  Closeness (mathematics) - Wikipedia, the free encyclopedia
In topology and related areas in mathematics closeness is one of the basic concepts in a topological space.
The concept can be defined naturally in a metric space where a notion of distance between elements of the space is defined, but it can be generalized to topological spaces where we have no concrete way to measure distances.
To define a closeness relation between two sets the topological structure is too weak and we have to use a uniform structure.

 Neighbourhood (mathematics) - Wikipedia, the free encyclopedia
In topology and related areas of mathematics, a neighbourhood (or neighborhood) is one of the basic concepts in a topological space.
Intuitively speaking, a neighbourhood of a point is a set containing the point where you can "wiggle" or "move" the point a bit without leaving the set.
This concept is closely related to the concepts of open set and interior.

 Topology Summary
The mathematical definition of 'not tearing', again speaking loosely, is that points that are close to each other in the first space should still be close to each other when they are mapped to the second space.
It is hard to imagine a space that does not come with a natural definition of closeness, but when a space is defined in an abstract way, instead of by a concrete picture, there is not always one definition of closeness that is more natural than others.
However, Lacan's use of topology, like his use of algebra, does not meet the standards of rigour normally evinced by a mathematical discipline, and should be seen more as an analogy (the value of which is left to the reader to decide upon) than as a branch of applied mathematics.

Several surprising associations are observed relative to (1) the aromatic residues tyrosine and tryptophan, but not phenylalanine; (2) multiple histidine residues; (3) asymmetries of arginine versus lysine, aspartate versus glutamate, alanine versus glycine, and asparagine versus glutamine; (4) absence of correlations of alpha-carbon distances with side-chain distances.
In contrast, for the closeness ordering corresponding to the minimum side-chain dm-distance, glycine and alanine are among the least associated.
However, in the d1-distance alanine is significantly close to all hydrophobic residues with the exception of tryptophan.

One way to divide the mathematics literature is to decide which books and articles are designed to reveal the structure of mathematics itself, and which are intended to apply mathematics to closely allied areas.
Algebra is principally concerned with symmetry, patterns, discrete sets, and the rules for manipulating arithmetic operations; one might think of this as the outgrowth of arithmetic and algebra classes in primary and secondary school.
The second broad part of the mathematics literature includes those areas which could be considered either independent disciplines or central parts of mathematics, as well as those areas which clearly use mathematics but are interested in non-mathematical ideas too.

Students wishing to keep open the option of a major in mathematics typically begin with the study of calculus in their first year and normally complete the calculus sequence, MATH 222 (Foundations of Analysis) and either MATH 118 or MATH 106 by the end of the sopho-more year.

 Closeness To Mother Can Delay First Instance Of Sexual Intercourse Among Younger Teens
WASHINGTON, D.C., and MINNEAPOLIS--Teenagers are less likely to start having sex when their mothers are involved in their lives, have a close relationship with them, and stress the importance of education, according to new findings from the largest survey ever conducted with adolescents in the United States.
Most importantly, teens, and especially younger teens, who feel close to their mothers are less likely to start having sex.
The Add Health findings identified a number of factors that are associated with postponement of early sex: For younger teens and older teenage boys, a strong sense of connectedness with their mothers in which the teen feels close to mom and perceives that she is warm and caring makes a difference.

Mathematics anxiety is prevalent among the preservice teacher population (Hembree, 1990).
Moreover, mathematics instructors who teach primarily through lecture and rote memorization of algorithms often neglect to meet the learning styles of all students and, therefore, may unintentionally perpetuate mathematics anxiety (Hodges, 1983; Zaslavsky, 1994).
The learning styles of elementary preservice teachers were paired with their levels of mathematics anxiety to determine if there was a correlation between mathematics anxiety and learning styles.
