Joseph Binder (March 3, 1898 – June 26, 1972) was an Austrian graphic designer and painter. He is recognized as one of the pioneers of the modern poster, noted for his refined, stylized images and high-impact colors. Some of his best known works include posters for the 1939 New York World’s Fair, the U.S. Army Air Corps and the American Red ...
Pee-Chee folder. The Pee-Chee All Season Portfolio is an American stationery item that achieved popularity in the second half of the 20th century. It is commonly used by students for storing school sheets. The folder, which was originally produced solely in a peach-yellow tone, was first manufactured in 1943 by the Western Tablet and Stationery ...
In algebraic geometry. In algebraic geometry, the term branched covering is used to describe morphisms from an algebraic variety to another one , the two dimensions being the same, and the typical fibre of being of dimension 0. In that case, there will be an open set of (for the Zariski topology) that is dense in , such that the restriction of ...
In short, is a box that contains safety matches made of wooden sticks or cardboard stripes. It commonly has a coarse striking surface on one edge for lighting the matches contained inside. Matchboxes generally measure 5 x 3.5 x 1.5 cm. For some applications matchbooks have replaced matchboxes. It is generally used to carry matches in the pocket ...
In classical algebraic geometry, cyclic covers are a tool used to create new objects from existing ones through, for example, a field extension by a root element. [4] The powers of the root element form a cyclic group and provide the basis for a cyclic cover. A line bundle over a complex projective variety with torsion index may induce a cyclic ...
In topology, a covering or covering projection is a map between topological spaces that, intuitively, locally acts like a projection of multiple copies of a space onto itself. In particular, coverings are special types of local homeomorphisms. If is a covering, is said to be a covering space or cover of , and is said to be the base of the ...
In materials science, a polymer matrix composite ( PMC) is a composite material composed of a variety of short or continuous fibers bound together by a matrix of organic polymers. PMCs are designed to transfer loads between fibers of a matrix. Some of the advantages with PMCs include their light weight, high resistance to abrasion and corrosion ...
Geometry (from Ancient Greek γεωμετρία (geōmetría) 'land measurement'; from γῆ (gê) 'earth, land' and μέτρον (métron) 'a measure') [ 1] is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. [ 2] Geometry is, along with arithmetic, one of the ...
