Mumford's compactness theorem is a result in algebraic geometry that pertains to the study of families of algebraic curves. Specifically, it provides conditions under which a certain space of algebraic curves can be compactified. The theorem states that the moduli space of stable curves of a given genus \( g \) (the space that parameterizes all algebraic curves of that genus, up to certain equivalences) is compact.
The Prym differential, often associated with Prym varieties in algebraic geometry, is a concept that arises in the study of algebraic curves and their mappings. Specifically, the Prym differential is linked to the framework of differentials on a double cover of a curve.
A Maclaurin spheroid is a specific type of spheroid that arises in the field of gravitational physics and fluid dynamics. It is named after the mathematician Colin Maclaurin, who studied the figure of equilibrium shapes of rotating fluid bodies. In essence, a Maclaurin spheroid is a symmetrical, ellipsoidal shape that can be described as a type of oblate spheroid.
A spheroid is a three-dimensional geometric shape that is similar to a sphere but is slightly flattened or elongated along one or more axes. The most common types of spheroids are: 1. **Prolate Spheroid**: This shape is elongated along one axis, meaning it is longer in one direction than in the others. An example of a prolate spheroid is an American football.
A rhombus is a type of quadrilateral, which means it is a four-sided polygon. It is characterized by having all four sides of equal length. The main properties of a rhombus include: 1. **Equal Side Lengths**: All four sides of a rhombus are of equal length. 2. **Opposite Angles**: The opposite angles of a rhombus are equal.
Jump threading is a technique used primarily in compiler optimization and, more broadly, in programming languages to improve execution efficiency and reduce the number of conditional branches in code. The concept focuses on reordering or restructuring code that involves conditional statements and jump instructions (like `goto`, break, or continue) to create a more linear flow of execution, which can lead to better performance and easier analysis of the program's control flow.
Option–operand separation is a concept in the context of command-line interfaces and programming languages that refers to the practice of clearly distinguishing between options (or flags) and operands (or arguments) when parsing input. This separation helps to improve the readability and maintainability of command-line commands as well as facilitate easier argument handling by both users and the software.
"This Music" can refer to various topics depending on the context. It might be a phrase used to describe a particular song, musical style, or genre.
Forsyth-Edwards Notation (FEN) is a standard notation for describing the state of a chess game. It is used to succinctly represent the position of pieces on the board, the player to move, castling availability, en passant targets, halfmove clock, and fullmove number. FEN is particularly useful for recording positions in chess literature, computer chess applications, and transmitting chess data.
"West Ice" generally refers to a section of sea ice located in the Arctic region, specifically in the western part of the Arctic Ocean. This area can include portions of the Greenland Sea, the Barents Sea, and other adjacent waters. Sea ice is an important part of the Arctic ecosystem and plays a crucial role in regulating the global climate.
The knot is a unit of speed used primarily in maritime and aviation contexts. It is defined as one nautical mile per hour. A nautical mile, in turn, is based on the circumference of the Earth and is equivalent to one minute of latitude, or approximately 1.15078 statute miles (1.852 kilometers). To summarize: - **1 knot = 1 nautical mile per hour** - **1 nautical mile = approximately 1.15078 statute miles = approximately 1.
The Brazilian Journal of Probability and Statistics (BJPS) is an academic journal that focuses on research in the fields of probability and statistics. It publishes original research articles, reviews, and other contributions related to theoretical and applied aspects of these disciplines. The journal serves as a platform for scholars and researchers to disseminate their findings and advancements in statistical methodologies, probabilistic models, and their applications in various fields.
Hamartia is a term derived from Greek tragedy that refers to a tragic flaw or error in judgment that leads to the downfall of a tragic hero. The word itself translates to "missing the mark." In literature, particularly in the context of Aristotle's definition of tragedy, hamartia is often associated with a character's inherent weakness, which could be a character trait, a mistake, or a failure to understand their situation.
Ontopoetics is an interdisciplinary concept that merges "ontology" (the study of being or existence) with "poetics" (the study of artistic expression, particularly in literature and poetics). It explores the ways in which language, art, and aesthetics can shape and inform our understanding of reality and existence. The term has been particularly associated with the work of philosophers and theorists who investigate how artistic and literary practices can extend, challenge, or redefine ontological frameworks.
Frigide Barjot is a French activist and public figure known for her involvement in the opposition to same-sex marriage in France. She gained prominence as the spokesperson for the "Manif pour Tous" movement, which organized large-scale protests against the legalization of same-sex marriage in France in the early 2010s. Barjot is characterized by her provocative and humorous style, using media attention to advance her views on family and traditional marriage.
"Vpered!" (translated as "Forward!") is a literary work by Russian author and playwright Alexander Griboedov. The title might refer to various works or movements, but one prominent association is with the Russian radical movement in the late 19th and early 20th centuries, which aimed at social and political reform.
William McKinley's 1896 presidential campaign was a pivotal moment in American political history, marking a key turning point in issues related to economics, monetary policy, and political realignments. Here are the main aspects of his campaign: ### Context: - The 1890s were marked by economic turmoil, including the Panic of 1893, which led to a severe national depression.
Hysteron proteron is a rhetorical device in which the order of events is reversed, presenting something that should logically come later in a narrative before something that logically comes first. This technique can create a sense of immediacy, emphasize certain actions, or achieve dramatic effect.
Charles Arthur Willard (1934–2016) was an American philosopher known for his work in the fields of communication, epistemology, and the philosophy of language. He was a professor at the University of Massachusetts Amherst and contributed to various areas including argumentation theory and the analysis of discourse. Willard emphasized the role of communication in the construction of knowledge and reality, focusing on how argumentative practices shape our understanding of truth and belief.

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
