Real Spaces: World Art History and the Rise of Western Modernism is a non-fiction book by art historian David Summers, who aims to reconcile Western art history to artistic cultural production around the world from all time periods.
Real space can mean: . In physics, space in the real world, as opposed to some mathematical space or fictional space (such as hyperspace). Three-dimensional Euclidean space ...
Most commonly, it is the three-dimensional Euclidean space, that is, the Euclidean space of dimension three, which models physical space. More general three-dimensional spaces are called 3-manifolds. The term may also refer colloquially to a subset of space, a three-dimensional region (or 3D domain), [1] a solid figure.
Cartesian coordinates identify points of the Euclidean plane with pairs of real numbers. In mathematics, the real coordinate space or real coordinate n-space, of dimension n, denoted R n or , is the set of all ordered n-tuples of real numbers, that is the set of all sequences of n real numbers, also known as coordinate vectors.

SEOUL (Reuters) -Samsung Electronics' preliminary fourth-quarter operating profit missed estimates by a large margin, with the South Korean tech giant hit hard by extra costs as it works towards ...
Although this simple model would work best above the equator, Paul Birch calculated that since the ring station can be used to accelerate the orbital ring eastwards as well as hold the tether, it is therefore possible to deliberately cause the orbital ring to precess around Earth instead of staying fixed in space while Earth rotates beneath it ...
