1994 Scotland RAF Chinook Crash
On 2 June 1994, a Chinook helicopter of the Royal Air Force (RAF), serial number ZD576, crashed on the Mull of Kintyre, Scotland, in foggy conditions. The crash resulted in the deaths of all twenty-five passengers and four crew on board. Among the passengers were almost all the United Kingdom's senior Northern Ireland intelligence experts. The accident is the RAF's worst peacetime disaster. In 1995, an RAF board of inquiry ruled that it was impossible to establish the exact cause of the accident. This ruling was subsequently overturned by two senior reviewing officers, who stated the pilots were guilty of gross negligence for flying too fast and too low in thick fog. This finding proved to be controversial, especially in light of irregularities and technical issues surrounding the then-new Chinook HC.2 variant which were uncovered. A Parliamentary inquiry conducted in 2001 found the previous verdict of gross negligence on the part of the crew to be 'unjustified'. In 2011, an independent review of the crash cleared the crew of negligence.

Tribe (Internet)
The term tribe or digital tribe is used as a slang term for an unofficial community of people who share a common interest, and usually who are loosely affiliated with each other through social media or other Internet mechanisms. The term is related to "tribe", which traditionally refers to people closely associated in both geography and genealogy. Nowadays, it looks more like a virtual community or a personal network and it is often called global digital tribe. Most anthropologists agree that a tribe is a (small) society that practices its own customs and culture, and that these define the tribe. The tribes are divided into clans, with their own customs and cultural values that differentiate them from activities that occur in 'real life' contexts. People feel more inclined to share and defend their ideas on social networks than they would dare to say to someone face to face. For example, it would be ridiculous to 'poke' someone in real life.

IBM Building (Honolulu)
The IBM Building is an office building in Honolulu located at 1240 Ala Moana Boulevard. Designed by Vladimir Ossipoff, the building opened in 1962 as the Honolulu headquarters for IBM. It is presently owned by Howard Hughes Corporation, serving as a sales center for their surrounding Ward Village development. Construction of the IBM Building cost $1,500,000 (equivalent to $12,678,218 in 2019). The building was dedicated on October 10, 1962, in a ceremony attended by officials including then-Governor of Hawaii William F. Quinn. The roughly cube-shaped structure is distinguished by the honeycomb structure of its concrete brise soleil, inspired by Polynesian culture and also intended to resemble the punched cards used in the computer industry at the time of its construction. The building was slated for demolition by then-owner GGP Inc. as part of a 2008 redevelopment plan, but public backlash led to its preservation after the planned development area was purchased by Howard Hughes Corporation, which expressed an intent to maintain the IBM Building's name and general appearance. The development company instead renovated the building to use as an information and sales center for their surrounding Ward Village development.

Chaldean Oracles
The Chaldean Oracles are a set of spiritual and philosophical texts widely used by Neoplatonist philosophers from the 3rd to the 6th century C.E. While the original texts have been lost, they have survived in the form of fragments consisting mainly of quotes and commentary by Neoplatonist writers. They were likely to have originally formed a single mystery-poem, which may have been in part compiled, in part received via trance, by Julian the Chaldean, or more likely, his son, Julian the Theurgist in the 2nd century C.E. Later Neoplatonists, such as Iamblichus and Proclus, rated them highly. The 4th-century Emperor Julian (not to be confused with Julian the Chaldean or Julian the Theurgist) suggests in his Hymn to the Magna Mater that he was an initiate of the God of the Seven Rays, and was an adept of its teachings. When Christian Church Fathers or other Late Antiquity writers credit "the Chaldeans", they are probably referring to this tradition. An analysis of the Chaldean Oracles demonstrates an inspiration for contemporary gnostic teachings: fiery emanations initiate from the transcendental First Paternal Intellect, from whom the Second Intellect, the Demiurge comprehends the cosmos as well as himself. Within the First Intellect, a female Power, designated Hecate, is, like Sophia, the mediating World-Soul. At the base of all lies created Matter, made by the Demiurgic Intellect. The matter farthest from the Highest God (First Father / Intellect) was considered a dense shell from which the enlightened soul must emerge, shedding its bodily garments. A combination of ascetic conduct and correct ritual are recommended to free the soul from the confines of matter and limitations, and to defend it against the demonic powers lurking in some of the realms between Gods and mortals.

Nike+
The Nike+iPod Sports Kit is an activity tracker device, developed by Nike, Inc., which measures and records the distance and pace of a walk or run. The Nike+iPod consists of a small transmitter device attached to or embedded in a shoe, which communicates with either the Nike+ Sportband, a receiver plugged into an iPod Nano. It can also work directly with a 2nd Generation iPod Touch (or higher), iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPhone 5C, iPhone 5S, or a Nike+ Sportwatch. If using the iPod or the iPhone, iTunes software can be used to view the walk or run history. The Nike+iPod was announced on May 23, 2006. On September 7, 2010, Nike released the Nike+ Running App (originally called Nike+ GPS) on the App Store, which used a tracking engine powered by MotionX that does not require the separate shoe sensor or pedometer. This application works using the accelerometer and GPS of the iPhone and the accelerometer of the iPod Touch, which does not have a GPS chip. Nike+Running is compatible with the iPhone 6 and iPhone 6 Plus down to iPhone 3GS and iPod touch. On June 21, 2012, Nike released Nike+ Running App for Android. The current app is compatible with all Android phones running 4.0.3 and up.

Focal Point (Game Theory)
In game theory, a focal point (or Schelling point) is a solution that people tend to choose by default in the absence of communication. The concept was introduced by the American economist Thomas Schelling in his book The Strategy of Conflict (1960). Schelling states that "(p)eople can often concert their intentions or expectations with others if each knows that the other is trying to do the same" in a cooperative situation (at page 57), so their action would converge on a focal point which has some kind of prominence compared with the environment. However, the conspicuousness of the focal point depends on time, place and people themselves. It may not be a definite solution.
