Ealdgyth (wife of Edmund Ironside)

Ealdgyth (circa 992 – after 1016), modern English Edith may have been the name of the wife of Sigeferth son of Earngrim, thegn of the Seven Burghs, and later of King Edmund Ironside. She was probably the mother of Edmund's sons Edward the Exile and Edmund Ætheling.

The Anglo-Saxon Chronicle records that Sigeferth and his brother Morcar, described as "foremost thegns of the Seven Burghs" were killed at an assembly of the English nobility at Oxford. Ealdorman Eadric Streona is said to have killed them "dishonourably" after having invited them to his rooms. The Seven Burghs, otherwise unknown, are presumed to have been the Five Burghs and Torksey and York. Following the killings, King Æthelred the Unready had the property of Sigeferth and Morcar seized and ordered that Sigeferth's widow, whose name the Chronicle does not record, should be detained at Malmesbury Abbey. The chronicle of John of Worcester calls her Ealdgyth.In the late summer of 1015, at some time between 15 August and 8 September, Edmund Ironside raised a revolt against his father King Æthelred. Either then, or perhaps even earlier, he removed Sigeferth's widow from Malmesbury, against his father's wishes, and married her. Sigeferth and Morcar's friends and allies supported Edmund after this. While two charters issued by Edmund which mention his wife survive from about this time, neither of them contain her name in the surviving texts.It is generally, but not universally, supposed that Ealdgyth, if that was her name, was the mother of Edmund Ironside's sons. These were Edmund, who died young in exile, and Edward the Exile, who returned to England late in the reign of his uncle King Edward the Confessor and died soon afterwards. Whether she went into exile with her children following Edmund's death in 1016 is unknown.

One reason advanced for supposing that John of Worcester may have been mistaken in naming this woman Ealdgyth is that Sigeferth's brother Morcar had also been married to a woman named Ealdgyth. This Ealdgyth was the daughter of Ælfthryth, and niece of Ælfhelm, Ealdorman of York and Wulfric Spot. While Ealdgyth is a common female name in the period, this coincidence has raised the suspicion that the Worcester chronicler has confused Sigeferth's widow with his sister-in-law.

Gavril Radomir of Bulgaria

Gavril Radomir (Bulgarian: Гаврил Радомир, Greek: Γαβριὴλ Ρωμανός/Gavriil Romanos, anglicized as "Gabriel Radomir") was the emperor (tsar) of Bulgaria from October 1014 to August or September 1015. He was the son of tsar Samuel (r. 997–1014).

German submarine U-1015

German submarine U-1015 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.

She was ordered on 23 March 1942, and was laid down on 5 April 1943, at Blohm & Voss, Hamburg, as yard number 215. She was launched on 7 February 1944, and commissioned under the command of Oberleutnant zur See Hans-Heinz Boos on 23 March 1944.

Haakon Ericsson

Haakon Ericsson (Old Norse: Hákon Eiríksson, Norwegian: Håkon Eiriksson; died c. 1029-1030) was Earl of Lade and governor of Norway as a vassal under Knut the Great.

Håkon Eiriksson was from a dynasty of Norwegian rulers in the eastern part of Trondheim, bordering the Trondheimsfjord. He was the son of Eirik Håkonson, ruler of Norway and earl of Northumbria. His mother is commonly believed to have been Gytha, a daughter of Sweyn Forkbeard and Sigrid the Haughty of Denmark and half-sister of King Knut. After the Battle of Svolder, Eirik Håkonson, with his brother Sveinn Hákonarson, became kings of Norway under Sweyn Forkbeard. In 1014 or 1015 Eirik Håkonson left Norway and joined Knut for his campaign in England. The north English earldom of Northumbria was given by Knut to Eirik after he won control of the north. Eirik remained as earl of Northumbria until his death between 1023 and 1033.

As his father's successor in Norway, Håkon Eiriksson ruled as a Danish vassal from 1012 to 1015, with Einar Tambarskjelve as his aide and his uncle, Sveinn Hákonarson, holding some areas as a Swedish vassal. After some years' absence in England fighting the Danes, Olaf Haraldsson returned to Norway in 1015 and declared himself king, obtaining the support of the petty kings of the Uplands. In 1016, Olaf defeated Sveinn Hákonarson at the Battle of Nesjar. After the victory of Olaf Haraldsson, Håkon fled to England where he was well received by King Knut and made Earl of Worcester. After the Battle of the Helgeå, Norwegian nobles rallied behind Knut.

He is recorded as being the ruler of the Sudreyar from 1016 until 1030. In 1028, Håkon Eiriksson returned as Knut's vassal ruler of Norway.

Håkon died in a shipwreck in the Pentland Firth, between the Orkney Islands and the Scottish mainland, in either late 1029 or early 1030.


The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (103 Hz, kHz), megahertz (106 Hz, MHz), gigahertz (109 Hz, GHz), terahertz (1012 Hz, THz), petahertz (1015 Hz, PHz), and exahertz (1018 Hz, EHz).

Some of the unit's most common uses are in the description of sine waves and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the speeds at which computers and other electronics are driven.

KJHM (101.5 MHz) is a commercial FM radio station licensed to Watkins, Colorado, and serving the Denver metropolitan area. It is owned by Max Media and airs a Rhythmic Oldies format branded as Jammin' 101.5. Its studios are located on Parker Road in Aurora.

KJHM has an effective radiated power (ERP) of 93,000 watts at 600 meters (2051 feet) in height above average terrain (HAAT). The tower is about 60 miles northeast of Denver near Leader, shared with sister station 107.1 KFCO. KJHM's signal isn't as strong in Downtown Denver, or in the western suburbs (Arvada, Lakewood, and Wheat Ridge). But there is a 20,000 watt booster station in Commerce City, 101.5 KJHM-1-FM, which helps the signal reach closer to Denver.

