Shape grammars in computation are a specific class of production systems that generate geometric shapes. Typically, shapes are 2- or 3-dimensional, thus shape grammars are a way to study 2- and 3-dimensional languages. Shape grammars were first introduced in a seminal article by George Stiny and James Gips in 1971. The mathematical and algorithmic foundations of shape grammars (in particular, for linear elements in two-dimensions) were developed in "Pictorial and Formal Aspects of Shapes and Shape Grammars" (Birkhäuser Basel, 1975) by George Stiny. Applications of shape grammars were first considered in "Shape Grammars and their Uses" (Birkhäuser Basel, 1975) by James Gips. These publications also contain two independent, though equivalent, constructions showing that shape grammars can simulate Turing machines.

🔗 Mathematics

A galactic algorithm is one that runs faster than any other algorithm for problems that are sufficiently large, but where "sufficiently large" is so big that the algorithm is never used in practice. Galactic algorithms were so named by Richard Lipton and Ken Regan, as they will never be used on any of the merely terrestrial data sets we find here on Earth.

An example of a galactic algorithm is the fastest known way to multiply two numbers, which is based on a 1729-dimensional Fourier transform. This means it will not reach its stated efficiency until the numbers have at least 2¹⁷²⁹¹² bits (at least 10¹⁰³⁸ digits), which is vastly larger than the number of atoms in the known universe. So this algorithm is never used in practice.

Despite the fact that they will never be used, galactic algorithms may still contribute to computer science:

• An algorithm, even if impractical, may show new techniques that may eventually be used to create practical algorithms.
• Computer sizes may catch up to the crossover point, so that a previously impractical algorithm becomes practical.
• An impractical algorithm can still demonstrate that conjectured bounds can be achieved, or alternatively show that conjectured bounds are wrong. As Lipton says "This alone could be important and often is a great reason for finding such algorithms. For example, if tomorrow there were a discovery that showed there is a factoring algorithm with a huge but provably polynomial time bound, that would change our beliefs about factoring. The algorithm might never be used, but would certainly shape the future research into factoring." Similarly, a ${\displaystyle O\left(n^{2^{100}}\right)}$ algorithm for the Boolean satisfiability problem, although unusable in practice, would settle the P versus NP problem, the most important open problem in computer science and one of the Millennium Prize Problems.

🔗 Gastropods

Costasiella kuroshimae (also known as a leaf slug, sea sheep, or leaf sheep) is a species of sacoglossan sea slug. Costasiella kuroshimae are shell-less marine opisthobranch gastropod mollusks in the family Costasiellidae. Despite being animals, they perform photosynthesis, via kleptoplasty.

Ukraine, formerly a republic of the Union of Soviet Socialist Republics (USSR) from 1922 to 1991, once hosted Soviet nuclear weapons and delivery systems on its territory. The former Soviet Union had its nuclear program expanded to only four of its republics: Belarus, Kazakhstan, Russia, and Ukraine. After its dissolution in 1991, Ukraine inherited about 130 UR-100N intercontinental ballistic missiles (ICBM) with six warheads each, 46 RT-23 Molodets ICBMs with ten warheads apiece, as well as 33 heavy bombers, totaling approximately 1,700 nuclear warheads that remained on Ukrainian territory. Thus Ukraine became the third largest nuclear power in the world (possessing 300 more nuclear warheads than Kazakhstan, 6.5 times less than the United States, and ten times less than Russia) and held about one third of the former Soviet nuclear weapons, delivery system, and significant knowledge of its design and production. While all these weapons were located on Ukrainian territory, initially they were not under Ukraine's control.

