Operation Luna
''Operation Luna'' is a science fantasy novel by American writer Poul Anderson, published in August 1999; it is the sequel to the 1971 fixup novel ''Operation Chaos'' by the same author. It centers around a space flight attempt and the efforts of Coyote and several Oriental antagonists to stop it. The IRS (Inquisition for Revenue Securement) and NASA (National Astral Spellcraft Administration) also become involved. The two main characters from ''Operation Chaos'', Steve Matuchek, a werewolf and engineer for Nornwell Scrytronics, and Virginia "Ginny" Matuchek continue in their fight against the forces of evil. Now married and in their 40s, they have three children—Val, the child they rescued from Hell in ''Operation Chaos'' when she was 3, now 14–15 years old; Ben, 10 years old; and Chryssa, 4 years old. A few characters from ''Operation Chaos'' also reappear, such as Barney Sturlason, Steve's boss, and Bob Shining Knife, a Native American F.B.I. agent, though they have small ...

Poul Anderson
Poul William Anderson (November 25, 1926 – July 31, 2001) was an American fantasy and science fiction author who was active from the 1940s until the 21st century. Anderson wrote also historical novels. His awards include seven Hugo Awards and three Nebula Awards. Biography Poul Anderson was born on November 25, 1926, in Bristol, Pennsylvania to Scandinavian parents. Soon after his birth, his father, Anton Anderson relocated the family to Texas, where they lived for more than ten years. After Anton Anderson's death, his widow took the children to Denmark. The family returned to the United States after the beginning of World War II, settling eventually on a Minnesota farm. While he was an undergraduate student at the University of Minnesota, Anderson's first stories were published by editor John W. Campbell in the magazine ''Astounding Science Fiction'': "Tomorrow's Children" by Anderson and F. N. Waldrop in March 1947 and a sequel, "Chain of Logic" by Anderson alone, in July ...

Yggdrasil
Yggdrasil (from Old Norse ), in Norse cosmology, is an immense and central sacred tree. Around it exists all else, including the Nine Worlds. Yggdrasil is attested in the ''Poetic Edda'' compiled in the 13th century from earlier traditional sources, and in the ''Prose Edda'' compiled in the 13th century by Snorri Sturluson. In both sources, Yggdrasil is an immense ash tree that is central to the cosmos and considered very holy. The gods go to Yggdrasil daily to assemble at their traditional governing assemblies, called things. The branches of Yggdrasil extend far into the heavens, and the tree is supported by three roots that extend far away into other locations; one to the well Urðarbrunnr in the heavens, one to the spring Hvergelmir, and another to the well Mímisbrunnr. Creatures live within Yggdrasil, including the dragon Níðhöggr, an unnamed eagle, and the stags Dáinn, Dvalinn, Duneyrr and Duraþrór. Scholars generally consider ''Hoddmímis holt'', ''Mímameiðr'' ...

Quantum Mechanics
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values ( quantization); objects have characteristics of both particles and waves (wave–particle duality); and there are limits to ...

Theory Of Relativity
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to the forces of nature. It applies to the cosmological and astrophysical realm, including astronomy. The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old Classical mechanics, theory of mechanics created primarily by Isaac Newton. It introduced concepts including 4-dimensional spacetime as a unified entity of space and time in physics, time, relativity of simultaneity, kinematics, kinematic and gravity, gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in ...

Max Planck
Max Karl Ernst Ludwig Planck (, ; 23 April 1858 – 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918. Planck made many substantial contributions to theoretical physics, but his fame as a physicist rests primarily on his role as the originator of quantum theory, which revolutionized human understanding of atomic and subatomic processes. In 1948, the German scientific institution Kaiser Wilhelm Society (of which Planck was twice president) was renamed Max Planck Society (MPG). The MPG now includes 83 institutions representing a wide range of scientific directions. Life and career Planck came from a traditional, intellectual family. His paternal great-grandfather and grandfather were both theology professors in Göttingen; his father was a law professor at the University of Kiel and Munich. One of his uncles was also a judge. Planck was born in 1858 in Kiel, Holstein, to Johann Julius Wilhelm Plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Special Pleading
Special pleading is an informal fallacy wherein one cites something as an exception to a general or universal principle, without justifying the special exception. It is the application of a double standard. In the classic distinction among material fallacies, cognitive fallacies, and formal fallacies, special pleading most likely falls within the category of a cognitive fallacy, because it would seem to relate to "lip service", rationalization, and diversion (abandonment of discussion). Special pleading also often resembles the "appeal to" logical fallacies. In medieval philosophy, it was not presumed that wherever a distinction is claimed, a relevant basis for the distinction should exist and be substantiated. Special pleading subverts a presumption of existential import. Examples A difficult case is when a possible criticism is made relatively immune to investigation. This immunity may take the forms of: * unexplained claims of exemption from principles commonly though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anasazi
The Ancestral Puebloans, also known as the Anasazi, were an ancient Native American culture that spanned the present-day Four Corners region of the United States, comprising southeastern Utah, northeastern Arizona, northwestern New Mexico, and southwestern Colorado. They are believed to have developed, at least in part, from the Oshara tradition, which developed from the Picosa culture. The people and their archaeological culture are often referred to as ''Anasazi'', meaning "ancient enemies", as they were called by Navajo. Contemporary Puebloans object to the use of this term, with some viewing it as derogatory. The Ancestral Puebloans lived in a range of structures that included small family pit houses, larger structures to house clans, grand pueblos, and cliff-sited dwellings for defense. They had a complex network linking hundreds of communities and population centers across the Colorado Plateau. They held a distinct knowledge of celestial sciences that found form in ...

Apache
The Apache () are a group of culturally related Native American tribes in the Southwestern United States, which include the Chiricahua, Jicarilla, Lipan, Mescalero, Mimbreño, Ndendahe (Bedonkohe or Mogollon and Nednhi or Carrizaleño and Janero), Salinero, Plains (Kataka or Semat or "Kiowa-Apache") and Western Apache ( Aravaipa, Pinaleño, Coyotero, Tonto). Distant cousins of the Apache are the Navajo, with whom they share the Southern Athabaskan languages. There are Apache communities in Oklahoma and Texas, and reservations in Arizona and New Mexico. Apache people have moved throughout the United States and elsewhere, including urban centers. The Apache Nations are politically autonomous, speak several different languages, and have distinct cultures. Historically, the Apache homelands have consisted of high mountains, sheltered and watered valleys, deep canyons, deserts, and the southern Great Plains, including areas in what is now Eastern Arizona, Northern Mexico ...

Chinese Mythology
Chinese mythology () is mythology that has been passed down in oral form or recorded in literature in the geographic area now known as Greater China. Chinese mythology includes many varied myths from regional and cultural traditions. Much of the mythology involves exciting stories full of fantastic people and beings, the use of magical powers, often taking place in an exotic mythological place or time. Like many mythologies, Chinese mythology has in the past been believed to be, at least in part, a factual recording of history. Along with Chinese folklore, Chinese mythology forms an important part of Chinese folk religion. Many stories regarding characters and events of the distant past have a double tradition: ones which present a more historicized or euhemerized version and ones which present a more mythological version. Many myths involve the creation and cosmology of the universe and its deities and inhabitants. Some mythology involves creation myths, the origin of things, ...
