unorthodox arrangement of atoms -- in a 4.5-billion-year-old meteorite from a remote region of northeastern Russia, bringing to two the number of natural quasicrystals ever discovered. Prior to the team finding the first natural quasicrystal in 2009, researchers thought that the structures were too fragile and energetically unstable to be formed by natural processes.

"The finding of a second naturally occurring quasicrystal confirms that these materials can form in nature and are stable over cosmic time scales," said Paul Steinhardt...

The most captivating mental image for me in Lovecraft was where the sailor got trapped crossing what appeared to be an obtuse angled surface that was actually acute, stuck and perhaps crushed to death in this invisible chasm, in the non Euclidean metropolis, or necropolis, of R'lyeh.

However the Starry Wisdom Cult and the Esoteric Order of Dagnon with its unusual clerical vestments were of much interest in the realm of comparative theology.  Although his mentioning of the Yazidis was uninformed and came across as a theological cheap shot, although there is evidence to suggest that in the past some Yazidis were genuinely afraid of Taus Melek, adding credence to the whole Decil Worship thing.

But these crystals aren't quite as non Euclidean as what Lovecraft had in mind I fear.  Although I suspect they would freak him out anyway, poor guy.

I am Oriental Orthodox but love the Eastern Orthodox, and the Byzantine liturgy.  I also love the Western liturgy.  I hope for the reconciliation of our churches.

Please forgive any offense my posts cause; none is intended. No statements I make should be regarded as authoritative, regardless of tone. Let us bless the Lord ar all times.

Seems like it is always Russia that gets the interesting meteorites.  I'm jealous. :-X
