Martial artsMartial arts are codified systems and traditions of combat practiced for a number of reasons such as self-defense; military and law enforcement applications; competition; physical, mental, and spiritual development; entertainment; and the preservation of a nation's intangible cultural heritage. Martial arts is an English translation of the Japanese word "武芸 bu-gei". Literally, it refers to "武 martial" and "芸 arts".
Indian martial artsIndian martial arts refers to the fighting systems of the Indian subcontinent. A variety of terms are used for the English phrases "Indian martial arts", deriving from ancient sources. While they may seem to imply specific disciplines (e.g. archery, armed combat), by Classical times they were used generically for all fighting systems. Among the most common terms today, śastra-vidyā, is a compound of the words (weapon) and (knowledge).
Chinese martial artsChinese martial arts, often called by the umbrella terms kung fu (ˈkʌŋ_ˈfuː; ), kuoshu () or wushu (), are multiple fighting styles that have developed over the centuries in Ancient China . These fighting styles are often classified according to common traits, identified as "families" of martial arts. Examples of such traits include Shaolinquan () physical exercises involving All Other Animals () mimicry or training methods inspired by Old Chinese philosophies, religions and legends.
Japanese martial artsJapanese martial arts refers to the variety of martial arts native to the country of Japan. At least three Japanese terms (budō, bujutsu, and bugei) are used interchangeably with the English phrase Japanese martial arts. The usage of the term budō (武道) to mean martial arts is a modern one: historically the term meant a way of life encompassing physical, spiritual and moral dimensions with a focus on self-improvement, fulfillment or personal growth. The terms bujutsu (武術) and bugei (武芸) have different meanings from budō, at least historically speaking.
Mixed martial artsMixed martial arts (MMA) is a full-contact combat sport based on striking, grappling and ground fighting, incorporating techniques from various combat sports from around the world. The first documented use of the term mixed martial arts was in a review of UFC 1 by television critic Howard Rosenberg in 1993. During the early 20th century, various interstylistic contests took place throughout Japan and in the countries of the Four Asian Tigers.
Historical European martial artsHistorical European martial arts (HEMA) are martial arts of European origin, particularly using arts formerly practised, but having since died out or evolved into very different forms. While there is limited surviving documentation of the martial arts of classical antiquity (such as Greek wrestling or gladiatorial combat), surviving dedicated technical treatises or martial arts manuals date to the Late Middle Ages and the early modern period. For this reason, the focus of HEMA is de facto on the period of the half-millennium of ca.
Styles of Chinese martial artsThere are hundreds of different styles of Chinese martial arts, each with their own sets of techniques and ideas. The various movements in kung fu, most of which are imitations of the fighting styles of animals, are initiated from one to five basic foot positions: normal upright posture and the four stances called dragon, frog, horse riding, and snake. The concept of martial arts styles appeared from around the Ming dynasty (13681644). Before the Ming period, martial skills were commonly differentiated mainly by their lineage.
Embodied cognitionEmbodied cognition is the theory that many features of cognition, whether human or otherwise, are shaped by aspects of an organism's entire body. The cognitive features include high-level mental constructs (such as concepts and categories) and performance on various cognitive tasks (such as reasoning or judgment). The bodily aspects involve the motor system, the perceptual system, the bodily interactions with the environment (situatedness), and the assumptions about the world built the functional structure of organism's brain and body.
Computational scienceComputational science, also known as scientific computing, technical computing or scientific computation (SC), is a division of science that uses advanced computing capabilities to understand and solve complex physical problems. This includes Algorithms (numerical and non-numerical): mathematical models, computational models, and computer simulations developed to solve sciences (e.
Computational physicsComputational physics is the study and implementation of numerical analysis to solve problems in physics. Historically, computational physics was the first application of modern computers in science, and is now a subset of computational science. It is sometimes regarded as a subdiscipline (or offshoot) of theoretical physics, but others consider it an intermediate branch between theoretical and experimental physics - an area of study which supplements both theory and experiment.
Computational chemistryComputational chemistry is a branch of chemistry that uses computer simulation to assist in solving chemical problems. It uses methods of theoretical chemistry, incorporated into computer programs, to calculate the structures and properties of molecules, groups of molecules, and solids. It is essential because, apart from relatively recent results concerning the hydrogen molecular ion (dihydrogen cation, see references therein for more details), the quantum many-body problem cannot be solved analytically, much less in closed form.
Okinawan martial artsOkinawan martial arts refers to the martial arts, such as karate, tegumi and Okinawan kobudō, which originated among the indigenous people of Okinawa Island. Due to its central location, Okinawa was influenced by various cultures with a long history of trade and cultural exchange, including Japan, China and Southeast Asia, that greatly influenced the development of martial arts on Okinawa. In 1429, the three kingdoms on Okinawa unified to form the Kingdom of Ryukyu.
Usability testingUsability testing is a technique used in user-centered interaction design to evaluate a product by testing it on users. This can be seen as an irreplaceable usability practice, since it gives direct input on how real users use the system. It is more concerned with the design intuitiveness of the product and tested with users who have no prior exposure to it. Such testing is paramount to the success of an end product as a fully functioning application that creates confusion amongst its users will not last for long.
Computational economicsComputational Economics is an interdisciplinary research discipline that involves computer science, economics, and management science. This subject encompasses computational modeling of economic systems. Some of these areas are unique, while others established areas of economics by allowing robust data analytics and solutions of problems that would be arduous to research without computers and associated numerical methods.
Embodied agentIn artificial intelligence, an embodied agent, also sometimes referred to as an interface agent, is an intelligent agent that interacts with the environment through a physical body within that environment. Agents that are represented graphically with a body, for example a human or a cartoon animal, are also called embodied agents, although they have only virtual, not physical, embodiment. A branch of artificial intelligence focuses on empowering such agents to interact autonomously with human beings and the environment.
Computational statisticsComputational statistics, or statistical computing, is the bond between statistics and computer science. It means statistical methods that are enabled by using computational methods. It is the area of computational science (or scientific computing) specific to the mathematical science of statistics. This area is also developing rapidly, leading to calls that a broader concept of computing should be taught as part of general statistical education.
Computational mathematicsComputational mathematics is an area of mathematics devoted to the interaction between mathematics and computer computation. A large part of computational mathematics consists roughly of using mathematics for allowing and improving computer computation in areas of science and engineering where mathematics are useful. This involves in particular algorithm design, computational complexity, numerical methods and computer algebra. Computational mathematics refers also to the use of computers for mathematics itself.
User experience designUser experience design (UX design, UXD, UED, or XD) is the process of defining the experience a user would go through when interacting with a company, its services, and its products. Design decisions in UX design are often driven by research, data analysis, and test results rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance.
Tacit knowledgeTacit knowledge or implicit knowledge—as opposed to formal, codified or explicit knowledge—is knowledge that is difficult to express or extract; therefore it is more difficult to transfer to others by means of writing it down or verbalizing it. This can include motor skills, personal wisdom, experience, insight, and intuition. For example, knowing that London is in the United Kingdom is a piece of explicit knowledge; it can be written down, transmitted, and understood by a recipient.
Molecular dynamicsMolecular dynamics (MD) is a computer simulation method for analyzing the physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a fixed period of time, giving a view of the dynamic "evolution" of the system. In the most common version, the trajectories of atoms and molecules are determined by numerically solving Newton's equations of motion for a system of interacting particles, where forces between the particles and their potential energies are often calculated using interatomic potentials or molecular mechanical force fields.
