Shel Silverstein (1930 – 1999), was an American poet, musician, cartoonist, and author of children’s books. He styled himself as Uncle Shelby in his children’s books.
Silverstein grew up in Chicago: ‘When I was a kid—12 to 14, around there—I would much rather have been a good baseball player or a hit with the girls, but I couldn’t play ball. I couldn’t dance. Luckily, the girls didn’t want me. Not much I could do about that. So I started to draw and to write. I was also lucky that I didn’t have anybody to copy, be impressed by. I had developed my own style; I was creating before I knew there was a Thurber, a Benchley, a Price and a Steinberg. I never saw their work till I was around 30. By the time I got to where I was attracting girls, I was already into work, and it was more important to me. Not that I wouldn’t rather make love, but the work has become a habit.’

A Sound clash is a musical competition where crew members from opposing reggae sound systems pit their skills against each other. Sound clashes take place in a variety of venues, both indoors and outdoors. Primarily featuring reggae (or dancehall) music, the object is to beat or ‘kill’ their competitors. In the early days of sound clashes, in Jamaican dancehall culture, sound systems would bring their own sound equipment–heavy bass sounds (that can be heard miles away) are especially important. A strong selection of contemporary, popular dubs is necessary also; sometimes sound systems paid artists for the exclusive use of dubs. Usually the Sound systems in the sound clash will play for a set time, perhaps 30 minutes before switching. This time interval gets shorter and shorter, so when playing returns to one sound again, they may only play a shorter time. Near the end of the clash they go song on song or ‘Dub fi dub.’
In Jamaica, sound clashes with their ‘violently martial ethos’ date back at least to the 1950s, when sound systems like Tom the Great Sebastian and Duke Reid’s the Trojan clashed in the old Back-O-Wall neighborhood of Kingston (now Tivoli Gardens). Sometimes these clashes were violent, with one system destroying the other system’s equipment. Sound clashes are an integral part of black culture in London as portrayed in the cult movie Babylon, at the same time that real-life sound systems such as Jah Shaka and Ital Lion were competing for supremacy in Deptford which is in The London Borough of Lewisham a traditional West-Indian area of South London.

A sound system is a group of DJs and engineers contributing and working together as one, playing and producing music. The sound system concept originated in the 1950s in Kingston, Jamaica. DJs would load up a truck with a generator, turntables, and speakers to set up street parties.
The sound system scene is generally regarded as an important part of Jamaican cultural history and as responsible for the rise of modern Jamaican musical styles such as ska, rocksteady, reggae, and dub.

A tiger team is a group of experts assigned to investigate and/or solve technical or systemic problems. The term may have originated in aerospace design but is also used in other settings, including information technology and emergency management. It has been described as ‘a team of undomesticated and uninhibited technical specialists, selected for their experience, energy, and imagination, and assigned to track down relentlessly every possible source of failure in a spacecraft subsystem.’ In security work, a tiger team is a specialized group that tests an organization’s ability to protect its assets by attempting to circumvent, defeat, or otherwise thwart that organization’s internal and external security. The term originated within the military to describe a team whose purpose is to penetrate security of ‘friendly’ installations to test security measures. It now more generally refers to any team that attacks a problem aggressively.
Many tiger teams are informally constituted through managerial edicts. One of these was set up in NASA circa 1966 to solve the ‘Apollo Navigation Problem. Technology at the time was unable to navigate Apollo at the level of precision mandated by the mission planners. Tests using radio tracking data were revealing errors of 2000 meters instead of the 200 that the mission required to safely land Apollo when descending from its lunar orbit. Five tiger teams were set up to find and correct the problem, one at each NASA center, from CalTech JPL in the west to Goddard SFC in the east. The Russians via Luna 10 were also well aware of this problem. The JPL found a solution in 1968; the problem was caused by the unexpectedly large local gravity anomalies on the moon arising from large ringed maria, mountain ranges and craters on the moon. This also led to the construction of the first detailed gravimetric map of a body other than the earth and the discovery of the lunar mass concentrations.

Hack value is the notion among hackers that something is worth doing or is interesting. This is something that hackers often feel intuitively about a problem or solution; the feeling approaches the spiritual for some. An aspect of hack value is performing feats for the sake of showing that they can be done, even if others think it is difficult. Using things in a unique way outside their intended purpose is often perceived as having hack value. Examples are using a matrix printer to produce musical notes, using a flatbed scanner to take ultra-high-resolution photographs or using an optical mouse as barcode reader.
A solution or feat implies hack value if it is done in a way that has finesse or ingenuity. So creativity is an important part of the meaning. For example, picking a difficult lock has hack value; smashing a lock does not. By way of another example, proving Fermat’s last theorem by linking together most of modern mathematics has hack value; solving the four color map problem by exhaustively trying all possibilities does not (both of these have now in fact been proven).

