This neat "rock" is actually made out of a type quasiperiodic crystal (or quasicrystal). A quasicrystal is very interesting in that it has a pattern
that periodically repeats but is subject to some form of unpredictability. Also, it has the ability to fill a space endlessly and will produce as if
it were a fractal. However, quasicrystals actually lack translation symmetry and so they will not, at some point, re-create their original pattern (in
any direction). This is due to the fact that normal crystals can only posses a rotation-symmetry of two, three, four, and six-fold. Where as
quasicrystals can contain odd-numbered symmetries like five-fold rotation.
Originally the concept of such crystals was created in mathematics being called "Aperiodic tilings" in the 1960s. Then, eventually, the quasicrystals
were created in a laboratory. The crystals themselves are also different from normal crystals in that they contain an arrangement of atoms that is
based off an irrational number such as: the square root of 2:1, as opposed to normal crystals that go off a rational number. (This is stated in the
Originally they were strictly synthetic. However, in 2007, a rock containing quasicrystals was eventually found in nature and it created a paradigm
shift in the field of crystallography.
After two years of research they have concluded that this rock is of an extraterrestrial origin
The reason I find this so fascinating is that, what scientists and mathematicians originally thought was man-made and unique had already been in
existence in space, and not for just a short period of time either. The article claims that "quasicrystals are one of the first minerals to have
formed in the solar system — in the top 250 — long before most of the common minerals found on Earth."
Are we really as creative as we believe?
