 Axiomatic set theory - Wikipedia, the free encyclopedia
Initially controversial, set theory has come to play the role of a foundational theory in modern mathematics, in the sense of a theory invoked to justify assumptions made in mathematics concerning the existence of mathematical objects (such as numbers or functions) and their properties.
Set theory is a branch of mathematics created principally by the German mathematician Georg Cantor at the end of the 19th century.
The important idea of Cantor's, which got set theory going as a new field of study, was to define two sets A and B to have the same number of members (the same cardinality) when there is a way of pairing off members of A exhaustively with members of B.

 Pointed set - Wikipedia, the free encyclopedia
In mathematics, a pointed set is a set X with a distinguished basepoint x
Maps of pointed sets (based maps) are functions preserving basepoints, i.e.
Pointed sets may be regarded as a rather simple algebraic structure.

 Pointed space - Wikipedia, the free encyclopedia
In mathematics, a pointed space is a topological space X with a distinguished basepoint x
Maps of pointed spaces (based maps) are continuous maps preserving basepoints, i.e.
Another way to think about this category is as the comma category, ({•} ↓ Top) where {•} is any one point space and Top is the category of topological spaces.

 Relational database programming - Retrieving results
The current record in the result set is pointed to by a cursor, by moving the cursor a different record of the result set can be read.
The names of the columns in the result set can be retrieved by calling the method columns/2, a list is returned with the column names in it.
After a SQL statement was executed the cursor is placed in front of the first record, so by calling the method fetchNextRow/3 the cursor is moved to the first record and the values of the columns of the record are put into a list.

 Random House for High School Teachers | Catalog | The Country of the Pointed Firs and Other Stories by Sarah Orne Jewett
The story of an endearing, unlikely friendship set against the backdrop of a remote and beautiful Maine coastal town, The Country of the Pointed Firs is one of Sarah Orne Jewett's most loved works, and it quickly earned her a reputation as a talented writer upon its publication.
Ironically, from the book's publication onward, there has been a general assumption from critics and local St. George inhabitants alike, that the events in Pointed Firs actually happened to Jewett, right down to the rental of a schoolhouse in which it is said she tried to write.
But it is The Country of the Pointed Firs that to this day remains her greatest work.In 1901 Bowdoin College granted her an honorary doctorate in literature—she was the first woman to be so honored by this prominent Maine institution.
