- Z. Eccentricity is a measure of how an orbit deviates from circular. A perfectly circular orbit has an eccentricity of zero; higher numbers indicate more elliptical orbits. Neptune, Venus, and Earth are the planets in our solar system with the least eccentric orbits.

- Eccentric comes to us through Middle English from the Medieval Latin word eccentricus, but it is ultimately derived from a combination of the Greek words ex, meaning out of, and kentron, meaning center.. The original meaning of eccentric in English was not having the same center (as in eccentric spheres). In this sense, it contrasts with concentric, meaning having a common center (as in concentric circles, one within another).

Grey Gardens: What We Can Learn From The Edies But in America, eccentricity has different connotations. If we happen to like a person who has eccentric tendencies, we say, Oh, that so-and-so is such a character.. Characters of this variety are treated with an air of tolerance - as in, every town or family has one.

Definitions &Translations Eccentricity is unusual or odd behavior on the part of an individual. This behavior would typically be perceived as unusual or unnecessary, without being demonstrably maladaptive. Eccentricity is contrasted with normal behavior, the nearly universal means by which individuals in society solve given problems and pursue certain priorities in everyday life. People who consistently display benignly eccentric behavior are labeled as eccentrics.

Eccentricity (mathematics) The eccentricity of an ellipse is, most simply, the ratio of the distance between the center of the ellipse and each focus to the length of the semimajor axis. The eccentricity is also the ratio of the semimajor axis a to the distance d from the center to the directrix: The eccentricity can be expressed in terms of the flattening g (defined as g = 1 – b / a for semimajor axis a and semiminor axis b):

eccentricity 4. a mathematical constant expressed as the ratio of the distance from a point on a conic to a focus and the distance from the point to the directrix. syn: eccentricity, peculiarity, quirk, idiosyncrasy all refer to some deviation in behavior, style, or manner from what is or expected. eccentricity usu. suggests a mildly amusing but harmless characteristic or style: a whimsical eccentricity of dress. peculiarity is the most general of these words, referring to almost any perceptible oddity or departure from any norm: a peculiarity of the language.

Eccentricity of an Orbit If the eccentricity of an ellipse is close to one (like 0.8 or 0.9), the ellipse is long and skinny. If the eccentricity is close to zero, the ellipse is more like a circle. The eccentricity of Earth's orbit is very small, so Earth's orbit is nearly circular.Earth's orbital eccentricity is less than 0.02. The orbit of Pluto is the most eccentric of any planet in our Solar System.f the eccentricity of an ellipse is close to one (like 0.8 or 0.9), the ellipse is long and skinny.

Why does eccentric training produce eccentric-specific strength gains? (strength is specific) Eccentric training is strength training using only the lowering phase of an exercise. It is most commonly used for preventing or rehabilitating muscle strain injuries or tendinopathies. From a strength and conditioning point of view, eccentric training is very interesting because the strength gains are eccentric-specific. This means that the strength gains after eccentric training are greater when measured in an eccentric test of strength, compared to in a concentric test of strength.
