Oriental medicine includes various Eastern indigenous traditions: Chinese, Japanese, Thai, Korean, Polynesian, Vietnamese, Tibetan. Most have their bases in the philosophical foundation of the East: yin/yang theory.
Chiropractic is a method of treatment used by Chiropractors. Chiropractors specialise in the diagnosis and treatment of conditions which are due to mechanical dysfunction of the joints, particularly those of the spine. Chiropractors believe that many health problems are due to misalignment or subluxation of the joints in the spine and that this leads to problems with the nervous or neurological system of the body resulting in symptoms, pain, disease and ill health. By adjusting the joints of the spine or other joints of the body they help restore normal function. They treat people who have had accidents or sports injuries and those whose conditions may have been brought on by stress, lack of exercise, poor posture or illness. There are a number of different chiropractic methods of treatment. Some chiropractors also offer massage, advice on nutrition, diet, lifestyle, exercise and ergonomic advice.
Journals are mainly scientific medical peer reviewed academic publications.
...Informatics is an emerging discipline that has been defined as the study, invention, and implementation of structures and algorithms to improve communication, understanding and management of medical information. The end objective of biomedical informatics is the coalescing of data, knowledge, and the tools necessary to apply that data and knowledge in the decision-making process, at the time and place that a decision needs to be made. The focus on the structures and algorithms necessary to manipulate the information separates Biomedical Informatics from other medical disciplines where information content is the focus." Aamir M. Zakaria., MD "Medical Informatics Frequently Asked Questions"
Breathwork covers a range of therapeutic techniques designed to increase an individual's physical and mental well being. These techniques look to improve the awareness of breathing habits, and in some cases attempt to consciously change the way an individual takes in and expels air.
Nanotechnology: a general term covering nanoscale science and engineering. A more narrow definition is miniaturization engineering at the nanometer scale. Nano is a metric prefix meaning 'billionth', in this case, science, technology, and engineering at sizes measured in billionths of a meter, which is 1,000 times smaller than a micrometer. It is proposed to build electronic and mechanical devices which are made of very tiny parts (as are biotic systems), but which may have very large effects (as do biotic systems).
Cryptozoology is the study of hidden animals not formally recognized by science, but supported in some way by other forms of evidence such as eyewitness accounts or tracks. Examples include Bigfoot and lake monsters(such as the Loch Ness Monster).
Science is constantly reshaping itself through unexpected observations, new ideas, and revisions to old theories. While terms like "anomalies" or "alternative" may seem pejorative from an orthodox perspective, from an historical view these are the topics are the very life-blood of science. We must have heretics and revolutionaries challenging our beliefs, and advancing the state of the believable, otherwise science will stagnate into dogma.
Sociology encompasses and overlaps many fields involves in the study of social relationships and institutions, including organizational behavior, societal development and structure, and cross-cultural interaction. The term "sociology" as the scientific analysis of collective human behavior was coined in 1838 by Auguste Comte, but Max Weber and ?mile Durkheim are generally credited as the founders of the modern field. The listings in this category are self-consciously restricted to links offering academic content or information. This also means that commercial sites that don't provide academic content (e.g., book sellers as compared to academic journal sites maintained by publishers) will not be listed.

"Physics is the study and application of the fundamental laws of nature, including the laws of motion, gravity, electromagnetism, heat, and microscopic interactions. These laws govern the behavior of objects at all scales, from the smallest subatomic particles to the entire observable universe. In between, physicists study nuclear reactions, the interactions of atoms with light, properties of solids, chaotic dynamics of fluids, and the evolution of stars and galaxies, among many other applications."

If this doesn't tickle your fancy, there is always the quote from Rutherford: "In science, there is only physics; all the rest is stamp collecting."

Material science is concerned with understanding the properties of materials and how to create new ones.

