In mathematics, the associative property is a property of some binary operations. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.
An operational amplifier is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. In this configuration, an op-amp produces an output potential that is typically hundreds of thousands of times larger than the potential difference between its input terminals. Operational amplifiers had their origins in analog computers, where they were used to perform mathematical operations in many linear, non-linear, and frequency-dependent circuits.
In statistics, the standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values. A low standard deviation indicates that the data points tend to be close to the mean of the set, while a high standard deviation indicates that the data points are spread out over a wider range of values.
An electric field is a vector field surrounding an electric charge that exerts force on other charges, attracting or repelling them. Mathematically the electric field is a vector field that associates to each point in space the force, called the Coulomb force, that would be experienced per unit of charge by an infinitesimal test charge at that point. The units of the electric field in the SI system are newtons per coulomb (N/C), or volts per meter (V/m). Electric fields are created by electric charges, or by time-varying magnetic fields. Electric fields are important in many areas of physics, and are exploited practically in electrical technology. On an atomic scale, the electric field is responsible for the attractive force between the atomic nucleus and electrons that holds atoms together, and the forces between atoms that cause chemical bonding. Electric fields and magnetic fields are both manifestations of the electromagnetic force, one of the four fundamental forces of nature.
Division is one of the four basic operations of arithmetic, the others being addition, subtraction, and multiplication.

The Dead Sea Scrolls are ancient Jewish religious, mostly Hebrew, manuscripts found in the Qumran Caves in the West Bank near the Dead Sea. Scholarly consensus dates these scrolls from the last three centuries BCE and the first century CE. The texts have great historical, religious, and linguistic significance because they include the second-oldest known surviving manuscripts of works later included in the Hebrew Bible canon, along with deuterocanonical and extra-biblical manuscripts which preserve evidence of the diversity of religious thought in late Second Temple Judaism. Almost all of the Dead Sea Scrolls collection is currently under the ownership of the Government of the state of Israel, and housed in the Shrine of the Book on the grounds of the Israel Museum.
In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6:8 and the ratio of oranges to the total amount of fruit is 8:14.
Capacitance is the ratio of the change in an electric charge in a system to the corresponding change in its electric potential. There are two closely related notions of capacitance: self capacitance and mutual capacitance. Any object that can be electrically charged exhibits self capacitance. A material with a large self capacitance holds more electric charge at a given voltage than one with low capacitance. The notion of mutual capacitance is particularly important for understanding the operations of the capacitor, one of the three elementary linear electronic components.
The Order of Saint Vladimir was an Imperial Russian Order established in 1782 by Empress Catherine II in memory of the deeds of Saint Vladimir, the Grand Prince and the Baptizer of the Kievan Rus'.
The Order of Saint George is today the highest purely military decoration of the Russian Federation. Originally established November 26, 1769 as the highest military decoration of the Russian Empire by Empress Catherine the Great. After the 1917 Russian Revolution it was awarded by the White movement anti-communist forces under Alexander Kolchak until their collapse in 1921. The order was revived in the Russian Federation on August 8, 2000 by Decree №1463 of the President of Russia. The current award criteria were amended on September 7, 2010 by Presidential Decree 1099.
Kamaal Ibn John Fareed, better known by his stage name Q-Tip, is an American rapper, record producer, singer, actor and DJ. Nicknamed The Abstract, he is noted for his innovative jazz-influenced style of hip hop production and his philosophical, esoteric and introspective lyrical themes. He embarked on his music career in the late 1980s, as an MC and main producer of the influential alternative hip hop group A Tribe Called Quest. In the mid-1990s, he co-founded the production team The Ummah, followed by the release of his gold-certified solo debut Amplified in 1999. In the 2000s, he released the Grammy Award-nominated album The Renaissance and the experimental album Kamaal the Abstract.
Q1 is a 322.5-metre (1,058 ft) skyscraper in Surfers Paradise, Queensland, Australia. The residential tower on the Gold Coast lost its title as the world's tallest residential building to the 337-metre (1,106 ft) The Marina Torch in Dubai on 29 April 2011. It is now the sixth-tallest residential tower in the world and is the tallest building in Australia and the Southern Hemisphere, and the second-tallest free-standing structure in the Southern Hemisphere, behind the Sky Tower in Auckland, New Zealand. The Q1 officially opened in November 2005.
The DHC-8 Dash 8 is a series of turboprop-powered regional airliners, introduced by de Havilland Canada (DHC) in 1984. DHC was later bought by Boeing in 1988, then by Bombardier in 1992; the program is to be resold to Viking Air parent Longview Aviation Capital by late 2019. Powered by two Pratt & Whitney Canada PW100s, it was developed from the Dash 7 with improved cruise performance, lowered operational costs but worse STOL performance. Three sizes were offered: initially the 37-40 seat -100 until 2005 and the more powerful -200 from 1995, the stretched 50-56 seats -300 from 1989, both until 2009, and the 68-90 seats -400 from 1999, still in production. The Q Series are post-1997 variants with quieter cabins.
Thomism is the philosophical school that arose as a legacy of the work and thought of Thomas Aquinas (1225–1274), philosopher, theologian, and Doctor of the Church. In philosophy, Aquinas' disputed questions and commentaries on Aristotle are perhaps his most well-known works. In theology, his Summa Theologica is one of the most influential documents in medieval theology and continues to be the central point of reference for the philosophy and theology of the Catholic Church. In the 1914 encyclical Doctoris Angelici Pope Pius X cautioned that the teachings of the Church cannot be understood without the basic philosophical underpinnings of Aquinas' major theses:
The capital theses in the philosophy of St. Thomas are not to be placed in the category of opinions capable of being debated one way or another, but are to be considered as the foundations upon which the whole science of natural and divine things is based; if such principles are once removed or in any way impaired, it must necessarily follow that students of the sacred sciences will ultimately fail to perceive so much as the meaning of the words in which the dogmas of divine revelation are proposed by the magistracy of the Church.
Chromosome 17 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 17 spans more than 83 million base pairs and represents between 2.5 and 3% of the total DNA in cells.
