🔗 Maryam Mirzakhani
Maryam Mirzakhani (Persian: مریم میرزاخانی, pronounced [mæɾˈjæm miːɾzɑːxɑːˈniː]; 12 May 1977 – 14 July 2017) was an Iranian mathematician and a professor of mathematics at Stanford University. Her research topics included Teichmüller theory, hyperbolic geometry, ergodic theory, and symplectic geometry. In 2005, as a result of her research, she was honored in Popular Science's fourth annual "Brilliant 10" in which she was acknowledged as one of the top 10 young minds who have pushed their fields in innovative directions.
On 13 August 2014, Mirzakhani was honored with the Fields Medal, the most prestigious award in mathematics. Thus, she became both the first, and to date, the only woman and the first Iranian to be honored with the award. The award committee cited her work in "the dynamics and geometry of Riemann surfaces and their moduli spaces".
On 14 July 2017, Mirzakhani died of breast cancer at the age of 40.

🔗 DRAKON – An algorithmic visual programming language
DRAKON is an algorithmic visual programming and modeling language developed within the Buran space project following ergonomic design principles. The language provides a uniform way to represent flowcharts of any complexity that are easy to read and understand.
The DRAKON Editor, which was released in September 2011, is an implementation of the language available in the public domain. It can be used for creating documentation, or for creating visual programs that can be converted to source code in other languages.
Unlike UML's philosophy, DRAKON's language philosophy is based on being augmented if needed, by using a hybrid language, which can be illustrated as "incrustating code snippets from text language used into shape DRAKON requires". This way, DRAKON always remains a simple visual language that can be used as an augmentation for a programmer who is interested in making their own project code easier to support or other long-term needs for example improving the ergonomics of the coding process or to making code easier to review and understand.
The name DRAKON is the Russian acronym for "Дружелюбный Русский Алгоритмический [язык], Который Обеспечивает Наглядность", which translates to "Friendly Russian algorithmic [language] that illustrates (or provides clarity)". The word "наглядность" (pronounced approximately as "naa-glya-dno-st-th") refers to a concept or idea being easy to imagine and understand, and may be translated as "clarity".
The DRAKON language can be used both as a modelling/"markup" language (which is considered a standalone "pure DRAKON" program) and as a programming language (as part of a hybrid language).
Integration of a stricter, "academic", variant of a markup language into programming, such as provided by DRAKON, adds syntactic sugar allowing users of different programming languages to comprehend each other's contributions to the overall project and even provide commentary if needed.

🔗 Hungry Tree
The Hungry Tree is a tree in the grounds of the King's Inns in Dublin, Republic of Ireland. An otherwise unremarkable specimen of the London plane, it has become known for having partially consumed a nearby park bench. It has become a tourist attraction and is frequently photographed. The Hungry Tree was the subject of a campaign by Green Party politician Ciarán Cuffe to ensure its preservation.
🔗 Schaffer–Vega Diversity System
The Schaffer–Vega diversity system (SVDS) was a wireless guitar system developed in 1975–76, engineered and prototyped by Ken Schaffer in New York City, and manufactured by the Vega Corporation, El Monte, California. A handheld microphone version was introduced in 1977.
The system was the first cordless system to be adopted by major rock acts because it solved technical problems common to earlier wireless systems. The reliable sound and freedom of movement it provided paved the way for bands to tour with large multi-level stages in arenas. Schaffer-Vegas were used in the late 1970s and early 1980s by many rock bands such as Pink Floyd (namely guitarist David Gilmour), the Rolling Stones, AC/DC and Kiss.

🔗 State media (owned, operated, or significantly influenced by the government)
State media are typically understood as media outlets that are owned, operated, or significantly influenced by the government. They are sometimes distinguished from public service media, which are designed to serve the public interest, operate independently of government control, and are financed through a combination of public funding, licensing fees, and sometimes advertising. The crucial difference lies in the level of independence from government influence and the commitment to building trust and serving a broad public interest rather than the interests of a specific political party or government agenda.
State media serve as tools for public diplomacy and narrative shaping. These media outlets can broadcast via television, radio, print, and increasingly on social media, to convey government viewpoints to domestic and international audiences. The approach to using state media can vary, focusing on positive narratives, adjusting narratives retroactively, or spreading misinformation through sophisticated social media campaigns.
Public or state media may be financed through different sources, such as direct government funding, a licence fee paid by television viewers, donations, and commercial advertising.

🔗 Andrée's Arctic Balloon Expedition
Andrée's Arctic balloon expedition of 1897 was an effort to reach the North Pole in which all three Swedish expedition members – S. A. Andrée, Knut Frænkel, and Nils Strindberg – perished. Andrée, the first Swedish balloonist, proposed a voyage by hydrogen balloon from Svalbard to either Russia or Canada, which was to pass, with luck, straight over the North Pole on the way. The scheme was received with patriotic enthusiasm in Sweden, a northern nation that had fallen behind in the race for the North Pole.
Andrée ignored many early signs of the dangers associated with his balloon plan. Being able to steer the balloon to some extent was essential for a safe journey, but there was much evidence that the drag-rope steering technique he had invented was ineffective. Worse, the polar balloon Örnen (Eagle) was delivered directly to Svalbard from its manufacturer in Paris without being tested. When measurements showed it to be leaking more than expected, Andrée failed to acknowledge the risk.
After Andrée, Strindberg, and Frænkel lifted off from Svalbard in July 1897, the balloon lost hydrogen quickly and crashed on the pack ice after only two days. The explorers were unhurt but faced a grueling trek back south across the drifting icescape. Inadequately clothed, equipped, and prepared, and shocked by the difficulty of the terrain, they did not make it to safety. As the Arctic winter closed in on them in October, the group ended up exhausted on the deserted Kvitøya (White Island) in Svalbard and died there. For 33 years the fate of the expedition remained one of the unsolved riddles of the Arctic. The chance discovery in 1930 of the expedition's last camp created a media sensation in Sweden, where the dead men had been mourned and idolized.
Andrée's motives and mindset have been the subject of extensive fictional and historical discussion, particularly inspired by his apparent foolhardiness. An early example is Per Olof Sundman's fictionalized bestseller novel of 1967, The Flight of the Eagle, which portrays Andrée as weak and cynical, at the mercy of his sponsors and the media. Modern writers have been generally critical of Andrée.

🔗 Adrian Schoolcraft: Police Officer Forcibly Committed for Reporting Corruption
Adrian Schoolcraft (born 1976) is a former New York City Police Department (NYPD) officer who secretly recorded police conversations from 2008 to 2009. He brought these tapes to NYPD investigators in October 2009 as evidence of corruption and wrongdoing within the department. The tapes were used as evidence of arrest quotas leading to police abuses such as wrongful arrests, and that emphasis on fighting crime sometimes resulted in under-reporting of crimes to artificially deflate CompStat numbers.
After voicing his concerns, Schoolcraft was repeatedly harassed by members of the NYPD and reassigned to a desk job. After he left work early one day, an ESU unit illegally entered his apartment, physically abducted him and forcibly admitted him to a psychiatric facility, where he was held against his will for six days. In 2010, he released the audio recordings to The Village Voice, leading to the reporting of a multi-part series titled The NYPD Tapes. The same year, Schoolcraft filed a lawsuit against Jamaica Hospital and the NYPD. In 2012 The Village Voice reported that a 2010 unpublished report of an internal NYPD investigation found the 81st precinct had evidence of quotas and underreporting. Both of Schoolcraft's claims were settled in 2015, with him receiving $600,000 for the NYPD portion of the lawsuit.
