Cyc (pronounced SYKE, ) is a long-living artificial intelligence project that aims to assemble a comprehensive ontology and knowledge base that spans the basic concepts and rules about how the world works. Hoping to capture common sense knowledge, Cyc focuses on implicit knowledge that other AI platforms may take for granted. This is contrasted with facts one might find somewhere on the internet or retrieve via a search engine or Wikipedia. Cyc enables AI applications to perform human-like reasoning and be less "brittle" when confronted with novel situations.

Douglas Lenat began the project in July 1984 at MCC, where he was Principal Scientist 1984–1994, and then, since January 1995, has been under active development by the Cycorp company, where he is the CEO.

Live in Cook County Jail is a 1971 live album by American blues musician B.B. King, recorded on September 10, 1970, in Cook County Jail in Chicago. Agreeing to a request by jail warden Winston Moore, King and his band performed for an audience of 2,117 prisoners, most of whom were young black men. King's set list consisted mostly of slow blues songs, which had been hits earlier in his career. When King told ABC Records about the upcoming performance, he was advised to bring along press and recording equipment.

Live in Cook County Jail spent thirty-three weeks on the Billboard Top LPs chart, where it peaked at number twenty-five. It also reached number one on the Top R&B chart, King's only album to do so. In addition to positive reviews from critics, much of the press surrounding Live in Cook County Jail focused on the harsh living conditions in the prison, which led to an eventual reform.

Although Live in Cook County Jail continues to receive praise as one of King's best albums, critics often overlook it in favor of 1965's Live at the Regal. Rolling Stone ranked Live in Cook County Jail at number 499 on its list of the 500 Greatest Albums of All Time, and in 2002, it was inducted into the Blues Foundation Hall of Fame. The performance at Cook County Jail had a profound impact on King, who not only continued to perform free concerts at prisons throughout his life, but also co-established the Foundation for the Advancement of Inmate Rehabilitation and Recreation.

Abu Rayhan al-Biruni (973 – after 1050) was a Persian scholar and polymath. He was from Khwarazm – a region which encompasses modern-day western Uzbekistan, and northern Turkmenistan.

Al-Biruni was well versed in physics, mathematics, astronomy, and natural sciences, and also distinguished himself as a historian, chronologist and linguist. He studied almost all fields of science and was compensated for his research and strenuous work. Royalty and powerful members of society sought out Al-Biruni to conduct research and study to uncover certain findings. He lived during the Islamic Golden Age. In addition to this type of influence, Al-Biruni was also influenced by other nations, such as the Greeks, who he took inspiration from when he turned to studies of philosophy. He was conversant in Khwarezmian, Persian, Arabic, Sanskrit, and also knew Greek, Hebrew and Syriac. He spent much of his life in Ghazni, then capital of the Ghaznavid dynasty, in modern-day central-eastern Afghanistan. In 1017 he travelled to the Indian subcontinent and authored a study of Indian culture Tārīkh al-Hind (History of India) after exploring the Hindu faith practiced in India. He was given the title "founder of Indology". He was an impartial writer on customs and creeds of various nations, and was given the title al-Ustadh ("The Master") for his remarkable description of early 11th-century India.

The East German balloon escape occurred on 16 September 1979, when eight people in two families escaped the Eastern Bloc country of East Germany by crossing the border to the Western Bloc's West Germany in a homemade hot air balloon at around 2:00 a.m. The escape plot was carried out over one and a half years, including a previously unsuccessful attempt, three different balloons, and various modifications. One failed crossing alerted the government to the plot, but the police were not able to identify the suspects before their flight to the West.

🔗 Psychology

A granfalloon, in the fictional religion of Bokononism (created by Kurt Vonnegut in his 1963 novel Cat's Cradle), is defined as a "false karass". That is, it is a group of people who affect a shared identity or purpose, but whose mutual association is meaningless.

As quoted in And So It Goes: Kurt Vonnegut: A Life (2011) by Charles J. Shields, Vonnegut writes in his introduction to Wampeters, Foma and Granfalloons (1974) that a "granfalloon is a proud and meaningless collection of human beings"; Shields also comments that in the same book, Vonnegut later cites the demonym of 'Hoosiers' as "one of [Vonnegut's] favorite examples" of what the term embodies.

Robert Burnham Jr. (June 16, 1931 – March 20, 1993) was an American astronomer, best known for writing the classic three-volume Burnham's Celestial Handbook. He is the discoverer of numerous asteroids including the Mars crossing asteroid 3397 Leyla, as well as six comets.

Burnham's late years were tragic; he died destitute and alone. However, he is remembered by a generation of deep sky observers for his unique contribution to astronomy, the Celestial Handbook. The main-belt asteroid 3467 Bernheim was named in his honor.

🔗 Philosophy 🔗 Philosophy/Philosophy of mind

The hard problem of consciousness is the problem of explaining why and how sentient organisms have qualia or phenomenal experiences—how and why it is that some internal states are subjective, felt states, such as heat or pain, rather than merely nonsubjective, unfelt states, as in a thermostat or a toaster. The philosopher David Chalmers, who introduced the term "hard problem" of consciousness, contrasts this with the "easy problems" of explaining the ability to discriminate, integrate information, report mental states, focus attention, and so forth. Easy problems are (relatively) easy because all that is required for their solution is to specify a mechanism that can perform the function. That is, regardless of how complex or poorly understood the phenomena of the easy problems may be, they can eventually be understood by relying entirely on standard scientific methodologies. Chalmers claims that the problem of experience is distinct from this set and will "persist even when the performance of all the relevant functions is explained".

The existence of a "hard problem" is controversial. It has been accepted by philosophers of mind such as Joseph Levine, Colin McGinn, and Ned Block and cognitive neuroscientists such as Francisco Varela, Giulio Tononi, and Christof Koch. However, its existence is disputed by philosophers of mind such as Daniel Dennett, Massimo Pigliucci, and Keith Frankish and cognitive neuroscientists such as Stanislas Dehaene and Bernard Baars.

🔗 Cryptography 🔗 Cryptography/Computer science

Shamir's Secret Sharing is an algorithm in cryptography created by Adi Shamir. It is a form of secret sharing, where a secret is divided into parts, giving each participant its own unique part.

To reconstruct the original secret, a minimum number of parts is required. In the threshold scheme this number is less than the total number of parts. Otherwise all participants are needed to reconstruct the original secret.
