The King in Yellow is a book of short stories by American writer Robert W. Chambers, first published by F. Tennyson Neely in 1895. The British first edition was published by Chatto & Windus in 1895 (316 pages).

The book contains nine short stories and a sequence of poems; while the first stories belong to the genres of supernatural horror and weird fiction, The King in Yellow progressively transitions towards a more light-hearted tone, ending with romantic stories devoid of horror or supernatural elements. The horror stories are highly esteemed, and it has been described by critics such as E. F. Bleiler, S. T. Joshi, and T. E. D. Klein as a classic in the field of the supernatural. Lin Carter called it "an absolute masterpiece, probably the single greatest book of weird fantasy written in this country between the death of Poe and the rise of Lovecraft", and it was an influence on Lovecraft himself.

The book is named for the eponymous play within the stories which recurs as a motif through the first four stories, a forbidden play which induces madness in those who read it.

Hybrid Insect Micro-Electro-Mechanical Systems (HI-MEMS) is a project of DARPA, a unit of the United States Department of Defense. Created in 2006, the unit's goal is the creation of tightly coupled machine-insect interfaces by placing micro-mechanical systems inside the insects during the early stages of metamorphosis. After implantation, the "insect cyborgs" could be controlled by sending electrical impulses to their muscles. The primary application is surveillance. The project was created with the ultimate goal of delivering an insect within 5 meters of a target located 100 meters away from its starting point. In 2008, a team from the University of Michigan demonstrated a cyborg unicorn beetle at an academic conference in Tucson, Arizona. The beetle was able to take off and land, turn left or right, and demonstrate other flight behaviors. Researchers at Cornell University demonstrated the successful implantation of electronic probes into tobacco hornworms in the pupal stage.

The Exploratorium is a museum of science, technology, and arts in San Francisco. Its mission is to create inquiry-based experiences that transform learning worldwide. It has been described by the New York Times as the most important science museum to have opened since the mid-20th century, an achievement attributed to "the nature of its exhibits, its wide-ranging influence and its sophisticated teacher training program". Characterized as "a mad scientist's penny arcade, a scientific funhouse, and an experimental laboratory all rolled into one", the participatory nature of its exhibits and its self-identification as a center for informal learning has led to it being cited as the prototype for participatory museums around the world.

The Exploratorium was founded by physicist and educator Frank Oppenheimer and opened in 1969 at the Palace of Fine Arts, its home until January 2, 2013. On April 17, 2013, the Exploratorium reopened at Piers 15 and 17 on San Francisco's Embarcadero. The historic interior and exterior of Pier 15 was renovated extensively prior to the move, and is divided into several galleries mainly separated by content, including the physics of seeing and listening (Light and Sound), Human Behavior, Living Systems, Tinkering (including electricity and magnetism), the Outdoor Gallery, and the Bay Observatory Gallery, which focuses on local environment, weather, and landscape.

Since the museum's founding, over 1,000 participatory exhibits have been created, approximately 600 of which are on the floor at any given time. The exhibit-building workshop space is contained within the museum and is open to view. In addition to the public exhibition space, the Exploratorium has been engaged in the professional development of teachers, science education reform, and the promotion of museums as informal education centers since its founding. Since Oppenheimer's death in 1985, the Exploratorium has expanded into other domains, including its 50,000-page website and two iPad apps on sound and color. It has also inspired an international network of participatory museums working to engage the public with general science education. The new Exploratorium building is also working to showcase environmental sustainability efforts as part of its goal to become the largest net-zero museum in the country.

The Exploratorium offers visitors a variety of ways—including exhibits, webcasts, websites and events—for visitors to explore and understand the world around them. In 2011, the Exploratorium received the National Science Board 2011 Public Service Science Award for its contributions to public understanding of science and engineering.

🔗 Philosophy 🔗 Philosophy/Logic 🔗 Philosophy/Epistemology

In epistemology, the Münchhausen trilemma is a thought experiment used to demonstrate the impossibility of proving any truth, even in the fields of logic and mathematics. If it is asked how any given proposition is known to be true, proof may be provided. Yet that same question can be asked of the proof, and any subsequent proof. The Münchhausen trilemma is that there are only three options when providing further proof in response to further questioning:

• The circular argument, in which the proof of some proposition is supported only by that proposition
• The regressive argument, in which each proof requires a further proof, ad infinitum
• The axiomatic argument, which rests on accepted precepts which are merely asserted rather than defended

The trilemma, then, is the decision among the three equally unsatisfying options.

