irratsionaalsete

Irratsionaalsete, a term derived from the Latin "irrationalis," refers to something lacking reason, sense, or logic. In mathematics, it specifically denotes numbers that cannot be expressed as a simple fraction p/q, where p and q are integers and q is not zero. These numbers have decimal representations that are non-terminating and non-repeating. Famous examples of irrational numbers include pi (π), the ratio of a circle's circumference to its diameter, and the square root of 2 (√2), the length of the diagonal of a unit square. The set of irrational numbers, denoted by the symbol I, is a subset of the real numbers.

Beyond mathematics, the concept of irrationality can extend to human behavior, ideas, or arguments that appear contradictory, inconsistent, or defy rational explanation. This can manifest in decision-making processes that seem to disregard evidence or logical consequences, or in belief systems that are not grounded in empirical observation or deductive reasoning. The assessment of something as irrational often depends on the context and the established norms or systems of logic being applied. It implies a deviation from what is considered reasonable or justifiable within a given framework.
