A typical example of glide reflection in everyday life would be the track of footprints left in the sand by a person walking on a beach. Frieze group nr. 6 (glide-reflections, translations and rotations) is generated by a glide reflection and a rotation about a point on the line of reflection. It is isomorphic to a semi-direct product of Z and C 2.
A drawing of a butterfly with bilateral symmetry, with left and right sides as mirror images of each other.. In geometry, an object has symmetry if there is an operation or transformation (such as translation, scaling, rotation or reflection) that maps the figure/object onto itself (i.e., the object has an invariance under the transform). [1]
In psychoanalysis and other psychological theories, the unconscious mind (or the unconscious) is the part of the psyche that is not available to introspection. [1] Although these processes exist beneath the surface of conscious awareness, they are thought to exert an effect on conscious thought processes and behavior. [2]
The monkeys would respond, as if required to, to every stimulus (i.e. Hypermetamorphosis (psychology)). [ 29 ] The monkeys exhibited hypersexuality , demonstrating a sexual drive so strong that they would continuously stimulate their genitalia, copulate repeatedly and for long periods of time, and sometimes sustain small injuries in the process ...
The term hippocampus minor fell from use in anatomy textbooks and was officially removed in the Nomina Anatomica of 1895. [13] Today, the structure is just called the hippocampus, [10] with the term cornu Ammonis (that is, 'Ammon's horn') surviving in the names of the hippocampal subfields CA1–CA4. [14] [15] [16]
In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body. [1] For instance, in a vertebra, a process may serve for muscle attachment and leverage (as in the case of the transverse and spinous processes), or to fit (forming a synovial joint), with another vertebra (as in the case of the articular processes). [2]
In addition, with no peripheral visual cues allowing for an orientation relative to the earth there can be an illusion of the pilot being upright and the runway being tilted and sloping. As a result, the pilot initiates an aggressive descent and wrongly adjusts to an unsafe glide path below the desired three-degree glide path. [13]: 3
In another study [10] in the Journal of Family Psychology in 1998, researchers Cook and Douglas measured the validity of the looking glass self and symbolic interaction in the context of familial relationships. The study analyzed the accuracy of a college student's and an adolescent's perceptions of how they are perceived by their parents ...
