South African physicists refer to scientists from South Africa who specialize in the field of physics, which is the study of matter, energy, and the fundamental forces of nature. South Africa has a rich history in physics and has produced many notable physicists, both in the past and present, who have contributed significantly to various branches of the discipline, including condensed matter physics, astrophysics, nuclear physics, and theoretical physics.
Grace Alele-Williams was a notable Nigerian mathematician and educator, renowned for her contributions to mathematics education and her role in advancing women's involvement in science and technology in Nigeria. She made history as the first female to earn a doctorate in mathematics in Nigeria, achieving this milestone in 1963. Throughout her career, Alele-Williams served in various academic and administrative roles, including as a professor and Dean of the Faculty of Science at the University of Lagos.
"Amanda Palmer Goes Down Under" is a live album and documentary by the musician Amanda Palmer, released in 2012. It captures her performances and experiences during her tour in Australia and New Zealand. The project showcases not only her music but also her interactions with local fans and the unique cultural aspects of the regions she visited. The album includes a mix of live performances, interviews, and behind-the-scenes footage, providing an intimate look at Palmer's artistic process and her connection with her audience.
The character tables for chemically important 3D point groups provide crucial information about the symmetry properties of molecules and their corresponding vibrational modes. Below is a list of the most common point groups along with their character tables: ### Character Tables for 3D Point Groups 1.
The term "En-ring" isn't widely recognized or defined in mainstream literature or technology as of my last update in October 2023. It could potentially refer to a specific concept in a niche area, a brand name, a project, or perhaps a term that has arisen more recently.
Eliza Edwards can refer to different individuals or subjects, but without additional context, it's not clear which specific "Eliza Edwards" you are inquiring about.
Algebraic representation refers to the use of symbols, variables, and mathematical notation to express and analyze mathematical relationships, structures, and concepts. It allows for the abstract representation of mathematical ideas, such as equations, functions, and operations, in a standardized way. In various contexts, algebraic representation can take different forms, such as: 1. **Algebraic Expressions:** These are combinations of numbers, variables, and operations (like addition, subtraction, multiplication, and division).
In algebra, particularly in the context of systems of linear equations, "augmentation" typically refers to augmenting a matrix. This process involves adding additional columns to a matrix, often to represent augmented matrices which include both the coefficients of the variables and the constants from the equations. For example, if you have a system of linear equations like: 1. \(2x + 3y = 5\) 2.
In the context of Lie theory, a **Borel subalgebra** is a type of subalgebra of a Lie algebra that has certain important properties. Specifically, for a complex semisimple Lie algebra \(\mathfrak{g}\), a Borel subalgebra is a maximal solvable subalgebra.
Chiral algebras are mathematical structures that arise primarily in the context of conformal field theory (CFT) and represent a type of algebra that captures some symmetries and properties of two-dimensional quantum field theories. They are particularly significant in the study of two-dimensional conformal field theories, string theory, and related topics in mathematical physics.
Group theory is a branch of mathematics that studies the algebraic structures known as groups. Below is a list of topics commonly covered in group theory: 1. **Basic Definitions** - Group (definition, binary operation) - Subgroup - Cosets (left and right) - Factor groups (quotient groups) - Order of a group - Order of an element 2.
"Collapsing algebra" is not a formal term commonly found in standard mathematical literature or algebraic studies, so it might refer to a specific concept within a niche area or could involve a misunderstanding or reinterpretation of another algebraic topic. However, if you're inquiring about concepts that involve "collapse," it could relate to topics such as: 1. **Matrix Factorization**: In some contexts, collapsing refers to operations that reduce the dimensions of a matrix.
Graded symmetric algebra is a concept from algebra, particularly in the field of algebraic geometry and commutative algebra. It is a type of algebra that combines elements of symmetric algebra and graded structures.
The Hochster–Roberts theorem is a result in commutative algebra that provides a characterization of when a certain type of ideal is a radical ideal in a ring, specifically in the context of Noetherian rings.
The inflation-restriction exact sequence is an important concept in homological algebra and algebraic topology, particularly in the study of groups and cohomology theories. It relates the cohomology groups of different spaces or algebraic structures through the use of restriction and inflation maps.
Koszul algebra is a concept from the field of algebra, particularly in the area of homological algebra and commutative algebra. It is named after Jean-Pierre Serre, who introduced the notion of Koszul complexes, and it has since been developed further in various contexts. A Koszul algebra is generally defined in connection with a certain type of graded algebra that is associated with a sequence of elements in a ring.

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!
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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
