Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium or sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor. Emerald is a cyclosilicate.
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.
Anna Ioannovna, also russified as Anna Ivanovna and sometimes anglicized as Anne, served as regent of the duchy of Courland from 1711 until 1730 and then ruled as Empress of Russia from 1730 to 1740. Much of her administration was defined or heavily influenced by actions set in motion by her uncle, Peter the Great, such as the lavish building projects in St. Petersburg, funding the Russian Academy of Science, and measures which generally favored the nobility, such as the repeal of a primogeniture law in 1730. In the West, Anna's reign was traditionally viewed as a continuation of the transition from the old Muscovy ways to the European court envisioned by Peter the Great. Within Russia, Anna's reign is often referred to as a "dark era".
Harry Martinson was a Swedish writer, poet and former sailor. In 1949 he was elected into the Swedish Academy. He was awarded a joint Nobel Prize in Literature in 1974 together with fellow Swede Eyvind Johnson "for writings that catch the dewdrop and reflect the cosmos". The choice was controversial, as both Martinson and Johnson were members of the academy.
Spontaneous order, also named self-organization in the hard sciences, is the spontaneous emergence of order out of seeming chaos. The term "self-organization" is more often used for physical changes and biological processes, while "spontaneous order" is typically used to describe the emergence of various kinds of social orders in human social networks from the behavior of a combination of self-interested individuals who are not intentionally trying to create order through planning. Proposed examples of systems which evolved through spontaneous order or self-organization include the evolution of life on Earth, language, crystal structure, the Internet, and a free market economy.
Tairus is a synthetic gemstone manufacturer. It was formed in 1989 as part of Mikhail Gorbachev's perestroika initiative to establish a joint venture between the Russian Academy of Sciences and Tairus Created Gems Co Ltd. of Bangkok, Thailand. Today Tairus is a major supplier of hydrothermally grown gemstones to the jewellery industry. Later, Tairus became a privately held enterprise, operating out of its Bangkok distribution hub under the trade name Tairus, owned by Tairus Created Gems Co Ltd. of Bangkok, Thailand.
Barium titanate (BTO) is an inorganic compound with chemical formula BaTiO3. Barium titanate appears white as a powder and is transparent when prepared as large crystals. It is a ferroelectric, pyroelectric, and piezoelectric ceramic material that exhibits the photorefractive effect. It is used in capacitors, electromechanical transducers and nonlinear optics.
John Werner Cahn was an American scientist and recipient of the 1998 National Medal of Science. Born in Cologne, Weimar Germany, he was a professor in the department of metallurgy at the Massachusetts Institute of Technology (MIT) from 1964 to 1978. From 1977, he held a position at the National Institute of Standards and Technology. Cahn had a profound influence on the course of materials research during his career. One of the foremost authorities on thermodynamics, Cahn applied the basic laws of thermodynamics to describe and predict a wide range of physical phenomena.

He has served as editor for the following scholarly journals: IEEE Transactions on Engineering Management, the Journal of Applied Management Studies, the Journal of Information Technology Management, the Journal of Management Systems, and the Communications of the ACM.
Sergey Alexandrovich Martinson was a Russian eccentric comic actor, the master of pantomime, buffoonery and grotesque. He became People's Artist of the RSFSR in 1964.
Aleksandr Lazarevich Lokshin (1920–1987) was a Soviet composer of classical music. He was born on 19 September 1920 in the town of Biysk, in the Altai Region, Western Siberia, and died in Moscow on 11 June 1987.
Hydrothermal synthesis includes the various techniques of crystallizing substances from high-temperature aqueous solutions at high vapor pressures; also termed "hydrothermal method". The term "hydrothermal" is of geologic origin. Geochemists and mineralogists have studied hydrothermal phase equilibria since the beginning of the twentieth century. George W. Morey at the Carnegie Institution and later, Percy W. Bridgman at Harvard University did much of the work to lay the foundations necessary to containment of reactive media in the temperature and pressure range where most of the hydrothermal work is conducted.
The Concert Fantasia in G, Op. 56, for piano and orchestra, was written by Pyotr Ilyich Tchaikovsky between June and October 1884. It was premiered in Moscow on 6 March [O.S. 22 February] 1885, with Sergei Taneyev as soloist and Max Erdmannsdörfer conducting. The Concert Fantasia received many performances in the first 20 years of its existence. It then disappeared from the repertoire and lay virtually unperformed for many years, but underwent a revival in the latter part of the 20th century.
Ivan Yevstafyevich Khandoshkin was a Russian Empire violinist and composer of Ukrainian Cossack origin. He has been described as "the finest Russian violinist of the eighteenth century".
Rudolf Borisovich Barshai was a Soviet and Russian conductor and violist.

Patricia Martin Dove is an American geochemist. She is a University Distinguished Professor and the C.P. Miles Professor of Science at Virginia Tech with appointments in the Department of Geosciences and Department of Chemistry. Her research focuses on the kinetics and thermodynamics of mineral reactions with aqueous solutions in biogeochemical systems. Much of her work is on crystal nucleation and growth during biomineralization and biomaterial synthesis. She was elected a member of the National Academy of Sciences (NAS) in 2012 and currently serves as chair of Class I, Physical and Mathematical Sciences.

Alexei Vasilievich Shubnikov was a Russian crystallographer and mathematician. Shubnikov was the founding director of the Institute of Crystallography of the Academy of Sciences of the Soviet Union in Moscow. Shubnikov pioneered Russian crystallography and its application.
The 1974 Nobel Prize in Literature was awarded jointly to Swedish authors Eyvind Johnson (1900–1976) "for a narrative art, farseeing in lands and ages, in the service of freedom" and Harry Martinson (1904–1978) "for writings that catch the dewdrop and reflect the cosmos." The winners were announced in October 1974 by Karl Ragnar Gierow, permanent secretary of the Swedish Academy, and later sparked heavy criticisms from the literary world.
