Sirius

Sirius (/ˈsɪriəs/) is the brightest star (in fact, a star system) in the Earth's night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star. The name "Sirius" is derived from the Ancient Greek Σείριος (Seirios), meaning "glowing" or "scorcher". The system has the Bayer designation Alpha Canis Majoris (α CMa). What the naked eye perceives as a single star is actually a binary star system, consisting of a white main-sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, called Sirius B. The distance separating Sirius A from its companion varies between 8.2 and 31.5 AU.

Sirius appears bright because of both its intrinsic luminosity and its proximity to Earth. At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite, the Sirius system is one of Earth's near neighbors. Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years. After that time its distance will begin to increase and it will become fainter, but it will continue to be the brightest star in the Earth's sky for the next 210,000 years.

Sean Thackrey

Sean Thackrey is an American winemaker based in Marin County, California in the town of Bolinas. From a background as director of an art gallery, Thackrey has been described as an unconventional winemaker who has done pioneering work in promoting California Syrah.

Career

Thackrey studied art history at Reed College in Portland, OR, and the University of Vienna, but without graduating. He moved to Bolinas in 1964 and for a while worked as a book editor for the Sierra Club. In 1970, Thackrey, with Susan Thackrey and Cynthia Pritzker, opened the art gallery in San Francisco that became Thackrey & Robertson, by then in partnership with watercolorist Sally Robertson; the gallery remained operational until closed in 1995. Thackrey's particular expertise was in early photography, in exhibiting which the gallery was an internationally renowned pioneer.

After several years in Berkeley and San Francisco, Thackrey moved back to Bolinas in 1977. Following initial winemaking experiments with Cabernet Sauvignon grapes purchased from Fay Vineyard in Napa Valley, Thackrey became a bonded winemaker in 1981, as the Thackrey & Co. winery. Some early problems with lactobacillus led Thackrey to take extension courses at UC Davis, although he states he has little use for the scientific approach to winemaking.

Sirius Entertainment

Sirius Entertainment was an American comic book company which celebrated 15 years of publishing in 2009. Sirius has published popular titles such as Dawn, Poison Elves, Akiko, and Mark Smylie's epic fantasy Artesia series during its first years.

Axis (novel)

Axis is a science fiction novel by author Robert Charles Wilson, published in 2007. It is a direct sequel to Wilson's Hugo Award-winning Spin, published two years earlier. The novel was a finalist for the 2008 John W. Campbell Award.

Plot

Axis takes place on the new planet introduced at the end of Spin, a world the Hypotheticals engineered to support human life and connected to Earth by way of the Arch that towers hundreds of miles over the Indian Ocean. Humans are colonizing this new world — and, predictably, fiercely exploiting its resources, chiefly large deposits of oil in the western deserts of the continent of Equatoria.

Lise Adams is a young woman attempting to uncover the mystery of her father's disappearance ten years earlier. Turk Findley is an ex-sailor and sometimes-drifter. They come together when showers of cometary dust seed the planet with tiny remnant Hypothetical machines. Soon, this seemingly hospitable world becomes very alien, as the nature of time is once again twisted by entities unknown.

Cartesian coordinate system

A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually at ordered pair (0, 0). The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin.

One can use the same principle to specify the position of any point in three-dimensional space by three Cartesian coordinates, its signed distances to three mutually perpendicular planes (or, equivalently, by its perpendicular projection onto three mutually perpendicular lines). In general, n Cartesian coordinates (an element of real n-space) specify the point in an n-dimensional Euclidean space for any dimension n. These coordinates are equal, up to sign, to distances from the point to n mutually perpendicular hyperplanes.

Axis (album)

Axis is the second album released by Australian hip hop artist MC Pegz. It was released in 2005, 18 months after his debut album. This recording features appearances from other Australian MCs, including Hilltop Hoods, Hyjak N Torcha, and Debaser (Ethic and Sapient).
