What is The Awful Green Things from Outer Space?

In algebraic geometry, the Zariski tangent space is a construction that defines a tangent space at a point P on an algebraic variety V. It does not use differential calculus,...

In mathematics, a space form is a complete Riemannian manifold M of constant sectional curvature K. The three most fundamental examples are Euclidean n-space, the n-dimensional sphere, and hyperbolic space,...

In mathematics, algebraic spaces form a generalization of the schemes of algebraic geometry, introduced by Michael Artin for use in deformation theory. Intuitively, schemes are given by gluing together affine...

Inflatable space structures are structures which use pressurized air to maintain shape and rigidity. Notable examples of terrestrial inflatable structures include inflatable boats, and some military tents. Inflatable structures are...

PCI configuration space is the underlying way that the Conventional PCI, PCI-X and PCI Express perform auto configuration of the cards inserted into their bus.

In topology and related branches of mathematics, a totally disconnected space is a topological space that is maximally disconnected, in the sense that it has no non-trivial connected subsets. In...

Jianguomen Outer Street, also transliterated as Jianguomen Wai Avenue is a major street in urban Beijing. It forms part of the extended Chang'an Avenue. It runs from Jianguomen Bridge in...

The Kansas City Outer Belt and Electric Railroad was, despite its name, neither an electric railway nor any sort of interurban line. It was intended to be the final link...

The Range of the Awful Hand is a range of hills in the Galloway Hills range, part of the Southern Uplands of Scotland. The most westerly of three parallel ridges,...

Outer-grazer and inner-grazer are configurations of heliocentric orbit. All six diagrams show the Sun in the middle and a putative planet's orbital band. The latter is a ring whose inner...
