π Men Without Work: America's Invisible Crisis (Book)
Men Without Work: America's Invisible Crisis is a 2016 book by the American political economist Nicholas Eberstadt discussing the phenomenon of American men in their prime leaving the workforce. Statistically, the labor force involvement for men twenty and older fell from 86% to 68% between 1948 and 2015. The book discusses the history, causes, and implications of the phenomenon, as well as possible solutions.

π Crew resource management
Crew resource management or cockpit resource management (CRM) is a set of training procedures for use in environments where human error can have devastating effects. Used primarily for improving aviation safety, CRM focuses on interpersonal communication, leadership, and decision making in the cockpit of an airliner. Its pioneer was David Beaty, a former Royal Air Force pilot and later a BOAC pilot who wrote his seminal book The Human Factor in Aircraft Accidents in the late 1950s. Despite the considerable development of electronic aids since then, many principles he developed continue to prove effective today.
Crew resource management formally began with a National Transportation Safety Board (NTSB) recommendation made during their investigation of the 1978 United Airlines Flight 173 crash. The issues surrounding that crash included a DC-8 crew running out of fuel over Portland, Oregon while troubleshooting a landing gear problem.
The term "cockpit resource management" (later generalized to "crew resource management") was coined in 1979 by NASA psychologist John Lauber who had studied communication processes in cockpits for several years. While retaining a command hierarchy, the concept was intended to foster a less authoritarian cockpit culture, where co-pilots were encouraged to question captains if they observed them making mistakes.
Crew resource management grew out of the 1977 Tenerife airport disaster where two Boeing 747 aircraft collided on the runway killing 583 people. A few weeks later, NASA held a workshop on the topic, endorsing this innovative training. United Airlines was the first airline to provide CRM training for its cockpit crews in 1981. By the 1990s, it had become a global standard.
United Airlines additionally trained their flight attendants to use CRM in conjunction with the pilots to provide another layer of enhanced communication and teamwork. Studies have shown that by both work groups using CRM together, communication barriers are reduced and problems can be solved more efficiently, leading to increased safety. CRM training concepts have been modified for application to a wide range of activities where people must make dangerous time-critical decisions. These arenas include air traffic control, ship handling, firefighting, and medical operating rooms.

π Leachim β 4th grade teaching robot
Leachim was an early example of Diphone synthetic speech and demonstrated how voice branching could be done quickly via computer discs to create understandable speech (i.e. verbal output). This method combined phonemes, words, and sentences to form verbal responsive messages when prompted by the computer. The device received attention on a world-wide basis because hundreds of articles were written about it.

π Swatch Internet Time
Swatch Internet Time (or .beat time) is a decimal time concept introduced in 1998 by the Swatch corporation as part of their marketing campaign for their line of "Beat" watches.
Instead of hours and minutes, the mean solar day is divided into 1000 parts called ".beats". Each .beat is equal to one decimal minute in the French Revolutionary decimal time system and lasts 1 minute and 26.4 seconds (86.4 seconds) in standard time. Times are notated as a 3-digit number out of 1000 after midnight. So, for example @248 would indicate a time 248 .beats after midnight representing β248β1000 of a day, just over 5 hours and 57 minutes.
There are no time zones in Swatch Internet Time; instead, the new time scale of Biel Meantime (BMT) is used, based on Swatch's headquarters in Biel, Switzerland and equivalent to Central European Time, West Africa Time, and UTC+01. Unlike civil time in Switzerland and many other countries, Swatch Internet Time does not observe daylight saving time.

π Siemens Synthesizer β Studio for Electronic Music
The Siemens Synthesizer (or "Siemens Studio fΓΌr Elektronische Musik") was developed in Germany in 1959 by the German electronics manufacturer Siemens, originally to compose live electronic music for its own promotional films.
From 1956 to 1967, it had a significant influence on the development of electronic music. Among others, Mauricio Kagel, Henri Pousseur, Herbert BrΓΌn and Ernst Krenek completed important electronic works there.

π Thomas of Cana Copper Plates
The Thomas of Cana copper plates (Malayalam: Knai Thoma Cheppedu), or Knanaya copper plates, dated variously between 345 C.E. and 811 C.E., are a lost set of copper-plate grants issued by the unidentified Chera/Perumal king of Kerala "Co-qua-rangon" to Syriac Christian merchants led by Knai Thoma (anglicized as Thomas of Cana) in the city of "Makotayar Pattinam" (present day Kodungallur), south India. The royal charters were reportedly engraved in βMalabarβ, Chaldean and Arabic on both sides of two copper plates (joined by a ring). Archbishop Francis Ros notes in his 1604 account M.S. ADD 9853 that the plates were taken to Portugal by the Franciscan Order.
Scholar M.G.S. Narayanan tentatively identifies king βCo-qua-rangonβ with king Rama Rajasekhara (Co-qua-rangon β Ko Kotai Iraman β Rajadhiraja Rama) of the 9th century Chera Empire.
The Knanaya or the people of Knai Thoma were historically associated with the southern portion of the Chera/Perumal headquarters Kodungallur until in 1524 they were dispersed from the city due to conflict between the Kingdom of Cochin and the Kingdom of Calicut. The plate was cherished by the Knanaya as evidence of their arrival in Kerala under the leadership of Knai Thoma as well as a notation of the historical, economic, and social rights bestowed upon them by the Chera Perumal. The native Christian tradition places the arrival of Thomas of Cana in 345 C.E.
Translations of the existing Kollam Syrian Plates of the 9th century made by the Syrian Christian priest Ittimani in 1601 as well as the French Indologist Abraham Anquetil Duperron in 1758 both note that the one of the plates mentioned a brief of the arrival of Knai Thoma.It is believed that this was a notation of the previous rights bestowed upon the Christians by Cheraman Perumal. The contemporary set however does not mention this paragraph and is believed to be incomplete or a later inscription. Scholar of Early Christian history IstvΓ‘n Percvel theorizes that at one time the Kollam Syrian plates and the Thomas of Cana plates were kept together.

π Sequoyah β Inventor of the Cherokee Script
Sequoyah (αααα― Ssiquoya, as he signed his name, or ααα― Se-quo-ya, as is often spelled in Cherokee; named in English George Gist or George Guess) (c.1770β1843), was a Native American polymath of the Cherokee Nation. In 1821 he completed his independent creation of a Cherokee syllabary, making reading and writing in Cherokee possible. This was one of the very few times in recorded history that a member of a pre-literate people created an original, effective writing system (another example being Shong Lue Yang). After seeing its worth, the people of the Cherokee Nation rapidly began to use his syllabary and officially adopted it in 1825. Their literacy rate quickly surpassed that of surrounding European-American settlers.
