Eccentricity

Eccentricity or eccentric may refer to:

  • Off-center
  • Eccentricity (behavior), odd behavior on the part of a person, as opposed to being "normal"
  • Eccentricity (graph theory) of a vertex in a graph
  • Eccentricity (mathematics), a parameter associated with every conic section
  • Eccentric (mechanism), a wheel that rotates on an axle that is displaced from the focus of the circle described by the wheel
  • Eccentricity vector
  • Horizontal eccentricity, in vision, degrees of visual angle from the center of the eye
  • Orbital eccentricity, in astrodynamics, calculated from orbital state vectors as an absolute value of eccentricity vector or using other methods based on orbital energy and angular momentum
  • Eccentric anomaly, the angle between the direction of periapsis and the current position of an object on its orbit

Famous quotes containing the word eccentricity:

    Eccentricity has always abounded when and where strength of character has abounded; and the amount of eccentricity in a society has generally been proportional to the amount of genius, mental vigour, and moral courage which it contained.
    John Stuart Mill (1806–1873)