The name Münchhausen-Trilemma was coined by the German philosopher Hans Albert in 1968 in reference to a trilemma of "dogmatism versus infinite regress versus psychologism" used by Karl Popper. It is a reference to the problem of "bootstrapping", based on the story of Baron Munchausen (in German, "Münchhausen") pulling himself and the horse on which he was sitting out of a mire by his own hair.

It is also known as Agrippa's trilemma or the Agrippan trilemma after a similar argument reported by Sextus Empiricus, which was attributed to Agrippa the Skeptic by Diogenes Laërtius, as well as Fries's trilemma after German philosopher Jakob Friedrich Fries. Sextus' argument, however, consists of five (not three) "modes". Popper in his original 1935 publication mentions neither Sextus nor Agrippa, but attributes his trilemma to Fries.

In contemporary epistemology, advocates of coherentism are supposed to accept the "circular" horn of the trilemma; foundationalists rely on the axiomatic argument. The view that accepts infinite regress is called infinitism.

Musth or must (an Urdu word, from Persian, lit. drunk) is a periodic condition in bull (male) elephants characterized by highly aggressive behavior and accompanied by a large rise in reproductive hormones.

Testosterone levels in an elephant in musth can be on average 60 times greater than in the same elephant at other times (in specific individuals these testosterone levels can even reach as much as 140 times the normal). However, whether this hormonal surge is the sole cause of musth, or merely a contributing factor, is unknown.

Scientific investigation of musth is problematic because even the most placid elephants become highly violent toward humans and other elephants during musth.

🔗 Death 🔗 Iran 🔗 Archaeology

The Hasanlu Lovers are a pair of human remains found at the Teppe Hasanlu archaeological site, located in the Naqadeh in the West Azerbaijan Province of Iran. Around 800 BCE, the city of Hasanlu, located in north-western Iran, was destroyed by an unknown invader. Inhabitants were slain and left where they fell. In 1973, the lovers were discovered by a team of archaeologists from the University of Pennsylvania led by Robert H. Dyson.

The two human skeletons were found together in a bin during excavations, seemingly embracing at the time of death, with no other objects except a stone slab under the head of one skeleton. They died together around 800 BCE, during the last destruction of the Hasanlu. Approximately 246 skeletons were found at the site altogether. How the lovers died and ended up in the bin is still under speculation but both skeletons lack evidence of injury near the time of death and possibly died of asphyxiation. They were exhibited at the Penn Museum from 1974 until the mid-1980s.

The right skeleton, referred to as HAS 73-5-799 (SK 335), is lying on its back and the left skeleton, referred to as HAS 73-5-800 (SK 336), is lying on its left side facing SK 335. When excavated, the skeletons were tested to determine various characteristics. Dental evidence suggest SK 335 was a young adult, possibly 19–22 years of age. Researchers identified the skeleton as male largely based on the pelvis. The skeleton had no apparent evidence of disease or healed lifetime injuries. Skeleton SK 336 appeared to have been healthy in life; the skeleton had no apparent evidence of healed lifetimes injuries, and was estimated to have been aged to about 30–35 years. Sex determination of the left skeleton was less definitive. Evidence suggests SK 336 was also male after being originally identified as female. The skeletons have been a subject of debate since they were first excavated.

🔗 Computing 🔗 Computer science 🔗 Computing/Software

Cyclomatic complexity is a software metric used to indicate the complexity of a program. It is a quantitative measure of the number of linearly independent paths through a program's source code. It was developed by Thomas J. McCabe, Sr. in 1976.

Cyclomatic complexity is computed using the control-flow graph of the program: the nodes of the graph correspond to indivisible groups of commands of a program, and a directed edge connects two nodes if the second command might be executed immediately after the first command. Cyclomatic complexity may also be applied to individual functions, modules, methods or classes within a program.

One testing strategy, called basis path testing by McCabe who first proposed it, is to test each linearly independent path through the program; in this case, the number of test cases will equal the cyclomatic complexity of the program.
