Cluster (spacecraft)

Cluster was a constellation of four European Space Agency spacecraft which were launched on the maiden flight of the Ariane 5 rocket, Flight 501, and subsequently lost when that rocket failed to achieve orbit. The launch, which took place on Tuesday, 4 June 1996, ended in failure due to an error in the software design caused by assertions having been turned off, which in turn caused inadequate protection from integer overflow. This resulted in the rocket veering off its flight path 37 seconds after launch, beginning to disintegrate under high aerodynamic forces, and finally self-destructing by its automated flight termination system. The failure has become known as one of the most infamous and expensive software bugs in history. The failure resulted in a loss of more than US$370 million.

Cluster (novels)

Cluster is a series of science fiction novels by Piers Anthony. Anthony originally conceived of and wrote the series as a trilogy but later added two additional volumes.

Cluster (album)

Cluster is the eponymous debut studio album by German electronic music outfit Cluster. It was recorded in 1971 and released the same year by record label Philips. It is also the only album on which Conrad Plank is credited as a member.

Cluster (physics)

In physics, the term clusters denotes small, multiatom particles. As a rule of thumb, any particle of somewhere between 3 and 3×10 atoms is considered a cluster. Two-atom particles are sometimes considered clusters as well.. It can be noted that a two atom particle may also be a molecule.

The term can also refer to the organization of protons and neutrons within an atomic nucleus, e.g. the Alpha particle (also known as "α-cluster"), consisting of two protons and two neutrons (as in a helium nucleus).

Although first reports of cluster species date back already to the 1940s, Cluster science emerged as a separate direction of research in the 1980s, One purpose of the research was to study the gradual development of collective phenomena which characterize a bulk solid. These are for example the color of a body, its electrical conductivity, its ability to absorb or reflect light, and magnetic phenomena such as ferro-, ferri-, or antiferromagnetism. These are typical collective phenomena which only develop in an aggregate of a large number of atoms.

It was found that collective phenomena break down for very small cluster sizes. It turned out, for example, that small clusters of a ferromagnetic material are super-paramagnetic rather than ferromagnetic. Paramagnetism is not a collective phenomenon, which means that the ferromagnetism of the macrostate was not conserved by going into the nanostate. The question then was asked for example, “How many atoms do we need in order to obtain the collective metallic or magnetic properties of a solid?” Soon after the first cluster sources had been developed in 1980, an ever larger community of cluster scientists was involved in such studies.

This development led to the discovery of fullerenes in 1986 and carbon nanotubes a few years later.

In science, a lot is known about properties of the gas phase; however, comparatively little is known about the condensed phases (the liquid phase and solid phase.) The study of clusters attempts to bridge this gap of knowledge by clustering atoms together and studying their characteristics. If enough atoms were clustered together, eventually one would obtain a liquid or solid.

The study of atomic and molecular clusters also benefits the developing field of nanotechnology. If new materials are to be made out of nanoscale particles, such as nanocatalysts and quantum computers, the properties of the nanoscale particles (the clusters) must first be understood.

Cluster (band)

Cluster was a German experimental musical group consisting of Hans-Joachim Roedelius and Dieter Moebius. They have recorded albums in a wide variety of styles ranging from experimental music to progressive rock and have influenced the development of contemporary popular electronic and ambient music. Cluster was active from 1971 until 2010, releasing a total of 15 albums, including two collaborations with Brian Eno. Musician, writer and rock historian Julian Cope places three Cluster albums in his Krautrock Top 50 and "The Wire" places Cluster's debut album "Cluster '71" in their "One Hundred Records That Set The World On Fire".

After a decade long hiatus Cluster reunited in April, 2007. They performed at the opening of documenta 12, a major exhibition of modern and contemporary art held every five years in Kassel, Germany on June 15, 2007. In late 2007 Cluster performed at concerts across Europe and played the United States in 2008 for the first time since 1996.

Cluster disbanded at the end of 2010. Their final concert was on December 5 of that year. In 2011, Roedelius recruited Onnen Bock to reactivate Cluster under the name of "Qluster". Their debut release came in the form of a trilogy entitled Rufen - Fragen - Antworten (Calling - Questioning - Responding), containing a piano record, a live documentary and a normal record. In January 2013, Qluster released their fourth record Lauschen (Eavesdropping), a live record with world musician Armin Metz.
