Te Lapa
''Te lapa'' is a Polynesian term for an unexplained and scientifically unproven light phenomenon underneath, or on the surface of, the ocean. ''Te lapa'' has been loosely translated as "flashing light", "underwater lightning", "the flashing", or "something that flashes". It was used by historic and modern Polynesians as a navigation aid to find islands in the Pacific Ocean. In some instances, it has been theorized to be bioluminescence or electromagnetic in nature. Other hypotheses include the interference patterns of intersecting waves creating a raised curve acting as a lens, but would not explain the source of light. David Lewis speculated that ''te lapa'' may originate from luminescence of organisms, or related to deep swell, ground swell, or backwash waves from reefs or islands. History ''Te lapa'' was brought to the attention of academia by David Lewis with the publication of his book ''We, the Navigators'' in 1972. The book dispelled the former academic belief that Po ...

Polynesians
Polynesians form an ethnolinguistic group of closely related people who are native to Polynesia (islands in the Polynesian Triangle), an expansive region of Oceania in the Pacific Ocean. They trace their early prehistoric origins to Island Southeast Asia and form part of the larger Austronesian ethnolinguistic group with an Urheimat in Taiwan. They speak the Polynesian languages, a branch of the Oceanic subfamily of the Austronesian language family. there were an estimated 2 million ethnic Polynesians (full and part) worldwide, the vast majority of whom either inhabit independent Polynesian nation-states (Samoa, Niue, Cook Islands, Tonga, and Tuvalu) or form minorities in countries such as Australia, Chile (Easter Island), New Zealand, France (French Polynesia and Wallis and Futuna), and the United States (Hawaii and American Samoa), in addition to the British Overseas Territory of the Pitcairn Islands. New Zealand had the highest population of Polynesians, estimated at 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academia
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary education, secondary or tertiary education, tertiary higher education, higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and Skills, skill, north of Ancient Athens, Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the Gymnasium (ancient Greece), gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive Grove (nature), grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 3 ...

Comet
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several mill ...

Satellite
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 Transponder (satellite communications), transponders. Many satellites use a Satellite bus, standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming Satellite constellation, 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 Broadcast relay station, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteor
A meteoroid () is a small rocky or metallic body in outer space. Meteoroids are defined as objects significantly smaller than asteroids, ranging in size from grains to objects up to a meter wide. Objects smaller than this are classified as micrometeoroids or space dust. Most are fragments from comets or asteroids, whereas others are collision impact debris ejected from bodies such as the Moon or Mars. When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of , aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star". Meteors typically become visible when they are about 100 km above sea level. A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. A meteorite is the remains of a meteoroid th ...

Tektite
Tektites (from grc, τηκτός , meaning 'molten') are gravel-sized bodies composed of black, green, brown or grey natural glass formed from terrestrial debris ejected during meteorite impacts. The term was coined by Austrian geologist Franz Eduard Suess (1867–1941), son of Eduard Suess. They generally range in size from millimetres to centimetres.

Ball Lightning
Ball lightning is a rare and unexplained phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter. Though usually associated with thunderstorms, the observed phenomenon is reported to last considerably longer than the split-second flash of a lightning bolt, and is a phenomenon distinct from St. Elmo's fire. Some 19th-century reports describe balls that eventually explode and leave behind an odor of sulfur. Descriptions of ball lightning appear in a variety of accounts over the centuries and have received attention from scientists. An optical spectrum of what appears to have been a ball lightning event was published in January 2014 and included a video at high frame rate. Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but how these relate to the supposed phenomenon remains unclear. Scientists have proposed a number of hypotheses to explain reports of ball lightning over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tikopia
Tikopia is a high island in the southwestern Pacific Ocean. It forms a part of the Melanesian nation state of Solomon Islands but is culturally Polynesian. The first Europeans arrived on 22 April 1606 as part of the Spanish expedition of Pedro Fernandes de Queirós. Location and geography Covering an area of , the island is the remnant of an extinct volcano. Its highest point, Mt. Reani, reaches an elevation of above sea level. Lake Te Roto covers an old volcanic crater which is deep. Tikopia's location is relatively remote. It is sometimes grouped with the Santa Cruz Islands. Administratively, Tikopia belongs to Temotu Province as the southernmost of the Solomon Islands. Some discussions of Tikopian society include its nearest neighbour, the even tinier island of Anuta. History as a Polynesian outlier While it is located in Melanesia, the people of Tikopia are culturally Polynesian. Their language, Tikopian, is a member of the Samoic branch of the Polynesian languages. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonga
Tonga (, ; ), officially the Kingdom of Tonga ( to, Puleʻanga Fakatuʻi ʻo Tonga), is a Polynesian country and archipelago. The country has 171 islands – of which 45 are inhabited. Its total surface area is about , scattered over in the southern Pacific Ocean. As of 2021, according to Johnson's Tribune, Tonga has a population of 104,494, 70% of whom reside on the main island, Tongatapu. The country stretches approximately north-south. It is surrounded by Fiji and Wallis and Futuna (France) to the northwest; Samoa to the northeast; New Caledonia (France) and Vanuatu to the west; Niue (the nearest foreign territory) to the east; and Kermadec (New Zealand) to the southwest. Tonga is about from New Zealand's North Island. First inhabited roughly 2,500 years ago by the Lapita civilization, Tonga's Polynesian settlers gradually evolved a distinct and strong ethnic identity, language, and culture as the Tongan people. They were quick to establish a powerful footing acr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikunau
Nikunau is a low coral atoll in the Gilbert Islands that forms a council district of the Republic of Kiribati. It consists of two parts, with the larger in the northwest, joined by an isthmus about wide. There are several landlocked hypersaline lagoons within the island, covering about . The island is surrounded by a narrow fringing reef. Its vegetation is moderately dense and consists largely of coconut palms and pandanus. The island's population includes 1,789 Kain Nikunau I-Kiribati people (at the most recent census). Typically, there are also a few other I-Kiribati, working for the Republic Government or the Nikunau Island Council. From time to time the United States Peace Corps and other I-Matang volunteers have been stationed there. Other residents over the years have included castaways and beachcombers in the days of whaling and itinerant trading, Protestant Samoan pastors, traders and agents running the island's trade stores and cooperatives (e.g. Andrew Turner, Tom Day, ...
