Sci. (2007) 1106. and. Instead, they were arranged in a variety of different configurations, which should be impossible in a natural substance based on our understanding of the science. P.J. Pieces of the Khatyrka meteorite are being studied by other teams of scientists, for other purposes, as well. Lincei. Phys. Lett. Am. He added that he believes in two sets of “impossible” discoveries: ones which violate the laws of physics, and ones which undercut scientists’ long-held assumptions. He co-founded the prestigious Princeton Center for Theoretical Science and served as its Director from 2007 to 2019. Science 324 (2009) 1306, The discovery of the first natural quasicrystal, Icosahedrite, Al63Cu24Fe13, the first natural quasicrystal
Another critical clue that the quasicrystal wasn’t from here is the fact that the ratio of oxygen isotopes found in the mineral aren’t consistent with any similar ratio found on Earth. So as far as Steinhardt was concerned, there was only one thing he could do. PNAS 109 (2012) 1396, First evidence that natural quasicrystals are extraterrestrials – remnants of a meteorite, The discovery of the first natural quasicrystal: A new era for mineralogy?
Phys. The references below describes the evidence that Islamic artisans constructed quasicrystals tilings hundreds of years before Roger Penrose invented his famous tilings and before the concept of quasicrystals was even formulated.
The 2012 Van Winter Memorial Lecture: Paul Steinhardt and Quasicrystals March 5, 2012 Each year, the Department of Mathematics and the Department of Physics and Astronomy jointly organize the Van Winter Memorial Lecture, which brings in distinguished speakers to give lectures on matters of common interest to mathematicians and physicists. --- Sir Roger Penrose, author of The Emperor’s New Mind. What are Quasicrystals? Hollister, et al., " Impact-induced shock and the formation of natural quasicrystals in the early solar system , ” Nature Communications 5 , 4040 (2014). Impossible was also the word used by scientific heavyweights including Richard Feynman and Linus Pauling to describe Steinhardt’s quest to develop a scientific theory of quasicrystal formation, and to find naturally occurring examples of the material (Shechtman’s samples had been synthesized in the lab).
