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.

Game theory is a mathematical theory of strategic interaction developed by economists, mathematicians and biologists.

The study of operations research (OR) is concerned with mathematical methods and tools for solving problems relating to the allocation of scarce resources subject to constraints. Frequently these problems have to do with determining the least cost or greatest profit possible for a cost or profit function subject to constraints such as capacities and required amounts over a very large number of variables. Important problems within this space include minimum cost routing problems, network maximum flow or minimum cost flow problems, and machine scheduling problems. The growing trends in OR increasingly utilize applications of more than one technique and involve individuals from other disciplines. Moreover, they involve a blend of "hard" and "soft" as well as a mixing of different "hard" or "soft" techniques with the increasing use of multiple methods within one piece of analysis. A creative thinking must look in detail at how those from disciplines outside of OR can come to work in the organizations on multi-disciplinary studies. Those who have come from such backgrounds, clearly share their perspectives and experiences. The field of OR is always changing. Its changes are driven by the technology it uses and that it extends, and the applications that it affects.

Bioinformatics is broadly defined as the use of computers to analyse biological information. The most common form of bioinformatics is studying the vast amounts of DNA and protein sequence that are now available. However, there are many other possible applications of computers in biology, such as simulating populations, analysing experimental gels and storing information about the phenotypes of mutant organisms.

Coding Theory is the mathematical study of error-detection and error-correction in communication systems.

This category is for any site related to actuarial science and the actuarial profession, members of whom are called actuaries. What is an actuary? Consider the following description from BeAnActuary.com: "Actuaries put a price tag on future risks. They have been called financial architects and social mathematicians because their unique combination of analytical and business skills is helping to solve a growing variety of financial and social problems. Actuaries make financial sense of the future. How? An actuary applies mathematical models to problems of insurance and finance. To be more specific, actuaries improve financial decision making by developing models to evaluate the current financial implications of uncertain future events. If you've never met an actuary, that's not unusual. The actuarial profession numbers only about 19,000 people in North America. But don't let that small number fool you. Actuaries put their special problem-solving skills to work in many different business situations, and their work has had an influence on people's lives for more than a century. Actuaries make a difference. Their calculations and projections are the backbone of the insurance and financial security industries. Actuarial work involves lots of math, but actuaries must also be up-to-date on business issues and trends, social science, law, and economics. In other words, actuaries have a well-rounded business approach to problem solving. And they must be good communicators to explain things to nonactuaries. Actuaries are key players on a company's management team. They are well paid, and they like what they do for a living."
