Eccentricity (graph theory)
In the mathematical field of graph theory, the distance between two vertices in a graph is the number of edges in a shortest path (also called a graph geodesic) connecting them. This is also known as the geodesic distance or shortest-path dista ...

Eccentricity (mathematics)
In mathematics, the eccentricity of a conic section is a non-negative real number that uniquely characterizes its shape.
More formally two conic sections are similar if and only if they have the same eccentricity.
One can think of the eccentri ...

Orbital eccentricity
In astrodynamics, the orbital eccentricity of an astronomical object is a dimensionless parameter that determines the amount by which its orbit around another body deviates from a perfect circle. A value of 0 is a circular orbit, values betwee ...

Eccentric anomaly, the angle between the direction of periapsis and the current position of an object on its orbit
*
Eccentricity vector, in celestial mechanics, a dimensionless vector with direction pointing from apoapsis to periapsis
* Eccentric, a type of

Horizontal eccentricity Horizontal eccentricity refers to the horizontal axis, measured in degrees, along the visual field. The blind spot extends from an eccentricity ''d''1 to eccentricity ''d''2 in temporal direction from the fovea. The size of the blind spot can be c ...

Muscle contraction is the activation of tension-generating sites within muscle cells. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as w ...
