In mathematics and physics, the Poincaré recurrence theorem states that certain dynamical systems will, after a sufficiently long but finite time, return to a state arbitrarily close to (for continuous state systems), or exactly the same as (for discrete state systems), their initial state.

The Poincaré recurrence time is the length of time elapsed until the recurrence. This time may vary greatly depending on the exact initial state and required degree of closeness. The result applies to isolated mechanical systems subject to some constraints, e.g., all particles must be bound to a finite volume. The theorem is commonly discussed in the context of ergodic theory, dynamical systems and statistical mechanics. Systems to which the Poincaré recurrence theorem applies are called conservative systems.

The theorem is named after Henri Poincaré, who discussed it in 1890 and proved by Constantin Carathéodory using measure theory in 1919.

There was widespread support for animal welfare in Nazi Germany (German: Tierschutz im nationalsozialistischen Deutschland) among the country's leadership. Adolf Hitler and his top officials took a variety of measures to ensure animals were protected.

Several Nazis were environmentalists, and species protection and animal welfare were significant issues in the Nazi regime. Heinrich Himmler made an effort to ban the hunting of animals. Hermann Göring was a professed animal lover and conservationist, who, on instructions from Hitler, committed Germans who violated Nazi animal welfare laws to concentration camps. In his private diaries, Nazi Propaganda Minister Joseph Goebbels described Hitler as a vegetarian whose hatred of the Jewish religion in large part stemmed from the ethical distinction this faith drew between the value of humans and the value of other animals; Goebbels also mentions that Hitler planned to ban slaughterhouses in the German Reich following the conclusion of World War II. Nevertheless, animal testing was common in Nazi Germany.

The current animal welfare laws in Germany were initially introduced by the Nazis.

Theodore John Kaczynski (; born May 22, 1942), also known as the Unabomber (), is an American domestic terrorist, anarchist, and former mathematics professor. He was a mathematics prodigy, but he abandoned his academic career in 1969 to pursue a more primitive lifestyle. Between 1978 and 1995, he killed three people and injured 23 others in an attempt to start a revolution by conducting a nationwide bombing campaign targeting people involved with modern technology.

In 1971, Kaczynski moved to a remote cabin without electricity or running water near Lincoln, Montana, where he lived as a recluse while learning survival skills in an attempt to become self-sufficient. He witnessed the destruction of the wilderness surrounding his cabin and concluded that living in nature was untenable; he began his bombing campaign in 1978. In 1995, he sent a letter to The New York Times and promised to "desist from terrorism" if the Times or The Washington Post published his essay Industrial Society and Its Future, in which he argued that his bombings were extreme but necessary to attract attention to the erosion of human freedom and dignity by modern technologies that require large-scale organization.

Kaczynski was the subject of the longest and most expensive investigation in the history of the Federal Bureau of Investigation. Before his identity was known, the FBI used the case identifier UNABOM (University and Airline Bomber) to refer to his case, which resulted in the media naming him the "Unabomber." The FBI and Attorney General Janet Reno pushed for the publication of Industrial Society and Its Future, which led to a tip from Kaczynski's brother David, who recognized the writing style.

After his arrest in 1996, Kaczynski tried unsuccessfully to dismiss his court-appointed lawyers because they wanted him to plead insanity in order to avoid the death penalty, whereas he did not believe that he was insane. In 1998, a plea bargain was reached under which he pleaded guilty to all charges and was sentenced to life in prison without possibility of parole.

The Aramaic original New Testament theory is the belief that the Christian New Testament was originally written in Aramaic.

There are several versions of the New Testament in Aramaic languages:

1. the Vetus Syra (Old Syriac), a translation from Greek into early Classical Syriac, containing most—but not all—of the text of the 4 Gospels, and represented in the Curetonian Gospels and the Sinaitic Palimpsest
2. the Christian Palestinian Aramaic Lectionary fragments represented in such manuscripts as Codex Climaci Rescriptus, Codex Sinaiticus Rescriptus, and later lectionary codices (Vatican sir. 19 [A]; St Catherine’s Monastery B, C, D)
3. the Classical Syriac Peshitta, a rendering in Aramaic of the Hebrew (and some Aramaic, e.g. in Daniel and Ezra) Old Testament, plus the New Testament purportedly in its original Aramaic, and still the standard in most Syriac churches
4. the Harklean, a strictly literal translation by Thomas of Harqel into Classical Syriac from Greek
5. the Assyrian Modern Version, a new translation into Assyrian Neo-Aramaic from the Greek published in 1997 and mainly in use among Protestants
6. and a number of other scattered versions in various dialects

