In aesthetics, the uncanny valley is a hypothesized relationship between the degree of an object's resemblance to a human being and the emotional response to such an object. The concept of the uncanny valley suggests that humanoid objects which imperfectly resemble actual human beings provoke uncanny or strangely familiar feelings of eeriness and revulsion in observers. "Valley" denotes a dip in the human observer's affinity for the replica, a relation that otherwise increases with the replica's human likeness.

Examples can be found in robotics, 3D computer animations, and lifelike dolls among others. With the increasing prevalence of virtual reality, augmented reality, and photorealistic computer animation, the "valley" has been cited in the popular press in reaction to the verisimilitude of the creation as it approaches indistinguishability from reality. The uncanny valley hypothesis predicts that an entity appearing almost human will risk eliciting cold, eerie feelings in viewers.

The National Raisin Reserve was a raisin reserve of the United States. It was created after World War II by the government in order to control raisin prices. The reserve was run by the Raisin Administrative Committee. It was enforced by means of a "marketing order". In 2015, the United States Supreme Court ruled the reserve unconstitutional and ended it.

Brandolini's law, also known as the bullshit asymmetry principle, is an internet adage which emphasizes the difficulty of debunking bullshit: "The amount of energy needed to refute bullshit is an order of magnitude bigger than to produce it."

The Invincible (Polish: Niezwyciężony) is a hard science fiction novel by Polish writer Stanisław Lem, published in 1964.

The Invincible originally appeared as the title story in Lem's collection Niezwyciężony i inne opowiadania ("The Invincible and Other Stories"). A translation into German was published in 1967; an English translation by Wendayne Ackerman, based on the German one, was published in 1973. A direct translation into English from Polish, by Bill Johnston, was published in 2006.

It was one of the first novels to explore the ideas of microrobots/smartdust/etc., artificial swarm intelligence and "necroevolution", a term suggested by Lem for evolution of non-living matter.

Karoshi (過労死, Karōshi), which can be translated literally as "overwork death" in Japanese, is occupational sudden mortality. The major medical causes of karoshi deaths are heart attack and stroke due to stress and a starvation diet. This phenomenon is also widespread in other parts of Asia.

The master suppression techniques is a framework articulated in 1945 by the Norwegian psychologist and philosopher Ingjald Nissen. These techniques identified by Nissen are ways to indirectly suppress and humiliate opponents. In the late 1970s, the framework was popularized by Norwegian social psychologist Berit Ås, who reduced Nissen's original nine means to five, and claimed this was a technique mostly used in the workplace by men against women. Master suppression techniques are defined as strategies of social manipulation by which a dominant group maintains such a position in an (established or unexposed) hierarchy. They are very prominent in Scandinavian scholarly and public debate, where the expression is also used to refer to types of social manipulation not part of Ås's framework. Master suppression techniques are sometimes called domination techniques.

A gyrocar is a two-wheeled automobile. The difference between a bicycle or motorcycle and a gyrocar is that in a bike, dynamic balance is provided by the rider, and in some cases by the geometry and mass distribution of the bike itself, and the gyroscopic effects from the wheels. Steering a motorcycle is done by precessing the front wheel. In a gyrocar, balance was provided by one or more gyroscopes, and in one example, connected to two pendulums by a rack and pinion.

The concept was originally described in fiction in 1911 "Two Boys in a Gyrocar: The story of a New York to Paris Motor Race" by Kenneth Brown, (Houghton Mifflin Co). However the first prototype Gyrocar, The Shilovski Gyrocar, was commissioned in 1912 by the Russian Count Pyotr Shilovsky, a lawyer and member of the Russian royal family. It was manufactured to his design by the Wolseley Tool and Motorcar Company in 1914 and demonstrated in London the same year. The gyrocar was powered by a modified Wolseley C5 engine of 16–20 hp, with a bore of 90 mm and a stroke of 121 mm. It was mounted ahead of the radiator, driving the rear wheel through a conventional clutch and gear box. A transmission brake was fitted after the gearbox – there were no brakes on the wheels themselves. The weight of the vehicle was 2.75 tons and it had a very large turning radius.

In 1927 Louis Brennan, funded to the tune of £12,000 (plus a £2000 per year) by John Cortauld built a rather more successful gyrocar. Two contra-rotating gyros were housed under the front seats, spun in a horizontal plane at 3500 rpm by 24V electric motors powered from standard car batteries. This was the greatest speed obtainable with the electric motors available, and meant that each rotor had to weigh 200 lb (91 kg) to generate sufficient forces. Precession was in the vertical fore-aft plane. The car had a Morris Oxford engine, engine mountings, and gearbox. Two sidewheels (light aircraft tailwheels were used) were manually lowered on stopping; if the driver forgot and switched off the gyros and walked away, the car would continue to balance itself using the gyro momentum for a few minutes, and then the wheels would automatically be dropped to stop tipping.

Lanai (Hawaiian: Lānaʻi, Hawaiian: [laːˈnɐʔi, naːˈnɐʔi], lə-NY, lah-NAH-ee, also US: lah-NY, lə-NAH-ee,) is the sixth-largest of the Hawaiian Islands and the smallest publicly accessible inhabited island in the chain. It is colloquially known as the Pineapple Island because of its past as an island-wide pineapple plantation. The island's only settlement of note is the small town of Lanai City. As of 2012, the island is 98% owned by Larry Ellison, cofounder and chairman of Oracle Corporation; the remaining 2% is owned by the state of Hawaii or individual homeowners.

Lanai is a roughly apostrophe-shaped island with a width of 18 miles (29 km) in the longest direction. The land area is 140.5 square miles (364 km²), making it the 43rd largest island in the United States. It is separated from the island of Molokaʻi by the Kalohi Channel to the north, and from Maui by the Auʻau Channel to the east. The United States Census Bureau defines Lanai as Census Tract 316 of Maui County. Its total population rose to 3,367 as of the 2020 United States census, up from 3,193 as of the 2000 census and 3,131 as of the 2010 census. As visible via satellite imagery, many of the island's landmarks are accessible only by dirt roads that require a four-wheel drive vehicle due to the lack of paved roadways.

There is one school, Lanai High and Elementary School, serving the entire island from kindergarten through 12th grade. There is also one hospital, Lanai Community Hospital, with 24 beds, and a community health center providing primary care, dental, behavioral health and selected specialty services in Lanai City. There are no traffic lights on the island.
