The 4D style, or cosmic comics and relativistic humor, is based on Einstein's theory of relativity which I came up with 20 years ago. 4D works use the idea of the fourth dimension, time, playing on such surrealistic and amazing subjects as motion relativity, space curvature and time dilation. Javad Alizadeh
The horizon seems quite close to you because the curvature is so much more pronounced than here on Earth. Neil Armstrong
Indeed, linear extrapolations make no large-scale sense in a universe that has spatial and temporal curvature. Peter J. Carroll
He was a tall man with an astonishing and somehow elegant curvature of the spine, formed by an enlarged lower abdomen, which he carried in a stately and contented way, as if it contained money and securities. John Cheever
Gleizes was only trying to reduce the curvature of natural volumes to adapt them more naturally and rigorously to the surface of the painting, a surface which he believed to be continuous with the wall and, for all practical purposes, with no curvature at all. Jean Metzinger
