The front dial also includes a second mechanism with a spherical model of the Moon that displays the lunar phase.

A great circle track is the shortest distance between two points on the surface of a planetary body, assuming a perfect spherical model.

Eventually, cylindrical chemical bomblets, such as the M125, were supplanted by spherical models because they could obtain a greater coverage area.

The method is a generalization of Eddington's formula for constructing isotropic spherical models.

For the critical temperature occurs at absolute zero, resulting in no phase transition for the spherical model.

The critical behaviour of the spherical model was derived in the completely general circumstances that the dimension d may be a real non-integer dimension.

This article deals primarily with spherical and ellipsoidal models of the Earth.

It is also common to refer to any mean radius of a spherical model as "the radius of the earth".

The hyperspherical model is the generalization of the spherical model to higher dimensions.

We call this model the spherical model.
