Natural nuclear fission reactor Geological situation in Gabon leading to natural nuclear fission reactors 1. Nuclear reactor zones 2. Sandstone 3. Uranium ore layer 4. A natural nuclear fission reactor is a uranium deposit where self-sustaining nuclear chain reactions have occurred. History[edit] In May 1972 at the Pierrelatte uranium enrichment facility in France, routine mass spectrometry comparing UF6 samples from the Oklo Mine, located in Gabon, Central Africa, showed a discrepancy in the amount of the 235U isotope. This loss in 235U is exactly what happens in a nuclear reactor. Fission product isotope signatures[edit] Neodymium[edit] Isotope signatures of natural neodymium and fission product neodymium from 235U which had been subjected to thermal neutrons. Neodymium and other elements were found with isotopic compositions different from what is customarily found on Earth. Ruthenium[edit] Isotope signatures of natural ruthenium and fission product ruthenium from 235U which had been subjected to thermal neutrons.
Nietzsche: Genealogy of Morals | Fewer Lacunae Nietzsche: Genealogy of Morals Here, I read through Nietzsche’s text Genealogy of Morals, compressing each aphorism into one sentence. While obviously such a task cannot capture all of Nietzsche’s genius, for me it retained enough of its vigor to feel worthwhile. Preface Context Of This Work Man is singularly ignorant of his inner nature.The mind of a philosopher is like a tree: their ideas have depth and are never produced in isolation.My answers to the title subject have grown into a secret wealth of knowledge – a garden.Other incompetent works spurred my publishing, and my theories have matured with my work. Goals Of This Work I seek to supplant nihilism, pity, and those who would say “No” to life.We must unearth the motivators of moral systems, we must valuate values: what if our morality constrains our greatness? Good & Evil, Good & Bad Introduction Why do English psychologists pursue that which is shameful? Morality As An Expression Of Power The Birth Of Slave Morality Conclusion Like this:
Feedback loops: How nature gets its rhythms - Anje-Margriet Neutel | TED-Ed The music in this lesson was composed by Ross Allchurch. Feedback What is feedback? Feedbacks affect the way every single variable, every population in an ecosystem for example, responds to both internal and external perturbations. That is what happens with feedbacks in an ecosystem as well, it is all about the combination of feedbacks. Learn more about how feedbacks work, about positive feedbacks in natural systems, and the relation between feedback and system stability.Ecological networks Natural communities do not consist of simple food chains, they are complex networks of interactions. What will happen to a food web when we hunt big predators to extinction? To learn more about chains of interactions in complex ecological networks, watch the TED-Ed Lessons about the extinction of big predators, pollination by honeybees, and detritus.Measuring the feedbacks in real systems
10 Massive Things We Built And Then Destroyed Technology When the first modern human built the first permanent structure, it was fated that a rival would not rest until he had erected a larger one. We love big things, we’re fascinated with huge things, and we’re left in awe of massive things. But sometimes even the most massive of man-made objects becomes lost to time because of disaster or necessity. 10The Great Wheel Sure mankind loves big things, but we also love fun. The grandest of all fairs in the world are the aptly named World’s Fairs; the Eiffel Tower was constructed specifically for the 1889 World’s Fair in Paris. While the Ferris Wheel might seem commonplace in today’s world of advanced engineering, the competition to build the largest Ferris Wheel still remains heated. Built for the Empire of India exhibition, it stood a mammoth 94 meters (308 ft) tall and could carry 40 passengers in a single car (it also had 40 cars). 9SS Great Eastern 8Tsar Tank 7The Crystal Palace 6Big Muskie Big Muskie didn’t move via treads or wheels.
Largest organisms The largest organisms found on Earth can be determined according to various aspects of organisms size, such as: mass, volume, area, length, height, or even genome size. Some organisms group together to form a superorganism, but such are not classed as single large organisms. The Great Barrier Reef is the world's largest structure composed of living entities, stretching 2,000 km, but contains many organisms of many species. Plants[edit] The largest single-stem tree by wood volume and mass is the giant sequoia (Sequoiadendron giganteum), native to Sierra Nevada and California; it grows to an average height of 70–85 m (230–280 ft) and 5–7 m (16–23 ft) in diameter. Multiple-stem trees such as Banyan can be enormous. Animals[edit] The blue whale is the heaviest animal ever known to have existed. A member of the order Cetacea, the blue whale (Balaenoptera musculus), is believed to be the largest animal ever to have lived. Table of heaviest living animals Table of heaviest terrestrial animals
Extremes on Earth This article describes extreme locations on Earth. Entries listed in bold are Earth-wide extremes. Extreme elevations and temperatures per continent[edit] Greatest vertical drop[edit] Subterranean[edit] Greatest oceanic depths[edit] Deepest ice[edit] Ice sheets on land, but having the base below sea level. Coldest and hottest inhabited places on Earth[edit] Northern and southernmost points of land on Earth[edit] See also[edit] References[edit] External links[edit] List of weather records This is a list of weather records, a list of the most extreme occurrences of weather phenomena for various categories. Many weather records are measured under specific conditions—such as surface temperature and wind speed—to keep consistency among measurements around the Earth. Each of these records is understood to be the record value officially observed, as these records may have been exceeded before modern weather instrumentation was invented, or in remote areas without an official weather station. Temperature[edit] The standard measuring conditions for temperature are two meters above the ground, and shielded from direct sunlight (hence the term, x degrees "in the shade"). Heat[edit] Highest temperatures ever recorded[edit] A world map showing areas with KöppenBWh (hot desert climate). *Temperature reached on multiple occasions; this is the most recent. ‡On 16 January 1889, a temperature of 53 °C (128 °F) was recorded at Cloncurry, Queensland. Other high-temperature records[edit]
Laughter in animals Laughter in animals other than humans describes animal behavior which resembles human laughter. Numerous species demonstrate vocalizations similar to human laughter. A significant proportion of these are mammals, including non-human primates, which suggests that the neurological functions involved in expressing cheer occurred early in the process of mammalian evolution. [1] Non-human primates[edit] Chimpanzees, gorillas, bonobos and orangutans show laughter-like vocalizations in response to physical contact, such as wrestling, play chasing, or tickling. This is documented in wild and captive chimpanzees. Research has noted the similarity in forms of laughter among humans and apes (chimpanzees, bonobos, gorillas, orangutans) when tickled, suggesting that laughter derived from a common origin among primate species, and has subsequently evolved prior to the origin of humans.[2][3] Rats[edit] Dogs[edit] A dog laugh sounds similar to a normal pant.
