eccentricity

/ ĕk′sĕn-trĭsĭ-tē /

  1. A measure of the deviation of an elliptical path, especially an orbit, from a perfect circle. It is equal to the ratio of the distance between the foci of the ellipse to the length of the major axis of the ellipse (the distance between the two points farthest apart on the ellipse). Eccentricity ranges from zero (for a perfect circle) to values approaching 1 (highly elongated ellipses).
  2. The ratio of the distance of any point on a conic section from a focus to its distance from the corresponding directrix. This ratio is constant for any particular conic section.

Synonym Study

Eccentricity, peculiarity, quirk, idiosyncrasy all refer to some noticeable deviation in behavior, style, or manner from what is normal or expected. Eccentricity usually suggests a mildly amusing but harmless characteristic or style: a whimsical eccentricity in choice of clothing. Peculiarity is the most general of these words, referring to almost any perceptible oddity or departure from any norm: the peculiarity of his eyelashes, of the weather. Quirk often refers to a minor, unimportant kind of oddity: Her one quirk was a habit of speaking to strangers in elevators. Sometimes quirk has overtones of strangeness: sexual quirks. Idiosyncrasy refers to a variation in behavior or manner exclusive to or characteristic of a single individual: idiosyncrasies of style that irritated editors but often delighted readers.
