Badí‘

Badí‘ (Arabic: ﺑﺪﻳﻊ‎‎ 1852 – 1869) was the title of Mírzá Áqá Buzurg-i-Nishapuri, also known by the title the Pride of Martyrs. He was the son of `Abdu'l-Majid-i-Nishapuri, a follower of the Báb and Bahá'u'lláh.

Badí‘ is most famous for being the bearer of a tablet written by Bahá'u'lláh to Nasiri'd-Din Shah, for which he was tortured and killed at the age of 17. He is also one of the foremost Apostles of Bahá'u'lláh.

The Kitáb-i-Badí', a book written by Bahá'u'lláh, has no relation to the Badí‘ of this article.

Travels

Although Badí's father was a Bahá'í, Badí was originally not touched by the new religion. He was an unruly and rebellious youth, and his father described him as the "despair of the family". It was upon a meeting with Nabíl-i-A`zam that Badí‘ heard a poem by Bahá'u'lláh and began weeping. After finishing his studies, he gave away his possessions and set out on foot for Baghdad, where a significant number of Bahá'ís were under persecution. Finally he set out on foot from Mosul through Baghdad to the prison city of `Akka.

Banyan VINES

Banyan VINES was a computer network operating system and the set of computer network protocols it used to connect to client machines on the network. The name was an acronym for Virtual Integrated Network Service. Banyan Systems ran as a collection of services on top of AT&T UNIX System V, and based its core network protocols on the archetypical Xerox XNS stack. VINES was one of a group of XNS-based systems that also included Novell NetWare. It has since disappeared from the market, along with Banyan Systems.

James Allchin, who later worked as Group Vice President for Platforms at Microsoft Corporation until his retirement on January 30, 2007, was the chief architect of Banyan VINES.

VINES technology

VINES ran on a low-level protocol known as VIP—the VINES Internetwork Protocol—that was essentially identical to the lower layers of XNS. Addresses consisted of a 32-bit address and a 16-bit subnet that mapped to the 48-bit Ethernet address to route to machines. This meant that, like other XNS-based systems, VINES could only support a two-level internet.

HIStory: Past, Present and Future, Book I

HIStory: Past, Present and Future, Book I (usually shortened to HIStory) is the ninth overall studio album and his fifth under Epic Records by American recording artist Michael Jackson. It was released on June 16, 1995 by Epic Records. This is Jackson's first album on his own label, MJJ Productions, and consists of two discs: the first disc (HIStory Begins) is a compilation of some of his greatest hits from 1979 onward, while the second disc (HIStory Continues) is a studio album composed entirely of new material. The majority of the second disc's tracks were written and produced by Jackson, often in conjunction with collaborators.

HIStory was Jackson's return to releasing music following the accusation of child sexual abuse in August 1993. Many of the 15 songs pertain to the accusations and Jackson's mistreatment in the media, specifically the tabloids. The songs' themes include environmental awareness, isolation, greed, suicide and injustice.

HIStory is Jackson's most controversial album. Jackson was accused of using anti-Semitic lyrics in "They Don't Care About Us". Jackson stated that he did not mean any offense and on multiple occasions denied anti-Semitism. The dispute regarding the lyrics ended with Jackson re-recording them. R. Kelly was accused of plagiarizing one of the album's songs, "You Are Not Alone". In 2007 a judge ruled that the song was plagiarized and the song was subsequently banned from radio stations in Belgium.

Operation Sigma Sigma

The Sigma is an experimental glider developed in Britain from 1966 by a team led by Nicholas Goodhart. After disappointing performance during flight testing the Sigma was passed on to a Canadian group which carried out modifications, making the Sigma more competitive.

Design and development

Designed to compete in the 1970 World Championships, the team aimed to develop a wing that would climb well through a high lift coefficient and a large wing area, but equally had the "maximum possible reduction of area for cruise at low lift coefficients". At the same time for the minimum possible drag they aimed for "extensive" laminar flow. To achieve this they employed flaps that would alter both wing area and wing camber. Based on analysis of the nature of thermals encountered in cross-country flying, they reasoned that by having a slow turning circle, their sailplane could stay close to the central (and strongest) part of the thermal and gain maximum benefit.

