Mediterranean Climate
A Mediterranean climate /ˌmɛdɪtəˈreɪniən/ or dry summer climate is characterized by dry summers and mild, wet winters. The climate receives its name from the Mediterranean Basin, where this climate type is most common. Mediterranean climate zones are typically located along the western sides of continents, between roughly 30 and 45 degrees north and south of the equator. The main cause of Mediterranean, or dry summer climate, is the subtropical ridge which extends northwards during the summer and migrates south during the winter due to increasing north-south temperature differences. The resulting vegetation of Mediterranean climates are the garrigue or maquis in the Mediterranean Basin, the chaparral in California, the fynbos in South Africa, the mallee in Australia, and the matorral in Chile. Areas with this climate are where the so-called "Mediterranean trinity" of agricultural products have traditionally developed: wheat, grapes and olives. Most historic cities of the Mediterranean basin lie within Mediterranean climatic zones, including Algiers, Athens, Barcelona, Beirut, İzmir, Jerusalem, Marseille, Naples, Rome, Tunis, Valencia, and Valletta. Major cities with Mediterranean climates outside of the Mediterranean basin include Adelaide, Cape Town, Casablanca, Dushanbe, Lisbon, Los Angeles , Perth, Porto, Sacramento, San Diego, San Francisco , San Jose, CA, Santiago, Tashkent and Victoria.

Wenedyk
Wenedyk is a naturalistic constructed language, created by the Dutch translator Jan van Steenbergen (who also co-created the international auxiliary language Interslavic). It is used in the fictional Republic of the Two Crowns (based on the Republic of Two Nations), in the alternate timeline of Ill Bethisad. Officially, Wenedyk is a descendant of Vulgar Latin with a strong Slavic admixture, based on the premise that the Roman Empire incorporated the ancestors of the Poles in their territory. Less officially, it tries to show what Polish would have looked like if it had been a Romance instead of a Slavic language. On the Internet, it is well-recognized as an example of the altlang genre, much like Brithenig and Breathanach. The idea for the language was inspired by such languages as Brithenig and Breathanach, languages that bear a similar relationship to the Celtic languages as Wenedyk does to Polish. The language itself is based entirely on (Vulgar) Latin and Polish: all phonological, morphological, and syntactic changes that made Polish develop from Common Slavic are applied to Vulgar Latin. As a result, vocabulary and morphology are predominantly Romance in nature, whereas phonology, orthography and syntax are essentially the same as in Polish. Wenedyk uses the modern standard Polish orthography, including (for instance) ⟨w⟩ for /v/ and ⟨ł⟩ for /w/. Wenedyk plays a role in the alternate history of Ill Bethisad, where it is one of the official languages of the Republic of the Two Crowns. In 2005 Wenedyk underwent a major revision due to a better understanding of Latin and Slavic sound and grammar changes. In the process, the author was assisted by the Polish linguist Grzegorz Jagodziński. The dictionary on the WWW page linked below contains over 4000 entries. The language has acquired some media attention in Poland, including a few online news articles and an article in the monthly Wiedza i Życie ("Knowledge and Life").

Cosmology
Cosmology (from grc κόσμος (kósmos) 'world', and -λογία (-logía) 'study of') is a branch of physics and metaphysics dealing with the nature of the universe. The term cosmology was first used in English in 1656 in Thomas Blount's Glossographia, and in 1731 taken up in Latin by German philosopher Christian Wolff, in Cosmologia Generalis. Religious or mythological cosmology is a body of beliefs based on mythological, religious, and esoteric literature and traditions of creation myths and eschatology. In the science of astronomy it is concerned with the study of the chronology of the universe. Physical cosmology is the study of the observable universe's origin, its large-scale structures and dynamics, and the ultimate fate of the universe, including the laws of science that govern these areas. It is investigated by scientists, such as astronomers and physicists, as well as philosophers, such as metaphysicians, philosophers of physics, and philosophers of space and time. Because of this shared scope with philosophy, theories in physical cosmology may include both scientific and non-scientific propositions, and may depend upon assumptions that cannot be tested. Physical cosmology is a sub-branch of astronomy that is concerned with the Universe as a whole. Modern physical cosmology is dominated by the Big Bang theory, which attempts to bring together observational astronomy and particle physics; more specifically, a standard parameterization of the Big Bang with dark matter and dark energy, known as the Lambda-CDM model. Theoretical astrophysicist David N. Spergel has described cosmology as a "historical science" because "when we look out in space, we look back in time" due to the finite nature of the speed of light.

Udvada Atash Behram
The Udvada Atash Behram, also known as the Iran Shah, "King of Iran", is a sacred fire housed in a temple in Udvada, Gujarat on the west coast of India. It is the first of the eight fire temples (holy place of worship) of the Zoroastrian religion in the country. The Atash Bahram, meaning "Victorious Fire", is the oldest fire temples in India, dated to the eight century, and represents the historical cultural and religious links with Iran. The current temple housing the sacred fire was built in 1742 by Motlibai Wadia from Bombay. The temple structure, built spaciously, is well decorated and contains the Dasturji Koyaji Mirza hall and a museum. The main hall of the temple is accessed through a two-stage staircase. The temple attracts Zoroastrian pilgrims from all parts of India, Pakistan and from around the world.

