Ramanujan's lost notebook is the manuscript in which the Indian mathematician Srinivasa Ramanujan recorded the mathematical discoveries of the last year (1919–1920) of his life. Its whereabouts were unknown to all but a few mathematicians until it was rediscovered by George Andrews in 1976, in a box of effects of G. N. Watson stored at the Wren Library at Trinity College, Cambridge. The "notebook" is not a book, but consists of loose and unordered sheets of paper described as "more than one hundred pages written on 138 sides in Ramanujan's distinctive handwriting. The sheets contained over six hundred mathematical formulas listed consecutively without proofs."

George Andrews and Bruce C. Berndt (2005, 2009, 2012, 2013, 2018) have published several books in which they give proofs for Ramanujan's formulas included in the notebook. Berndt says of the notebook's discovery: "The discovery of this 'Lost Notebook' caused roughly as much stir in the mathematical world as the discovery of Beethoven’s tenth symphony would cause in the musical world."

Zellige (Arabic: [zˈliʑ]; Arabic: الزليج‎; also zelige or zellij or zileej) is mosaic tilework made from individually chiseled geometric tiles set into a plaster base. This form of Islamic art is one of the main characteristics of Moroccan architecture. It consists of geometrically patterned mosaics, used to ornament walls, ceilings, fountains, floors, pools and tables. The Moroccan traditional patterns and styles are found inside famous buildings such as Al-Qarawiyyin Mosque in Fez, the Alhambra in Granada, Spain, the Great Mosque of Cordoba, the Ben Youssef Madrasa in Marrakech, and the Hassan II mosque in Casablanca, which adds a new color palette with traditional designs.

Just Room Enough Island, also known as Hub Island, is an island located in the Thousand Islands chain, belonging to New York, United States. The island is known for being the smallest inhabited island, which appears to be around 3,300 square feet (310 m²), or about one-thirteenth of an acre. Purchased by the Sizeland family in the 1950s, the island has a house, a tree, shrubs, and a small beach.

Oliver Heaviside FRS (; 18 May 1850 – 3 February 1925) was an English self-taught electrical engineer, mathematician, and physicist who adapted complex numbers to the study of electrical circuits, invented mathematical techniques for the solution of differential equations (equivalent to Laplace transforms), reformulated Maxwell's field equations in terms of electric and magnetic forces and energy flux, and independently co-formulated vector analysis. Although at odds with the scientific establishment for most of his life, Heaviside changed the face of telecommunications, mathematics, and science.

Project 2025 is a plan to reshape the executive branch of the U.S. federal government in the event of a Republican victory in the 2024 U.S. presidential election. Established in 2022, the project seeks to recruit tens of thousands of conservatives to Washington, D.C., to replace existing federal civil service workers it characterizes as the "deep state", to further the objectives of the next Republican president. Although participants in the project cannot promote a specific presidential candidate, many have close ties to Donald Trump and the Trump 2024 presidential campaign. The plan would perform a swift takeover of the entire executive branch under a maximalist version of the unitary executive theory — a theory proposing the president of the United States has absolute power over the executive branch — upon inauguration.

The development of the plan is led by the The Heritage Foundation, an American conservative think tank, in collaboration with over 100 partners including Turning Point USA led by Charlie Kirk; the Conservative Partnership Institute including former Trump Chief of Staff Mark Meadows as senior partner; the Center for Renewing America led by former Trump-appointee Office of Management and Budget Director Russell Vought; and America First Legal led by former Trump Senior Advisor Stephen Miller.

Project 2025 envisions widespread changes across the entire government, particularly with regard to economic and social policy and the role of the federal government and federal agencies. The plan proposes slashing U.S. Department of Justice (DOJ) funding, dismantling the FBI and the Department of Homeland Security, gutting environmental and climate change regulations to favor fossil fuel production, and eliminating the cabinet Departments of Education and Commerce. Citing an anonymous source, The Washington Post reported Project 2025 includes immediately invoking the Insurrection Act of 1807 to deploy the military for domestic law enforcement and directing the DOJ to pursue Trump adversaries. Project Director Paul Dans, a former Trump administration official, said in September 2023 that Project 2025 is "systematically preparing to march into office and bring a new army, aligned, trained, and essentially weaponized conservatives ready to do battle against the deep state."