Its unusual feature is its ability to vary its wing area using Fowler flaps. It had been tried before by the Hannover Akaflieg in 1938 with their AFH-4, the South African Beatty-Johl BJ-2 Assegai and the SZD Zefir gliders.

Sigma (cosmology)

Sigma in cosmology was a property of galaxies used when trying to work out the mystery of galaxies and their supermassive black holes.

History

In the late 1990s the NUKER experts had made observations with a spectroscope of two galaxies, one of an active galaxy with an active galactic nucleus called NGC10-68 and a dormant galaxy next door to us named Andromeda.

The observations are shown. The light from the centre in Andromeda galaxy was distorted proving the existence of super-massive black holes.

Other observations proved most galaxies had a similar centre whether it be active or dormant.

They then realised that the black holes must have something to do with a galaxy's formation, so they turned to something they thought was useless: the speed of the stars around the edge of the galaxy. This was Sigma, the speed of the stars at the edge of the galaxy supposedly unaffected by the mass of the black hole at the centre.

Usage In Cosmology

The NUKER team calculated the sigma of several stars in different galaxies and the mass of the black hole at the (nucleus) centre. They expected no correlation what so ever. But when plotting their results on a Scatter diagram and drawing a line of best fit they ended up with a positive correlation. It appeared that the heavier the black hole at the centre was the faster the stars within the galaxy travelled.

Sigma baryon

The Sigma baryons are a family of subatomic hadron particles which have a +2, +1 or −1 elementary charge or are neutral. They are baryons containing three quarks: two up and/or down quarks, and one third quark, which can be either a strange (symbols Σ+, Σ0, Σ−), a charm (symbols Σ++
c, Σ+
c, Σ0
c), a bottom (symbols Σ+
b, Σ0
b, Σ−
b) or a top (symbols Σ++
t, Σ+
t, Σ0
t) quark. However, the top Sigmas are not expected to be observed as the Standard Model predicts the mean lifetime of top quarks to be roughly 6975500000000000000♠5×10⁻²⁵ s. This is about 20 times shorter than the timescale for strong interactions, and therefore it does not form hadrons.

List

The symbols encountered in these lists are: I (isospin), J (total angular momentum), P (parity), u (up quark), d (down quark), s (strange quark), c (charm quark), t (top quark), b (bottom quark), Q (charge), B (baryon number), S (strangeness), C (charmness), B′ (bottomness), T (topness), as well as other subatomic particles (hover for name).

Kat (band)

Kat is a Polish heavy metal band formed in 1979 in Katowice, Poland. They have been accused, mainly by the Polish media, of promoting Satanism.

In Polish "kat" means executioner. KAT is one of the most important bands in Polish heavy metal overall, and is also mentioned as one of the main precursors of thrash and even black metal genres in this country. KAT's most famous album is Oddech wymarłych światów (The Breath of Extinct Worlds), considered an opus of Polish heavy metal.

The band is best known for tracks "Czas zemsty" (Time of revenge), "Łza dla cieniów minionych" (A tear for the shadows gone), "Wyrocznia" (Oracle) and "Noce Szatana " (The nights of Satan).

Band history

KAT was founded in 1979 by guitarist Piotr Luczyk and drummer Ireneusz Loth. Shortly after they were joined by bassist Tomasz Jaguś and another guitarist, Ryszard Pisarski. They played instrumental music influenced by hard rock bands, mainly Deep Purple, Led Zeppelin, and Black Sabbath. In 1981, during the first edition of the Silesian Rock festival, the band found a singer, Roman Kostrzewski The line-up was filled out by guitarist Wojciech Mrowiec and in 1984 KAT released the debut single "Noce szatana / Ostatni tabor" (Polish for The Nights of Satan / The Last Train). Robert "Lor" Milewski wrote the lyrics of both songs; since then Kostrzewski became the lyricist, incorporating poetry, Polish folklore, and mysticism. The band also toured with Hanoi Rocks.
