  Eccentricity (behavior)
  In popular usage, eccentricity refers to 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 (mathematics)
  In mathematics, the eccentricity, denoted e or \varepsilon, is a parameter associated with every conic section. It can be thought of as a measure of how much the conic section deviates from being circular.In particular,...

• Eccentricity vector
  Eccentricity vector
  In astrodynamics, the eccentricity vector of a Kepler orbit is the vector pointing towards the periapsis having a magnitude equal to the orbit's scalar eccentricity. The magnitude is unitless. For Kepler orbits the eccentricity vector is a constant of motion...
  
  
• Horizontal eccentricity
  Horizontal eccentricity
  Horizontal Eccentricity refers to the horizontal axis, measured in degrees, along the visual field. The blind spot extends from an eccentricity d1 to eccentricity d2 in temporal direction from the fovea. The size of the blind spot can be calculated as ArcTan - ArcTan .-External links:*...

• Orbital eccentricity
  Orbital eccentricity
  The orbital eccentricity of an astronomical body is the amount by which its orbit deviates from a perfect circle, where 0 is perfectly circular, and 1.0 is a parabola, and no longer a closed orbit...

  Eccentric anomaly
  In celestial mechanics, the eccentric anomaly is an angular parameter that defines the position of a body that is moving along an elliptic Kepler orbit.For the point P orbiting around an ellipse, the eccentric anomaly is the angle E in the figure...

  Eccentric Training
  Eccentric training is the lowering phase of an exercise. For example, in a biceps curl the action of lowering the dumbbell back down from the lift is the eccentric phase of that exercise — as long as the dumbbell is lowered slowly rather than letting it drop....
