Wisdom is a wild female Laysan albatross. She is the oldest confirmed wild bird in the world as well as the oldest banded bird in the world.

Stigler's law of eponymy, proposed by University of Chicago statistics professor Stephen Stigler in his 1980 publication Stigler’s law of eponymy, states that no scientific discovery is named after its original discoverer. Examples include Hubble's law, which was derived by Georges Lemaître two years before Edwin Hubble, the Pythagorean theorem, which was known to Babylonian mathematicians before Pythagoras, and Halley's Comet, which was observed by astronomers since at least 240 BC (although its official designation is due to the first ever mathematical prediction of such astronomical phenomenon in the sky, not to its discovery). Stigler himself named the sociologist Robert K. Merton as the discoverer of "Stigler's law" to show that it follows its own decree, though the phenomenon had previously been noted by others.

Slow-scan television (SSTV) is a picture transmission method, used mainly by amateur radio operators, to transmit and receive static pictures via radio in monochrome or color.

A literal term for SSTV is narrowband television. Analog broadcast television requires at least 6 MHz wide channels, because it transmits 25 or 30 picture frames per second (see ITU analog broadcast standards), but SSTV usually only takes up to a maximum of 3 kHz of bandwidth. It is a much slower method of still picture transmission, usually taking from about eight seconds to a couple of minutes, depending on the mode used, to transmit one image frame.

Since SSTV systems operate on voice frequencies, amateurs use it on shortwave (also known as HF by amateur radio operators), VHF and UHF radio.

Edwin Ray Guthrie (; January 9, 1886 in Lincoln, Nebraska – April 23, 1959 in Seattle, Washington) was a behavioral psychologist. He first worked as a mathematics teacher, and philosopher, but switched to psychology when he was 33. He spent most of his career at the University of Washington, where he became full professor and then emeritus professor in psychology.

Guthrie is best known for his theory that all learning was based on a stimulus–response association. This was variously described as one trial theory, non-reinforcement, and contiguity learning. The theory was:

"A combination of stimuli which has accompanied a movement will on its recurrence tend to be followed by that movement".

One word that his coworkers and students used to describe Guthrie and his theories was "simple", and perhaps he did prefer to use simple terms to illustrate complex ideas. However, "It is undoubtedly true that many reviews of Guthrie in the literature have mistaken incompleteness for simplicity".

His simple nature carried into his teachings where he took great pride in working with and teaching students.

The ASUS Eee PC is a netbook computer line from Asus, and a part of the ASUS Eee product family. At the time of its introduction in late 2007, it was noted for its combination of a lightweight, Linux-based operating system, solid-state drive (SSD), and relatively low cost. Newer models added the options of Microsoft Windows operating system and rotating media hard disk drives (HDD), and initially retailed for up to 500 euros.

The first Eee PC was a milestone in the personal computer business, launching the netbook category of small, low-cost laptops in the West (in Japan, subnotebooks had long been a staple in computing). According to Asus, the name Eee derives from "the three Es", an abbreviation of its advertising slogan for the device: "Easy to learn, Easy to work, Easy to play".

In January 2013, ASUS officially ended production of their Eee PC series, citing declining sales due to consumers favoring tablets and Ultrabooks over netbooks. However, they subsequently restarted the line with the release of the EeeBook series in 2015.

Alcohol powder or powdered alcohol or dry alcohol is a product generally made using micro-encapsulation. When reconstituted with water, alcohol (specifically ethanol) in powder form becomes an alcoholic drink. In March 2015 four product labels for specific powdered alcohol products were approved by the United States Alcohol and Tobacco Tax and Trade Bureau (TTB) which opened the doors for legal product sales. However, as of 4 January 2016, the product is not yet available for sale and legalization remains controversial due to public-health and other concerns. Researchers have expressed concern that, should the product go into production, increases in alcohol misuse, abuse, and associated physical harm to its consumers could occur above what has been historically associated with liquid alcohol alone.

On 25 May 2003, a Boeing 727, registered N844AA, was stolen at Quatro de Fevereiro Airport, Luanda, Angola. Its disappearance prompted a worldwide search by the United States' Federal Bureau of Investigation (FBI) and Central Intelligence Agency (CIA). No trace of the aircraft has since been found.

Old Elbe Tunnel or St. Pauli Elbe Tunnel (German: Alter Elbtunnel colloquially or St. Pauli Elbtunnel officially) which opened in 1911, is a pedestrian and vehicle tunnel in Hamburg. The 426 m (1,398 ft) long tunnel was a technical sensation; 24 m (80 ft) beneath the surface, two 6 m (20 ft) diameter tubes connect central Hamburg with the docks and shipyards on the south side of the river Elbe. This was a big improvement for tens of thousands of workers in one of the busiest harbors in the world.

Six large lifts on either side of the tunnel carry pedestrians and vehicles to the bottom. The two tunnels are both still in operation, though due to their limited capacity by today's standards, other bridges and tunnels have been built and taken over most of the traffic.

In 2008 approximately 300,000 cars, 63,000 bicycles, and 700,000 pedestrians used the tunnel. The tunnel is opened 24 hours for pedestrians and bicycles. For motorized vehicles, opening times are currently Monday to Friday from 5:20 a.m. to 8:00 p.m. and on Saturdays from 5:20 a.m. to 4:00 p.m.

"Belling the Cat" is a fable also known under the titles "The Bell and the Cat" and "The Mice in Council". Although often attributed to Aesop, it was not recorded before the Middle Ages and has been confused with the quite different fable of Classical origin titled The Cat and the Mice. In the classificatory system established for the fables by B. E. Perry, it is numbered 613, which is reserved for Mediaeval attributions outside the Aesopic canon.
