Order Theory

Order theory is a branch of mathematics which investigates our intuitive notion of order using binary relations. It provides a formal framework for describing statements such as "this is less than that" or "this precedes that". This article introduces the field and provides basic definitions. A list of order-theoretic terms can be found in the order theory glossary.

Famous quotes containing the words order and/or theory:

    Where did we ever get the crazy idea that in order to make children do better, first we have to make them feel worse? Think of the last time you felt humiliated or treated unfairly. Did you feel like cooperating or doing better?
    Jane Nelson (20th century)

    ... the first reason for psychology’s failure to understand what people are and how they act, is that clinicians and psychiatrists, who are generally the theoreticians on these matters, have essentially made up myths without any evidence to support them; the second reason for psychology’s failure is that personality theory has looked for inner traits when it should have been looking for social context.
    Naomi Weisstein (b. 1939)
