A wormhole (Einstein-Rosen bridge) is a hypothetical structure connecting disparate points in spacetime, and is based on a special solution of the Einstein field equations.A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, different points in time, or both). Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. Many scientists postulate that wormholes are merely projections of a...

Naram-Sin, also transcribed Narām-Sîn or Naram-Suen (Akkadian: 𒀭𒈾𒊏𒄠𒀭𒂗𒍪: DNa-ra-am DSîn, meaning "Beloved of the Moon God Sîn", the "𒀭" being a silent honorific for "Divine"), was a ruler of the Akkadian Empire, who reigned c. 2254–2218 BC (middle chronology), and was the third successor and grandson of King Sargon of Akkad. Under Naram-Sin the empire reached its maximum strength. He was the first Mesopotamian king known to have claimed divinity for himself, taking the title "God of Akkad", and the first to claim the title "King of the Four Quarters, King of the Universe". As part of that he became city god of Akkade in the same way Enlil was city god of Nippur. Biography Naram-Sin was born as a son of Manishtushu. He was thus a nephew of King Rimush and grandson of Sargon and Tashlultum. Naram-Sin's aunt was the High Priestess En-hedu-ana. To be fully correct, rather than Naram-Sin or Naram-Suen "in Old Akkadian, the name in question should rather be reconstructed as Naram-Suyin (more precisely, /narām-tsuyin/...

A pulsar (from pulsating radio source) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing toward Earth (similar to the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission. Neutron stars are very dense and have short, regular rotational periods. This produces a very precise interval between pulses that ranges from milliseconds to seconds for an individual pulsar. Pulsars are one of the candidates for the source of ultra-high-energy cosmic rays. (See also centrifugal mechanism of acceleration.) The periods of pulsars make them very useful tools for astronomers. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12 in 1992. In 1983, certain types of pulsars were detected that, at that time, exceeded the accuracy of atomic clocks in keeping time. ...

Melbourne ( (listen) MEL-bərn; Boonwurrung/Woiwurrung: Narrm or Naarm) is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in both Australia and Oceania. Its name generally refers to a 9,993 km2 (3,858 sq mi) metropolitan area known as Greater Melbourne, comprising an urban agglomeration of 31 local municipalities, although the name is also used specifically for the local municipality of City of Melbourne based around its central business area. The metropolis occupies much of the northern and eastern coastlines of Port Phillip Bay and spreads into the Mornington Peninsula, part of West Gippsland, as well as the hinterlands towards the Yarra Valley, the Dandenong and Macedon Ranges. It has a population over 5 million (19% of the population of Australia, as per 2021 census), mostly residing to the east side of the city centre, and its inhabitants are commonly referred to as "Melburnians".The area of Melbourne has been home to Aboriginal...

Myristica is a genus of trees in the family Myristicaceae. There are over 150 species, distributed in Asia and the western Pacific.The type species of the genus, and the most economically important member, is Myristica fragrans (the nutmeg tree), from which mace is also derived. Etymology The name Myristica is from the Greek adjective myristikos, meaning ‘fragrant, for anointing’, referring to its early use. The adjective is from the noun myron (‘perfume, ointment, anointing oil’). Description All or nearly all species are dioecious. Knuth (1904) however cites a report of trees being male in their sex expression when young and female later. Perianth of one whorl of three largely united segments. Stamens two to thirty, partly or wholly united. The ovary is superior, consisting of a single uniovulate carpel. Species in this genus use secondary pollen...

Google Assistant is a virtual assistant software application developed by Google that is primarily available on mobile and home automation devices. Based on artificial intelligence, Google Assistant can engage in two-way conversations, unlike the company's previous virtual assistant, Google Now. Google Assistant debuted in May 2016 as part of Google's messaging app Allo, and its voice-activated speaker Google Home. After a period of exclusivity on the Pixel and Pixel XL smartphones, it was deployed on other Android devices starting in February 2017, including third-party smartphones and Android Wear (now Wear OS), and was released as a standalone app on the iOS operating system in May 2017. Alongside the announcement of a software development kit in April 2017, Assistant has been further extended to support a large variety of devices, including cars and third-party smart home appliances. The functionality of the Assistant can also be enhanced by third-party developers. Users primarily interact with the Google Assistant through natural voice, though keyboard input is also supported. Assistant is able to answer questions, schedule...

The E-class trams are three-section, four-bogie articulated trams that were first introduced to the Melbourne tram network in 2013, built at the Dandenong works of Bombardier Transportation (later Alstom) with the propulsion systems and bogies coming from Bombardier/Alstom factories in Germany. The E-class is part of the Tram Procurement Program, a Public Transport Victoria project aimed at increasing capacity and reliability of the tram network through the introduction of new trams, creation of new depot space, and upgrades to existing infrastructure. In September 2010, 50 were ordered with an option to purchase a further 100. In May 2015, a further 20 were ordered, followed by additional orders for 10 in May 2017, September 2018 and May 2019, taking the total to 100. The first tram was delivered in June 2013 and, after testing, entered service on route 96 on 4 November 2013. History E1-class In July 2009, the Victorian Government called for expressions of interest for the construction of 50 new trams. The expression of interest stipulated that the...

Writing is a neuropsychological activity involving cognitive and physical processes and the use of writing systems to structure and translate human thoughts into persistent representations of human language. A system of writing relies on many of the same semantic structures as the language it represents, such as lexicon and syntax, with the added dependency of a system of symbols representing that language's phonology and morphology. Nevertheless, written language may take on characteristics distinctive from any available in spoken language.The outcome of this activity, also called "writing," and sometimes a "text," is a series of physically inscribed, mechanically transferred, or digitally represented linguistic symbols. The interpreter or activator of a text is called a "reader".Writing systems do not themselves constitute languages (with the debatable exception of computer languages); they are a means of rendering language into a form that can be reconstructed by other humans separated by time and/or space. While not all languages use a writing system, those that do can complement and extend capacities of spoken language by...