In July 1993, the Ukrainian parliament proclaimed ownership of the former Soviet nuclear weapons deployed on its territory. Testimony from the same year by Bruce G. Blair cited the Russian Ministry of Defence’s Chief Directorate for Nuclear Munitions, Colonel General Yevgeniy Maslin, who reportedly stated that Russia had de facto lost control over the nuclear weapons stationed in Ukraine. The same report noted that crews operating strategic nuclear bombers, along with subunits responsible for nuclear munitions, had been incorporated into the Ukrainian Armed Forces, while Moscow still retained operational control over the strategic missile forces at that time. By late 1993, some estimates suggested that Ukraine could break the nuclear release codes between December 1993 and March 1994, as there were no fundamental obstacles preventing it from doing so.

In 1994, Ukraine agreed to transfer these weapons to Russia for dismantlement and became a party to the Treaty on the Non-Proliferation of Nuclear Weapons, in exchange for economic compensation and assurances from Russia, the United States and the United Kingdom to respect Ukrainian independence and sovereignty within its existing borders. Almost twenty years later, Russia, one of the parties to the agreement, invaded Ukraine in 2014 and subsequently also from 2022 onwards.

Hind Rami Iyad Rajab (Arabic: هند رامي إياد رجب; 3 May 2018 – 29 January 2024) was a five-year-old Palestinian girl in the Gaza Strip who was killed by the Israel Defense Forces (IDF) during the Gaza war, which also killed six of her family members and two paramedics coming to her rescue.

Rajab and her family were fleeing Gaza City when their vehicle was shelled by the IDF, killing her uncle, aunt and three cousins, with Rajab and another cousin surviving and contacting the Palestine Red Crescent Society (PRCS) to ask for help while noting that they were being attacked by an Israeli tank. The cousin was later also killed and Rajab was left stranded in the vehicle for hours on the phone, as paramedics from PRCS attempted to rescue her. Both Rajab and the paramedics were later also found dead on 10 February after an Israeli withdrawal.

Israel claimed that there were not any troops present in the neighborhood and denied carrying out the attack. However, this was refuted by The Washington Post and Sky News's investigations relying on satellite imagery and visual evidence, which concluded that a number of Israeli tanks were indeed present and one had likely fired 335 rounds on the car that Rajab and her family had been in, with tank operators being able to see that the car had civilians including children in it. The Forensic Architecture investigation also concluded that an Israeli tank had also likely attacked the ambulance that came for Rajab.

In the aftermath of the killing, Western media outlets were criticized for their coverage of the incident, including for not attributing who killed Rajab and for their adultification of her. American student protestors occupied and renamed Hamilton Hall in her honor at Columbia University, drawing increased attention to the incident.

The Warez scene, often referred to as The Scene, is an underground network of piracy groups specialized in obtaining and illegally releasing digital media before their official release date. The Scene distributes all forms of digital media, including computer games, movies, TV shows, music, and pornography. This network is meant to be hidden from the public, with the files shared only with members of the community. However, as files became commonly leaked outside the community and their popularity grew, some individuals from The Scene began leaking files and uploading them to file-hosts, torrents and EDonkey Networks.

The Scene has no central leadership, location, or other organizational culture. The groups themselves create a rule set for each Scene category (for example, MP3 or TV) that then becomes the active rules for encoding material. These rule sets include a rigid set of requirements that warez groups (shortened as "grps") must follow in releasing and managing material. The groups must follow these rules when uploading material and, if the release has a technical error or breaks a rule, other groups may "nuke" (flag as bad content) the release. Groups are in constant competition to get releases up as fast as possible. First appearing around the time of Bulletin Board Systems (BBSes), The Scene is composed primarily of people dealing with and distributing media content, for which special skills and advanced software are required.

🔗 Visual arts

A Claude glass (or black mirror) is a small mirror, slightly convex in shape, with its surface tinted a dark colour. Bound up like a pocket-book or in a carrying case, Claude glasses were used by artists, travelers and connoisseurs of landscape and landscape painting.

Claude glasses have the effect of reducing and simplifying the colour and tonal range of scenes and scenery to give them a painterly quality. The user would turn their back on the scene to observe the framed view through the tinted mirror — in a sort of pre-photographic lens — which added the picturesque aesthetic of a subtle gradation of tones.