A kludge [klooj] is a workaround, a quick-and-dirty solution, a clumsy or inelegant, yet effective, solution to a problem, typically using parts that are cobbled together. The present word has alternate spellings (kludge and kluge) and pronunciations (rhyming with fudge and stooge respectively), and several proposed etymologies.
Kluge was common Navy slang in the WWII era for any piece of electronics that worked well on shore but consistently failed at sea. In aerospace design a kluge was a temporary design using separate commonly available components that were not flight worthy to proof the design.

Grey goo is a hypothetical end-of-the-world scenario involving nanotechnology in which out-of-control self-replicating robots consume all matter on Earth while building more of themselves, a scenario known as ecophagy (‘eating the environment’).
Self-replicating machines of the macroscopic variety were originally described by mathematician John von Neumann, and are sometimes referred to as von Neumann machines.

Cyberdelic refers to immersion in cyberspace as a psychedelic experience; the fusion of cyberculture and the psychedelic subculture; psychedelic art created by calculating fractal objects; and trance music parties. Timothy Leary, an advocate of psychedelic drug use who became a cult figure of the hippies in the 1960s, reemerged in the 1980s as a spokesperson of the cyberdelic counterculture, whose adherents called themselves ‘cyberpunks,’ and became one of the most philosophical promoters of personal computers, the Internet, and immersive virtual reality. Leary proclaimed that the ‘PC is the LSD of the 1990s’ and admonished bohemians to ‘turn on, boot up, jack in.’
In contrast to the hippies of the 60s who were decidedly antiscience and antitechnology, the cyberpunks of the 80s and 90s ecstatically embraced technology and the hacker ethic. They believed that high technology (and smart drugs) could help human beings overcome all limits, that it could liberate them from authority and even enable them to transcend space, time, and body. They often expressed their ethos and aesthetics through cyberart and reality hacking.

Ray Kurzweil (b. 1948) is an American author, inventor and futurist. He is involved in fields such as optical character recognition (OCR), text-to-speech synthesis, speech recognition technology, and electronic keyboard instruments. He is the author of several books on health, artificial intelligence (AI), transhumanism, the technological singularity, and futurism.
Ray Kurzweil grew up in Queens, NY. He was born to secular Jewish parents who had escaped Austria just before the onset of World War II, and he was exposed via Unitarian Universalism to a diversity of religious faiths during his upbringing. His father was a musician and composer and his mother was a visual artist. His uncle, an engineer at Bell Labs, taught young Ray the basics of computer science.

American author, inventor and futurist Raymond Kurzweil has become well known for predicting the future of artificial intelligence and the human race. His first book, ‘The Age of Intelligent Machines,’ published in 1990, put forth his theories on the results of the increasing use of technology and notably foresaw the explosive growth in the internet, among other predictions.
Later works, 1999’s ‘The Age of Spiritual Machines’ and 2005’s ‘The Singularity is Near’ outlined other theories including the rise of clouds of nano-robots (nanobots) called foglets and the development of Human Body 2.0 and 3.0, whereby nanotechnology is incorporated into many internal organs.

Pseudoscience refers to concepts that are presented as scientific, but which do not adhere to a valid scientific method, or cannot be reliably tested. Pseudoscience is often characterized by the use of vague, exaggerated or unprovable claims, an over-reliance on confirmation rather than rigorous attempts at refutation, a lack of openness to evaluation by other experts, and a general absence of systematic processes to rationally develop theories. So-called ‘Pop science’ blurs the divide between science and pseudoscience among the general public, and may also involve science fiction (it is disseminated to, and can also easily emanate from, persons not accountable to scientific methodology and expert peer review).
Pseudoscientific beliefs are widespread, even among public school science teachers and newspaper reporters. The demarcation problem between science and pseudoscience has ethical political implications (as well as philosophical and scientific). Differentiating science from pseudoscience has practical implications in the case of health care, expert testimony, environmental policies, and science education. Distinguishing scientific facts and theories from pseudoscientific beliefs such as those found in astrology, medical quackery, and occult beliefs combined with scientific concepts, is part of science education and scientific literacy.

MacGyver is an American action-adventure television series, where the titular character employs his resourcefulness and knowledge of chemistry, physics, technology, and survival skills to resolve what are often life-or-death crises. He creates inventions from simple items to solve these problems. These inventions became synonymous with the character and were called MacGyverisms by fans. MacGyver was unlike secret agents in other television series and films because, instead of relying on high-tech weapons and tools, he carried only a Swiss Army knife and duct tape but never a gun. A boyhood friend of his was accidentally killed by a revolver, and MacGyver has avoided them since.
The show’s writers based MacGyver’s inventions on items they found on location, concepts from scientific advisers John Koivula and Jim Green, and real events. The show also offered a monetary prize to people who sent good ideas for the show. A young fan suggested that MacGyver could patch up a vehicle’s radiator by cracking an egg into it, and the episode ‘Bushmaster’ was constructed around this trick.
