🔗 Physics

Magnetocapacitance is a property of some dielectric, insulating materials, and metal–insulator–metal heterostructures that exhibit a change in the value of their capacitance when an external magnetic field is applied to them. Magnetocapacitance can be an intrinsic property of some dielectric materials, such as multiferroic compounds like BiMnO₃, or can be a manifest of properties extrinsic to the dielectric but present in capacitance structures like Pd, Al₂O₃, and Al.

A Matrioshka brain is a hypothetical megastructure of immense computational capacity powered by a Dyson sphere. It was proposed in 1997 by Robert J. Bradbury (1956–2011). It is an example of a Class B stellar engine, employing the entire energy output of a star to drive computer systems. This concept derives its name from the nesting Russian Matryoshka dolls. The concept was deployed by Bradbury in the anthology Year Million: Science at the Far Edge of Knowledge.

🔗 Biography

Shanti Devi (11 December 1926 – 27 December 1987) was an Indian woman who claimed to remember her past life, and became the subject of reincarnation research. A commission set up by the Indian political leader Mahatma Gandhi supported her claim, while another report by researcher Bal Chand Nahata disputed it. Subsequently, several other researchers interviewed her, and published articles and books about her.

"Computer says no" is a catchphrase first used in the British sketch comedy television programme Little Britain in 2004. In British culture, the phrase is used to criticise public-facing organisations and customer service staff who rely on information stored on or generated by a computer to make decisions and respond to customers' requests, often in a manner which goes against common sense. It may also refer to a deliberately unhelpful attitude towards customers and service-users commonly experienced within British society, whereby more could be done to reach a mutually satisfactory outcome, but is not.

Agnès Varda (French: [aɲɛs vaʁda]; born Arlette Varda; 30 May 1928 – 29 March 2019) was a Belgian-born French film director, screenwriter, photographer, and artist. Her pioneering work was central to the development of the widely influential French New Wave film movement of the 1950s and 1960s. Her films focused on achieving documentary realism, addressing women's issues, and other social commentary, with a distinctive experimental style.

Varda's work employed location shooting in an era when the limitations of sound technology made it easier and more common to film indoors, with constructed sets and painted backdrops of landscapes, rather than outdoors, on location. Her use of non-professional actors was also unconventional for 1950s French cinema. Varda's feature film debut was La Pointe Courte (1955), followed by Cléo from 5 to 7 (1962), one of her most notable narrative films, Vagabond (1985), and Kung Fu Master (1988). Varda was also known for her work as a documentarian with such works as Black Panthers (1968), The Gleaners and I (2000), The Beaches of Agnès (2008), Faces Places (2017), and her final film, Varda by Agnès (2019).

Director Martin Scorsese described Varda as "one of the Gods of Cinema". Among several other accolades, Varda received an Honorary Palme d'Or at the 2015 Cannes Film Festival, becoming the first woman to win the award, a Golden Lion for Vagabond at the 1985 Venice Film Festival, an Academy Honorary Award, and a nomination for the Academy Award for Best Documentary Feature for Faces Places, becoming the oldest person to be nominated for a competitive Oscar. In 2017, she became the first female director to win an honorary Oscar.

Depopulation of cockroaches in post-Soviet states refers to observations that there has been a rapid disappearance of various types of cockroaches since the beginning of the 21st century in Russia and other countries of the former USSR. Various factors have been suggested as causes of the depopulation.

The Law of Demeter (LoD) or principle of least knowledge is a design guideline for developing software, particularly object-oriented programs. In its general form, the LoD is a specific case of loose coupling. The guideline was proposed by Ian Holland at Northeastern University towards the end of 1987, and can be succinctly summarized in each of the following ways:

• Each unit should have only limited knowledge about other units: only units "closely" related to the current unit.
• Each unit should only talk to its friends; don't talk to strangers.
• Only talk to your immediate friends.

The fundamental notion is that a given object should assume as little as possible about the structure or properties of anything else (including its subcomponents), in accordance with the principle of "information hiding". It may be viewed as a corollary to the principle of least privilege, which dictates that a module possess only the information and resources necessary for its legitimate purpose.

It is so named for its origin in the Demeter Project, an adaptive programming and aspect-oriented programming effort. The project was named in honor of Demeter, “distribution-mother” and the Greek goddess of agriculture, to signify a bottom-up philosophy of programming which is also embodied in the law itself.

Crimson Contagion was a simulation administered by the U.S. Department of Health and Human Services from January to August 2019 that tested the capacity of the U.S. federal government and twelve U.S. states to respond to a severe influenza pandemic originating in China. The exercise involves a scenario in which tourists returning from China spread a respiratory virus in the United States, beginning in Chicago. In less than two months the virus had infected 110 million Americans, killing more than half a million. The report issued at the conclusion of the exercise outlines the government's limited capacity to respond to a pandemic, with federal agencies lacking the funds, coordination, and resources to facilitate an effective response to the virus.

Black MIDI is a music genre consisting of compositions that use MIDI files to create a song or a remix containing a large number of notes, typically in the thousands, millions, billions, or even trillions. People who make black MIDIs are known as blackers. However, there are no specific criteria of what is considered "black"; as a result, pinpointing the exact origin of black MIDI is impossible.

BerkShares is a local currency that circulates in The Berkshires region of Massachusetts. It was launched on September 29, 2006 by BerkShares Inc., with research and development assistance from the Schumacher Center for a New Economics. The BerkShares website lists around 400 businesses in Berkshire County that accept the currency. Since launch, over 10 million BerkShares have been issued from participating branch offices of local banks (as of February 2020, 9 branches of 3 different banks). The bills were designed by John Isaacs and were printed by Excelsior Printing on special paper with incorporated security features from Crane & Co.. BerkShares are pegged with an exchange rate to the US dollar, but the Schumacher Center has discussed the possibility of pegging its value to a basket of local goods in order to insulate the local economy against volatility in the US economy.
