Geir Arne Olsen (1957 - 1990), better known under his pen-name Leonard Borgzinner, was a Norwegian essayist, self-taught political philosopher, science fiction author, illustrator and fanzine editor.
 Borgzinner is most noted for his many contributions to the alternative culture magazine "Gateavisa" and for his two books, a collection of science fiction and fantasy stories, "Universets varmedød og andre selvmord" (1981; "The Heat-Death of the Universe and other Suicides") and a collection of essays in political philosophy, "Anarki og adel: elementer til en kulturrevolusjon" (1998; "Anarchy and Nobility: Elements towards a Cultural Revolution").
 As an illustrator he was known for his often satirical drawings for fanzines and underground publications, including some comic strips.
 His fanzine production in the late 1970s, still partly under the name of Geir Arne Olsen, spanned both science fiction fandom and the punk music world, the former in the fanzines "TRALFA" and "The Borgzinner Medicine Show", and the latter most notably in the two published issues of "666", published in opposition to the Norwegian punk establishment.
 Influences on his work included Pre-Socratic philosophy, Marquis de Sade, anarchism, Friedrich Nietzsche, William S. Burroughs, new wave science fiction, Samuel R. Delany, Yukio Mishima and Michel Foucault.
"Aye, and Gomorrah..." is a science fiction short story by American writer Samuel R. Delany.
 It is the first short story Delany sold, and won the 1967 Nebula Award for best short story.
 Before it appeared in "Driftglass" and "Aye, and Gomorrah, and other stories", it first appeared as the final story in Harlan Ellison's seminal 1967 anthology, "Dangerous Visions".
 It was controversial because of its disturbing sexual subject matter, and has been called "one of the best stories by a gay man published in the 1960s."
Harlan Coben (born January 4, 1962) is an American writer of mystery novels and thrillers.
 The plots of his novels often involve the resurfacing of unresolved or misinterpreted events in the past, murders, or fatal accidents and have multiple twists.
 Among his novels are two series, each involving the same protagonist set in and around New York and New Jersey, and some characters appear in both.
Afrofuturism is a cultural aesthetic, philosophy of science, and philosophy of history that combines elements of science fiction, historical fiction, fantasy, Afrocentrism, and magic realism with non-Western cosmologies in order to critique not only the present-day dilemmas of black people, but also to revise, interrogate, and re-examine the historical events of the past.
 First coined by Mark Dery in 1993, and explored in the late 1990s through conversations led by scholar Alondra Nelson, Afrofuturism addresses themes and concerns of the African diaspora through a technoculture and science fiction lens, encompassing a range of media and artists with a shared interest in envisioning black futures that stem from Afrodiasporic experiences.
 Seminal Afrofuturistic works include the novels of Samuel R. Delany and Octavia Butler; the canvases of Jean-Michel Basquiat and Angelbert Metoyer, and the photography of Renée Cox; the explicitly extraterrestrial mythoi of Parliament-Funkadelic, the Jonzun Crew, Warp 9, Deltron 3030, and Sun Ra; and the Marvel Comics character Black Panther.
Readercon is an annual science fiction convention, held every July in the Boston, Massachusetts area, in Burlington, Massachusetts.
 It was founded by Bob Colby and statistician Eric Van in the mid-1980s with the goal of focusing almost exclusively on science fiction/fantasy/slipstream/speculative fiction in the written form (on the rare occasion that there is a discussion held about non-written science fiction, it will have a tongue-in-cheek title such as "Our biannual media panel").
 Past guests of honor have included authors such as Greer Gilman, Gene Wolfe, Octavia Butler, Samuel R. Delany, Karen Joy Fowler, Brian Aldiss, Nalo Hopkinson, Joe Haldeman, Caitlín R. Kiernan, Peter Straub, and China Miéville, and editors such as Ellen Datlow and David G. Hartwell.
 The convention also makes a point of honoring a deceased author as the Memorial Guest of Honor.
 In 2009, for instance, the guests of honor were the living writers Elizabeth Hand and Greer Gilman and the memorial guest of honor was Hope Mirrlees.
Stars in My Pocket Like Grains of Sand (1984) is a science fiction novel by Samuel R. Delany.
 It was part of a planned duology ("diptych", in Delany's description) whose second half, "The Splendor and Misery of Bodies, of Cities", remains unfinished.
The Motion of Light in Water: Sex and Science Fiction Writing in the East Village is an autobiography by science fiction author Samuel R. Delany in which he recounts his experiences as growing up a gay African American, as well as some of his time in an interracial and open marriage with Marilyn Hacker.
 It describes encounters with Albert Einstein, Bob Dylan, and Stokely Carmichael, a dinner with W. H. Auden, and a phone call to James Baldwin.
 Hazel Carby called it one of two contemporary autobiographies that are "absolutely central to any consideration of black manhood" (the other being that of Miles Davis).
 Among many cultural events of the decade that he witnessed, Delany recounts his attendance at the first New York City performance of artist Allan Kaprow's "18 Happenings in 6 Parts", the 1959 performance piece that, for many, marks the end of modernism and the beginning of postmodernism.
 In section 17.4 of the University of Minnesota Press edition, he describes the event and its venue, and speculates on its artistic significance.
 The introduction puts an emphasis on the idea of the unreliable narrator; Delany's accounts often contrast his life as it "felt" to ways in which it actually occurred.
 In the chapter, The Future Is in the Present of the book "Cruising Utopia" by José Esteban Munoz, Delany's The Motion of Light in the Water serves to explain how the future, as a formed of utopia, can be "glimpsed" in the present through what Delany employed as "the massed bodies" of sexual dissidence.