Parallel computing is the science and art of programming computers that can do more than one operation at once, concurrently, during the same cycle, often via having more than one processor. Some parallel computers are just regular workstations that have more than one processor in them; others are giant single computers with many processors (these are generally referred to as supercomputers); and others are networks of individual computers. A network of computers configured to coordinate on computing problems is also called a cluster. Parallel computers can run some types of programs far faster than traditional single processor computers, often termed the von Neumann architecture. Programs that work on a single-processor computer don't automatically work on a parallel computer. Programmers must explicitly specify how to divide up the computing work between all available nodes. Information about writing programs especially for parallel computers is in Parallel_Computing/Programming. Many people have written libraries to help programmers write programs for parallel computers. Parallel computing is a very similar field to distributed computing. Both types of computing involve breaking apart a problem into many pieces and assigning each part to a computer, but the nodes of a distributed computer normally not communicate with each other while performing their computations, because they may be great distances apart. Sites related to distributed computing are in Computers/Computer_Science/Distributed_Computing. Information about supercomputers is located in Computers/Supercomputing.
Robotics is a term coined by Isaac Asimov to describe the field of science involving robots and related technologies. So what is a robot? The word comes from a 1923 Czech play called R.U.R. and described autonomous, humanoid robot servants. The original Czech word was robota, which means "servitude or forced labor". According to the Syrius Cybernetics Corporation of Douglas Adams' Hitchiker's Guide to the Galaxy, a robot is "your plastic pal who's fun to be with". A more conventional definition is, "A mechanical device that sometimes resembles a human and is capable of performing a variety of often complex human tasks". There are many other definitions, some a bit too narrow and some far too broad. We try to be as inclusive as possible, accepting sites about hobby robotics, industrial robotics, even those about the radio-controlled entertainment vehicles of "Robot Wars". Enjoy our selections. And if you don't agree with some of our choices, rest easy in the knowledge that someone else out there wouldn't agree with yours.
Computer programming is the art of writing software, instructions for computers to follow. At the base level, as understood by the computer, these instructions are written in machine code, or binary, pure numbers, quite difficult for humans to read and write. At a slightly higher level, these codes correspond to assembly language, short mnemonics for individual computer operations, that still correspond one to one with what the machine actually does. This is still unstructured, terse, and difficult to read or write in. Most programming is done in higher level, compiled languages, or even interpretedthat look like a cross between English and Algebra, and allow various abstractions depending on the language, such as encapsulation, function calls, data hiding, and more, to enable people reading and writing programs to deal with the vast quantity of information that the computer actually handles. Respectively, a compiler program translates these languages to machine code to be executed directly, or a separate interpreter program itself takes these statements and executes them as an intermediary.
The field of Home Automation is expanding rapidly as electronic technologies converge. The home network encompasses communications, entertainment, security, convenience and information systems. This category holds sites of broad scope on the topic.

Business consultants are individuals or firms with expertise in business procedures, practices and policy. Organizations of all types use consultants, and these consultants examine these organizations from a broad operational perspective applying a variety of skills to achieve a specific outcome, solution, or result. Through analysis and study, consultants provide problem resolution and prevention solutions related to business operations, infrastructure, and performance. Consultants have many roles, varying from a supportive one within an existing team, to providing temporary leadership over an identified problem area, to other independent activities conducted at the request of the organization. This category has been divided into three areas to reflect the many functions and roles within the business consulting profession. The top level is divided by some of the various specialty or focus areas typical to the business consulting industry (e.g., business formation, financial, management, manufacturing, outsourcing, etc.). The second level contains a variety of industry specific subcategories (e.g., construction, energy, engineering, science and industry, security, etc.). Within the lowest level is a list of closely related "See also" categories that may contain other types of consultants. Before you submit your site please take the time to look around the category to ensure that your site is appropriate to this category. Also, be sure to review the general guidelines for the Business categories. The editors reserve the right not to list your site, and to delete it after its addition. Multiple submissions may be considered when appropriate (for example, a site that contains valuable resources pertinent to multiple subcategories) but repeated submissions, especially to inappropriate categories, will not be tolerated. Please, submit only to those categories most appropriate to the content of your site.

NLP (Neuro-Linguistic Programming) is a powerful system for representing and influencing human behavior. It combines aspects of psychology, linguistics, and computer science. Its techniques have been applied to education, sales, therapy, and all sorts of other fields. Richard Bandler and John Grinder came up with the technology in the 1970's. Tony Robbins popularized it in the 1980's. In the 1990's, Bandler returned with DHE, or Design Human Engineering. Today, NLP's popularity is growing on the internet. These sites represent some of the most useful NLP resources on and off the web.

