The Max-flow Min-cut Theorem is a fundamental result in network flow theory, specifically in the context of directed (or undirected) graphs. It provides a deep relationship between two concepts: the maximum amount of flow that can be sent from a source node to a sink node in a flow network and the minimum capacity that, when removed, would disconnect the source from the sink.
The Perfect Graph Theorem is a result in graph theory that characterizes perfect graphs. A graph is considered *perfect* if, for every induced subgraph, the chromatic number (the smallest number of colors needed to color the graph such that no two adjacent vertices share the same color) equals the size of the largest clique (a subset of vertices, all of which are adjacent to each other).
Veblen's theorem is a result in the field of set theory and topology, specifically in the context of the study of properties of certain sets. It primarily deals with the concept of "well-ordering." The theorem states that every set can be well-ordered, meaning that its elements can be arranged in a sequence such that every non-empty subset has a least element.
Cramer's Rule is a mathematical theorem used to solve systems of linear equations with as many equations as unknowns, provided that the system has a unique solution. It is applicable when the coefficient matrix is non-singular (i.e., its determinant is non-zero).
The Principal Axis Theorem, often discussed in the context of linear algebra and quadratic forms, refers to a method of diagonalizing a symmetric matrix. This theorem states that for any real symmetric matrix, there exists an orthogonal matrix \(Q\) such that: \[ Q^T A Q = D \] where \(A\) is the symmetric matrix, \(Q\) is an orthogonal matrix (i.e.

Lynn Margulis (1938–2011) was an American biologist and a prominent figure in the field of evolutionary biology. She is best known for her contributions to the understanding of symbiosis and the endosymbiotic theory, which proposes that certain organelles in eukaryotic cells, such as mitochondria and chloroplasts, originated as free-living bacteria that were engulfed by ancestral eukaryotic cells.
Michael Conrad is a biologist known for his work in the fields of biology and biological sciences. His research contributions may span various areas, but specific details about his work, research interests, and legacy are not widely covered in the popular literature or public domain. Without further context, it's challenging to provide a detailed overview, as there might be multiple individuals with that name in the scientific community.
A term symbol is a notation used in quantum mechanics and atomic physics to describe the state of an electron configuration in an atom. It provides information about the total angular momentum and the multiplicity (number of possible orientations) of the state, which arises from the spin and orbital angular momenta of the electrons.
Sarah Otto is a noted population biologist and professor at the University of British Columbia in Canada. She is known for her work in ecology, evolutionary biology, and genetics. Her research often focuses on the mechanisms of evolution, including speciation and the dynamics of gene flow in natural populations. Additionally, she has made contributions to understanding the effects of environmental change on biodiversity.
Combining rules, often referred to as combination rules, are principles used in various fields such as mathematics, statistics, and logic to determine how multiple elements, conditions, or probabilities can be combined to produce a result. Here are a few contexts in which combining rules might be relevant: 1. **Probability**: In probability theory, combining rules help in calculating the probability of various events occurring together. This includes using the addition rule for disjoint events and the multiplication rule for independent events.
Crystal structure prediction (CSP) is a computational method used to predict the arrangement of atoms in a crystalline solid based on the chemical composition and thermodynamic stability of potential structures. The goal of CSP is to identify the most stable or energetically favorable crystal structure that a compound can adopt under specified conditions.
Gold hexafluoride, with the chemical formula \( \text{AuF}_6 \), is a hypothetical compound of gold and fluorine. As of my last knowledge update in October 2023, it has not been synthesized or isolated in a laboratory setting. In theoretical considerations, it would involve a gold ion in a high oxidation state surrounded by six fluorine atoms.
Alberte Pullman is not widely recognized in popular culture or historical records, and there may not be significant information available under that name. It is possible that it could refer to a lesser-known individual, a character in a specific work of fiction, or a term used in a niche context.

As of October 2021, there's no widely recognized reference to "Christel Marian." It could be a person’s name or could refer to a specific context, product, work of art, or concept that has emerged recently or is more niche.

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.
