Research Assistant
A research assistant (RA) is a researcher employed, often on a temporary contract, by a university, a research institute or a privately held organization, for the purpose of assisting in academic or private research. Research assistants are not independent and are responsible to a supervisor or principal investigator and usually are not directly responsible for the outcome of the research. However, in some countries, research assistants can be the main contributor to the outcome of the research. Research assistants are often educated to degree level and might be enrolled in a postgraduate degree program and simultaneously teach, for example, if enrolled in a PhD programme they are known as Doctoral Research Assistants. Undergraduate and post-doctoral level Although a research assistant is normally appointed at graduate level, undergraduates are also sometimes appointed to support research. In Economics and Business, for instance, numerous research assistantship opportunities are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Conversation (website)
''The Conversation'' is a network of not-for-profit media outlets publishing news stories and research reports online, with accompanying expert opinion and analysis. Articles are written by academics and researchers under a free Creative Commons license, allowing reuse without modification. Its model has been described as explanatory journalism.

Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "spac ...

How It Works (magazine)
Imagine Publishing was a UK-based magazine publisher, which published a number of video games, computing, creative and lifestyle magazines. It was founded on 14 May 2005 with private funds by Damian Butt, Steven Boyd and Mark Kendrick, all were former directors of Paragon Publishing, and launched with a core set of six gaming and creative computing titles in the first 6 months of trading. It was taken over by Future plc on 21 October 2016. In October 2005, it had acquired the only retro games magazine Retro Gamer, after its original publisher, Live Publishing went bankrupt. Early in 2006, it further acquired the rights to publish a considerable number of titles including gamesTM, Play, PowerStation, X360, Digital Photographer and iCreate, from the old Paragon Publishing stable of magazines when owner Highbury House Communications went into liquidation, following Future Publishing's withdrawal of its offer to buy the company, due to threats of a monopoly-investigation by the ...

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many famous scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which in turn is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large format newspaper was released August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found ...

Hydrodynamical
In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids—liquids and gases. It has several subdisciplines, including ''aerodynamics'' (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves the calculation of various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time.

Exoplanet
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003. There are many methods of detecting exoplanets. Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational bias favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tidal locking zone. In several cases, multiple planets have been observed around a star. About 1 in 5 Sun-like starsFor the purpose of this 1 in 5 statistic, "Sun-like" means G-type star.

Computer Simulation
Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict. Computer simulations have become a useful tool for the mathematical modeling of many natural systems in physics (computational physics), astrophysics, climatology, chemistry, biology and manufacturing, as well as human systems in economics, psychology, social science, health care and engineering. Simulation of a system is represented as the running of the system's model. It can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions. Computer simulations are realized by running computer programs that can be either small, running almost instantly on small devices, or large ...

Disc Galaxy
A disc galaxy (or disk galaxy) is a galaxy characterized by a galactic disc, a flattened circular volume of stars. These galaxies may or may not include a central non-disc-like region (a galactic bulge). Disc galaxy types include: * Spiral galaxies: ** Unbarred spiral galaxies: (types S, SA) ** Barred spiral galaxies: (type SB) ** Intermediate spiral galaxies: (type SAB) * Lenticular galaxies: (types E8, S0, SA0, SB0, SAB0) Galaxies that are not disc types include: * Elliptical galaxies: (type dE) * Irregular galaxies: (type dI) See also * thick disk * thin disk The thin disk is a structural component of spiral and S0-type galaxies, composed of stars, gas and dust. It is the main non-centre (e.g. galactic bulge) density, of such matter. That of the Milky Way is thought to have a scale height of around ...