Masawaih al-Mardini

Masawaih al-Mardini (Yahyā ibn Masawaih al-Mardini; known as Mesue the Younger) was a Syrian physician. He was born in Mardin, Upper Mesopotamia. After working in Baghdad, he entered to the service of the Fatimid caliph Al-Hakim bi-Amr Allah. He died in 1015 in Cairo at the age of ninety.Masawaih al-Mardini was a Nestorian Christian. He is known due to his books on purgatives and emetics (De medicins laxativis) and on the complete pharmacopoeia in 12 parts called the Antidotarium sive Grabadin medicamentorum, which remained for centuries the standard textbook of pharmacy in the West.He also described methods of distillation of empyreumatic oils. A method of extracting oil from "some kind of bituminous shale", one of the first descriptions of extraction of shale oil was described by him in the 10th century.

Michael V Kalaphates

NGC 1015

NGC 1015 is a barred spiral galaxy, at a distance of 118 million light years in the constellation of Cetus (The Whale).


Peta () is a decimal unit prefix in the metric system denoting multiplication by 1015 (1000000000000000). It was adopted as an SI prefix in the International System of Units in 1975, and has the symbol P.

Peta is derived from the Greek πέντε, meaning "five". It denotes the fifth power of 1000 (10005). It is similar to the prefix penta ("five"), but without the letter n (on the analogy of the prefix tera [from the Greek for "monster"] for 10004 looking like tetra- ["four"] with a letter missing).


1 petametre = 1015 metres

1 petasecond = 1015 seconds (31.7 million years)

1 petahertz = 1015 cycle per second. Visible light is around 0.5 PHz.

1 petabyte = 1015 bytes

the mass–energy equivalence is 89.9 PJ/kg

1 light-year = 9.461 Pm

Robert Guiscard

Robert Guiscard (, Modern French: [ɡiskaʁ]; c. 1015 – 17 July 1085) was a Norman adventurer remembered for the conquest of southern Italy and Sicily. Robert was born into the Hauteville family in Normandy, went on to become Count of Apulia and Calabria (1057–1059), and then Duke of Apulia and Calabria and Duke of Sicily (1059–1085), and briefly Prince of Benevento (1078–1081) before returning the title to the Pope.

His sobriquet, in contemporary Latin Viscardus and Old French Viscart, is often rendered "the Resourceful", "the Cunning", "the Wily", "the Fox", or "the Weasel". In Italian sources he is often Roberto il Guiscardo or Roberto d'Altavilla (from Robert de Hauteville).

Sweet onion

A sweet onion is a variety of onion that is not pungent. Their mildness is attributable to their low sulfur content and high water content when compared to other onion varieties.

Tau2 Arietis

Tau2 Arietis, Latinized from τ2 Arietis, is the Bayer designation for a binary star in the northern constellation on Aries. The combined apparent visual magnitude of this system is +5.09, which is bright enough to be seen with the naked eye. With an annual parallax shift of 10.27 mas, it is located at a distance of approximately 320 light-years (98 parsecs) from Earth, give or take a 20 light-year margin of error. At this distance the brightness of the star is diminished by 0.18 in magnitude because of extinction from interstellar gas and dust.The primary component is an evolved giant star with a stellar classification of K3 III. It has expanded to 19 times the radius of the Sun, from which it is radiating 120 times the Sun's luminosity. This energy is being emitted into outer space from the outer atmosphere at an effective temperature of 4,406 K, giving it the cool orange glow of a K-type star. At an angular separation of 0.53 arcseconds is a magnitude 8.50 companion.

United Nations Security Council Resolution 1015

United Nations Security Council resolution 1015, adopted unanimously on 15 September 1995, after reaffirming all resolutions on the situation in the former Yugoslavia, in particular resolutions 943 (1994), 970 (1995), 988 (1995) and 1003 (1995), the Council noted measures by the Federal Republic of Yugoslavia (Serbia and Montenegro) to continue the border closure with Bosnia and Herzegovina and therefore extended the partial suspension of sanctions against Serbia and Montenegro for an additional 180 days until 18 March 1996.It was noted that the border remained closed, except to humanitarian relief and the efforts of Serbia and Montenegro in this regard. There was greater co-operation between Serbia and Montenegro and the Mission of the International Conference on the Former Yugoslavia.

Acting under Chapter VII of the United Nations Charter, the international sanctions placed on Serbia and Montenegro were suspended until 18 March 1996. Restrictions and arrangements in resolutions 943 and 988 would continue to apply. The situation would remain constantly under review by the Security Council.

Vladimir the Great

Vladimir the Great (also (Saint) Vladimir of Kiev); Old East Slavic: Володимѣръ Свѧтославичь, Volodiměrъ Svętoslavičь, Old Norse Valdamarr gamli; c. 958 – 15 July 1015, Berestove) was a prince of Novgorod, grand Prince of Kiev, and ruler of Kievan Rus' from 980 to 1015.Vladimir's father was prince Sviatoslav of the Rurik dynasty. After the death of his father in 972, Vladimir, who was then prince of Novgorod, was forced to flee to Scandinavia in 976 after his brother Yaropolk had murdered his other brother Oleg and conquered Rus'. In Sweden, with the help from his relative Ladejarl Håkon Sigurdsson, ruler of Norway, he assembled a Varangian army and reconquered Novgorod from Yaropolk. By 980, Vladimir had consolidated the Kievan realm from modern-day Belarus, Russia and Ukraine to the Baltic Sea and had solidified the frontiers against incursions of Bulgarian, Baltic tribes and Eastern nomads. Originally a follower of Slavic paganism, Vladimir converted to Christianity in 988 and Christianized the Kievan Rus'.