Project 2025 consists largely of a book of policy recommendations titled Mandate for Leadership: The Conservative Promise and an accompanying personnel database open for submissions. There is also an online course called the Presidential Administration Academy, and a guide to developing transition plans. Reactions to the plan included variously describing it as authoritarian, an attempt by Trump to become a dictator, and a path leading the United States towards autocracy, with several experts in law criticizing it for violating current constitutional laws that would undermine the rule of law and the separation of powers. Additionally, some conservatives and Republicans also criticized the plan, for example in relation to climate change. The Mandate states that "freedom is defined by God, not man."

Han unification is an effort by the authors of Unicode and the Universal Character Set to map multiple character sets of the so-called CJK languages into a single set of unified characters. Han characters are a common feature of written Chinese (hanzi), Japanese (kanji), and Korean (hanja).

Modern Chinese, Japanese and Korean typefaces typically use regional or historical variants of a given Han character. In the formulation of Unicode, an attempt was made to unify these variants by considering them different glyphs representing the same "grapheme", or orthographic unit, hence, "Han unification", with the resulting character repertoire sometimes contracted to Unihan.

Unihan can also refer to the Unihan Database maintained by the Unicode Consortium, which provides information about all of the unified Han characters encoded in the Unicode Standard, including mappings to various national and industry standards, indices into standard dictionaries, encoded variants, pronunciations in various languages, and an English definition. The database is available to the public as text files and via an interactive website. The latter also includes representative glyphs and definitions for compound words drawn from the free Japanese EDICT and Chinese CEDICT dictionary projects (which are provided for convenience and are not a formal part of the Unicode Standard).

Mono no aware (物の哀れ), literally "the pathos of things", and also translated as "an empathy toward things", or "a sensitivity to ephemera", is a Japanese idiom for the awareness of impermanence (無常, mujō), or transience of things, and both a transient gentle sadness (or wistfulness) at their passing as well as a longer, deeper gentle sadness about this state being the reality of life.

Zerah Colburn (September 1, 1804 – March 2, 1840) was a child prodigy of the 19th century who gained fame as a mental calculator.

🔗 Mathematics

A mathematical coincidence is said to occur when two expressions with no direct relationship show a near-equality which has no apparent theoretical explanation.

For example, there is a near-equality close to the round number 1000 between powers of 2 and powers of 10:

${\displaystyle 2^{10}=1024\approx 1000=10^{3}.}$

Some mathematical coincidences are used in engineering when one expression is taken as an approximation of another.

🔗 Philosophy 🔗 Philosophy/Philosophy of mind

The hard problem of consciousness is the problem of explaining why and how sentient organisms have qualia or phenomenal experiences—how and why it is that some internal states are subjective, felt states, such as heat or pain, rather than merely nonsubjective, unfelt states, as in a thermostat or a toaster. The philosopher David Chalmers, who introduced the term "hard problem" of consciousness, contrasts this with the "easy problems" of explaining the ability to discriminate, integrate information, report mental states, focus attention, and so forth. Easy problems are (relatively) easy because all that is required for their solution is to specify a mechanism that can perform the function. That is, regardless of how complex or poorly understood the phenomena of the easy problems may be, they can eventually be understood by relying entirely on standard scientific methodologies. Chalmers claims that the problem of experience is distinct from this set and will "persist even when the performance of all the relevant functions is explained".

The existence of a "hard problem" is controversial. It has been accepted by philosophers of mind such as Joseph Levine, Colin McGinn, and Ned Block and cognitive neuroscientists such as Francisco Varela, Giulio Tononi, and Christof Koch. However, its existence is disputed by philosophers of mind such as Daniel Dennett, Massimo Pigliucci, and Keith Frankish and cognitive neuroscientists such as Stanislas Dehaene and Bernard Baars.
