Abstract - Internal rotation is more common than is first apparent. Two apparently unrelated objects , the Sun and an egg, actually have something in common. Characteristics about the Sun's interior can be determined by investigating its solar oscillations. These oscillations are produced beneath the Sun's surface and hence reveal information about the regions of the Sun in which they originated. Through examining solar internal rotation , details about the thermodynamic structure and gas dynamics of the solar interior and their dependence upon radius, latitude, and time can be discovered .
Eggs also demonstrate a type of internal rotation.
The fluid interior of a raw egg is free to move about during rotation. In a hard boiled egg, however, the yolk and white are stabilized. Although present on different scales, rotation is the common factor among these objects. On a microscopic level, rotation is essentially internalized. Planets are analogous to this situation as their interior is often composed of different material and rotates as the body spins.
