The Third Gate
The American author Lincoln Child has released a number of novels and works. Stand-alone novels Utopia (2002) ''Utopia'' is the first solo novel by Lincoln Child, published in 2002. It is set in a futuristic amusement park called ''Utopia'', a park that relies heavily on holographics and robotics. Dr. Andrew Warne, the man who designed the program that runs the park's robots, is called in to help fix a problem. But when he gets there, he finds out that the park is being held hostage by a mysterious man known as John Doe. Utopia consists of five "Worlds", each modeled after different time eras. *The Nexus: A neutral setting between the Worlds. *Gaslight: Based on Victorian London. *Camelot: A medieval kingdom. *Boardwalk: A reproduction of a sea side amusement park. *Callisto: A futuristic spaceport above Jupiter's sixth moon. *Atlantis: A water park based on the lost continent of Atlantis (in the novel, Atlantis is still under construction, and is seen in the epilogue).

Lincoln Child
Lincoln Child (born October 13, 1957) is an American author of techno-thriller and horror novels. Though he is most well known for his collaborations with Douglas Preston (including the Agent Pendergast series and the Gideon Crew series, among others), he has also written eight solo novels, including the Jeremy Logan series. Over twenty of the collaborative novels and most of his solo novels have become New York Times bestsellers, some reaching the #1 position. Child and Preston's first novel together, ''Relic'', was adapted into a feature film. Their books are notable for their thorough research and scientific accuracy. Life and career Born in Westport, Connecticut, but now a Florida resident, Child graduated from Carleton College in Northfield, Minnesota, with a major in English. Soon afterward, in 1979, he secured a job as an editorial assistant at St. Martin's Press. By 1984, Child had become full editor. While in this position, he edited hundreds of books, most titles be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Force Microscopy
Magnetic force microscopy (MFM) is a variety of atomic force microscopy, in which a sharp magnetized tip scans a magnetic sample; the tip-sample magnetic interactions are detected and used to reconstruct the magnetic structure of the sample surface. Many kinds of magnetic interactions are measured by MFM, including magnetic dipole–dipole interaction. MFM scanning often uses non-contact atomic force microscopy (NC-AFM) and is considered to be non-destructive with respect to the test sample. In MFM, the test sample(s) do not need to be electrically conductive to be imaged. Overview In MFM measurements, the magnetic force between the test sample and the tip can be expressed as :\vec F=\mu_o (\vec m \cdot \nabla ) \vec H \,\! where \vec m \, \! is the magnetic moment of the tip (approximated as a point dipole), \vec H \, \! is the magnetic stray field from the sample surface, and ''μ0'' is the magnetic permeability of free space. Because the stray magnetic field from the sample ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Fox
The Arctic fox (''Vulpes lagopus''), also known as the white fox, polar fox, or snow fox, is a small species of fox native to the Arctic regions of the Northern Hemisphere and common throughout the Tundra#Arctic tundra, Arctic tundra biome. It is well adaptation, adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. It has a large and very fluffy tail. In the wild, most individuals do not live past their first year but some exceptional ones survive up to 11 years. Its body length ranges from , with a generally rounded body shape to minimize the escape of body heat. The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. It also eats carrion, berries, seaweed, and insects and other small invertebrates. Arctic foxes form Monogamy in animals, monogamous pairs during the breeding season and they stay together to raise their young in complex underground dens. ...

Dorset Culture
The Dorset was a Paleo-Eskimo culture, lasting from to between and , that followed the Pre-Dorset and preceded the Thule people (proto-Inuit) in the North American Arctic. The culture and people are named after Cape Dorset (now Kinngait) in Nunavut, Canada, where the first evidence of its existence was found. The culture has been defined as having four phases due to the distinct differences in the technologies relating to hunting and tool making. Artifacts include distinctive triangular end-blades, oil lamps ( qulliq) made of soapstone, and burins. The Dorset were first identified as a separate culture in 1925. The Dorset appear to have been extinct by 1500 at the latest and perhaps as early as 1000. The Thule people, who began migrating east from Alaska in the 11th century, ended up spreading through the lands previously inhabited by the Dorset. It is not fully known whether the Inuit and Dorset ever met. Some modern genetic studies show the Dorset population were distinct ...

