The Wingless Electromagnetic Air Vehicle (WEAV) is a heavier than air flight system developed at the University of Florida, funded by the Air Force Office of Scientific Research. The WEAV was invented in 2006 by Dr. Subrata Roy, plasma physicist, aerospace engineering professor at the University of Florida, and has been a subject of several patents. The WEAV employs no moving parts, and combines the aircraft structure, propulsion, energy production and storage, and control subsystems into one integrated system.

🔗 Biography 🔗 Death 🔗 Skepticism

Gloria Ramirez (January 11, 1963 – February 19, 1994) was a woman from Riverside, California who was dubbed "the Toxic Lady" or "the Toxic Woman" by the media when several hospital workers became ill after exposure to her body and blood. She had been admitted to the emergency department while suffering from late-stage cervical cancer. While treating Ramirez, several hospital workers fainted and others experienced symptoms such as shortness of breath and muscle spasms. Five workers required hospitalization, one of whom remained in an intensive care unit for two weeks.

Shortly after arriving at the hospital, Ramirez died from complications related to cancer. The incident was initially considered to be a case of mass hysteria. An investigation by Lawrence Livermore National Laboratory proposed that Ramirez had been self-administering dimethyl sulfoxide as a treatment for pain, which converted into dimethyl sulfate, an extremely poisonous and highly carcinogenic alkylating agent, via a series of chemical reactions in the emergency department. Although this theory has been endorsed by the Riverside Coroner's Office and published in the journal Forensic Science International, it is still a matter of debate in the scientific community.

🔗 Biography 🔗 Africa 🔗 BBC 🔗 Africa/Republic of the Congo

Guy Goma (born 1969) is a Congolese-French business studies graduate from Brazzaville in the Republic of the Congo who was accidentally interviewed live on BBC News 24, a UK television news station, on Monday 8 May 2006. Goma was mistaken for technology expert Guy Kewney when he attended the BBC for a job interview and was brought onto a BBC special regarding the case Apple Corps v Apple Computer to provide insight on a subject he knew little about.

Goma became well known for the incident, which is noted as a memorable TV moment.

🔗 Companies 🔗 Germany 🔗 Transport 🔗 Energy 🔗 Transport/Maritime 🔗 Ships

SkySails GmbH & Co. KG is a Hamburg-based company that sells kite rigs to propel cargo ships, large yachts and fishing vessels by wind energy. Ships are pulled by an automatically-controlled foil kite of some hundreds of square meters. For multiple reasons, they give many times the thrust per unit area of conventional mast-mounted sails.

The systems save fuel, and reduce carbon emissions and shipping costs, but have not been widely adopted.

🔗 Visual arts 🔗 Belgium

Children's Games is an oil-on-panel by Flemish Renaissance artist Pieter Bruegel the Elder, painted in 1560. It is currently held and exhibited at the Kunsthistorisches Museum in Vienna. The entire composition is full of children playing a wide variety of games. Over 90 different games that were played by children at the time have been identified.

🔗 Physics

In physics, the fourth, fifth and sixth derivatives of position are defined as derivatives of the position vector with respect to time – with the first, second, and third derivatives being velocity, acceleration, and jerk, respectively. Unlike the first three derivatives, the higher-order derivatives are less common, thus their names are not as standardized, though the concept of a minimum snap trajectory has been used in robotics and is implemented in MATLAB.

The fourth derivative is often referred to as snap or jounce. The name "snap" for the fourth derivative led to crackle and pop for the fifth and sixth derivatives respectively, inspired by the Rice Krispies mascots Snap, Crackle, and Pop. These terms are occasionally used, though "sometimes somewhat facetiously".

🔗 Internet culture 🔗 Economics

You'll own nothing and be happy (alternatively you'll own nothing and you'll be happy) is a phrase originated by Danish Politician Ida Auken in a 2016 essay for the World Economic Forum. After appearing in a WEF video in 2016, the phrase began to be used by critics of the World Economic Forum (WEF) who accuse the WEF of desiring restrictions on ownership of private property.
