Ariel School
On September 16, 1994, there was a UFO sighting outside Ruwa, Zimbabwe. 62 pupils at the Ariel School aged between six and twelve claimed that they saw one or more silver craft descend from the sky and land on a field near their school. One or more creatures dressed all in black then approached the children and telepathically communicated to them a message with an environmental theme. The Fortean writer Jerome Clark has called the incident the “most remarkable close encounter of the third kind of the 1990s”. Skeptics have described the incident as one of mass hysteria. Not all the children at the school that day claimed that they saw something. Several of those that did maintain that their account of the incident is true. Background Ruwa is a small agricultural centre located 22 km south-east of the capital Harare. At the time of the incident, it was not a town but only a local place-name, "little more than a crossroads in an agricultural region". Ariel School was an ex ...

Unidentified Flying Object
An unidentified flying object (UFO), more recently renamed by US officials as a UAP (unidentified aerial phenomenon), is any perceived aerial phenomenon that cannot be immediately identified or explained. On investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained. Scientists and skeptic organizations such as the Committee for Skeptical Inquiry have provided prosaic explanations for a large number of claimed UFOs being caused by natural phenomena, human technology, delusions, or hoaxes. Small but vocal groups of ufologists favour unconventional, pseudoscientific hypotheses, often claiming that UFOs are evidence of extraterrestrial intelligence. Beliefs surrounding UFOs have inspired parts of new religions. While unusual sightings have been reported in the sky throughout history, UFOs became culturally prominent after World War II, escalating during the Space Age. The 20th century saw studies and investigat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recess (break)
Recess is a general term for a period in which a group of people are temporarily dismissed from their duties. In education, recess is the American and Australian term (known as ''break'' or ''playtime'' in the UK), where students have a mid morning snack and play before having lunch after a few more lessons. Typically ten to thirty minutes, in elementary school where students are allowed to leave the school's interior to enter its adjacent outside park where they play on equipment such as slides and swings, play basketball, tetherball, study, make up any missing assignments or talk. Many middle and high schools also offer a recess to provide students with a sufficient opportunity to consume quick snacks, communicate with their peers, visit the restroom, study, and various other activities. Importance of play in child development During recess, children play, and learning through play has been long known as a vital aspect of childhood development. Some of the earliest ...

Scientific Skepticism
Scientific skepticism or rational skepticism (also spelled scepticism), sometimes referred to as skeptical inquiry, is a position in which one questions the veracity of claims lacking empirical evidence. In practice, the term most commonly references the examination of claims and theories that appear to be beyond mainstream science, rather than the routine discussions and challenges among scientists. Scientific skepticism differs from philosophical skepticism, which questions humans' ability to claim any knowledge about the nature of the world and how they perceive it, and the similar but distinct methodological skepticism, which is a systematic process of being skeptical about (or doubting) the truth of one's beliefs. in The skeptical movement ( British spelling: sceptical movement) is a contemporary social movement based on the idea of scientific skepticism. The movement has the goal of investigating claims made on fringe topics and determining whether they are supported ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ufology
Ufology ( ) is the investigation of unidentified flying objects (UFOs) by people who believe that they may be of extraordinary origins (most frequently of extraterrestrial alien visitors). While there are instances of government, private, and fringe science investigations of UFOs, ufology is generally regarded by skeptics and science educators as a canonical example of pseudoscience. Etymology Ufology is a neologism derived from ''UFO'' (a term apparently coined by Edward J. Ruppelt), and is derived from appending the acronym UFO with the suffix '' -logy'' (from the Ancient Greek ''λογία'' (''logiā'')). Early uses of ufology include an article in ''Fantastic Universe'' (1957) and a 1958 presentation for the UFO "research organization" The Planetary Center. Historical background The roots of ufology include the "mystery airships" of the late 1890s, the "foo fighters" reported by Allied airmen during World War II, the "ghost fliers" of Europe and North America during t ...

Tikoloshe
In Zulu mythology, Tikoloshe, Tikolosh, Tokoloshe, Tokolotshe, Thokolosi or Hili is a dwarf-like water sprite. It is a mischievous and evil spirit that can become invisible by drinking water or swallowing a stone. Tokoloshes are called upon by malevolent people to cause trouble for others. At its least harmful, a tokoloshe can be used to scare children, but its power extends to causing illness or even the death of the victim. The creature might be banished by a pastor (especially with an apostolic calling), who has the power to expel it from the area. It is also considered a part of superstition and is often used in a satirical manner as a reference to overcome. Mythology The advent of the phantom Tokoloshe came about through Bantu folklore to explain why people inexplicably died while sleeping in their rondavels at night. Traditionally, these people slept on the floor on grass mats encircling a wood fire that kept them warm during sub-freezing cold winter nights on the hi ...

Extraterrestrial Life
Extraterrestrial life, colloquially referred to as alien life, is life that may occur outside Earth and which did not originate on Earth. No extraterrestrial life has yet been conclusively detected, although efforts are underway. Such life might range from simple forms like prokaryotes to intelligent beings, possibly bringing forth civilizations that might be far more advanced than humankind. The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life is known as astrobiology. Speculation about the possibility of inhabited "worlds" outside the planet Earth dates back to antiquity. Multiple early Christian writers discussed the idea of a "plurality of worlds" as proposed by earlier thinkers such as Democritus; Augustine references Epicurus's idea of innumerable worlds "throughout the boundless immensity of space" (originally expressed in his Letter to Herodotus) in ''The City of God''. In his first century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airplane
An airplane or aeroplane (informally plane) is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, Propeller (aircraft), propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, air transportation, transportation of goods and people, military aviation, military, and Experimental aircraft, research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometersMeasured in RTKs—an RTK is one tonne of revenue freight carried one kilometer. of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be unmanned aerial vehicle, remotely or computer-controlled such as drones.

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioac ...

The Harvard Crimson
''The Harvard Crimson'' is the student newspaper of Harvard University and was founded in 1873. Run entirely by Harvard College undergraduates, it served for many years as the only daily newspaper in Cambridge, Massachusetts. Beginning in the fall of 2022, the paper transitioned to a weekly publishing model. About ''The Crimson'' Any student who volunteers and completes a series of requirements known as the "comp" is elected an editor of the newspaper. Thus, all staff members of ''The Crimson''—including writers, business staff, photographers, and graphic designers—are technically "editors". (If an editor makes news, he or she is referred to in the paper's news article as a "''Crimson'' editor", which, though important for transparency, also leads to characterizations such as "former President John F. Kennedy '40, who was also a ''Crimson'' editor, ended the Cuban Missile Crisis.") Editorial and financial decisions rest in a board of executives, collectively called a "gua ...