This category is for vendors and distributors of components used during the manufacture of electronic products.
This category is related to the technological and safety aspects of the production of useful energy released by the fission of heavy nucleus.
In the nuclear fission process, the nucleus of an atom splits into two smaller atoms (fission products). This occurs naturally in radioactive elements (radioactive decay), but it can be induced artificially by making fissionable atoms absorb free neutrons.
This causes the nucleus to become unstable and makes it split apart. The fission process yields two smaller atoms, energy and several fast neutrons. Therefore, under certain conditions, the reaction can become self sustaining. This is called a chain reaction, or nuclear criticality.
A nuclear reactor is an apparatus in which nuclear fission chain reactions are initiated, controlled, and sustained at a steady rate.
This category is about the technical aspects of spent nuclear fuel, management, reprocessing and disposal.
Spent nuclear fuel is used fuel from nuclear reactors at commercial power plants, research reactors, government facilities, or from the nuclear medicine.
These materials contain highly radioactive elements, such as cesium, strontium, technetium, and neptunium.
Some of these elements will remain radioactive for a few years, while others will be radioactive for millions of years.
Nuclear waste can be generally classified as either low level or high level radioactive waste. Low level nuclear waste usually includes material used to handle the radioactive parts of nuclear apparatus and waste from nuclear medicine. High level waste includes the fission products activated in nuclear reactors or in accelerators.
This category contains non-commercial scientific, educational, and governmental references to biomass and biofuel. Biomass is organic non-fossil material. It comprises the mass of all biological organisms, dead or alive, excluding biological mass that has been transformed by geological processes into substances such as coal or petroleum. Solid biomass comes in different forms including what comes directly from the “producers” (grass, trees, shrubs, crop husks, etc.) and that which comes as waste from the animals that consume the producers (droppings or dung from animals and waste from humans). Biofuel is any fuel that originates from biomass. The three classes of biomass used for combustion are solid (e.g. wood, dried plants and animal waste), liquid (e.g. ethanol, methanol and vegetable oil) and gaseous (e.g. bio-methane and hydrogen). Reference: Wikipedia: The Free Encyclopedia

Biodiversity is not easily defined. Try What is Biodiversity? and Defining The 'B' Word for approaches with differing emphases. Below is a definition adapted from the World Resources Institute, World Conservation Union, and United Nations Environment Programme in Global Biodiversity Strategy 1992.

"Biodiversity is the totality of genes, species, and ecosystems in a region... Biodiversity can be divided into three hierarchical categories -- genes, species, and ecosystems -- that describe quite different aspects of living systems and that scientists measure in different ways.

Genetic diversity refers to the variation of genes within species. This covers distinct populations of the same species (such as the thousands of traditional rice varieties in India) or genetic variation within a populations (high among Indian rhinos, and very low among cheetahs) ...

Species diversity refers to the variety of species within a region. Such diversity can be measured in many ways, and scientists have not settled on a single best method. The number of species in a region -- its species richness -- is one often- used measure, but a more precise measurement, taxonomic diversity, also considers the relationship of species to each other. For example, an island with two species of birds and one species of lizard has a greater taxonomic diversity than an island with three species of birds but no lizards ...

Ecosystem diversity is harder to measure than species or genetic diversity because the boundaries of communities -- associations of species -- and ecosystems are elusive. Nevertheless, as long as a consistent set of criteria is used to define communities and ecosystems, their numbers and distribution can be measured ..."

Resources related to biodiversity or conservation as an issue or a topic of debate belong primarily in the relevant subcategory of Society/Issues/Environment.

According to that quoted in http://www.bio.hw.ac.uk/edintox/enviro.htm (a cool site): Environmental toxicology and ecotoxicology are terms used to describe the scientific study of the adverse effects on living organisms that chemicals can have when released into the natural environment. There is a tendency to apply the term "environmental toxicology" only to the study of direct effects of environmental chemicals on human beings and the term "ecotoxicology" only to the study of the effects of chemicals on ecosystems and their nonhuman components.
Topics include climate change (or global warming), atmospheric C02, stratospheric ozone, desertification, and change indicators.
