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.
Artificial Intelligence is a field of science that has several goals. The first, often called "weak" AI, is the effort to design and implement computer systems that can perform tasks requiring intelligence when performed by humans. AI in computer games, knowledge based systems and such are typical examples of this branch. The second, less tangible branch, often called "strong" AI, is the research that ultimatly aims to build artificial systems that display real intelligence. It does this by trying to understand or model the nature of human intelligence. Both branches are multidisciplinary, in that they have close relations with the fields of computer science, philosophy, medicine, psychology, biology and linguistics.
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.

Known by other scientists as the "Dismal Science," this field makes a serious effort to study and describe:
The production, distribution, exchange, and consumption of wealth and the various related issues (problems) of labor, finance, taxation, currencies, the political arena as it relates to the above areas of goods and services.
Although interest in economic theories dates to the origins of commerce itself, economics as a modern study independent of moral or political philosophy is attributed to the Scottish writer Adam Smith (1723-1790). The ideas put forth in his seminal work, Wealth of Nations, form the basis of "classical" economic theory and free-market capitalism.
In general, the concept of energy refers to the potential for causing changes. In physics, energy is the ability to do work and has many different forms (potential, kinetic, electromagnetic, etc.) No matter what its form, physical energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter.
Topics for this category include energy resources, energy utilization technologies, technology research and technical innovations, and analytical aspects of energy policy.

It is often an inexact science, especially when forecasting is involved, so that predictions often are stated as a percentage of probability. Listings here should concern the scientific practice of meteorology, information about weather events of historical interest, meteology as a hobby, and some instruments and products which either facilitate scientific meteorology or come from that background. Listings related to finding or reporting weather news should go to News: Weather.
Open to English-language sites relating to Linguistics, the study of human languages.

"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."

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.
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).

An accident reconstructionist is someone qualified to analyze the many different aspects of n accident and render an opinion on how and why the accident happened. The reconstructionist may also offer an opinion on how the accident may have been avoided. A reconstructionist will not, generally, determine a level of fault or guilt to one party over another. Every accident results from the interplay of a wide variety of factors. For example, in a traffic accident, a reconstructionist may have to assess the role of vehicle speed, time, distance, ambient lighting, seat belt use, air bags, component failure, brakes, human factors, alcohol as a factor, collision avoidance, crashworthiness and tire failures just to name a few possible factors. It is advisable to consult with an attorney if you have been involved in an accident that resulted in injuries.

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.

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 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 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).