The traditional New Testament of the Peshitta has 22 books, lacking the Second Epistle of John, the Third Epistle of John, the Second Epistle of Peter, the Epistle of Jude and the Book of Revelation, which are books of the Antilegomena. Closure of the Church of the East's New Testament Canon occurred before the 'Western Five' books could be incorporated. Its Gospels text also lacks the verses known as Jesus and the woman taken in adultery (John 7:53–8:11) and Luke 22:17–18, but does have the 'long ending of Mark.'

Commonplace books (or commonplaces) are a way to compile knowledge, usually by writing information into books. They have been kept from antiquity, and were kept particularly during the Renaissance and in the nineteenth century. Such books are essentially scrapbooks filled with items of every kind: recipes, quotes, letters, poems, tables of weights and measures, proverbs, prayers, legal formulas. Commonplaces are used by readers, writers, students, and scholars as an aid for remembering useful concepts or facts. Each one is unique to its creator's particular interests but they almost always include passages found in other texts, sometimes accompanied by the compiler's responses. They became significant in Early Modern Europe.

"Commonplace" is a translation of the Latin term locus communis (from Greek tópos koinós, see literary topos) which means "a general or common topic", such as a statement of proverbial wisdom. In this original sense, commonplace books were collections of such sayings, such as John Milton's example. Scholars now understand them to include manuscripts in which an individual collects material which have a common theme, such as ethics, or exploring several themes in one volume. Commonplace books are private collections of information, but they are not diaries or travelogues.

In 1685 the English Enlightenment philosopher John Locke wrote a treatise in French on commonplace books, translated into English in 1706 as A New Method of Making Common-Place-Books, "in which techniques for entering proverbs, quotations, ideas, speeches were formulated. Locke gave specific advice on how to arrange material by subject and category, using such key topics as love, politics, or religion. Commonplace books, it must be stressed, are not journals, which are chronological and introspective."

By the early eighteenth century they had become an information management device in which a note-taker stored quotations, observations and definitions. They were used in private households to collate ethical or informative texts, sometimes alongside recipes or medical formulae. For women, who were excluded from formal higher education, the commonplace book could be a repository of intellectual references. The gentlewoman Elizabeth Lyttelton kept one from the 1670s to 1713 and a typical example was published by Mrs Anna Jameson in 1855, including headings such as Ethical Fragments; Theological; Literature and Art. Commonplace books were used by scientists and other thinkers in the same way that a database might now be used: Carl Linnaeus, for instance, used commonplacing techniques to invent and arrange the nomenclature of his Systema Naturae (which is the basis for the system used by scientists today). The commonplace book was often a lifelong habit: for example the English-Australian artist Georgina McCrae kept a commonplace book from 1828-1865.

Defenestration (from Old French fenestre, inherited from Latin fenestra) is the act of throwing someone or something out of a window. The term was coined around the time of an incident in Prague Castle in the year 1618 which became the spark that started the Thirty Years' War. This was done in "good Bohemian style"; this referred to the defenestration which had occurred in Prague's City Hall almost 200 years earlier (July 1419), which also on that occasion led to war: the Hussite war. The word comes from the New Latin de- (down from) and fenestra (window or opening). Likewise, it can also refer to the condition of being thrown out of a window, as in "The Defenestration of Ermintrude Inch".

While the act of defenestration connotes the forcible or peremptory removal of an adversary, and the term is sometimes used in just that sense, it also suggests breaking the windows in the process (de- also means removal).

On the x86 computer architecture, a triple fault is a special kind of exception generated by the CPU when an exception occurs while the CPU is trying to invoke the double fault exception handler, which itself handles exceptions occurring while trying to invoke a regular exception handler.

x86 processors beginning with the 80286 will cause a shutdown cycle to occur when a triple fault is encountered. This typically causes the motherboard hardware to initiate a CPU reset, which, in turn, causes the whole computer to reboot.
