The Rhetoric Society of America (RSA) is an organization that promotes the study and teaching of rhetoric in various contexts, including education, communication, and public discourse. Founded in 1977, RSA serves as a professional association for scholars, educators, and practitioners interested in the field of rhetoric. The organization aims to foster research, facilitate communication among scholars, and provide resources and support for rhetorical studies.

The rhetoric of science is a field of study that examines how scientific knowledge is produced, communicated, and interpreted through language and discourse. It explores the persuasive strategies employed by scientists and science communicators to convey their ideas, arguments, and findings to various audiences, including other scientists, policymakers, the media, and the public.

In linguistics, a "scheme" refers to a specific type of linguistic construction or pattern that allows for the systematic variation and organization of elements within a language. Schemes can pertain to various aspects of language, including phonology, syntax, morphology, and semantics. One common context in which the term "scheme" is used is in relation to phonological schemes, which involve patterns of sound distribution and alternation in a language.

"Think of the Children" is a phrase and concept that has been used in various contexts, often in discussions about the impacts of adult decisions on children. It's commonly invoked to argue for caution or responsibility, urging individuals or groups to consider how actions and policies might affect young people.

Thomas Sheridan is an actor known for his work in various television series and films. While specific information about his career may not be extensively documented, he has appeared in notable productions.

Visual rhetoric and composition is an area of study that examines how visual elements—such as images, design, layout, and other graphic components—communicate messages, convey meaning, and influence audiences in written and digital forms. It integrates principles from both visual communication and traditional rhetoric, which focuses on persuasion and argumentation in language. ### Key Components of Visual Rhetoric and Composition: 1. **Visual Elements**: This includes images, colors, typography, diagrams, charts, and multimedia formats.

An Artinian ring is a type of ring in ring theory, which is a branch of abstract algebra. A ring \( R \) is called Artinian if it satisfies the descending chain condition (DCC) on ideals. This means that any descending chain of ideals in \( R \): \[ I_1 \supseteq I_2 \supseteq I_3 \supseteq \ldots \] eventually stabilizes, i.e.

In mathematics, an algebra extension (often referred to as a "field extension" in a specific context) typically involves expanding a given algebraic structure to include additional elements that satisfy certain properties or relationships. 1. **Field Extensions**: In the context of field theory, a field extension is a larger field that contains a smaller field as a subfield.

Clifford algebra is a mathematical structure that extends the concept of vector spaces and inner products into a more generalized algebraic framework. It is named after the mathematician William Kingdon Clifford, who developed the concept in the 19th century. ### Definition A Clifford algebra is generated from a vector space \( V \) equipped with a quadratic form.

Kaplansky's conjectures refer to a set of conjectures proposed by the mathematician David Kaplansky, primarily in the area of ring theory and algebra. One of the most famous is related to the structure of rings, particularly concerning division rings and their fields of fractions. 1. **Kaplansky's Division Ring Conjecture**: This conjecture posits that every division ring that is finitely generated as a module over its center is a field.

Leavitt path algebras are a class of algebras that arise from directed graphs (or quivers) and are named after the mathematician William G. Leavitt, who studied related structures in the context of rings. **Definition:** A Leavitt path algebra is constructed from a directed graph \( E \) and involves both paths in the graph and the concept of vertices and edges.

In ring theory, an element \( a \) of a ring \( R \) is said to be **idempotent** if it satisfies the condition: \[ a^2 = a. \] In other words, when you multiply the element by itself, you get the same element back. Idempotent elements play a significant role in various areas of algebra, particularly in the study of ring structure and module theory.

A Poisson ring is an algebraic structure that combines aspects of both ring theory and Poisson algebra. Specifically, a Poisson ring is a commutative ring \( R \) equipped with a bilinear operation called the Poisson bracket, denoted \(\{ \cdot, \cdot \}\), that satisfies certain properties.

In mathematics, particularly in abstract algebra, the product of rings refers to a construction that combines two or more rings to form a new ring. There are different ways to define the product of rings, but the most common definition is that of the direct product (or Cartesian product) of rings.

In abstract algebra, a **quotient ring** (or factor ring) is a construction that allows you to create a new ring from a given ring by partitioning it into cosets of a subring. More formally, let \( R \) be a ring and \( I \) be a two-sided ideal of \( R \).

The Rosati involution is an important concept in the context of the theory of abelian categories and algebraic geometry, particularly in the study of coherent sheaves and moduli problems. It is a way to define a certain kind of duality between objects in a category, especially in relation to vector bundles on algebraic varieties or coherent sheaves on schemes.

Andrea Branzi is an Italian architect, designer, and theorist, known for his influential work in the fields of architecture and industrial design. Born in 1938 in Florence, Branzi has played a significant role in Italian design culture, particularly as a member of the radical design movement in the 1960s and 1970s.

1:43 scale is a model scale that represents a ratio of 1 unit on the model to 43 units in real life. This means that if an object is 43 inches in real life, it would be approximately 1 inch long in a 1:43 scale model. This scale is commonly used for model cars, trucks, and other vehicles, and it allows for a compact representation of these larger objects while still maintaining a level of detail.

Jorma Panula is a Finnish conductor and music educator known for his work in classical music. Born on March 22, 1930, Panula has had a significant influence on the music scene, particularly in Finland. He has served as a conductor for various orchestras and has been involved in training numerous successful musicians through his teaching. He is also known for his contributions to the study and promotion of Finnish music and has been a mentor to many young conductors.

The Kronos Quartet is a renowned string quartet based in San Francisco, California, founded in 1973 by violinist David Harrington. Known for their innovative and eclectic approach to music, the quartet has gained recognition for its reinterpretation of classical repertoire as well as its commitment to contemporary works. The ensemble has collaborated with a diverse range of composers, including Philip Glass, Terry Riley, Steve Reich, and many others, and has been instrumental in commissioning new works, thereby expanding the string quartet repertoire.
