The Kobayashi Maru is a training exercise in the fictional Star Trek universe designed to test the character of Starfleet Academy cadets in a no-win scenario. The Kobayashi Maru test was first depicted in the opening scene of the film Star Trek II: The Wrath of Khan and also appears in the 2009 film Star Trek. Screenwriter Jack B. Sowards is credited with inventing the test. The test's name is occasionally used among Star Trek fans or those familiar with the series to describe a no-win scenario, a test of one's character or a solution that involves redefining the problem and managing an insurmountable scenario gracefully.

The notional primary goal of the exercise is to rescue the civilian vessel Kobayashi Maru in a simulated battle with the Klingons. The disabled ship is located in the Klingon Neutral Zone, and any Starfleet ship entering the zone would cause an interstellar border incident. The approaching cadet crew must decide whether to attempt rescue of the Kobayashi Maru crew—endangering their own ship and lives—or leave the Kobayashi Maru to certain destruction. If the cadet chooses to attempt rescue, the simulation is designed to guarantee that the cadet's ship enters a situation that he or she will have absolutely no chance of winning, escaping, negotiating or even surviving.

🔗 Biography 🔗 Hungary 🔗 Women writers 🔗 Translation studies

Kató Lomb (Pécs, February 8, 1909 – Budapest, June 9, 2003) was a Hungarian interpreter, translator and one of the first simultaneous interpreters in the world. Originally she graduated in physics and chemistry, but her interest soon led her to languages. Native in Hungarian, she was able to interpret fluently in nine or ten languages (in four of them even without preparation), and she translated technical literature and read belles-lettres in six languages.She was able to understand journalism in further eleven languages. As she put it, altogether she earned money with sixteen languages (Bulgarian, Chinese, Danish, English, French, German, Hebrew, Italian, Japanese, Latin, Polish, Romanian, Russian, Slovak, Spanish, Ukrainian). She learned these languages mostly by self-effort, as an autodidact. Her aims to acquire these languages were most of all practical, to satisfy her interest.

According to her own account, her long life was highlighted not primarily by the command of languages but the actual study of them. Through her books, published in Hungarian in several editions as well as in some other languages, interviews (in print and on the air) and conversations, she tried to share this joy with generations. As an interpreter, she visited five continents, saw forty countries, and reported about her experiences and adventures in a separate book (Egy tolmács a világ körül, "An interpreter around the world").

The practice of mass surveillance in the United States dates back to World War I wartime monitoring and censorship of international communications from, to, or which passed through the United States. After the First World War and the Second World War, the surveillance continued, via programs such as the Black Chamber and Project SHAMROCK. The formation and growth of federal law-enforcement and intelligence agencies such as the FBI, CIA, and NSA institutionalized surveillance used to also silence political dissent, as evidenced by COINTELPRO projects which targeted various organizations and individuals. During the Civil Rights Movement era, many individuals put under surveillance orders were first labelled as integrationists then deemed subversive. Other targeted individuals and groups included Native American activists, African American and Chicano liberation movement activists, and anti-war protesters.

The formation of the international UKUSA surveillance agreement of 1946 evolved into the ECHELON collaboration by 1955 of five English-speaking nations, also known as the Five Eyes, and focused on interception of electronic communications, with substantial increases in domestic surveillance capabilities.

Following the September 11th attacks of 2001, domestic and international mass surveillance capabilities grew immensely. Contemporary mass surveillance relies upon annual presidential executive orders declaring a continued State of National Emergency, first signed by George W. Bush on September 14, 2001 and then continued on an annual basis by President Barack Obama, and upon several subsequent national security Acts including the USA PATRIOT Act and FISA Amendment Act's PRISM surveillance program. Critics and political dissenters currently describe the effects of these acts, orders, and resulting database network of Fusion centers as forming a veritable American police state that simply institutionalized the illegal COINTELPRO tactics used to assassinate dissenters and leaders from the 1950s onwards.

