1.1 Sets of Real Numbers and The Cartesian Coordinate
... above definition of C, we see that every real number is a complex number. In this sense, the sets N, W, Z, Q, R, and C are ‘nested’ like Matryoshka dolls. For the most part, this textbook focuses on sets whose elements come from the real numbers R. Recall that we may visualize R as a line. Segments ...

Chapter 5 Cardinality of sets
... P(X) defined by f (x) = {x} for each x ∈ X is 1-1, so (since replacing the target of this function by its range this function to its range gives a 1-1 correspondence between X and a subset of P(X)) the cardinality of P(X) is “at least as big” as the cardinality of X. Theorem 5.6.1 No set can be put ...

Infinity

Infinity (symbol: ∞) is an abstract concept describing something without any limit and is relevant in a number of fields, predominantly mathematics and physics.In mathematics, ""infinity"" is often treated as if it were a number (i.e., it counts or measures things: ""an infinite number of terms"") but it is not the same sort of number as natural or real numbers. In number systems incorporating infinitesimals, the reciprocal of an infinitesimal is an infinite number, i.e., a number greater than any real number; see 1/∞.Georg Cantor formalized many ideas related to infinity and infinite sets during the late 19th and early 20th centuries. In the theory he developed, there are infinite sets of different sizes (called cardinalities). For example, the set of integers is countably infinite, while the infinite set of real numbers is uncountable.
