Bolide from the French astronomy book Le Ciel; Notions 'Elémentaires d'Astronomie Physique (1877). The word bolide (/ ˈ b oʊ l aɪ d /; from Italian via Latin, from Ancient Greek βολίς (bolís) 'missile' [2] [3]) may refer to somewhat different phenomena depending on the context in which the word appears, and readers may need to make inferences to determine which meaning is intended in ...
Asteroid impacts: one large impact is associated with a mass extinction, that is, the Cretaceous–Paleogene extinction event; there have been many smaller impacts but they are not associated with significant extinctions, [105] or cannot be dated precisely enough.
When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, as the impacting body is usually traveling at several kilometres a second (a minimum of 11.2 km/s (7.0 mi/s) for an Earth impacting body [2]), though atmospheres mitigate many surface impacts through atmospheric entry.
"It's clear from the devastation caused by the current wildfires in LA that rapid changes in the volatility of precipitation and evaporation can have a large impact," said Prof Sir Brian Hoskins ...
Taleb's "black swan theory" (which differs from the earlier philosophical versions of the problem) refers only to statistically unexpected events of large magnitude and consequence and their dominant role in history. Such events, considered extreme outliers, collectively play vastly larger roles than regular occurrences.
Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
fault tree. A cascade effect is an inevitable and sometimes unforeseen chain of events due to an act affecting a system. [1] If there is a possibility that the cascade effect will have a negative impact on the system, it is possible to analyze the effects with a consequence / impact analysis.
In the summer of 1998, Hollywood offered up not one, but two blockbuster films about asteroids hurtling towards Earth. Released on May 8 of that year, Deep Impact, directed by Mimi Leder, told a ...
