Modelica is an object-oriented, declarative, multi-domain modeling language for component-oriented modeling of complex systems, e.g., systems containing mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented subcomponents. The free Modelica language is developed by the non-profit Modelica Association. The Modelica Association also develops the free Modelica Standard Library that contains about 1360 generic model components and 1280 functions in various domains, as of version 3.2.1.

🔗 Physics

Isaac Newton's rotating bucket argument (also known as Newton's bucket) was designed to demonstrate that true rotational motion cannot be defined as the relative rotation of the body with respect to the immediately surrounding bodies. It is one of five arguments from the "properties, causes, and effects" of "true motion and rest" that support his contention that, in general, true motion and rest cannot be defined as special instances of motion or rest relative to other bodies, but instead can be defined only by reference to absolute space. Alternatively, these experiments provide an operational definition of what is meant by "absolute rotation", and do not pretend to address the question of "rotation relative to what?" General relativity dispenses with absolute space and with physics whose cause is external to the system, with the concept of geodesics of spacetime.

🔗 Literature

"Belling the Cat" is a fable also known under the titles "The Bell and the Cat" and "The Mice in Council". Although often attributed to Aesop, it was not recorded before the Middle Ages and has been confused with the quite different fable of Classical origin titled The Cat and the Mice. In the classificatory system established for the fables by B. E. Perry, it is numbered 613, which is reserved for Mediaeval attributions outside the Aesopic canon.

The Hayes command set (also known as the AT command set) is a specific command language originally developed by Dale Heatherington and Dennis Hayes for the Hayes Smartmodem in 1981.

The command set consists of a series of short text strings that can be combined to produce commands for operations such as dialing, hanging up, and changing the parameters of the connection. The vast majority of dial-up modems use the Hayes command set in numerous variations.

The command set covered only those operations supported by the earliest 300 bit/s modems. When new commands were required to control additional functionality in higher-speed modems, a variety of one-off standards emerged from each of the major vendors. These continued to share the basic command structure and syntax, but added any number of new commands using some sort of prefix character – & for Hayes and USRobotics, and \ for Microcom, for instance. Many of these were re-standardized on the Hayes extensions after the introduction of the SupraFAXModem 14400 and the market consolidation that followed.

The term Hayes compatible was and as of 2018 still is important within the industry.

John Titor (May 5, 6 or 7, 1998) is a name used on several bulletin boards during 2000 and 2001 by a poster claiming to be an American military time traveler from 2036. Titor made numerous vague and specific predictions regarding calamitous events in 2004 and beyond, including a nuclear war, none of which came true. Subsequent closer examination of Titor's assertions provoked widespread skepticism. Inconsistencies in his explanations, the uniform inaccuracy of his predictions, and a private investigator's findings all led to the general impression that the entire episode was an elaborate hoax. A 2009 investigation concluded that Titor was likely the creation of Larry Haber, a Florida entertainment lawyer, along with his brother Morey, a computer scientist.

🔗 Germany 🔗 Formula One

The 1957 German Grand Prix was a Formula One motor race held on 4 August 1957 at Nürburgring. It was race 6 of 8 in the 1957 World Championship of Drivers. The 22 lap race was won by Juan Manuel Fangio, and is often cited as one of the greatest victories in racing history. It was Fangio's fourth victory out of the seven races in the season contested by Formula 1 cars - excluding the Indianapolis 500, in which only US drivers competed, using USAC Championship cars. Furthermore, due to the number of points he had accumulated in the season (34 to Luigi Musso's 16), his victory at the Nürburgring mathematically clinched Fangio's fifth World Championship title with two races to go. The race was also notable for being Fangio's 24th and last victory in F1; his career still stands as having the highest win percentage ever, with 46.15% of his 52 race entries being wins.

Two members of eBay's Executive Leadership Team who were implicated in the scandal were not charged.

A stick bomb is a (mechanical) spring-loaded device constructed out of flat sticks woven together under a bending moment. Other names for stick bombs include Chinese stick puzzles, Cobra wave, and frame bombs. Stick bombs are created for fun and as art, not for any practical use.

🔗 Women's History 🔗 Gender Studies 🔗 Albania 🔗 LGBTQ+ studies

A sworn virgin is a traditional gender variant or third gender social role in certain Balkan cultures, consisting of people who are assigned female at birth but take a vow of chastity and live the rest of their lives socially recognized as men. The practice is most common in patriarchal northern Albania, Kosovo and Montenegro, where burrnesha are recognized under the tribal Kanun law, but also exists, or has existed, to a lesser extent in other parts of the western Balkans, including Bosnia, Dalmatia (Croatia), Serbia and North Macedonia.

In times when women had a prescribed role, burrnesha gave up their preexisting sexual, reproductive and social identities to acquire the same freedoms as men. They could dress as men, be head of the household, move freely in social situations, and take work traditionally open only to men. National Geographic's Taboo estimated in 2002 that there were fewer than 102 Albanian sworn virgins left. As of 2022, while there were no exact figures, twelve burrnesha were estimated to remain in Northern Albania and Kosovo.

Mr. Big (sometimes known as the Canadian technique) is a covert investigation procedure used by undercover police to elicit confessions from suspects in cold cases (usually murder). Police officers create a fictitious grey area or criminal organization and then seduce the suspect into joining it. They build a relationship with the suspect, gain their confidence, and then enlist their help in a succession of criminal acts (e.g., delivering goods, credit card scams, selling guns) for which they are paid. Once the suspect has become enmeshed in the criminal gang, they are persuaded to divulge information about their criminal history, usually as a prerequisite for being accepted as a member of the organization.

The Mr. Big technique was developed by the Royal Canadian Mounted Police (RCMP) in British Columbia, with the first documented case taking place in March of 1965 during the investigation of David Louis Harrison, a former Vancouver police constable who was tried and convicted for taking part in the robbery of $1.2 million of cancelled currency from the Canadian Pacific Merchandise Services warehouse in Vancouver. Harrison was convicted using evidence gained by Cpl. Allan Richards, posing as crime syndicate hoodlum John Clarke, and his sting partner, police operative Al Brooks. Harrison testified that he believed John Clarke was a violent syndicate hoodlum. Harrison further testified that Clarke was often packing a gun, that Clarke carried a vial of nitroglycerine around his neck that he would throw at a police car if it got too close to him, and that he was afraid he would be harmed if he didn’t play along.

The Mr. Big tactic has been used in more than 350 cases across Canada as of 2008. The RCMP claims that the person of interest was either cleared or charged in 75% of cases (the rest remaining unresolved and requiring further investigation). Of the cases prosecuted, an estimated 95% result in a conviction.

The use of this technique is essentially prohibited in some countries, including the United Kingdom and the United States. In Germany, which has high standards for what constitutes a voluntary confession, it may be more difficult to use confessions obtained by this technique. The procedure has been used by police in Australia and New Zealand, and its use has been upheld by courts in both countries.
