Nanotechnology, which is sometimes shortened to "Nanotech", refers to a field whose theme is the control of matter on an atomic and molecular scale. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size.
A plasma display panel (PDP) is a type of flat panel display common to large TV displays (37in. [940mm]). Many tiny cells between two panels of glass hold an inert mixture of noble gases. The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light. Plasma displays should not be confused with LCDs, another lightweight flatscreen display using different technology |

Jean Baudrillard, notorious French sociologist, cultural critic, and theorist of postmodernity, was born in 1929 in the northern town of Reims. Son of civil servants and grandson of peasant farmers, Baudrillard was the first in his family to attend university, is an ex- university sociology teacher, and a leading intellectual figure of his time. His early life is influenced by the Algerian war in the 1950s and 60s. He taught German in a Lycée before completing his doctoral thesis in sociology under the tuition of Henri Lefebvre. He then became an Assistant in September 1966 at Nanterre University of Paris X. He was associated with Roland Barthes, to whose semiotic analysis of culture his first book, The Object System (1968) is clearly indebted. He was also influenced by Marshall McLuhan who demonstrated the importance of the mass media in any sociological overview. Influenced by the student revolt at Nanterre University in 1968, he cooperated with a typical journal of the time, Utopie, evidently influenced by anarcho-situationism, structural Marxism and media theory, in which he published a number of theoretical articles on the ambience of capitalist affluence, and the critique of technology. He became Mâitre-assistant at the University in 1970, and left the school in 1987.

SIMULACRA AND SIMULATIONS
|
The simulacrum is never that which conceals the truth — it is the truth which conceals that there is none.
The simulacrum is true.
Ecclesiastes
If we were able to take as the finest allegory of simulation the Borges tale where the cartographers of the Empire draw up a map so detailed that it ends up exactly covering the territory (but where, with the decline of the Empire this map becomes frayed and finally ruined, a few shreds still discernible in the deserts — the metaphysical beauty of this ruined abstraction, bearing witness to an imperial pride and rotting like a carcass, returning to the substance of the soil, rather as an aging double ends up being confused with the real thing), this fable would then have come full circle for us, and now has nothing but the discrete charm of second-order simulacra.l
Abstraction today is no longer that of the map, the double, the mirror or the concept. Simulation is no longer that of a territory, a referential being or a substance. It is the generation by models of a real without origin or reality: a hyperreal. The territory no longer precedes the map, nor survives it. Henceforth, it is the map that precedes the territory — precession of simulacra — it is the map that engenders the territory and if we were to revive the fable today, it would be the territory whose shreds are slowly rotting across the map. It is the real, and not the map, whose vestiges subsist here and there, in the deserts which are no longer those of the Empire, but our own. The desert of the real itself.

HIGH-DEFINITION VIDEO TECHNOLOGY
|
High-definition (HD) video generally refers to any video system of higher
resolution than standard-definition (SD) video, most commonly at display
resolutions of 1280×720 (720p) or 1920×1080 (1080i or 1080p). This article
discusses the general concepts of high-definition video, as opposed to its specific
applications in television broadcast (HDTV), video recording formats (HDCAM, HDCAM-SR,
DVCPRO HD, D5 HD, XDCAM HD, HDV and AVCHD), the optical disc delivery system Blu-ray Disc and the video tape format D-VHS.

A digital system uses discrete (discontinuous) values, usually but not always
symbolized numerically (hence called "digital") to represent information for input, processing,
transmission, storage, etc. By contrast, non-digital (or analog) systems use a continuous range
of values to represent information. Although digital representations are discrete, the information
represented can be either discrete, such as numbers, letters or icons, or continuous, such as sounds,
images, and other measurements of continuous systems.

Blu-ray Disc (also known as Blu-ray or BD) is an optical
disc storage medium. Its main uses are high-definition video
and data storage. The disc has the same physical dimensions as
standard DVDs and CDs.The name Blu-ray Disc is derived from the blue
laser (violet-colored) used to read and write this type of disc. Because
of the wavelength (405 nanometres), substantially more data can be stored
on a Blu-ray Disc than on the DVD format, which uses a red (650nm) laser.
A two-layer Blu-ray Disc can store 50 gigabytes, almost six times the capacity
of a two-layer DVD, or ten and a half times that of a single-layer DVD.

Digital radio describes radio technologies which carry information as a
digital signal, by means of a digital modulation method. The most common meaning is digital
audio broadcasting technologies, but the topic may also cover TV broadcasting as well as
many two-way digital wireless communication technologies. The acronym DAB (Digital Audio
Broadcasting) is synonymous with the Eureka 147 standard.
