Gematria (; Hebrew: גמטריא or gimatria גימטריה, plural גמטראות or גימטריאות, gimatriot) is the practice of assigning a numerical value to a name, word or phrase by reading it as a number, or sometimes by using an alphanumerical cipher. The letters of the alphabets involved have standard numerical values, but a word can yield several values if a cipher is used.

According to Aristotle (384–322 BCE), isopsephy, based on the Milesian numbering of the Greek alphabet developed in the Greek city of Miletus, was part of the Pythagorean tradition, which originated in the 6th century BCE. The first evidence of use of Hebrew letters as numbers dates to 78 BCE; gematria is still used in Jewish culture. Similar systems have been used in other languages and cultures, derived from or inspired by either Greek isopsephy or Hebrew gematria, and include Arabic abjad numerals and English gematria.

The most common form of Hebrew gematria is used in the Talmud and Midrash, and elaborately by many post-Talmudic commentators. It involves reading words and sentences as numbers, assigning numerical instead of phonetic value to each letter of the Hebrew alphabet. When read as numbers, they can be compared and contrasted with other words or phrases – cf. the Hebrew proverb נכנס יין יצא סוד (nichnas yayin yatza sod, lit. 'wine entered, secret went out', i.e. "in vino veritas"). The gematric value of יין ('wine') is 70 (י=10; י=10; ן=50) and this is also the gematric value of סוד ('secret', ס=60; ו=6; ד=4)‎.

Although a type of gematria system ('Aru') was employed by the ancient Babylonian culture, their writing script was logographic, and the numerical assignments they made were to whole words. Aru was very different from the Milesian systems used by Greek and Hebrew cultures, which used alphabetic writing scripts. The value of words with Aru were assigned in an entirely arbitrary manner and correspondences were made through tables, and so cannot be considered a true form of gematria.

Gematria sums can involve single words, or a string of lengthy calculations. A short example of Hebrew numerology that uses gematria is the word חי (chai, lit. 'alive'), which is composed of two letters that (using the assignments in the mispar gadol table shown below) add up to 18. This has made 18 a "lucky number" among the Jewish people. Donations of money in multiples of 18 are very popular.

In early Jewish sources, the term can also refer to other forms of calculation or letter manipulation, for example atbash.

The Tamagotchi Connection, known as Tamagotchi Plus in Japan and Tamagotchi Connexion in the UK, is a virtual pet in the Tamagotchi line of digital toys from Bandai. The Tamagotchi Connection is unique from prior models in that it uses infrared technology to connect and interact with other devices and was first released in 2004, 8 years after the first Tamagotchi toy. Using the device's infrared port, the virtual pet (referred to as a Tamagotchi) can make friends with other Tamagotchis, in addition to playing games, giving and receiving presents and having a baby.

Versions 1 to 4 of Tamagotchi Connection have 6 levels of friendship that can be viewed in the Friends List:

• Acquaintance (one smiley-face)
• Buddy (two smiley-faces)
• Friend (three smiley-faces)
• Good friend (four smiley-faces)
• Best friend (two love-hearts, two smiley-faces, during connection they may kiss)
• Partner (four love-hearts, during connection they will kiss and may have babies)

Versions 5 and 6 have different levels.

If the Tamagotchi cannot find a partner from another device to have babies with, a matchmaker will come, allowing the Tamagotchi to have a baby with a computer-controlled Tamagotchi character. This applies to versions 1 to 4 and 6 only. Version 5 introduces a Dating Show game in which the user must play to gain a CPU partner.

🔗 Physics 🔗 Physics/relativity

In physics, there is a speculative hypothesis that, if there were a black hole with the same mass, charge and angular momentum as an electron, it would share other properties of the electron. Most notably, Brandon Carter showed in 1968 that the magnetic moment of such an object would match that of an electron. This is interesting because calculations ignoring special relativity and treating the electron as a small rotating sphere of charge give a magnetic moment roughly half the experimental value (see Gyromagnetic ratio).

However, Carter's calculations also show that a would-be black hole with these parameters would be "super-extremal". Thus, unlike a true black hole, this object would display a naked singularity, meaning a singularity in spacetime not hidden behind an event horizon. It would also give rise to closed timelike curves.

Standard quantum electrodynamics (QED), currently the most comprehensive theory of particles, treats the electron as a point particle. There is no evidence that the electron is a black hole (or naked singularity) or not. Furthermore, since the electron is quantum-mechanical in nature, any description purely in terms of general relativity is paradoxical until a better model based on understanding of quantum nature of blackholes and gravitational behaviour of quantum particles is developed by research. Hence, the idea of a black hole electron remains strictly hypothetical.

The FM Towns (Japanese: エフエムタウンズ, Hepburn: Efu Emu Taunzu) is a Japanese personal computer built by Fujitsu from February 1989 to the summer of 1997. It started as a proprietary PC variant intended for multimedia applications and PC games, but later became more compatible with IBM PC compatibles. In 1993, the FM Towns Marty was released, a game console compatible with existing FM Towns games.

The "FM" part of the name means "Fujitsu Micro" like their earlier products, while the "Towns" part is derived from the code name the system was assigned while in development, "Townes". This refers to Charles Townes, one of the winners of the 1964 Nobel Prize in Physics, following a custom of Fujitsu at the time to code name PC products after Nobel Prize winners. The e in "Townes" was dropped when the system went into production to make it clearer that the term was to be pronounced like the word "towns" rather than the potential "tow-nes".

