Informatics is the science of information, the practice of information processing, and the engineering of information systems. Informatics studies the structure, algorithms, behavior, and interactions of natural and artificial systems that store, process, access and communicate information. It also develops its own conceptual and theoretical foundations and utilizes foundations developed in other fields. Since the advent of computers, individuals and organizations increasingly process information digitally. This has led to the study of informatics that had computational, cognitive and social aspects, including study of the social impact of information technologies.
In some situations, information science and informatics are used interchangeably. However, some consider information science to be a subarea of the more general field of informatics.
Used as a compound, in conjunction with the name of a discipline, as in medical informatics, bioinformatics, etc., it denotes the specialization of informatics to the management and processing of data, information and knowledge in the named discipline, and the incorporation of informatic concepts and theories to enrich the other discipline; it has a similar relationship to library science.

Kratocracy, from (Gr. krateros, strong), is according to Montague, government by those who are strong enough to seize power through force or cunning. The term was also used by Kropotkin in Mutual Aid: A Factor of Evolution, but is now rarely seen.
It is technically the most basic type of governing body, proven to have gone back right to the original human Tribes. It is from this simple philosophy of Authority of the fittest that other forms of government have stemmed.

The name Parseval, from August von Parseval, was used between 1909 and 1919 to denote 22 airships built by the Luft-Fahrzeug-Gesellschaft (LFG) following his design. Later several airships were built following the Parseval-Naatz design.
Earlier, the airships were written of using the masculine form. That is, in German, "der Parseval" was written, similar to der Zeppelin.

A barbican (from medieval Latin barbecana, "outer fortification of a city or castle," a general Romanic word, perhaps from Arabic or Persian cf. bab-khanah "gate-house" and "towered gateway" or from the mediaeval English burgh-kenning ) is a fortified outpost or gateway, such as an outer defense to a city or castle, or any tower situated over a gate or bridge which was used for defensive purposes. Usually barbicans were situated outside the main line of defences and connected to the city walls with a walled road called the neck.

Radioresistance is surprisingly high in many organisms, in contrast to previously held views. For example, the study of environment, animals and plants around the Chernobyl accident area has revealed an unexpected survival of many species, despite the high radiation levels. A Brazilian study in a hill in the state of Minas Gerais which has high natural radiation levels from uranium deposits, has also shown many radioresistant insects, worms and plants.

Permaculture is an approach to designing human settlements and perennial agricultural systems that mimic the relationships found in the natural ecologies. It was first developed by Australians Bill Mollison and David Holmgren and their associates during the 1970s in a series of publications. The word permaculture is a portmanteau of permanent agriculture, as well as permanent culture.

Hexspeak was created by programmers who wanted a magic number, a clear and unique identifier with which to mark memory or data. Using hexadecimal notation, which includes the digits 0123456789ABCDEF, it is possible to create small words with the digit "0" representing the letter "O", "1" representing the letter "I", and "5" representing "S".

A Gulet is a traditional design of a two-masted wooden sailing vessel from the south-west coast of Turkey, although similar vessels can be found all around the eastern Mediterranean. Today this type of vessel, varying in size from 14 to 35 metres, is now very popular for tourist charters although, for considerations of crew economy, diesel power is now almost universally used and many are not properly rigged for sailing.

A set of chemical reactions can be said to be "collectively autocatalytic" if a number of those reactions produce, as reaction products, catalysts for enough of the other reactions that the entire set of chemical reactions is self sustaining given an input of energy and food molecules (see autocatalytic set).

The patterns of species distribution at this level can usually be explained through a combination of historical factors such as speciation, extinction, continental drift, glaciation (and associated variations in sea level, river routes, and so on), and river capture, in combination with the area and isolation of landmasses (geographic constraints) and available energy supplies.
