Brian Randolph Greene (born February 9, 1963) is an American theoretical physicist, mathematician, and string theorist.
 He has been a professor at Columbia University since 1996 and chairman of the World Science Festival since co-founding it in 2008.
 Greene has worked on mirror symmetry, relating two different Calabi–Yau manifolds (concretely, relating the conifold to one of its orbifolds).
 He also described the flop transition, a mild form of topology change, showing that topology in string theory can change at the conifold point.
The New Zealand International Science Festival is a biennial science festival which takes place for six days and involves participation of international keynote speakers; NZISF-staff produce events, external event organisers, and a range of local and national sponsors and funders.
 Up to 40 individual volunteers help run 200 festival events and thousands of visitors from all over New Zealand participate in festival events.
 The festivals attract a significant amount of high-profile local, regional and national media coverage, in print, radio and TV.
 The festival was first held in 1997 and its aim is to celebrate, promote and raise awareness of science, technology and the environment.
 The festival encourages people and organisations (educational, research, business and community) to participate in the promotion of their work in science and its applications and contributions to society.
 They also aim to highlight the excellence of achievements in these fields by Dunedin, Otago and New Zealand scientists.
 Beside private sponsors, core contributors to the festival are the Dunedin City Council, The Community Trust of Otago and the University of Otago.
The Fabric of the Cosmos: Space, Time, and the Texture of Reality (2004) is the second book on theoretical physics, cosmology, and string theory written by Brian Greene, professor and co-director of Columbia's Institute for Strings, Cosmology, and Astroparticle Physics (ISCAP).
The North Carolina Science Festival (NCSF) is a multi-week event encompassing hundreds events across many disciplines throughout the state of North Carolina.
 The festival is organized by Morehead Planetarium and Science Center on the University of North Carolina at Chapel Hill campus with the goal of highlighting the educational, cultural and economic impact of science in the state.
 NCSF events include hands-on activities, talks, lab tours, exhibits and performances for all ages.
 The event has grown into the largest science festival in the world.
Jeffrey Vinokur (born August 24, 1990), who also goes by the stage name The Dancing Scientist, is an American science educator known for combining the hip hop dance genre of popping with live science demonstrations.
 He has performed his science and dance act on "The Today Show", "The View", "The Queen Latifah Show", "Rachael Ray", "America's Got Talent", and the Discovery Channel.
 He has also performed at the World Science Festival, Smithsonian Institution, and his online Popping videos have accumulated over 20 million hits.
The 2008 World Science Festival was a science festival held in New York City.
 The festival (May 28 – June 1, 2008) consisted mainly of panel discussions and on-stage conversations, accompanied by multimedia presentations.
 A youth and family program presented topics such as sports from a scientific perspective and included an extensive street fair.
 A cultural program led by actor and writer Alan Alda focused on art inspired by science.
 The festival also included a "World Science Summit", a meeting of high-level participants from the worlds of science, politics, administration, and business.
The Hugo Awards are a set of literary awards given annually for the best science fiction or fantasy works and achievements of the previous year.
 The awards are named after Hugo Gernsback, the founder of the pioneering science fiction magazine "Amazing Stories", and were officially named the Science Fiction Achievement Awards until 1992.
 Organized and overseen by the World Science Fiction Society, the awards are given each year at the annual World Science Fiction Convention as the central focus of the event.
 They were first given in 1953, at the 11th World Science Fiction Convention, and have been awarded every year since 1955.
 Over the years that the award has been given, the categories presented have changed; currently Hugo Awards are given in more than a dozen categories, and include both written and dramatic works of various types.
In materials science, texture is the distribution of crystallographic orientations of a polycrystalline sample (it is also part of the geological fabric).
 A sample in which these orientations are fully random is said to have no distinct texture.
 If the crystallographic orientations are not random, but have some preferred orientation, then the sample has a weak, moderate or strong texture.
 The degree is dependent on the percentage of crystals having the preferred orientation.
 Texture is seen in almost all engineered materials, and can have a great influence on materials properties.
 Also, geologic rocks show texture due to their thermo-mechanic history of formation processes.
The World Science Festival is an annual science festival produced by the World Science Foundation, a 501(c)(3) non-profit organization headquartered in New York City.
The 10th World Science Fiction Convention was held on Labor Day weekend from August 30 to September 1, 1952, at the Morrison Hotel in Chicago, Illinois.
 This Worldcon never chose an official name other than the title "10th World Science Fiction Convention," as both the convention's issued membership card and program book clearly stated.
 Only the first Worldcon in New York City (1939) and the 11th in Philadelphia, 1953, shared this lack of a formal convention name.
 The phrases "Tenth Anniversary World Science Fiction Convention" (TAWSFiC) and "Tenth Anniversary Science Fiction Convention" (TASFiC, likely a simple linotype error, as "World" is missing) were each used in some of this Worldcon's pre-convention materials; the phrase's acronyms "TAWSFiC" and "TASFiC" were never officially used in print or otherwise by the Chicago committee at that time.
 However, the 10th Worldcon "was" frequently referred to by its members by the unofficial name Chicon II, so dubbed after the previous Chicago Worldcon (Chicon) in 1940; this name proved so popular that the convention became known as Chicon II in science fiction fandom's lore and written histories.
