The term Generation X has been used at various times throughout history to describe alienated youth. In the 1950s, Hungarian photographer Robert Capa used Generation X as the title for a photo-essay about young men and women growing up immediately following the Second World War. In 1976, English musician Billy Idol used the moniker as the name for a punk rock band.
An atlas is defined as a collection of various maps of the Earth or a specific region of the Earth such as the United States or Europe.
It is named for the Atlas of Greek mythology, because it supports the globe of the head. The atlas is the topmost vertebra and with the axis forms the joint connecting the skull and spine. The atlas and axis are specialized to allow a greater range of motion than normal vertebrae. They are responsible for the nodding and rotation movements of the head. The atlanto-occipital joint allows the head to nod up and down on the vertebral column. The dens acts as a pivot that allows the atlas and attached head to rotate on the axis, side to side. The atlas's chief peculiarity is that it has no body.