Google was officially launched in 1998 by Larry Page and Sergey Brin to market Google Search, which has become the most used web-based search engine. Larry Page and Sergey Brin, students at Stanford University in California, developed a search algorithm at first known as "BackRub" in 1996, with the help of Scott Hassan and Alan Steremberg. The search engine soon proved successful and the expanding company moved several times, finally settling at Mountain View in 2003. This marked a phase of rapid growth, with the company making its initial public offering in 2004 and quickly becoming one of the world's largest media companies. The company launched Google News in 2002, Gmail in 2004, Google Maps in 2005, Google Chrome in 2008, and the social network known as Google+ in 2011 (which was shut down in April 2019), in addition to many other products. In 2015, Google became the main subsidiary of the holding company Alphabet Inc.

The search engine went through many updates in attempts to eradicate search engine optimization.

Google has engaged in partnerships with NASA, AOL, Sun Microsystems, News Corporation, Sky UK, and others. The company set up a charitable offshoot, Google.org, in 2005.

The name Google is a misspelling of Googol, the number 1 followed by 100 zeros, which was picked to signify that the search engine was intended to provide large quantities of information.

The Druze (; Arabic: دَرْزِيٌّ, darzī or Arabic: دُرْزِيٌّ durzī, pl. دُرُوزٌ, durūz), known to adherents as al-Muwaḥḥidūn (Monotheists) or Muwaḥḥidūn (unitarians), are an Arab and Arabic-speaking esoteric ethnoreligious group from Western Asia who adhere to the Druze faith, an Abrahamic, monotheistic, syncretic, and ethnic religion whose main tenets are the unity of God and the belief in reincarnation and the eternity of the soul. Adherents of the Druze religion call themselves simply "the Monotheists" (al-Muwaḥḥidūn). Most Druze religious practices are kept secret. The Druze do not permit outsiders to convert to their religion. Marriage outside the Druze faith is rare and strongly discouraged.

The Epistles of Wisdom is the foundational and central text of the Druze faith. The Druze faith incorporates elements of Isma'ilism, Christianity, Gnosticism, Neoplatonism, Zoroastrianism, Buddhism, Hinduism, Pythagoreanism, and other philosophies and beliefs, creating a distinct and secretive theology based on an esoteric interpretation of scripture, which emphasizes the role of the mind and truthfulness. Druze believe in theophany and reincarnation. Druze believe that at the end of the cycle of rebirth, which is achieved through successive reincarnations, the soul is united with the Cosmic Mind (al-ʻaql al-kullī).

The Druze have a special reverence for Shuaib, who they believe is the same person as the biblical Jethro. The Druze believe that Adam, Noah, Abraham, Moses, Jesus, Muhammad, and Isma'il ibn Ja'far were prophets. Druze tradition also honors and reveres Salman the Persian, al-Khidr (who they identify as Elijah, reborn as John the Baptist and Saint George), Job, Luke the Evangelist, and others as "mentors" and "prophets".

Even though the faith originally developed out of Isma'ilism, the Druze are not Muslims. The Druze faith is one of the major religious groups in the Levant, with between 800,000 and a million adherents. They are found primarily in Lebanon, Syria, and Israel, with small communities in Jordan. They make up 5.5% of the population of Lebanon, 3% of Syria and 1.6% of Israel. The oldest and most densely-populated Druze communities exist in Mount Lebanon and in the south of Syria around Jabal al-Druze (literally the "Mountain of the Druze").

The Druze community played a critically important role in shaping the history of the Levant, where it continues to play a significant political role. As a religious minority in every country in which they are found, they have frequently experienced persecution by different Muslim regimes, including contemporary Islamic extremism.

The dihydrogen monoxide parody involves calling water by an unfamiliar chemical name, most often "dihydrogen monoxide" (DHMO), and listing some of water's well-known effects in a particularly alarming manner, such as accelerating corrosion and causing suffocation. The parody often calls for dihydrogen monoxide to be banned, regulated, or labeled as dangerous. It demonstrates how a lack of scientific literacy and an exaggerated analysis can lead to misplaced fears.

The parody has been used with other chemical names, including "dihydrogen oxide", "hydroxyl acid", and "hydroxylic acid".

Invented traditions are cultural practices that are presented or perceived as traditional, arising from the people starting in the distant past, but which in fact are relatively recent and often even consciously invented by identifiable historical actors. The concept was highlighted in the 1983 book The Invention of Tradition, edited by Eric Hobsbawm and Terence Ranger. Hobsbawm's introduction argues that many "traditions" which "appear or claim to be old are often quite recent in origin and sometimes invented." This "invention" is distinguished from "starting" or "initiating" a tradition that does not then claim to be old. The phenomenon is particularly clear in the modern development of the nation and of nationalism, creating a national identity promoting national unity, and legitimising certain institutions or cultural practices.

The Yenish (German: Jenische; French: Yéniche) are an itinerant group in Western Europe who live mostly in Germany, Austria, Switzerland, Luxembourg, Belgium, and parts of France, roughly centred on the Rhineland. A number of theories for the group's origins have been proposed, including that the Yenish descended from members of the marginalized and vagrant poor classes of society of the early modern period, before emerging as a distinct group by the early 19th century. Most of the Yenish became sedentary in the course of the mid-19th to 20th centuries.

Microsoft Works is a discontinued productivity software suite developed by Microsoft and sold from 1987 to 2009. Its core functionality included a word processor, a spreadsheet and a database management system. Later versions had a calendar application and a dictionary while older releases included a terminal emulator. Works was available as a standalone program, and as part of a namesake home productivity suite. Because of its low cost ($40 retail, or as low as $2 OEM), companies frequently pre-installed Works on their low-cost machines. Works was smaller, less expensive, and had fewer features than Microsoft Office and other major office suites available at the time.

Mainstream support for the final standalone and suite release ended on October 9, 2012 and January 8, 2013, respectively.
