Author
In legal discourse, an author is the creator of an original work that has been published, whether that work exists in written, graphic, visual, or recorded form. The act of creating such a work is referred to as authorship. Therefore, a sculptor, painter, or composer is considered the author of their respective sculptures, paintings, or musical compositions. Although in common usage, the term "author" is often associated specifically with the writer of a book, Article (publishing), article, Play (theatre), play, or other written work. In cases involving a work for hire, the employer or commissioning party is legally considered the author of the work, even if it was created by someone else. Typically, the first owner of a copyright is the creator of the copyrighted work, i.e., the author. If more than one person created the work, then joint authorship has taken place. Copyright laws differ around the world. The United States Copyright Office, for example, defines copyright as "a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhysling Awards
__NOTOC__ The Rhysling Awards are an annual award given for the best science fiction, fantasy, or horror poem of the year. The award name was dubbed by Andrew Joron in reference to a character in a science fiction story: the blind poet Rhysling, in Robert A. Heinlein's short story "The Green Hills of Earth".David Langford"Rhysling Award."''The Encyclopedia of Science Fiction'', 3rd edition (online). Ed. John Clute, David Langford, and Peter Nicholls. 2013. Accessed 19 February 2013 The award is given in two categories: "Best Long Poem", for works of 50 or more lines, and "Best Short Poem", for works of 49 or fewer lines. The nominees for each year's Rhysling Awards are chosen by the members of the Science Fiction Poetry Association (SFPA). Each member may nominate one work for each of the categories. Until 2022, all nominated works were compiled into an anthology called '' The Rhysling Anthology'', and members of the Association would then vote on the final winners. In 2022, the p ...

Hugo Awards
The Hugo Award is an annual literary award for the best science fiction or fantasy works and achievements of the previous year, given at the World Science Fiction Convention (Worldcon) and chosen by its members. The award is administered by the World Science Fiction Society. It is named after Hugo Gernsback, the founder of the pioneering science fiction magazine ''Amazing Stories''. Hugos were first given in 1953, at the 11th World Science Fiction Convention, and have been awarded every year since 1955. In 2010, ''Wired'' called the Hugo "the premier award in the science fiction genre", while ''The Guardian'' has called it the most important science fiction award alongside the Nebula Award. The awards originally covered seven categories, but have expanded to seventeen categories of written and dramatic works over the years. The winners receive a trophy consisting of a stylized rocket ship on a base. The design of the trophy changes each year, though the rocket shape has bee ...

LexisNexis
LexisNexis is an American data analytics company headquartered in New York, New York. Its products are various databases that are accessed through online portals, including portals for computer-assisted legal research (CALR), newspaper search, and consumer information. During the 1970s, LexisNexis began to make legal and journalistic documents more accessible electronically. the company had the world's largest electronic database for legal and public-records–related information. The company is a subsidiary of RELX. History LexisNexis is owned by RELX (formerly known as Reed Elsevier). According to Trudi Bellardo Hahn and Charles P. Bourne, LexisNexis (originally founded as LEXIS) is historically significant because it was the first of the early information services to both envision and actually bring about a future in which large populations of end users would directly interact with computer databases, rather than going through professional intermediaries like librari ...

Hard Science Fiction
Hard science fiction is a category of science fiction characterized by concern for scientific accuracy and logic. The term was first used in print in 1957 by P. Schuyler Miller in a review of John W. Campbell's ''Islands of Space'' in the November issue of ''Astounding Science Fiction''. The complementary term ''soft science fiction'', formed by analogy to the popular distinction between the "hard" (natural science, natural) and "soft" (social science, social) sciences,) first appeared in the late 1970s. Though there are examples generally considered as Hard and soft science, "hard" science fiction such as Isaac Asimov's Foundation (book series), ''Foundation'' series, built on mathematical sociology, science fiction critic Gary Westfahl argues that while neither term is part of a rigorous Taxonomy (general), taxonomy, they are approximate ways of characterizing stories that reviewers and commentators have found useful. History Stories revolving around scientific and technical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venus
Venus is the second planet from the Sun. It is often called Earth's "twin" or "sister" planet for having almost the same size and mass, and the closest orbit to Earth's. While both are rocky planets, Venus has an atmosphere much thicker and denser than Earth and any other rocky body in the Solar System. Its atmosphere is composed of mostly carbon dioxide (), with a global sulfuric acid cloud cover and no liquid water. At the mean surface level the atmosphere reaches a temperature of and a pressure 92 times greater than Earth's at sea level, turning the lowest layer of the atmosphere into a supercritical fluid. Venus is the third brightest object in Earth's sky, after the Moon and the Sun, and, like Mercury, appears always relatively close to the Sun, either as a "morning star" or an "evening star", resulting from orbiting closer ( inferior) to the Sun than Earth. The orbits of Venus and Earth make the two planets approach each other in synodic periods of 1.6 years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars
Mars is the fourth planet from the Sun. It is also known as the "Red Planet", because of its orange-red appearance. Mars is a desert-like rocky planet with a tenuous carbon dioxide () atmosphere. At the average surface level the atmospheric pressure is a few thousandths of Earth's, atmospheric temperature ranges from and cosmic radiation is high. Mars retains some water, in the ground as well as thinly in the atmosphere, forming cirrus clouds, frost, larger polar regions of permafrost and ice caps (with seasonal snow), but no liquid surface water. Its surface gravity is roughly a third of Earth's or double that of the Moon. It is half as wide as Earth or twice the Moon, with a diameter of , and has a surface area the size of all the dry land of Earth. Fine dust is prevalent across the surface and the atmosphere, being picked up and spread at the low Martian gravity even by the weak wind of the tenuous atmosphere. The terrain of Mars roughly follows a north-south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the List of Solar System objects by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Cells
A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect.Solar Cells chemistryexplained.com It is a type of photoelectric cell, a device whose electrical characteristics (such as current, , or resistance) vary when it is exposed to light.

Photovoltaics
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation does not generate any pollution or any greenhouse gas emissions; it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required ...

Solar Power
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics (PV) were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar panels has fallen, grid-connected solar PV systems' capacity and production has doubled about every three years. Three-quarters of new generation capacity is solar, with both millions of rooftop installatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
