Vivian Dorothy Maier (February 1, 1926 – April 21, 2009) was an American street photographer whose work was not discovered and recognized until after her death. She worked for about forty years as a nanny, mostly in Chicago's North Shore, while she pursued her photography. She took more than 150,000 photographs during her lifetime, primarily of the people and architecture of Chicago, New York City, and Los Angeles, although she also traveled and photographed worldwide.

During her lifetime, Maier's photographs were unknown and unpublished; many of her negatives were never printed. A Chicago collector, John Maloof, acquired some of Maier's photos in 2007, while two other Chicago-based collectors, Ron Slattery and Randy Prow, also found some of Maier's prints and negatives in her boxes and suitcases around the same time. Maier's photographs were first published on the Internet in July 2008, by Slattery, but the work received little response. In October 2009, Maloof linked his blog to a selection of Maier's photographs on the image-sharing website Flickr, and the results went viral, with thousands of people expressing interest. Maier's work subsequently attracted critical acclaim, and since then, Maier's photographs have been exhibited around the world.

Her life and work have been the subject of books and documentary films, including the film Finding Vivian Maier (2013), which premiered at the Toronto International Film Festival, and was nominated for the Academy Award for Best Documentary Feature at the 87th Academy Awards.

🔗 Aviation 🔗 Physics 🔗 Physics/Fluid Dynamics

In aviation, a phugoid or fugoid ( ) is an aircraft motion in which the vehicle pitches up and climbs, and then pitches down and descends, accompanied by speeding up and slowing down as it goes "downhill" and "uphill". This is one of the basic flight dynamics modes of an aircraft (others include short period, roll subsidence, dutch roll, and spiral divergence).

🔗 Freedom of speech 🔗 Journalism 🔗 Singapore

"Disneyland with the Death Penalty" is a 4,500-word article about Singapore written by William Gibson. His first major piece of non-fiction, it was first published as the cover story for Wired magazine's September/October 1993 issue (1.4).

The article follows Gibson's observations of the architecture, phenomenology and culture of Singapore, and the clean, bland and conformist impression the city-state conveys during his stay. Its title and central metaphor—Singapore as Disneyland with the death penalty—is a reference to the authoritarian artifice the author perceives the city-state to be. Singapore, Gibson details, is lacking any sense of creativity or authenticity, absent of any indication of its history or underground culture. He finds the government to be pervasive, corporatist and technocratic, and the judicial system rigid and draconian. Singaporeans are characterized as consumerists of insipid taste. The article is accentuated by local news reports of criminal trials by which the author illustrates his observations, and bracketed by contrasting descriptions of the Southeast Asian airports he arrives and leaves by.

Though Gibson's first major piece of non-fiction, the article had an immediate and lasting impact. The Singaporean government banned Wired upon the publication of the issue. The phrase "Disneyland with the death penalty" came to stand internationally for an authoritarian and austere reputation that the city-state found difficult to shake off.

Vantablack is a material developed by Surrey NanoSystems in the United Kingdom and is one of the darkest substances known, absorbing up to 99.965% of visible light (at 663 nm if the light is perpendicular to the material).

The name is a compound of the acronym VANTA (vertically aligned nanotube arrays) and the color black.

🔗 California 🔗 Crime

The 1999 Loomis truck robbery was a robbery of a Loomis, Fargo & Co. semi-trailer truck on March 24, 1999, as it transported money from Sacramento, California to San Francisco. At some point during the transit, one or more robbers boarded the truck, cut a hole in the roof, removed approximately 2.3 million dollars, and exited the truck with the money, completely evading detection by the truck's driver and guards. The robbery was not discovered until after the truck arrived at its destination. No suspects were ever identified by authorities and the robbery is now a cold case. Even the exact tools and methods used by robber or robbers were never conclusively determined.

🔗 Psychology

In psychology, the four stages of competence, or the "conscious competence" learning model, relates to the psychological states involved in the process of progressing from incompetence to competence in a skill. People may have several skills, some unrelated to each other, and each skill will typically be at one of the stages at a given time. Many skills require practice to remain at a high level of competence.

The four stages suggest that individuals are initially unaware of how little they know, or unconscious of their incompetence. As they recognize their incompetence, they consciously acquire a skill, then consciously use it. Eventually, the skill can be utilized without it being consciously thought through: the individual is said to have then acquired unconscious competence.

🔗 Computing 🔗 Electronics 🔗 Electrical engineering

An asynchronous circuit, or self-timed circuit, is a sequential digital logic circuit which is not governed by a clock circuit or global clock signal. Instead it often uses signals that indicate completion of instructions and operations, specified by simple data transfer protocols. This type of circuit is contrasted with synchronous circuits, in which changes to the signal values in the circuit are triggered by repetitive pulses called a clock signal. Most digital devices today use synchronous circuits. However asynchronous circuits have the potential to be faster, and may also have advantages in lower power consumption, lower electromagnetic interference, and better modularity in large systems. Asynchronous circuits are an active area of research in digital logic design.

Ronald James Read (October 23, 1921 – June 2, 2014) was an American philanthropist, investor, janitor, and gas station attendant. Read grew up in Dummerston, Vermont, in an impoverished farming household. He walked or hitchhiked 4 mi (6.4 km) daily to his high school and was the first high school graduate in his family. He enlisted in the United States Army during World War II, serving in Italy as a military policeman. Upon an honorable discharge from the military in 1945, Read returned to Brattleboro, Vermont, where he worked as a gas station attendant and mechanic for about 25 years. Read retired for one year and then took a part-time janitor job at J. C. Penney where he worked for 17 years until 1997.

Read died in 2014. He received media coverage in numerous newspapers and magazines after bequeathing US$1.2 million to Brooks Memorial Library and $4.8 million to Brattleboro Memorial Hospital. Read amassed a fortune of almost $8 million by investing in dividend-producing stocks, avoiding the stocks of companies he did not understand such as technology companies, living frugally, and being a buy and hold investor in a diversified portfolio of stocks with a heavy concentration in blue chip companies.

🔗 Marketing & Advertising 🔗 Linguistics

A thought-terminating cliché (also known as a semantic stop-sign, a thought-stopper, bumper sticker logic, or cliché thinking) is a form of loaded language, commonly used to quell cognitive dissonance. Depending on context in which a phrase (or cliché) is used, it may actually be valid and not qualify as thought-terminating; it does qualify as such when its application intends to dismiss dissent or justify fallacious logic. Its only function is to stop an argument from proceeding further, in other words "end the debate with a cliche... not a point." The term was popularized by Robert Jay Lifton in his 1961 book Thought Reform and the Psychology of Totalism, who called the use of the cliché, along with "loading the language", as "The language of Non-thought".
