A world record is usually the best global performance ever recorded and officially verified in a specific skill or sport. The book Guinness World Records collates and publishes notable records of all types, from first and best to worst human achievements, to extremes in the natural world and beyond. The website RecordSetter has begun to take on the same territory, but with a more inclusive policy, as users submit videos of record attempts in order to try to receive a world record. The website challengers.guinnessworldrecords.com is similar to RecordSetter, as the record attempts are judged by Guinness World Records adjudicators, but the records to attempt are provided beforehand.

Terminology

In the United States the form World's Record was formerly more common. The term World Best was also briefly in use. The latter term is still used in athletics events, including track and field and road running) to describe good and bad performances not recognized as an official world record: either because the event is a non-qualifying event (e.g. the 150 m run or individual events in a decathlon), or because it does not fulfil other criteria of an otherwise qualifying event (e.g. the Great North Run half-marathon, which has an excessive downhill gradient). The term is also used in video game speedrunning when someone achieves the fastest possible time for the game and category.

Record A.E.B.E. (brand also spelled in Greek as Ρεκόρ) was the name of a Greek company producing agricultural machinery and vehicles, founded in Heraklion, Crete in 1957 and dissolved in 1999.

Its products have included walking tractors (since 1958), a family of characteristic Greek three-wheel vehicles combining truck and tractor functions (since 1966), "proper" tractors (since 1970) and four-wheel trucks (since 1978); mechanical equipment like clutches and gearboxes for use in its vehicles were also produced. Its main market was Greece, although some of its walking tractors were also exported. Annual vehicle production in the late 1970s and early 1980s averaged 500 units.

The most advanced models were the 1970 ΓΣ 7 tractor, which used 18-26 hp Ruggerini Diesel engines, and the 1980 GS 2000 truck, which used a 1,400 cc, 55 hp Peugeot Diesel engine. This fibreglass-bodied truck could carry two tonnes and featured a cab design clearly influenced by those of contemporary Japanese models, in particular the first generation Mitsubishi Delica.

The archaeological record is the body of physical (i.e. not written) evidence about the past. It is one of the core concepts in archaeology, the academic discipline concerned with documenting and interpreting the archaeological record.Archaeological theory is used to interpret the archaeological record for a better understanding of human cultures. The archaeological record can consist of the earliest ancient findings as well as contemporary artifacts. Human activity has had a large impact on the archaeological record. Destructive human processes such as agriculture and land development may damage or destroy potential archaeological sites. Other threats to the archaeological record include natural phenomena and scavenging. Archaeology is a destructive science and can take away from the finite resources of the archaeological record. It is for this reason that archaeologists limit the amount of excavation that they do at each site and meticulous records are kept of what is found. The archaeological record is the record of our human history, of why our civilizations prosper or fail, why our cultures change and grow. It is the story of this world we humans have created.

Bleach is the debut studio album by American rock band Nirvana, released on June 15, 1989 by Sub Pop. The main recording sessions took place at Reciprocal Recording in Seattle, Washington between December 1988 and January 1989.

Bleach was well received by critics, but failed to chart in the U.S. upon its original release. The album was re-released internationally by Geffen Records in 1992 following the success of Nirvana's second album, Nevermind (1991). The re-release debuted at number 89 on the Billboard 200, and peaked at number 33 on the UK Albums Chart and 34 on the Australian albums chart. In 2009 Sub Pop released a 20th anniversary edition of Bleach featuring a live recording of a Nirvana show in Portland, Oregon from 1990 as extra material. Since its release in 1989, Bleach has sold over 1.7 million units in the United States alone. It is Sub Pop's best-selling release to date.

Recording

Following the release of its debut single "Love Buzz" on Sub Pop in November 1988, Nirvana practiced for two to three weeks in preparation for recording a full-length album, even though Sub Pop had only requested an EP. The main sessions for Bleach took place at Reciprocal Recording Studios in Seattle, with local producer Jack Endino.

In biology, any group of fish that stay together for social reasons are shoaling (pronounced /ˈʃoʊlɪŋ/), and if the group is swimming in the same direction in a coordinated manner, they are schooling (pronounced /ˈskuːlɪŋ/). In common usage, the terms are sometimes used rather loosely. About one quarter of fish species shoal all their lives, and about one half shoal for part of their lives.

Fish derive many benefits from shoaling behaviour including defence against predators (through better predator detection and by diluting the chance of individual capture), enhanced foraging success, and higher success in finding a mate. It is also likely that fish benefit from shoal membership through increased hydrodynamic efficiency.

Fish use many traits to choose shoalmates. Generally they prefer larger shoals, shoalmates of their own species, shoalmates similar in size and appearance to themselves, healthy fish, and kin (when recognized).

The "oddity effect" posits that any shoal member that stands out in appearance will be preferentially targeted by predators. This may explain why fish prefer to shoal with individuals that resemble themselves. The oddity effect would thus tend to homogenize shoals.