Additional surveillance agencies, such as the DHS and the position of Director of National Intelligence have exponentially escalated mass surveillance since 2001. A series of media reports in 2013 revealed more recent programs and techniques employed by the US intelligence community. Advances in computer and information technology allow the creation of huge national databases that facilitate mass surveillance in the United States by DHS managed Fusion centers, the CIA's Terrorist Threat Integration Center (TTIC) program, and the FBI's TSDB.

Mass surveillance databases are also cited as responsible for profiling Latino Americans and contributing to "self-deportation" techniques, or physical deportations by way of the DHS's ICEGang national database.

After World War I, the US Army and State Department established the Black Chamber, also known as the Cipher Bureau, which began operations in 1919. The Black Chamber was headed by Herbert O. Yardley, who had been a leader in the Army's Military Intelligence program. Regarded as a precursor to the National Security Agency, it conducted peacetime decryption of material including diplomatic communications until 1929.

In the advent of World War II, the Office of Censorship was established. The wartime agency monitored "communications by mail, cable, radio, or other means of transmission passing between the United States and any foreign country". This included the 350,000 overseas cables and telegrams and 25,000 international telephone calls made each week. "Every letter that crossed international or U.S. territorial borders from December 1941 to August 1945 was subject to being opened and scoured for details."

With the end of World War II, Project SHAMROCK was established in 1945. The organization was created to accumulate telegraphic data entering and exiting from the United States. Major communication companies such as Western Union, RCA Global and ITT World Communications actively aided the project, allowing American intelligence officials to gain access to international message traffic. Under the project, and many subsequent programs, no precedent had been established for judicial authorisation, and no warrants were issued for surveillance activities. The project was terminated in 1975.

In 1952, President Harry S. Truman established the National Security Agency (NSA) in 1952 for the purposes of collecting, processing, and monitoring intelligence data. The existence of NSA was not known to people as the memorandum by President Truman was classified.

When the Citizens' Commission to Investigate the FBI published stolen FBI documents revealing abuse of intelligence programs in 1971, Senator Frank Church began an investigation into the programs that become known as the Church Committee. The committee sought to investigate intelligence abuses throughout the 1970s. Following a report provided by the committee outlining egregious abuse, in 1976 Congress established the Senate Select Committee on Intelligence. It would later be joined by the Foreign Intelligence Surveillance Court in 1978. The institutions worked to limit the power of the agencies, ensuring that surveillance activities remained within the rule of law.

Following the attacks of September 11, 2001, Congress passed The Patriot Act to strengthen security and intelligence efforts. The act granted the President broad powers on the war against terror, including the power to bypass the FISA Court for surveillance orders in cases of national security. Additionally, mass surveillance activities were conducted alongside various other surveillance programs under the head of President's Surveillance Program. Under pressure from the public, the warrantless wiretapping program was allegedly ended in January 2007.

Many details about the surveillance activities conducted in the United States were revealed in the disclosure by Edward Snowden in June 2013. Regarded as one of the biggest media leaks in the United States, it presented extensive details about the surveillance programs of the NSA, that involved interception of internet data and telephonic calls from over a billion users, across various countries.

Stuxnet is a malicious computer worm, first uncovered in 2010, thought to have been in development since at least 2005. Stuxnet targets supervisory control and data acquisition (SCADA) systems and is believed to be responsible for causing substantial damage to the nuclear program of Iran. Although neither country has openly admitted responsibility, the worm is widely understood to be a cyberweapon built jointly by the United States and Israel.

Stuxnet specifically targets programmable logic controllers (PLCs), which allow the automation of electromechanical processes such as those used to control machinery and industrial processes including gas centrifuges for separating nuclear material. Exploiting four zero-day flaws, Stuxnet functions by targeting machines using the Microsoft Windows operating system and networks, then seeking out Siemens Step7 software. Stuxnet reportedly compromised Iranian PLCs, collecting information on industrial systems and causing the fast-spinning centrifuges to tear themselves apart. Stuxnet's design and architecture are not domain-specific and it could be tailored as a platform for attacking modern supervisory control and data acquisition (SCADA) and PLC systems (e.g., in factory assembly lines or power plants), most of which are in Europe, Japan, and the US. Stuxnet reportedly ruined almost one-fifth of Iran's nuclear centrifuges. Targeting industrial control systems, the worm infected over 200,000 computers and caused 1,000 machines to physically degrade.

