Causality is an influence by which one event, process, state, or object (acause) contributes to the production of another event, process, state, or object (an effect) where the cause is partly responsible for the effect, and the effect is partly dependent on the cause. In general, a process has many causes, which are also said to be causal factors for it, and all lie in its past. An effect can in turn be a cause of, or causal factor for, many other effects, which all lie in its future. Some writers have held that causality is metaphysically prior to notions of time and space.
The phrase "correlation does not imply causation" refers to the inability to legitimately deduce a cause-and-effect relationship between two events or variables solely on the basis of an observed association or correlation between them. The idea that "correlation implies causation" is an example of a questionable-cause logical fallacy, in which two events occurring together are taken to have established a cause-and-effect relationship. This fallacy is also known by the Latin phrase cum hoc ergo propter hoc. This differs from the fallacy known as post hoc ergo propter hoc, in which an event following another is seen as a necessary consequence of the former event, and from conflation, the errant merging of two events, ideas, databases, etc., into one.
Supernatural refers to phenomena or entities that are beyond the laws of nature. The term is derived from Medieval Latin supernaturalis, from Latin super- + natura (nature). Although the corollary term "nature" has had multiple meanings since the ancient world, the term "supernatural" emerged in the Middle Ages and did not exist in the ancient world.
An economic bubble is a period when current asset prices greatly exceed their intrinsic valuation, being the valuation that the underlying long-term fundamentals justify. Bubbles can be caused by overly optimistic projections about the scale and sustainability of growth, and/or by the belief that intrinsic valuation is no longer relevant when making an investment. They have appeared in most asset classes, including equities, commodities, real estate, and even esoteric assets. Bubbles usually form as a result of either excess liquidity in markets, and/or changed investor psychology. Large multi-asset bubbles, are attributed to central banking liquidity.
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility. Examples include lethal effects to individuals, large radioactivity release to the environment, reactor core melt." The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011.
The term Inductive reasoning is used to refer to any method of reasoning in which broad generalizations or principles are derived from a body of observations. This article is concerned with the inductive reasoning other than deductive reasoning, where the conclusion of a deductive argument is certain given the premises are correct; in contrast, the truth of the conclusion of an inductive argument is at best probable, based upon the evidence given.
On the night of 24 August 2004, explosive devices were detonated on board two domestic passenger flights that had taken off from Domodedovo International Airport in Moscow, Russia, causing the destruction of both aircraft and the loss of all 90 people on board them.
A criticality accident is an accidental uncontrolled nuclear fission chain reaction. It is sometimes referred to as a critical excursion, critical power excursion, or divergent chain reaction. Any such event involves the unintended accumulation or arrangement of a critical mass of fissile material, for example enriched uranium or plutonium. Criticality accidents can release potentially fatal radiation doses if they occur in an unprotected environment.
A proximate cause is an event which is closest to, or immediately responsible for causing, some observed result. This exists in contrast to a higher-level ultimate cause which is usually thought of as the "real" reason something occurred.
The Curse of Tippecanoe is an urban legend about the deaths in office of presidents of the United States who were elected in years divisible by 20. According to the legend, Tenskwatawa, leader of Native American tribes defeated in 1811 at the Battle of Tippecanoe by a military expedition led by William Henry Harrison, had cursed the "Great White Fathers".
The Ufa train disaster was a railway accident that occurred on 4 June 1989, in Iglinsky District, Bashkir ASSR, Russian SFSR, Soviet Union, when an explosion killed 575 people and injured 800 more. It is the deadliest rail disaster during peacetime in Soviet/Russian history and the second-deadliest overall after the Vereshchyovka train disaster.
Nuclear safety is defined by the International Atomic Energy Agency (IAEA) as "The achievement of proper operating conditions, prevention of accidents or mitigation of accident consequences, resulting in protection of workers, the public and the environment from undue radiation hazards". The IAEA defines nuclear security as "The prevention and detection of and response to, theft, sabotage, unauthorized access, illegal transfer or other malicious acts involving nuclear materials, other radioactive substances or their associated facilities".
The Dyatlov Pass incident was an event in which nine Soviet hikers died in the northern Ural Mountains between February 1 and 2, 1959, under uncertain circumstances. The experienced trekking group from the Ural Polytechnical Institute, led by Igor Dyatlov, had established a camp on the eastern slopes of Kholat Syakhl in the Russian SFSR of the Soviet Union. Overnight, something caused them to cut their way out of their tent and flee the campsite while inadequately dressed for the heavy snowfall and sub-zero temperatures.
Accident analysis is a process carried out in order to determine the cause or causes of an accident so as to prevent further accidents of a similar kind. It is part of accident investigation or incident investigation. These analyses may be performed by a range of experts, including forensic scientists, forensic engineers or health and safety advisers. Accident investigators, particularly those in the aircraft industry, are colloquially known as "tin-kickers". Health and safety and patient safety professionals prefer using the term "incident" in place of the term "accident". Its retrospective nature means that accident analysis is primarily an exercise of directed explanation; conducted using the theories or methods the analyst has to hand, which directs the way in which the events, aspects, or features of accident phenomena are highlighted and explained. These analyses are also invaluable in determining ways to prevent future incidents from occurring. They provide good insight by determining root causes, into what failures occurred that lead to the incident.
Fairy forts are the remains of stone circles, ringforts, hillforts, or other circular prehistoric dwellings in Ireland. From (possibly) the late Iron Age to early Christian times, the island's occupants built circular structures with earth banks or ditches. These were sometimes topped with wooden palisades and wooden framed buildings. As the dwellings were not durable, only vague circular marks often remained in the landscape. The remains of these structures, in conjunction with the vegetation around them, are associated with local traditions and folklore, perhaps involving fairies or other supposed supernatural entities, who would "defend" the structures from destruction by builders or farmers.
The argument from reason is an argument against metaphysical naturalism and for the existence of God. The best-known defender of the argument is C. S. Lewis. Lewis first defended the argument at length in his 1947 book, Miracles: A Preliminary Study. In the second edition of Miracles (1960), Lewis substantially revised and expanded the argument.
Memory gaps and errors refer to the incorrect recall, or complete loss, of information in the memory system for a specific detail and/or event. Memory errors may include remembering events that never occurred, or remembering them differently from the way they actually happened. These errors or gaps can occur due to a number of different reasons, including the emotional involvement in the situation, expectations and environmental changes. As the retention interval between encoding and retrieval of the memory lengthens, there is an increase in both the amount that is forgotten, and the likelihood of a memory error occurring.
The vulnerability of nuclear plants to deliberate attack is of concern in the area of nuclear safety and security. Nuclear power plants, civilian research reactors, certain naval fuel facilities, uranium enrichment plants, fuel fabrication plants, and even potentially uranium mines are vulnerable to attacks which could lead to widespread radioactive contamination. The attack threat is of several general types: commando-like ground-based attacks on equipment which if disabled could lead to a reactor core meltdown or widespread dispersal of radioactivity; external attacks such as an aircraft crash into a reactor complex, or cyber attacks.
The Psychology of the Occult is a 1952 skeptical book on the paranormal by psychologist D. H. Rawcliffe. It was later published as Illusions and Delusions of the Supernatural and the Occult (1959) and Occult and Supernatural Phenomena (1988) by Dover Publications. Biologist Julian Huxley wrote a foreword to the book.
Is There a God? is a 1996 book by British philosopher of religion Richard Swinburne, claiming the existence of the Abrahamic God. The argument rests on an updated version of natural theology with biological evolution and Big Bang theory using scientific inference. In 2010, a revised version of the original book was released under the same title.
