Semiosphere by Wikipedia Bot 0
The term "semiosphere" was coined by the Russian biologist and semiotician Juri Lotman in the context of semiotics, which is the study of signs and symbols and their use or interpretation. The semiosphere refers to the totality of sign systems and the communicative processes that occur within a specific cultural or social context.
Semiotic literary criticism is an approach that applies the principles of semiotics, which is the study of signs and symbols and their use or interpretation, to the analysis of literature. This method focuses on how meaning is constructed and communicated through various signs within a text, including language, imagery, structure, and cultural references.
Semiotic square by Wikipedia Bot 0
The semiotic square is a conceptual tool used in semiotics, a field that studies signs, symbols, and their meanings. Developed by French philosopher and linguist Algirdas Julien Greimas in the 20th century, the semiotic square is used to analyze the relationships between concepts and the way they are structured. The square consists of four corners that represent distinct but related propositions. Typically, it lays out pairs of oppositions and supports the exploration of how meanings are constructed and understood.
The Stone–Weierstrass theorem is a fundamental result in analysis that provides conditions under which a set of functions can approximate continuous functions on a compact space. It generalizes the Weierstrass approximation theorem, which specifically addresses polynomial functions. Here is a more formal statement of the theorem: Let \( X \) be a compact Hausdorff space, and let \( C(X) \) denote the space of continuous real-valued functions on \( X \).
Semiotics of culture is an interdisciplinary approach that applies the principles of semiotics—the study of signs, symbols, and their meanings—to the field of culture. This perspective examines how cultural practices, texts, artifacts, and systems of meaning are constructed and communicated through signs. Key elements include: 1. **Signs and Meaning**: Understanding how signs (words, images, gestures) represent ideas and values within a culture.
Semiotics of music videos involves the study of signs and symbols in the context of music videos and how these elements communicate meaning to viewers. Semiotics, as a field of study, is concerned with how meaning is constructed and understood through signs—anything that carries a meaning, such as images, sounds, and text.
The Sign Relational Complex (SRC) is a theoretical framework that originates from semiotics, the study of signs and symbols and their use or interpretation. The concept often relates to how relationships between different signs create meaning within a particular context or system. In a semiotic framework, signs are typically understood in terms of their three primary components: 1. **Signifier**: The form of the sign, such as a word, image, or sound.
Social semiotics by Wikipedia Bot 0
Social semiotics is a theoretical framework that explores how meaning is constructed and communicated through signs and symbols in social contexts. It extends the study of semiotics, which is the general science of signs and their meanings, by emphasizing the social and cultural dimensions of meaning-making processes. Key aspects of social semiotics include: 1. **Meaning as Social Construct**: Social semiotics posits that meanings are not inherent in signs themselves but are shaped by social practices, cultural contexts, and power dynamics.
Cem Yıldırım by Wikipedia Bot 0
Cem Yıldırım might refer to various individuals, depending on the context, but there is no widely recognized public figure with that exact name as of my last knowledge update in October 2021. It could be a common name in Turkey, and individuals with that name could be involved in various fields, including business, arts, academia, or sports. If you could provide more context or specify the domain (e.g.
A Heronian tetrahedron is a type of tetrahedron (a three-dimensional geometric figure with four triangular faces) whose vertices are all rational points (i.e., points with rational coordinates) and whose face areas are all rational numbers. This means that the lengths of the edges and the areas of the triangular faces can be expressed as rational numbers.
Beal conjecture by Wikipedia Bot 0
Beal's Conjecture is a statement in number theory proposed by Andrew Beal in 1993. It asserts that if \( A^x + B^y = C^z \) holds true for positive integers \( A, B, C, x, y, \) and \( z \) with \( x, y, z > 2 \), then \( A, B, \) and \( C \) must share a common prime factor.
Catalan's conjecture, also known as Mihăilescu's theorem, states that the only solution in positive integers to the equation \( x^a - y^b = 1 \), where \( a \) and \( b \) are integers greater than 1, is the pair \( (3, 2) \) for the values \( (x, y) \) and \( (a, b) = (3, 2) \).
Eisenstein triple by Wikipedia Bot 0
An **Eisenstein triple** is a concept from number theory that refers to a specific type of three-tuple of integers (a, b, c) that satisfies certain conditions related to Eisenstein integers.
Euler's sum of powers conjecture is a proposition made by the mathematician Leonhard Euler in the 18th century. It suggests a relationship between sums of powers of natural numbers and the need for certain numbers to be larger than expected to represent these sums as higher-order powers. The conjecture is specifically about the representation of numbers as sums of n-th powers of integers.
Heegner's lemma by Wikipedia Bot 0
Heegner's lemma is a result in number theory that is primarily concerned with the representation of integers as sums of squares. It plays an important role in the theory of quadratic forms and has implications in the study of class numbers and other aspects of algebraic number theory. Specifically, Heegner's lemma provides a condition under which certain integers can be represented as sums of two squares.
The Prouhet–Tarry–Escott problem is a classic problem in number theory and combinatorial mathematics. It is named after three mathematicians: Pierre Prouhet, Édouard Tarry, and John Escott. The problem can be stated as follows: Given a set of integers, the goal is to find a way to partition these integers into two groups such that the sums of the integers in each group are equal.

A. O. L. Atkin likely refers to a specific name or acronym, but there isn't a widely known figure or concept by that name in public knowledge up to October 2023. If you meant "A. O. L. Atkin" in a particular context—such as a specific field (like literature, science, etc.
Alan Baker is a prominent mathematician known for his contributions to number theory, particularly in the areas of transcendental numbers and Diophantine equations. Born on 19 January 1939, he was awarded the Fields Medal in 1970 for his groundbreaking work in transcendental number theory, specifically for his development of methods to prove the transcendence of certain numbers.

Pinned article: ourbigbook/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!
We have two killer features:
  1. 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-calculus
    Articles 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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
