The Isetta is an Italian-designed microcar built under license in a number of different countries, including Argentina, Spain, Belgium, France, Brazil, Germany, and the United Kingdom. Because of its egg shape and bubble-like windows, it became known as a bubble car, a name also given to other similar vehicles.

In 1955, the BMW Isetta became the world's first mass-production car to achieve a fuel consumption of 3 L/100 km (94 mpg_‑imp; 78 mpg_‑US). It was the top-selling single-cylinder car in the world, with 161,728 units sold.

Initially manufactured by the Italian firm Iso SpA, the name Isetta is the Italian diminutive form of Iso, meaning "little Iso".

🔗 United States 🔗 Biography 🔗 Death 🔗 Criminal Biography 🔗 African diaspora 🔗 United States/South Carolina

George Junius Stinney, Jr. (October 21, 1929 – June 16, 1944), was an African American child who was convicted, in a proceeding later vacated as an unfair trial, of murdering two white girls, ages 7 and 11, in his hometown of Alcolu, South Carolina. He was executed by electric chair in June 1944. Stinney is the youngest American to be sentenced to death and executed.

A re-examination of the Stinney case began in 2004, and several individuals and Northeastern University School of Law sought a judicial review. His conviction was overturned in 2014, 70 years after he was executed when a court ruled that he had not received a fair trial.

🔗 Architecture 🔗 Materials

Foam concrete, also known as Lightweight Cellular Concrete (LCC), Low Density Cellular Concrete (LDCC), and other terms is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar. As mostly no coarse aggregate is used for production of foam concrete the correct term would be called mortar instead of concrete; it may be called "foamed cement" as well. The density of foam concrete usually varies from 400 kg/m³ to 1600 kg/m³. The density is normally controlled by substituting fully or part of the fine aggregate with foam.

🔗 Economics 🔗 Business 🔗 International development

The O-ring theory of economic development is a model of economic development put forward by Michael Kremer in 1993, which proposes that tasks of production must be executed proficiently together in order for any of them to be of high value. The key feature of this model is positive assortative matching, whereby people with similar skill levels work together.

The name comes from the 1986 Challenger shuttle disaster, a catastrophe caused by the failure of a single O-ring.

Kremer thinks that the O-ring development theory explains why rich countries produce more complicated products, have larger firms and much higher worker productivity than poor countries.

🔗 Computing

Personal knowledge management (PKM) is a process of collecting information that a person uses to gather, classify, store, search, retrieve and share knowledge in their daily activities (Grundspenkis 2007) and the way in which these processes support work activities (Wright 2005). It is a response to the idea that knowledge workers need to be responsible for their own growth and learning (Smedley 2009). It is a bottom-up approach to knowledge management (KM) (Pollard 2008).

🔗 Philosophy 🔗 Philosophy/Logic 🔗 Philosophy/Epistemology

The unexpected hanging paradox or hangman paradox is a paradox about a person's expectations about the timing of a future event which they are told will occur at an unexpected time. The paradox is variously applied to a prisoner's hanging, or a surprise school test. It could be reduced to be Moore's paradox.

Despite significant academic interest, there is no consensus on its precise nature and consequently a final correct resolution has not yet been established. Logical analysis suggests that the problem arises in a self-contradictory self-referencing statement at the heart of the judge's sentence. Epistemological studies of the paradox have suggested that it turns on our concept of knowledge. Even though it is apparently simple, the paradox's underlying complexities have even led to its being called a "significant problem" for philosophy.

🔗 Novels

In the dystopian novel Nineteen Eighty-Four (1949), by George Orwell, the Two Minutes Hate is the daily, public period during which members of the Outer Party of Oceania must watch a film depicting the enemies of the state, specifically Emmanuel Goldstein and his followers, to openly and loudly express hatred for them. The political purpose of the Two Minutes Hate is to allow the citizens of Oceania to vent their existential anguish and personal hatreds towards politically expedient enemies: Goldstein and the enemy superstate of the moment. In re-directing the members' subconscious feelings away from the Party's government of Oceania, and towards non-existent external enemies, the Party minimises thoughtcrime and the consequent, subversive behaviours of thoughtcriminals.

A Malthusian catastrophe (also known as Malthusian check, Malthusian crisis, Malthusian spectre or Malthusian crunch) occurs when population growth outpaces agricultural production.

Tadeusz Kościuszko (1746–1817), a prominent figure in the history of the Polish-Lithuanian Commonwealth and the American Revolution, made several wills, notably one in 1798 stipulating that the proceeds of his American estate be spent on freeing and educating African-American slaves, including those of his friend Thomas Jefferson, whom he named as the will's executor. Jefferson refused the executorship and the will was beset by legal complications, including the discovery of later wills. Jefferson's refusal incited discussion in the 19th, 20th, and 21st centuries. Kościuszko returned to Europe in 1798 and lived there until his 1817 death in Switzerland. In the 1850s, what was left of the money in Kościuszko's U.S. trust was turned over by the U.S. Supreme Court to his heirs in Europe.