Ice Cave
An ice cave is any type of natural cave (most commonly lava tubes or limestone caves) that contains significant amounts of perennial (year-round) ice. At least a portion of the cave must have a temperature below 0 °C (32 °F) all year round, and water must have traveled into the cave’s cold zone. Terminology This type of cave was first formally described by Englishman Edwin Swift Balch in 1900, who suggested the French term ''glacieres'' should be used for them, even though the term ''ice cave'' was then, as now, commonly used to refer to caves simply containing year-round ice. Among speleologists, ''ice cave'' is the proper English term. A cavity formed ''within'' ice (as in a glacier) is properly called a glacier cave. Types Ice caves occur as static ice caves, such as Peña Castil Ice Cave, and dynamic or cyclical ice caves, such as Eisriesenwelt. Temperature mechanisms In most of the world, bedrock caves are thermally insulated from the surface and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Tube
A lava tube, more rarely called a pyroduct, is a 'roofed conduit through which molten lava travels away from its vent'. If lava in the tube drains out, it will leave an empty cave. Lava tubes are common in low-viscosity volcanic systems. Lava tubes are important as they are able to transport molten lava much further away from the eruptive vent than lava channels. A tube-forming lava flow can emplace on longer distance due to the presence of a solid crust protecting the molten lava from atmospheric cooling. Lava tubes are often considered when preparing hazard maps or managing an eruptive crisis. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Three main formation mechanisms have been described: (1) roofing over a lava channel, (2) pāhoehoe lobe extension or (3) lava flow inflation. # When it erupts from a vent, lava usually flow ...

Smilodon
''Smilodon'' is an extinct genus of Felidae, felids. It is one of the best known saber-toothed predators and prehistoric mammals. Although commonly known as the saber-toothed tiger, it was not closely related to the tiger or other modern cats, belonging to the extinct subfamily Machairodontinae, with an estimated date of Speciation, divergence from the ancestor of living cats around 20 million years ago. ''Smilodon'' was one of the last surviving machairodonts alongside ''Homotherium''. ''Smilodon'' lived in the Americas during the Pleistocene to early Holocene epoch (2.5 Year#mya, mya – at latest 8,200 years ago). The genus was named in 1842 based on fossils from Brazil; the generic name means or combined with . Three species are recognized today: ''S. gracilis'', ''S. fatalis'', and ''S. populator''. The two latter species were probably descended from ''S. gracilis'', which itself probably evolved from ''Megantereon''. The hundreds of specimens obtained from the La Brea T ...

Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual Cell (biology), cell, a multicellular organism, or a Community (ecology), community of Biological interaction, interacting populations. They usually specialize in a particular Outline of biology#Subdisciplines, branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypothesis, hypotheses. Their discoveries may have Applied science#Applied research, applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climatology
Climatology (from Greek , ''klima'', "slope"; and , '' -logia'') or climate science is the scientific study of Earth's climate, typically defined as weather conditions averaged over a period of at least 30 years. Climate concerns the atmospheric condition during an extended to indefinite period of time; weather is the condition of the atmosphere during a relative brief period of time. The main topics of research are the study of climate variability, mechanisms of climate changes and modern climate change. This topic of study is regarded as part of the atmospheric sciences and a subdivision of physical geography, which is one of the Earth sciences. Climatology includes some aspects of oceanography and biogeochemistry. The main methods employed by climatologists are the analysis of observations and modelling of the physical processes that determine climate. Short term weather forecasting can be interpreted in terms of knowledge of longer-term phenomena of climate, for insta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleoecology
Paleoecology (also spelled palaeoecology) is the study of interactions between organisms and/or interactions between organisms and their environments across geologic timescales. As a discipline, paleoecology interacts with, depends on and informs a variety of fields including paleontology, ecology, climatology and biology. Paleoecology emerged from the field of paleontology in the 1950s, though paleontologists have conducted paleoecological studies since the creation of paleontology in the 1700s and 1800s. Combining the investigative approach of searching for fossils with the theoretical approach of Charles Darwin and Alexander von Humboldt, paleoecology began as paleontologists began examining both the ancient organisms they discovered and the reconstructed environments in which they lived. Visual depictions of past marine and terrestrial communities have been considered an early form of paleoecology. The term "paleo-ecology" was coined by Frederic Clements in 1916. Overview of ...

Effects Of Global Warming
Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall warming trend, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires, thawing permafrost, and desertification. These changes impact ecosystems and societies, and can become irreversible once tipping points are crossed. Climate activists are engaged in a range of activities around the world that seek to ameliorate these issues or prevent them from happening. The effects of climate change vary in timing and location. Up until now the Arctic has warmed faster than most other regions due to climate change feedbacks. Surface air temperatures over land have also increased at about twice the rate they do over the ocean, causing intense heat waves. These temperatures would stabilize if greenhouse gas emissions ...

Arctic Circle
The Arctic Circle is one of the two polar circles, and the northernmost of the five major circle of latitude, circles of latitude as shown on maps of Earth at about 66° 34' N. Its southern counterpart is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the winter solstice in the Northern Hemisphere, the Sun does not rise all day, and on the Northern Hemisphere's summer solstice, the Sun does not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more obvious this becomes. For example, in the Russian port city of Murmansk, three degrees north of the Arctic Circle, the Sun stays below the horizon for 20 days before and after the winter solstice, and above the horizon for 20 days before and after the summer solstice. The position of the Arctic Circle is not fixed and currently runs north of the Equator. Its latitude depends on Earth's axial tilt, which axial precession, ...
