Arthur C
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ...

Ravana
Ravana (; , , ) is a rakshasa king of the island of Lanka, and the chief antagonist of the Hindu epic ''Ramayana'' and its adaptations. In the ''Ramayana'', Ravana is described to be the eldest son of sage Vishrava and rakshasi Kaikesi. He abducted Prince Rama's wife Sita and took her to his kingdom of Lanka, where he held her in the Ashoka Vatika. Later, Rama, with the support of vanara King Sugriva and his army of vanaras, launched an invasion against Ravana in Lanka. Ravana was subsequently slain and Rama rescued his beloved wife Sita. Ravana is widely portrayed to be an evil character, though he also has many qualities that make him a learned scholar. He was well-versed in the six shastras and the four Vedas. Ravana is also considered to be the most revered devotee of Shiva. Images of Ravana are seen associated with Shiva at some temples. He also appears in the Buddhist Mahayana text ''Laṅkāvatāra Sūtra'', in Buddhist Ramayanas and Jatakas, as well as in Jain Ra ...

Satellites Deployed From The International Space Station
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

Spacecraft Which Reentered In 2021
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit ( space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sinhala Language
Sinhala ( ; , ''siṁhala'', ), sometimes called Sinhalese (), is an Indo-Aryan languages, Indo-Aryan language primarily spoken by the Sinhalese people of Sri Lanka, who make up the largest ethnic group on the island, numbering about 16 million. Sinhala is also spoken as the first language by other ethnic groups in Sri Lanka, totalling about 2 million people as of 2001. It is written using the Sinhala script, which is a Brahmic scripts, Brahmic script closely related to the Grantha script of South India. Sinhala is one of the official and national languages of Sri Lanka. Along with Pali, it played a major role in the development of Theravada, Theravada Buddhist literature. The early form of the Sinhala language, is attested as early as the 3rd century BCE. The language of these inscriptions with long vowels and aspirated consonants is a Prakrit similar to Magadhi, a regional associate of the Middle Indian Prakrits that has been used during the time of the Buddha.

Dhadu Monara
According to folk tales, Dhadu Monara ("Wooden Peacock") was the legendary pre-historic aircraft used by King Ravana of Sri Lanka, to travel among countries under his command. But no archaeological evidence has been found anywhere in Sri Lanka to prove the existence of such an aircraft. The Department of Archaeology of Sri Lanka has rejected this story as a mere fiction since there is no archaeological evidence or credible historical records to prove its existence. According to the Sinhalese legend the Lakegala Rock is thought to mark the location of the Lankapura Kingdom and King Ravana’s capital. It is also said that Ravana met Princess Sita, the queen of Rama, beside this rock. Most Meemure villagers believe that Lakegala is the place where King Ravana flew his aeroplane ''Dhadu Monara'', which he used to capture Sita from India India, officially the Republic of India (Hindi: ), is a country in South Asia.
