Definitions for **"Symmetry"**

A due proportion of the several parts of a body to each other; adaptation of the form or dimensions of the several parts of a thing to each other; the union and conformity of the members of a work to the whole.

Similarity of form or structure with equal negative-positive sides from a neutral mid-point, like in all Trinitarian structures.

a property of figures such that for some given dividing line the parts on opposite sides of the line are the same size and shape and have the same relative position from the line

Measurement of the uniformity of the output waveform

A measure of the uniformity of the output waveform.

Symmetry is the ratio of the ON time to the OFF time of the output signal for one channel. This ratio is optimally 50-50.

a certain operation, namely a rigid transformation, that can be applied to that object such, that the result is that same object occupying exactly the same space as it occupied before the transformation took place

a set of transformations that transform one object onto another object

a transformation of an entity which preserves the properties of the entity

head and shoulders tops and bottoms often exhibit symmetry in their formation. If a pattern has two left shoulders, it may be expected to have to right shoulders. This is especially true of large capital stocks that form patterns over the course of a year. Further, in the case of long term patterns, one may expect symmetry in the period of formation of a right shoulder to an extent similar to that of the left shoulder. Thus if a left shoulder took six months to form, one might expect the right shoulder to take a similar period. However, there is no rule that symmetry shall apply. Symmetry is merely a presumption.

The shape or general outline of a person's body, as when seen in silhouette. If you have good sym-metry, you will have relatively wide shoulders, flaring lats, a small waist-hip structure, and generally small joints.

equality with respect to competitive ability as defined in a particular type of contest. An unlikely situation. In most of the models we consider, we assume symmetry as a simplification. If contestants are truly of equal ability, we assume that each has a 50% chance of winning the conflict with no resort to further escalation. In real situations, the closer the competitive abilities of two contestants, the more likely that a highly escalated conflict will occur. Symmetry can also refer to information availability or to a contestant's knowledge of the environment (including its opponent). So, for instance, when neither contestant in a pairwise contest knows before the contest starts the strategy the opponent will play or when both assess a resource at the same value, the contest is symmetrical with respect to these pieces of information. Clearly the presence or lack of informational symmetry could be an important factor in deciding a contest

The consistent representation of events in all strategies considered in the model. Events that occur in one strategy are represented in the same way in other strategies. The construction of symmetrical models is facilitated by using subtrees.

As defined by the AVSA for purposes of judging, the shape of an African Violet as determined by a number of factors according to the plant type under consideration. For standard African Violets, symmetry is achieved when the leaves form a rosette such that they are evenly distributed and form straight lines from the base of their stems to the tips of the leaves.

a common feature of melanoma, whereas most benign tumors tend to be symmetric in shape

A symmetry of a shape in the plane or space is a rigid motion that takes onto itself (T(S) = S). For example, reflection through a diagonal and a rotation through a right angle about the center are both symmetries of the square.

A way to organize text so it is visually pleasing and easy to read.

The mathematical division of spacial relationships that divide the flat visual space as percentages of the a sum total. 1/3, 1/4, ½, 3/4, etc.

The geometric state of being divisible into two or more parts, each of which is identical to the other.

A property exhibited by a relation if whenever R(a,b), then R(b,a). For example, identity is symmetric, since if a=b, then b=a.

an automorphism on the variables in a given theory, such that applying it does not change the theory

Invariance of equations of motion under changes in condition.

the property that makes a figure look balanced

balance among the parts of something

The physical and aesthetic balance between a woman's breasts.

Likeness in the form and size of floral organs of the same kind; regularity.

Equality in size and form between parts; correspondence or repetition of a pattern between or within structures within an organism. Table of Contents

Brokenness.

fundamental organizing principle in nature and art

Target Population

Equality in the number of parts of the successive circles in a flower.
