In mathematical logic, Russell's paradox (also known as Russell's antinomy) is a set-theoretic paradox published by the British philosopher and mathematician, Bertrand Russell, in 1901.

Steady State theory → – In scientific terms, a scientific theory is an established explanation of an aspect of the natural world; this particular explanation was rejected, so it is not a scientific theory but a scientific model. Throughout this article, its name is inconsistently showed as "theory" and "model".