Stuxnet has three modules: a worm that executes all routines related to the main payload of the attack; a link file that automatically executes the propagated copies of the worm; and a rootkit component responsible for hiding all malicious files and processes, to prevent detection of Stuxnet. It is typically introduced to the target environment via an infected USB flash drive, thus crossing any air gap. The worm then propagates across the network, scanning for Siemens Step7 software on computers controlling a PLC. In the absence of either criterion, Stuxnet becomes dormant inside the computer. If both the conditions are fulfilled, Stuxnet introduces the infected rootkit onto the PLC and Step7 software, modifying the code and giving unexpected commands to the PLC while returning a loop of normal operation system values back to the users.

In 2015, Kaspersky Lab noted that the Equation Group had used two of the same zero-day attacks prior to their use in Stuxnet and commented that "the similar type of usage of both exploits together in different computer worms, at around the same time, indicates that the Equation Group and the Stuxnet developers are either the same or working closely together".

🔗 Physics

In quantum field theory, the Casimir effect and the Casimir–Polder force are physical forces arising from a quantized field. They are named after the Dutch physicist Hendrik Casimir who predicted them in 1948.

The Casimir effect can be understood by the idea that the presence of conducting metals and dielectrics alters the vacuum expectation value of the energy of the second quantized electromagnetic field. Since the value of this energy depends on the shapes and positions of the conductors and dielectrics, the Casimir effect manifests itself as a force between such objects.

Any medium supporting oscillations has an analogue of the Casimir effect. For example, beads on a string as well as plates submerged in turbulent water or gas illustrate the Casimir force.

In modern theoretical physics, the Casimir effect plays an important role in the chiral bag model of the nucleon; in applied physics it is significant in some aspects of emerging microtechnologies and nanotechnologies.

Carolyn Jean Spellmann Shoemaker (June 24, 1929 – August 13, 2021) was an American astronomer and a co-discoverer of Comet Shoemaker–Levy 9. She once held the record for most comets discovered by an individual.

Although Shoemaker earned degrees in history, political science and English literature, she had little interest in science until she met and married geologist Eugene M. ("Gene") Shoemaker in 1950–51. She later said that his explanations of his work thrilled her. Despite her relative inexperience and lack of a science degree, California Institute of Technology (Caltech) had no objection to her joining Gene's team there as a research assistant. She had already shown herself to be unusually patient, and demonstrated exceptional stereoscopic vision, which were particularly valuable qualities for looking for objects in near-Earth space.

🔗 Occupational Safety and Health

ISO 7010 is an International Organization for Standardization technical standard for graphical hazard symbols on hazard and safety signs, including those indicating emergency exits. It uses colours and principles set out in ISO 3864 for these symbols, and is intended to provide "safety information that relies as little as possible on the use of words to achieve understanding." It is distinct from the Globally Harmonized System of Classification and Labelling of Chemicals specified by the United Nations to standardise hazardous material classification and labelling.

As of August 2019, the latest version is ISO 7010:2019. This revision incorporates all previous corrigenda, as well as incorporates water safety signs and beach safety flags previously specified in (the now-withdrawn) ISO 20712.

🔗 History 🔗 Visual arts

The Hockney–Falco thesis is a theory of art history, advanced by artist David Hockney and physicist Charles M. Falco. Both claimed that advances in realism and accuracy in the history of Western art since the Renaissance were primarily the result of optical instruments such as the camera obscura, camera lucida, and curved mirrors, rather than solely due to the development of artistic technique and skill. Nineteenth-century artists' use of photography had been well documented. In a 2001 book, Secret Knowledge: Rediscovering the Lost Techniques of the Old Masters, Hockney analyzed the work of the Old Masters and argued that the level of accuracy represented in their work is impossible to create by "eyeballing it". Since then, Hockney and Falco have produced a number of publications on positive evidence of the use of optical aids, and the historical plausibility of such methods. The hypothesis led to a variety of conferences and heated discussions.
