Ein Sof
Ein Sof, or Ayn Sof (/eɪn sɒf/, Hebrew: אין סוף), in Kabbalah, is understood as God prior to his self-manifestation in the production of any spiritual realm, probably derived from Ibn Gabirol's term, "the Endless One" (she-en lo tiklah). Ein Sof may be translated as "no end", "unending", "there is no end", or infinity. It was first used by Azriel ben Menahem, who, sharing the Neoplatonic belief that God can have no desire, thought, word, or action, emphasized by it the negation of any attribute. Of the Ein Sof, nothing ("Ein") can be grasped ("Sof"-limitation). It is the origin of the Ohr Ein Sof, the "Infinite Light" of paradoxical divine self-knowledge, nullified within the Ein Sof prior to creation. In Lurianic Kabbalah, the first act of creation, the Tzimtzum self "withdrawal" of God to create an "empty space", takes place from there. In Hasidism, the Tzimtzum is only illusionary concealment of the Ohr Ein Sof, giving rise to monistic panentheism. Consequently, Hasidism focuses on the Atzmus divine essence, rooted higher within the Godhead than the Ein Sof, which is limited to infinitude, and reflected in the essence (Etzem) of the Torah and the soul.
Ayn
Ayn may refer to:
Ayin
Ayin or Ayn is the sixteenth letter of the Semitic abjads, including Phoenician ʿAyin 
, Hebrew ʿAyin ע, Aramaic ʿĒ 
, Syriac ʿĒ ܥ, and Arabic ʿAyn ع (where it is sixteenth in abjadi order only). ﻉ comes twenty‐first in the New Persian alphabet and eighteenth in Arabic hijaʾi order.
The ʿayin glyph in these various languages represents, or has represented, a voiced pharyngeal fricative (/ʕ/), or a similarly articulated consonant, which has no equivalent or approximate substitute in the sound‐system of English. There are many possible transliterations.
Origins
The letter name is derived from Proto-Semitic *ʿayn- "eye", and the Phoenician letter had an eye-shape, ultimately derived from the ı͗r hieroglyph
To this day, ʿayin in Hebrew, Arabic, Amharic, and Maltese means "eye" and "spring" (ʿayno in Neo-Aramaic).
The Phoenician letter gave rise to the Greek Ο, Latin O, and Cyrillic О, all representing vowels.
The sound represented by ayin is common to much of the Afrasiatic language family, such as the Egyptian, Cushitic, and Semitic languages. Some scholars believe that the sound in Proto-Indo-European transcribed h3 was similar, though this is debatable. (See Laryngeal theory.)
Ghayn
The Arabic letter غ (Arabic: غين ghayn or ġayn) is the nineteenth letter of the Arabic alphabet, one of the six letters not in the twenty-two akin to the Phoenician alphabet (the others being thāʼ, khāʼ, dhāl, ḍād, ẓāʼ). It is the twenty-second letter in the new Persian alphabet. It represents the sound /ɣ/ or /ʁ/. In Persian language it represents [ɣ]~[ɢ]. In name and shape, it is a variant of ʻayn (ع). Its numerical value is 1000 (see Abjad numerals).
A voiced velar fricative /ɣ/ or a voiced uvular fricative /ʁ/ (usually reconstructed for Proto-Semitic) merged with ʻayin in most languages except for Arabic, Ugaritic, and older varieties of the Canaanite languages. Canaanite languages and Hebrew later also merged it with ʻayin, and this merger was complete in Tiberian Hebrew. The South Arabian alphabet retained a symbol for ġ, 
.
The letter ghayn (غ) is sometimes used to represent the voiced velar plosive /ɡ/ in loan words and names in Arabic and is then often pronounced /ɡ/, not /ɣ/, such as the word for Bulgaria (بلغاريا). Other letters, such as ج, ق, ک/ك (also گ, ݣ, ݢ, ڨ, ڠ, instead of the original Arabic letters), can be used to transcribe /ɡ/ in loan words and names, depending on whether the local variety of Arabic in the country has the phoneme /ɡ/, which letter represents it if it does, and on whether it is customary in the country to use that letter to transcribe /ɡ/. For instance, in Egypt, where ج is pronounced as [ɡ] in all situations, even when speaking Modern Standard Arabic (except in certain contexts, such as reciting the Qur'an), ج is used to transcribe foreign [ɡ] in virtually all contexts. In many cases غ is pronounced in loan words as expected—/ɣ/, not /ɡ/—even though the original language had /ɡ/.
Soldier of Fortune II: Double Helix
Soldier of Fortune II: Double Helix is a video game created by Raven Software, a sequel to Soldier of Fortune. It was developed using the Quake III: Team Arena engine. Once again, Raven hired John Mullins to act as a consultant on the game. Based on comments and criticisms of the original game, Raven Software developed Soldier of Fortune II to be a more "realistic" game, with tactical shooters like Operation Flashpoint: Cold War Crisis and Tom Clancy's Rainbow Six as inspirations rather than Quake. A sequel titled Soldier of Fortune: Payback, made by Cauldron HQ was released for Microsoft Windows, PlayStation 3 and Xbox 360 in 2007.
Story
The theme of the sequel is germ warfare, as the mercenary Mullins and his new partner Madeline Taylor travel to Colombia to investigate a viral outbreak in a small town, only to link it to a shadowy organization called Prometheus. The virus, called Romulus, is followed by a computer virus called Remus which is programmed to delete files on any computer in the world, in this case, files relating to Prometheus and Romulus, so an anti-virus cannot be formulated. Prometheus then plans to blackmail the G8 countries at a summit in Switzerland for billions of dollars. It is revealed throughout the course of the game that a mole inside The Shop may be feeding information to the terrorists.
Soldier of Fortune: Payback
Soldier of Fortune: Payback is a first-person shooter video game and the third installment of the Soldier of Fortune game series. Unlike the previous two Soldier of Fortune games, which were developed by Raven Software utilizing the Quake 2 and Quake 3 engines, Payback was developed by Cauldron HQ, developed with Cauldron's in-house CloakNT engine, used in their previous first person shooter game, Chaser. It is the first game of the series released for the Xbox 360 and PlayStation 3. The game was released on 14 November 2007.
Synopsis
The player no longer takes the role of John Mullins, the hero of the first two titles in the Soldier of Fortune. In fact Payback has little in common with its predecessors except for excessive gore and violence.
After freelance mercenary Thomas Mason (Kyle Herbert) is betrayed by his comrade during a mission, he swears revenge against a worldwide terrorist organization that brands all of its operatives with the same tattoo on their necks.
Thionyl tetrafluoride
Thionyl tetrafluoride is an inorganic compound gas with the formula SOF4. It is also known as sulfur tetrafluoride oxide. The shape of the molecule is a distorted trigonal bipyramid. The oxygen is found on the equator. The atoms on the equator have shorter bond lengths than the fluorine atoms on the axis. The sulfur oxygen bond is 1.409Å. A S-F bond on the axis has length 1.596Å and the S-F bond on the equator has length 1.539Å. The angle between the equatorial fluorine atoms is 112.8°. The angle between axial fluorine and oxygen is 97.7°. The angle between oxygen and equatorial fluorine is 123.6° and between axial and equatorial fluorine is 85.7°. The fluorine atoms only produce one NMR line, probably because they exchange positions.
Formation
Thionyl fluoride reacting with fluorine gas can produce thionyl tetrafluoride. This was how the gas was first discovered by Moissan and Lebeau in 1902. They identified the formula by the pressure changes resulting from the reaction. Silver fluoride and platinum are capable of catalyzing the reaction.
