Iranian Peoples
The Iranian peoples or Iranic peoples are a diverse grouping of Indo-European peoples who are identified by their usage of the Iranian languages and other cultural similarities. The Proto-Iranians are believed to have emerged as a separate branch of the Indo-Iranians in Central Asia around the mid-2nd millennium BC. At their peak of expansion in the mid-1st millennium BC, the territory of the Iranian peoples stretched across the entire Eurasian Steppe, from the Great Hungarian Plain in the west to the Ordos Plateau in the east and the Iranian Plateau in the south.: "From the first millennium b.c., we have abundant historical, archaeological and linguistic sources for the location of the territory inhabited by the Iranian peoples. In this period the territory of the northern Iranians, they being equestrian nomads, extended over the whole zone of the steppes and the wooded steppes and even the semi-deserts from the Great Hungarian Plain to the Ordos in northern China." Th ...

Rasulid Dynasty
The Rasulids ( ar, بنو رسول, Banū Rasūl) were a Sunni Muslim dynasty who ruled Yemen from 1229 to 1454. History Origin of the Rasulids The Rasulids took their name from al-Amin's nickname "Rasul". The Zaidi Shi'i Imams of Yemen were the arch rivals of the Sunni Rasulids, and Zaidi sources emphasized the dynasty's Ghuzz origin to ensure the Qahtani majority of Yemen treats them more harshly as rootless outsiders. The term ''Ghuzz'' in Arabic sources is associated with the Oghuz Turks. The Ghuzz term appeared regularly in Zaidi literature and was for pre- Ottoman era of Oghuz Turkic mamluks & Turkic state ( Seljuk) who were actively expanding in Oman to the east of Yemen, later writers used this Arabic term which describes the Oghuz Turks, in the Zaidi sources, as their reference of the Turkic origin of the Rasulids. Some historians and genealogists that served the Rasulid dynasty claimed an Arab origin for the family and pressed a Ghassanid origin for the family, a b ...

Islamic Astrology
Some medieval Muslims took a keen interest in the study of astrology, despite the Islamic prohibitions (The Quran, points to the primary purpose of astrology as a means of providing physical guidance/navigation for an adherent, essentially considering its use in the capacity of horoscopes as forbidden.)partly because they considered the celestial bodies to be essential, partly because the dwellers of desert-regions often travelled at night, and relied upon knowledge of the constellations for guidance in their journeys.Wasim Aktar, ''Contributions of Ancient Arabian and Egyptian Scientists on Astronomy''Public Science & Reference, retrieved 19 August 2011. After the advent of Islam, the Muslims needed to determine the time of the prayers, the direction of the Kaaba, and the correct orientation of the mosque, all of which helped give a religious impetus to the study of astronomy and contributed towards the belief that the heavenly bodies were influential upon terrestrial affairs as we ...

Aden
Aden ( ar, عدن ' Yemeni: ) is a city, and since 2015, the temporary capital of Yemen, near the eastern approach to the Red Sea (the Gulf of Aden), some east of the strait Bab-el-Mandeb. Its population is approximately 800,000 people. Aden's natural harbour lies in the crater of a dormant volcano, which now forms a peninsula joined to the mainland by a low isthmus. This harbour, Front Bay, was first used by the ancient Kingdom of Awsan between the 7th to 5th centuries BC. The modern harbour is on the other side of the peninsula. Aden gets its name from the Gulf of Aden. Aden consists of a number of distinct sub-centres: Crater, the original port city; Ma'alla, the modern port; Tawahi, known as "Steamer Point" in the colonial period; and the resorts of Gold Mohur. Khormaksar, on the isthmus that connects Aden proper with the mainland, includes the city's diplomatic missions, the main offices of Aden University, and Aden International Airport (the former British Roy ...

13th-century Iranian Astronomers
The 13th century was the century which lasted from January 1, 1201 ( MCCI) through December 31, 1300 ( MCCC) in accordance with the Julian calendar. The Mongol Empire was founded by Genghis Khan, which stretched from Eastern Asia to Eastern Europe. The conquests of Hulagu Khan and other Mongol invasions changed the course of the Muslim world, most notably the Siege of Baghdad (1258), the destruction of the House of Wisdom and the weakening of the Mamluks and Rums which, according to historians, caused the decline of the Islamic Golden Age. Other Muslim powers such as the Mali Empire and Delhi Sultanate conquered large parts of West Africa and the Indian subcontinent, while Buddhism witnessed a decline through the conquest led by Bakhtiyar Khilji. The Southern Song dynasty would begin the century as a prosperous kingdom but would eventually be invaded and annexed into the Yuan dynasty of the Mongols. The Kamakura Shogunate of Japan would be invaded by the Mongols. Goryeo resisted ...

Scientists Who Worked On Qibla Determination
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by  2, although by other definitions 1 is the second natural number, following  0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ...

Year Of Birth Unknown
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the mean ...
