Album

Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, then from 1948 as vinyl LP records played at 33 ¹⁄₃ rpm. Vinyl LPs are still issued, though in the 21st century albums sales have mostly focused on compact disc (CD) and MP3 formats. The audio cassette was a format used in the late 1970s through to the 1990s alongside vinyl.

An album may be recorded in a recording studio (fixed or mobile), in a concert venue, at home, in the field, or a mix of places. Recording may take a few hours to several years to complete, usually in several takes with different parts recorded separately, and then brought or "mixed" together. Recordings that are done in one take without overdubbing are termed "live", even when done in a studio. Studios are built to absorb sound, eliminating reverberation, so as to assist in mixing different takes; other locations, such as concert venues and some "live rooms", allow for reverberation, which creates a "live" sound. The majority of studio recordings contain an abundance of editing, sound effects, voice adjustments, etc. With modern recording technology, musicians can be recorded in separate rooms or at separate times while listening to the other parts using headphones; with each part recorded as a separate track.

Arc (projective geometry)

A (simple) arc in finite projective geometry is a set of points which satisfies, in an intuitive way, a feature of curved figures in continuous geometries. Loosely speaking, they are sets of points that are far from "line-like" in a plane or far from "plane-like" in a three-dimensional space. In this finite setting it is typical to include the number of points in the set in the name, so these simple arcs are called k-arcs. An important generalization of the k-arc concept, also referred to as arcs in the literature, are the (k, d)-arcs.

k-arcs in a projective plane

In a finite projective plane π (not necessarily Desarguesian) a set A of k (k ≥ 3) points such that no three points of A are collinear (on a line) is called a k - arc. If the plane π has order q then k ≤ q + 2, however the maximum value of k can only be achieved if q is even. In a plane of order q, a (q + 1)-arc is called an oval and, if q is even, a (q + 2)-arc is called a hyperoval.

Every conic in the Desarguesian projective plane PG(2,q), i.e., the set of zeros of an irreducible homogeneous quadratic equation, is an oval. A celebrated result of Beniamino Segre states that when q is odd, every (q + 1)-arc in PG(2,q) is a conic. This is one of the pioneering results in finite geometry.

Arc (Provence)

The Arc is an 83-kilometre (52 mi) long river in the south of France. It arises at an elevation of 470 metres (1,540 ft), close to the village of Pourcieux. It then passes through Aix-en-Provence before flowing into the Étang de Berre, a lake to the west of Marseille.

Its drainage basin, with a surface area of 727 square kilometres (281 sq mi), is divided between two départments, Var and Bouches-du-Rhône. The risk of flood, always present in the basin, has been aggravated by urban development that has sometimes been lacking in foresight, with Aix-en-Provence particularly threatened.
