Exploration
Exploration refers to the historical practice of discovering remote lands. It is studied by geographers and historians. Two major eras of exploration occurred in human history: one of convergence, and one of divergence. The first, covering most of ''Human, Homo sapiens'' history, saw humans Recent African origin of modern humans, moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation. Early explorers settled in Europe and Asia; 14,000 years ago, some crossed the Settlement of the Americas, Ice Age land bridge from Siberia to Alaska, and moved southbound to settle in the Americas. For the most part, these cultures were ignorant of each other's existence. The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence. Early writings about exploration date back to the 4th millennium B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploratory Committee
In the election politics of the United States, an exploratory committee is an organization established to help determine whether a potential candidate should run for an elected office. They are most often cited in reference to candidates for president of the United States prior to campaign announcements and the primaries. Forming an exploratory committee for president almost always precedes an official candidacy, though some, such as Paul Wellstone in 2000 and Evan Bayh in 2008, have declined to formally run. Exploratory committees may be governed by law. For example, the District of Columbia legally defines ''Exploratory Committees'' as (in DC Official Code § 1-1101.01(6)(B)(vi)): Exploratory, draft or "testing the waters" committees are formed solely for the purpose of determining the feasibility of an individual’s candidacy for office. The activities of exploratory committees may include polling, travel, and telephone calls to determine whether the individual should bec ...

Exploratory Data Analysis
In statistics, exploratory data analysis (EDA) is an approach of analyzing data sets to summarize their main characteristics, often using statistical graphics and other data visualization methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling and thereby contrasts traditional hypothesis testing. Exploratory data analysis has been promoted by John Tukey since 1970 to encourage statisticians to explore the data, and possibly formulate hypotheses that could lead to new data collection and experiments. EDA is different from initial data analysis (IDA), which focuses more narrowly on checking assumptions required for model fitting and hypothesis testing, and handling missing values and making transformations of variables as needed. EDA encompasses IDA. Overview Tukey defined data analysis in 1961 as: "Procedures for analyzing data, techniques for interpreting the results of such procedures, ways of pla ...

Exploratory Engineering
Exploratory engineering is a term coined by K. Eric Drexler to describe the process of designing and analyzing detailed hypothetical models of systems that are not feasible with current technologies or methods, but do seem to be clearly within the bounds of what science considers to be possible within the narrowly defined scope of operation of the hypothetical system model. It usually results in paper or video prototypes, or (more likely nowadays) computer simulations that are as convincing as possible to those that know the relevant science, given the lack of experimental confirmation. By analogy with protoscience, it might be considered a form of protoengineering. Usage Due to the difficulty and necessity of anticipating results in such areas as genetic modification, climate change, molecular engineering, and megascale engineering, parallel fields such as bioethics, climate engineering and hypothetical molecular nanotechnology sometimes emerge to develop and examine hypotheses, ...

Exploratory (museum)
The Exploratory Hands-on Science Centre was a science museum in Bristol, England. The project was conceived in 1981 by Richard Gregory CBE, professor of neuropsychology at Bristol University, and was the first hands-on science museum in the United Kingdom. It was inspired by the creation of the Exploratorium in San Francisco which had opened some years earlier and which appointed him Osher Visiting Fellow in 1989. Prof. Gregory said: "As I see it 'hands-on science' is to stimulate interest in science and technology by presenting phenomena and experiments to show how things work at first hand.." History Initial funding for the idea came from the Nuffield Foundation and David Sainsbury through the Gatsby Charitable Foundation which he founded. From 1987 to 1989 the interactive science exhibits were temporarily housed in the city's Victoria Rooms. In 1989 they moved to permanent installation at Bristol Temple Meads railway station. There, the expanded exhibition occupied two floors o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploratory Research
Exploratory research is "the preliminary research to clarify the exact nature of the problem to be solved." It is used to ensure additional research is taken into consideration during an experiment as well as determining research priorities, collecting data and honing in on certain subjects which may be difficult to take note of without exploratory research. It can include techniques, such as: *secondary research - such as reviewing available literature and/or data * informal qualitative approaches, such as discussions with consumers, employees, management or competitors * formal qualitative research through in-depth interviews, focus groups, projective methods, case studies or pilot studies According to Stebbins (2001) "Social Science exploration is a broad-ranging, purposive, systematic prearranged undertaking designed to maximize the discovery of generalizations leading to description and understanding". His influential book argues that exploratory research should not use confi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploratory Search
Exploratory search is a specialization of information exploration which represents the activities carried out by searchers who are: * unfamiliar with the domain of their goal (i.e. need to learn about the topic in order to understand how to achieve their goal) or * unsure about the ways to achieve their goals (either the technology or the process) or * unsure about their goals in the first place. Exploratory search is distinguished from known-item search, for which the searcher has a particular target in mind. Consequently, exploratory search covers a broader class of activities than typical information retrieval, such as investigating, evaluating, comparing, and synthesizing, where new information is sought in a defined conceptual area; exploratory data analysis is another example of an information exploration activity. Typically, therefore, such users generally combine querying and browsing strategies to foster learning and investigation. History Exploratory search is a topic tha ...

Exploratory Surgery
Exploratory surgery is a diagnostic method used by doctors when trying to find a diagnosis for an ailment. With the invention of modern imaging techniques, exploratory surgery is becoming less common in humans. Due to the high cost and lower availability of advanced imaging for animals, exploratory surgery is more common in animals in modern practice. Exploratory surgery in humans Exploratory surgery is used to make a diagnosis when typical imaging techniques fail to find an accurate diagnosis. The use of new technologies such as MRIs have made exploratory surgeries less frequent. Many kinds of exploratory surgeries can now be performed using endoscopy which uses a camera and minimal incisions instead of more invasive techniques. The most common use of exploratory surgery in humans is in the abdomen, a laparotomy. If a camera is used, it's called a laparoscopy. A laparotomy can be used to diagnose cancer, endometriosis, gallstones, gastrointestinal perforation, appendicitis, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploratory Testing
Exploratory testing is an approach to software testing that is concisely described as simultaneous learning, test design and test execution. Cem Kaner, who coined the term in 1984, defines exploratory testing as "a style of software testing that emphasizes the personal freedom and responsibility of the individual tester to continually optimize the quality of his/her work by treating test-related learning, test design, test execution, and test result interpretation as mutually supportive activities that run in parallel throughout the project." While the software is being tested, the tester learns things that together with experience and creativity generates new good tests to run. Exploratory testing is often thought of as a black box testing technique. Instead, those who have studied it consider it a test ''approach'' that can be applied to any test technique, at any stage in the development process. The key is not the test technique nor the item being tested or reviewed; the key is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
