Calculus is a branch of mathematics concerned with two types of functions: derivatives and integrals.

The derivative calculates the rate of change of the function at a point on a curved line. This formula also works for a straight line, as well. A derivative of a function is written by adding a apostrophe like this: f'(x). One of the applications of derivatives is to determine velocity and acceleration of an object in motion.

Integrals measure the area under a curved line graph, such as a half circle. The integral symbol looks like a flattened S.

Derivatives and integrals are related in that they are inverse functions of each other. That means the operations will cancel each other out, such as taking the square root of a squared number will give you the original number.

Applications of integrals include calculating areas of plane regions or surfaces, as well as calculating volumes of solids.

Both derivatives and integrals are defined by using the concept of a limit. An example of a limit is where you have the equation 1/x. If you take x to be very large, then 1/x gets closer to 0.

Karst refers to any terrain where the topography has been formed chiefly by the dissolving of rock, primarily carbonates (such as limestone) and evaporites (such as salt). Landforms associated with karst include sinkholes, caves, sinking streams, springs, and solution valleys. Because of the unique geologic and hydrologic features associated with highly developed subterranean networks, the scope of problems related to the karst environment is large.
This category is for sites dealing with the science and technology of ceramics. Suppliers of products or services should submit their sites to an appropriate category in our Business section. Specific links to which can usually be found as an @linked sub category of this main category, or in the list of related categories.
Chaos theory, in mathematics and physics, deals with the behavior of certain nonlinear dynamical systems that (under certain conditions) exhibit the phenomenon known as chaos, most famously characterised by sensitivity to initial conditions. Systems that exhibit mathematical chaos are deterministic and thus orderly in some sense; this technical use of the word chaos is at odds with common parlance, which suggests complete disorder.
A fractal is a chaotic mathematic object which can be divided into parts, each of which is similar to the original object. Fractals are said to possess infinite detail, and are generally self-similar and independent of scale. In many cases a fractal can be generated by a repeating pattern, typically a recursive or iterative process. The term fractal was coined in 1975 by Benoît Mandelbrot, from the Latin fractus or "broken"/"fraction". Chaos theory, in mathematics and physics, deals with the behavior of certain nonlinear dynamical systems that (under certain conditions) exhibit the phenomenon known as chaos, most famously characterised by sensitivity to initial conditions.

Many specialties, professionals, support groups, patients and other communities in the health field have specific online communications.
Chemistry is typically defined as the science that studies the composition, structure, and transformation of matter. It has been called "the central science" because of the way it is related with all the other sciences. Chemistry bridges the gap between physics and biology; it is a "helper science" in almost many technical disciplines; and it occupies a prominent position in industry between the extraction of raw materials and the manufacture of finished products. Of course, it is chemists who call it this way; other scientists may have different perspectives. Chemistry is also distinguished from some other sciences because it creates its own object of study: chemists can imagine and create new compounds that have never existed in nature, so they are not constrained to what already exists, but only to what can be done.

Chemometrics is the application of statistical and mathematical tools for multivariate analysis of chemical measurements.
This category lists sites involved in exploring patterns of association, tracking properties and producing models for classification of data from chemical analysis.

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.
