Cantor set

In mathematics, the Cantor set is a set of points lying on a single line segment that has a number of remarkable and deep properties. It was discovered in 1874 by Henry John Stephen Smith and introduced by German mathematician Georg Cantor in 1883. Through consideration of this set and others helped lay the foundations of modern point-set topology. Although Cantor himself defined the set in a general, abstract way, the most common modern construction is the Cantor ternary set, built by removing the middle third of a line segment and repeating the process with the remaining shorter segments. Cantor himself mentioned the ternary construction only in passing, as an example of a more general idea, that of a perfect set, nowhere dense; the Cantor ternary set C is created by iteratively deleting the open middle third from a set of line segments. One starts by deleting the open middle third from the interval, leaving two line segments: ∪. Next, the open middle third of each of these remaining segments is deleted, leaving four line segments: ∪ ∪ ∪.

This process is continued ad infinitum, where the nth set is C n = C n − 1 3 ∪ for n ≥ 1, C 0 =. The Cantor ternary set contains all points in the interval that are not deleted at any step in this infinite process: C:= ⋂ n = 1 ∞ C n; the first six steps of this process are illustrated below. Using the idea of self-similar transformations, T L = x / 3, T R = / 3 and C n = T L ∪ T R, the explicit closed formulas for the Cantor set are C = ∖ ⋃ n = 0 ∞ ⋃ k = 0 3 n − 1, where every middle third is removed as the open interval from the closed interval = surrounding it, or C = ⋂ n = 1 ∞ ⋃ k = 0 3 n − 1 − 1 ( ∪ [ 3 k + 2


Samois was a lesbian-feminist BDSM organization based in San Francisco that existed from 1978 to 1983. It was the first lesbian BDSM group in the United States, it took its name from Samois-sur-Seine, the location of the fictional estate of Anne-Marie, a lesbian dominatrix character in Story of O, who pierces and brands O. The co-founders were writer Pat Califia, who identified as a lesbian at the time, Gayle Rubin, sixteen others; the roots of Samois were in a group called Cardea, a women's discussion group within the mixed-gender BDSM group called the Society of Janus. Cardea existed from 1977 to 1978 before discontinuing, but a core of lesbian members, including Califia and Rubin, were inspired to start Samois on June 13, 1978, as an lesbian BDSM group. Samois was rebuked by Women Against Violence in Pornography and Media, an early anti-pornography feminist group. WAVPM, like anti-pornography feminists, was strongly opposed to sadomasochism, seeing it as ritualized violence against women. Samois members felt that their way of practicing SM was compatible with feminism, held that the kind of feminist sexuality advocated by WAVPM was conservative and puritanical.

Samois confronted WAVPM with their position, the exchanges between the two groups were among the earliest battles of what became known as the Feminist Sex Wars, with Samois being among the earliest advocates of what came to be known as sex-positive feminism. The book Coming to Power, edited by members of the Samois group and published in 1981, was a founding work of the lesbian BDSM movement. Samois split up in 1983 amid personal infighting; the Outcasts lasted until 1997. A breakaway group, The Exiles, is still extant as of 2012 and carries on in the tradition of Samois and The Outcasts. In 1996, Pat Califia and Robin Sweeney published an anthology titled The Second Coming: A Leatherdyke Reader that contained historical information on The Outcasts, as well as other lesbian BDSM groups such as the Lesbian Sex Mafia and Briar Rose. In 2007 the National Leather Association International inaugurated awards for excellence in SM/fetish/leather writing; the categories include the Samois award for anthology.

In 2019 Samois was inducted into the Leather Hall of Fame. Rubin, Gayle. 2004. Samois. Leather Times 21:3–7. Available from: Samois. 1979.

Gray's Reef National Marine Sanctuary

Gray's Reef National Marine Sanctuary is one of the largest near shore live-bottom reefs in the southeastern United States. The sanctuary, designated in January 1981, is located 19 miles off Sapelo Island, is one of 14 marine sanctuaries and monuments that make up the U. S. National Marine Sanctuary System. Within the 22-square-mile sanctuary, there are sandy flat places; the reef's rocky sandstone outcrops, submerged beneath 60 to 70 feet of water, can be as tall as 2 to 3 m and are complex. These nooks and crannies provide plenty of places for invertebrates to latch on to and for fish to hide in. Together these animals form a dense tapestry of living creatures that in places hides the rock; that gives the habitat of Gray's Reef its common name — a "live bottom". Researchers from NOAA and the University of Georgia have used the site to study invertebrate and vertebrate paleontology as well as the effects of erosion. Although Gray's Reef is more than 19 miles beyond today's shoreline, 60 to 70 feet below the Atlantic Ocean, it was once dry land and part of the mainland as as 8,000 years ago.

Human occupation of this area dates back at least 13,250 years, coincides with one of the most dramatic periods of climate change in recent earth history, toward the end of the Ice Age, in the Late Pleistocene epoch. Sea levels were more than 200 feet lower than present levels, the Atlantic Ocean and Gulf of Mexico shorelines were 100 or more miles seaward of their present locations. A 2003 research project undertaken by University of Georgia researchers Ervan G, Sherri L. Littman, Megan Mitchell, looked at and reported on the Gray’s Reef fossils and artifacts, including artifacts from a period of occupation by Clovis culture and Paleoindian hunters dating back more than 10,000 years.