Differentiable Vector-Valued Functions from Euclidean Space
In the mathematical discipline of functional analysis, a differentiable vector-valued function from Euclidean space is a differentiable function valued in a topological vector space (TVS) whose domains is a subset of some finite-dimensional Euclidean space. It is possible to generalize the notion of derivative to functions whose domain and codomain are subsets of arbitrary topological vector spaces (TVSs) in multiple ways. But when the domain of a TVS-valued function is a subset of a finite-dimensional Euclidean space then many of these notions become logically equivalent resulting in a much more limited number of generalizations of the derivative and additionally, differentiability is also more well-behaved compared to the general case. This article presents the theory of [math]\displaystyle{ k }[/math]-times continuously differentiable functions on an open subset [math]\displaystyle{ \Omega }[/math] of Euclidean space [math]\displaystyle{ \R^n }[/math] ([math]\displaystyle{ 1 \leq n \lt \infty }[/math]), which is an important special case of differentiation between arbitrary TVSs. This importance stems partially from the fact that every finite-dimensional vector subspace of a Hausdorff topological vector space is TVS isomorphic to Euclidean space [math]\displaystyle{ \R^n }[/math] so that, for example, this special case can be applied to any function whose domain is an arbitrary Hausdorff TVS by restricting it to finite-dimensional vector subspaces. All vector spaces will be assumed to be over the field [math]\displaystyle{ \mathbb{F}, }[/math] where [math]\displaystyle{ \mathbb{F} }[/math] is either the real numbers [math]\displaystyle{ \R }[/math] or the complex numbers [math]\displaystyle{ \Complex. }[/math]

Curtilage
In law, the curtilage of a house or dwelling is the land immediately surrounding it, including any closely associated buildings and structures, but excluding any associated "open fields beyond", and also excluding any closely associated buildings, structures, or divisions that contain the separate intimate activities of their own respective occupants with those occupying residents being persons other than those residents of the house or dwelling of which the building is associated. It delineates the boundary within which a home owner can have a reasonable expectation of privacy and where "intimate home activities" take place. It is an important legal concept in certain jurisdictions for the understanding of search and seizure, conveyancing of real property, burglary, trespass, and land use planning. In urban properties, the location of the curtilage may be evident from the position of fences, wall and similar; within larger properties it may be a matter of some legal debate as to where the private area ends and the "open fields" start.

Interval Scheduling
Interval scheduling is a class of problems in computer science, particularly in the area of algorithm design. The problems consider a set of tasks. Each task is represented by an interval describing the time in which it needs to be executed. For instance, task A might run from 2:00 to 5:00, task B might run from 4:00 to 10:00 and task C might run from 9:00 to 11:00. A subset of intervals is compatible if no two intervals overlap. For example, the subset {A,C} is compatible, as is the subset {B}; but neither {A,B} nor {B,C} are compatible subsets, because the corresponding intervals within each subset overlap. The interval scheduling maximization problem (ISMP) is to find a largest compatible set - a set of non-overlapping intervals of maximum size. The goal here is to execute as many tasks as possible. In an upgraded version of the problem, the intervals are partitioned into groups. A subset of intervals is compatible if no two intervals overlap, and moreover, no two intervals belong to the same group (i.e. the subset contains at most a single representative interval of each group). The group interval scheduling decision problem (GISDP) is to decide whether there exists a compatible set in which all groups are represented. The goal here is to execute a single representative task from each group. GISDPk is a restricted version of GISDP in which the number of intervals in each group is at most k. The group interval scheduling maximization problem (GISMP) is to find a largest compatible set - a set of non-overlapping representatives of maximum size. The goal here is to execute a representative task from as many groups as possible. GISMPk is a restricted version of GISMP in which the number of intervals in each group is at most k. This problem is often called JISPk, where J stands for Job. GISMP is the most general problem; the other two problems can be seen as special cases of it:

Chronology of Jesus
A chronology of Jesus aims to establish a timeline for the events of the life of Jesus. Scholars have correlated Jewish and Greco-Roman documents and astronomical calendars with the New Testament accounts to estimate dates for the major events in Jesus's life. Two main approaches have been used to estimate the year of the birth of Jesus: one based on the accounts in the Gospels of his birth with reference to King Herod's reign, and the other by subtracting his stated age of "about 30 years" when he began preaching. Most scholars, on this basis, assume a date of birth between 6 and 4 BC. Three details have been used to estimate the year when Jesus began preaching: a mention of his age of "about 30 years" during "the fifteenth year" of the reign of Tiberius Caesar, another relating to the date of the building of the Temple in Jerusalem, and yet another concerning the death of John the Baptist. Hence, scholars estimate that Jesus began preaching and gathering followers around AD 28–29. According to the three synoptic gospels Jesus continued preaching for at least one year, and according to John the Evangelist for three years. Five methods have been used to estimate the date of the crucifixion of Jesus. One uses non-Christian sources such as Josephus and Tacitus. Another works backwards from the historically well-established trial of the Apostle Paul by the Roman proconsul Gallio in Corinth in AD 51/52 to estimate the date of Paul's conversion. Both methods result in AD 36 as an upper bound to the crucifixion. Thus, scholars generally agree that Jesus was crucified between AD 30 and AD 36. Isaac Newton's astronomical method calculates those ancient Passovers (always defined by a full moon) which are preceded by a Friday, as specified by all four Gospels; this leaves two potential crucifixion dates, 7 April AD 30 and 3 April AD 33. In the lunar eclipse method, the Apostle Peter's statement that the moon turned to blood at the crucifixion (Acts of the Apostles 2:14-21) is taken to refer to the lunar eclipse of 3 April AD 33; although astronomers are discussing whether the eclipse was visible as far west as Jerusalem. Recent astronomical research uses the contrast between the synoptic date of Jesus' last Passover on the one hand with John's date of the subsequent "Jewish Passover" on the other hand, to propose Jesus' Last Supper to have been on Wednesday, 1 April AD 33 and the crucifixion on Friday 3 April AD 33.
