A maritime incident occurred on 13 February 1997 when a rogue wave struck the German-registered container ship Tokio Express off the coast of Land's End, Cornwall, United Kingdom, causing 62 containers to fall overboard. One container held approximately 4.8 million Lego pieces, primarily from sea-themed sets such as Lego Aquazone and Lego Pirates. The spilled pieces have washed ashore on coastlines across the UK, Ireland, the Netherlands, and as far as Australia, becoming a cultural phenomenon and an unintentional case study in ocean currents and marine plastic pollution.

The Howard Dean scream incident, commonly known as the Dean scream speech, was an energetic scream by Howard Dean, the former governor of Vermont, on January 19, 2004, during a speech he gave at the Val-Air Ballroom in West Des Moines, Iowa. That night, the presidential candidate had just lost the Iowa caucus to John Kerry and wanted to reassure his supporters. He listed states he would win to a raucous audience before screaming "BYAH!" Within four days, it was broadcast 633 times on national news networks and cable channels.

Following the scream, Dean lost more primaries and suspended his campaign following his third-place result in Wisconsin. Some commentators have described the speech as a political gaffe that destroyed Dean's campaign; however, Dean and his campaign staff have claimed that he would have lost anyway, due to poor campaign organization. Additionally, Christine Pelosi, Pacific Standard, and historian Robert Thompson have all claimed that Dean's probability of being nominated was already low due to a lack of party insider support, the Iowa loss, and the media's previous painting of Dean as too hot-tempered for the presidency.

In Marxist theory, the Lumpenproletariat (German: [ˈlʊmpn̩pʁoletaʁi̯ˌaːt] ; ) is the underclass devoid of class consciousness. Karl Marx and Friedrich Engels coined the word in the 1840s and used it to refer to the unthinking lower strata of society exploited by reactionary and counter-revolutionary forces, particularly in the context of the revolutions of 1848. They dismissed the revolutionary potential of the Lumpenproletariat and contrasted it with the proletariat. Among other groups, criminals, vagabonds, and prostitutes are usually included in this category.

The Social Democratic Party of Germany made wide use of the term by the turn of the 20th century. Vladimir Lenin and Leon Trotsky followed Marx's arguments and dismissed the group's revolutionary potential, while Mao Zedong argued that proper leadership could harness it. The word Lumpenproletariat, popularized in the West by Frantz Fanon's The Wretched of the Earth in the 1960s, has been adopted as a sociological term. However, what some consider to be its vagueness and its history as a term of abuse has led to some criticism. Some revolutionary groups, most notably the Black Panther Party and the Young Lords, have sought to mobilize the Lumpenproletariat.

The Shell Grotto, sometimes called the Shell Temple, is an ornate underground shell grotto in the seaside town of Margate, Kent, England. The grotto, which has a passageway and main room, was dug out from chalk, a soft limestone common in the region. Almost all the surface area of the walls and roof is covered in mosaics created entirely of seashells, totalling about 2,000 square feet (190 m²) of mosaic, with approximately 4.6 million shells. Its age, creators, and purpose are unknown, which has inspired a wide range of speculation, although several other shell grottos in England were made in the 18th century. This grotto was rediscovered in about 1835 and first opened to the public as a privately-owned tourist attraction in 1837. The grotto is a Grade I-listed building and remains open to the public. Attached to the grotto is a modern museum room, cafe, and gift shop.

Lee Felsenstein (born April 27, 1945) is an American computer engineer who played a central role in the development of personal computers. He was one of the original members of the Homebrew Computer Club and the designer of the Osborne 1, the first mass-produced portable computer.

Before the Osborne, Felsenstein designed the Intel 8080 based Sol-20 computer from Processor Technology, the PennyWhistle modem, and other early "S-100 bus" era designs. His shared-memory alphanumeric video display design, the Processor Technology VDM-1 video display module board, was widely copied and became the basis for the standard display architecture of personal computers.

Many of his designs were leaders in reducing costs of computer technologies for the purpose of making them available to large markets. His work featured a concern for the social impact of technology and was influenced by the philosophy of Ivan Illich. Felsenstein was the engineer for the Community Memory project, one of the earliest attempts to place networked computer terminals in public places to facilitate social interactions among individuals, in the era before the commercial Internet.

A glass knife is a knife with a blade made of glass, with a fracture line forming an extremely sharp cutting edge.

Glass knives were used in antiquity due to their natural sharpness and the ease with which they could be manufactured. In modern electron microscopy glass knives are used to make the ultrathin sections needed for imaging.

SETL (SET Language) is a very high-level programming language based on the mathematical theory of sets. It was originally developed at the New York University (NYU) Courant Institute of Mathematical Sciences in the late 1960s, by a group including (Jack) Jacob T. Schwartz, R.B.K. Dewar, and E. Schonberg. Schwartz is credited with designing the language.

Ondol (ON-dol; , Korean: 온돌; Hanja: 溫突/溫堗; Korean pronunciation: [on.dol]) or gudeul (구들; [ku.dɯl]) in Korean traditional architecture is underfloor heating that uses direct heat transfer from wood smoke to heat the underside of a thick masonry floor. In modern usage, it refers to any type of underfloor heating, or to a hotel or a sleeping room in Korean (as opposed to Western) style.

The main components of the traditional ondol are an agungi (아궁이; [a.guŋ.i]), a firebox or stove, accessible from an adjoining room (typically kitchen or master bedroom), a raised masonry floor underlain by horizontal smoke passages, and a vertical, freestanding chimney on the opposite exterior wall providing a draft. The heated floor, supported by stone piers or baffles to distribute the smoke, is covered by stone slabs, clay and an impervious layer such as oiled paper.

Bertie the Brain is one of the first games developed during the early history of video games. It was built in Toronto by Josef Kates for the 1950 Canadian National Exhibition. The four meter (13 foot) tall computer allowed exhibition attendees to play a game of tic-tac-toe against an algorithm, presented by its creators as artificial intelligence. The player entered a move on a keypad in the form of a three-by-three grid, and the game played out on a grid of lights overhead. The machine had an adjustable difficulty level. After two weeks on display by Rogers Majestic, the machine was disassembled at the end of the exhibition and largely forgotten as a curiosity.

Kates built the game to showcase his additron tube, a miniature version of the vacuum tube, though the transistor overtook it in computer development shortly thereafter. Patent issues prevented the additron tube from being used in computers besides Bertie before it was no longer useful. Bertie the Brain is a candidate for the first video game, as it was potentially the first computer game to have any sort of visual display of the game. It appeared only three years after the 1947 invention of the cathode-ray tube amusement device, the earliest known interactive electronic game to use an electronic display. Bertie's use of light bulbs rather than a screen with real-time visual graphics, however, much less moving graphics, does not meet some definitions of a video game.

John Titor (May 5, 6 or 7, 1998) is a name used on several bulletin boards during 2000 and 2001 by a poster claiming to be an American military time traveler from 2036. Titor made numerous vague and specific predictions regarding calamitous events in 2004 and beyond, including a nuclear war, none of which came true. Subsequent closer examination of Titor's assertions provoked widespread skepticism. Inconsistencies in his explanations, the uniform inaccuracy of his predictions, and a private investigator's findings all led to the general impression that the entire episode was an elaborate hoax. A 2009 investigation concluded that Titor was likely the creation of Larry Haber, a Florida entertainment lawyer, along with his brother Morey, a computer scientist.
