Erin Macdonald
Erin Macdonald is an astrophysicist, aerospace engineer, and science fiction consultant. She hosts the YouTube channel, Dr. Erin Explains the Universe, teaches STEM through popular culture, and consults with science fiction creators. Education and early career Macdonald credits fictional characters such as Dana Scully and Kathryn Janeway (the latter of whom she even acknowledges in her Ph.D. dissertation) with providing the inspiration to pursue a science career. She earned her bachelor's degrees in astrophysics and mathematics at the University of Colorado Boulder (after transferring there from the University of New Mexico) and her Ph.D. at the University of Glasgow, where she concentrated in general relativity. Macdonald did post-doctoral work with the Laser Interferometer Gravitational-Wave Observatory (LIGO) collaboration as part of an attempt to detect gravitational waves from the Crab Pulsar. She also did post-doctoral work at Cardiff University, still with LIGO, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravitational Wave
Gravitational waves are waves of the intensity of gravity generated by the accelerated masses of an orbital binary system that propagate as waves outward from their source at the speed of light. They were first proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as waves similar to electromagnetic waves but the gravitational equivalent. Gravitational waves were later predicted in 1916 by Albert Einstein on the basis of his general theory of relativity as ripples in spacetime. Later he refused to accept gravitational waves. Gravitational waves transport energy as gravitational radiation, a form of radiant energy similar to electromagnetic radiation. Newton's law of universal gravitation, part of classical mechanics, does not provide for their existence, since that law is predicated on the assumption that physical interactions propagate instantaneously (at infinite speed)showing one of the ways the methods of Newtonian physics are unable to explain p ...

Spacetime
In physics, spacetime is a mathematical model that combines the three dimensions of space and one dimension of time into a single four-dimensional manifold. Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive differently where and when events occur. Until the 20th century, it was assumed that the three-dimensional geometry of the universe (its spatial expression in terms of coordinates, distances, and directions) was independent of one-dimensional time. The physicist Albert Einstein helped develop the idea of spacetime as part of his theory of relativity. Prior to his pioneering work, scientists had two separate theories to explain physical phenomena: Isaac Newton's laws of physics described the motion of massive objects, while James Clerk Maxwell's electromagnetic models explained the properties of light. However, in 1905, Einstein based a work on special relativity on two postulates: * The laws of physics are invari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fandom
A fandom is a subculture composed of fans characterized by a feeling of empathy and camaraderie with others who share a common interest. Fans typically are interested in even minor details of the objects of their fandom and spend a significant portion of their time and energy involved with their interest, often as a part of a social network with particular practices, differentiating fandom-affiliated people from those with only a casual interest. A fandom can grow around any area of human interest or activity. The subject of fan interest can be narrowly defined, focused on something like an individual celebrity, or encompassing entire hobbies, genres or fashions. While it is now used to apply to groups of people fascinated with any subject, the term has its roots in those with an enthusiastic appreciation for sports. Merriam-Webster's dictionary traces the usage of the term back as far as 1903. Many fandoms overlap. There are a number of large conventions that cater to fando ...

Science Fiction Convention
Science fiction conventions are gatherings of fans of the speculative fiction genre, science fiction. Historically, science fiction conventions had focused primarily on literature, but the purview of many extends to such other avenues of expression as films, television, comics, animation, and games. The format can vary but will tend to have a few similar features such as a guest of honour, discussion panels, readings and large special events such as opening/closing ceremonies and some form of party or entertainment. Science fiction conventions started off primarily in the UK and US but have now spread further and several countries have their own individual conventions as well as playing host to rotating international conventions. History The precise time and place of the first science fiction convention is a matter of some dispute. The idea and form was clearly anticipated in Robert Bloch's short story about a large convention of writers, "The Ultimate Ultimatum" (''Fantasy ...

Science Fiction
Science fiction (sometimes shortened to Sci-Fi or SF) is a genre of speculative fiction which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, extraterrestrial life, sentient artificial intelligence, cybernetics, certain forms of immortality (like mind uploading), and the singularity. Science fiction predicted several existing inventions, such as the atomic bomb, robots, and borazon, whose names entirely match their fictional predecessors. In addition, science fiction might serve as an outlet to facilitate future scientific and technological innovations. Science fiction can trace its roots to ancient mythology. It is also related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers. Science fiction, in literature, film, television, and other media, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erin Macdonald At Starbase Indy 2019
Erin is a Hiberno-English word for Ireland originating from the Irish word ''"Éirinn"''. "Éirinn" is the dative case of the Irish word for Ireland, "Éire", genitive "Éireann", the dative being used in prepositional phrases such as ''"go hÉirinn"'' "to Ireland", ''"in Éirinn"'' "in Ireland", ''"ó Éirinn''" "from Ireland". The dative has replaced the nominative in a few regional Irish dialects (particularly Galway-Connemara and Waterford). Poets and nineteenth-century Irish nationalists used ''Erin'' in English as a romantic name for Ireland. Often, "Erin's Isle" was used. In this context, along with Hibernia, Erin is the name given to the female personification of Ireland, but the name was rarely used as a given name, probably because no saints, queens, or literary figures were ever called Erin. According to Irish mythology and folklore, the name was originally given to the island by the Milesians after the goddess ''Ériu''. The phrase Erin go bragh ("Éire go br ...

Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space R ...
