Lux

The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watts per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human visual brightness perception. In English, "lux" is used in both singular and plural.

Explanation

Illuminance

Illuminance is a measure of how much luminous flux is spread over a given area. One can think of luminous flux (measured in lumens) as a measure of the total "amount" of visible light present, and the illuminance as a measure of the intensity of illumination on a surface. A given amount of light will illuminate a surface more dimly if it is spread over a larger area, so illuminance (lux) is inversely proportional to area when the luminous flux (lumens) is held constant.

Nyx

Nyx (English /ˈnɪks/;Ancient Greek: Νύξ, "Night";Latin: Nox) is the Greek goddess (or personification) of the night. A shadowy figure, Nyx stood at or near the beginning of creation, and mothered other personified deities such as Hypnos (Sleep) and Thanatos (Death), with Erebus (Darkness). Her appearances are sparse in surviving mythology, but reveal her as a figure of such exceptional power and beauty, that she is feared by Zeus himself.

Mythology and literature

Hesiod

In Hesiod's Theogony, Nyx is born of Chaos. With Erebus (Darkness), Nyx gives birth to Aether (Brightness) and Hemera (Day). Later, on her own, Nyx gives birth to Moros (Doom, Destiny), Ker (Destruction, Death), Thanatos (Death), Hypnos (Sleep), the Oneiroi (Dreams), Momus (Blame), Oizys (Pain, Distress), the Hesperides, the Moirai (Fates), the Keres, Nemesis (Indignation, Retribution), Apate (Deceit), Philotes (Friendship), Geras (Old Age), and Eris (Strife).

In his description of Tartarus, Hesiod locates there the home of Nyx, and the homes of her children Hypnos and Thanatos. Hesiod says further that Nyx's daughter Hemera (Day) left Tartarus just as Nyx (Night) entered it; continuing cyclicly, when Hemera returned, Nyx left. This mirrors the portrayal of Ratri (night) in the Rigveda, where she works in close cooperation but also tension with her sister Ushas (dawn).

AMD Phenom

Phenom /fᵻˈnɒm/ is the 64-bit AMD desktop processor line based on the K10 microarchitecture, in what AMD calls family 10h (10 hex, i.e. 16 in normal decimal numbers) processors, sometimes incorrectly called "K10h". Triple-core versions (codenamed Toliman) belong to the Phenom 8000 series and quad cores (codenamed Agena) to the AMD Phenom X4 9000 series. The first processor in the family was released in 2007.

Background

AMD considers the quad core Phenoms to be the first "true" quad core design, as these processors are a monolithic multi-core design (all cores on the same silicon die), unlike Intel's Core 2 Quad series which are a multi-chip module (MCM) design. The processors are on the Socket AM2+ platform.

Before Phenom's original release a flaw was discovered in the translation lookaside buffer (TLB) that could cause a system lock-up in rare circumstances; Phenom processors up to and including stepping "B2" and "BA" are affected by this bug. BIOS and software workarounds disable the TLB, and typically incur a performance penalty of at least 10%. This penalty was not accounted for in pre-release previews of Phenom, hence the performance of early Phenoms delivered to customers is expected to be less than the preview benchmarks. "B3" stepping Phenom processors were released March 27, 2008 without the TLB bug and with "xx50" model numbers.

Phenom (electron microscope)

Phenom is a small, table-top sized Scanning Electron Microscope (SEM) originally developed by Philips and FEI and further developed by Phenom-World. The microscope features a combination of optical and electron-optical images; the optical image enables a "Neverlost" function so operators may navigate to any point on the sample. Sample loading takes place in 4 seconds (to obtain the CMOS overview image) and only 30 seconds into the vacuum space via rapid transfer technology (no conventional load lock). The system user interface is controlled with a touch screen No SEM experience is required for users to achieve magnifications of up to 100,000 times with a resolution of down to 15 nm. An optional fully integrated X-ray analysis (EDS) system shows the user in just seconds what the sample is made of.
