... sentence φ in the language, either φ is a formal theorem (i.e. there exists a proof of φ from the axioms), or else φ can be contradicted, i.e. there exists a proof of ¬φ from the axioms. 1 If we have in mind a particular model M of the axioms, consistency is automatically true. Conversely, Gödels c ...

... any given angle θ ? III. (Squaring the Circle) Is it possible using only straightedge and compass to construct a square whose area is precisely the area of a given circle? To answer these questions we must translate the construction of lengths by compass and straightedge into algebraic terms. Let 1 ...

... of the same physical sort as A , such as a rotation through the same angle, but performed about some different (but physically equivalent) axis which is related to the axis of A by the group operation X-'. This is the significance of operators being in the same class. As a concrete example, consider ...
