William Schieffelin Claytor (1908–1967) was an American mathematician known for his contributions to topology and particularly for his work in algebraic topology and the study of topological spaces. He is perhaps best known for the Claytor-Whitehead theorem, which relates to the concept of homotopy in algebraic topology. Claytor's work has had an impact on the field, and he is remembered for his academic contributions and mentorship of students.
Hilton's theorem is a result in the field of algebraic topology, specifically concerning the relationships between the homotopy groups of spheres and certain types of function spaces. The theorem is named after the mathematician Paul Hilton. The essence of Hilton's theorem deals with the stable homotopy groups of spheres. More precisely, it states that the stable homotopy groups of spheres can be completely described using the stable homotopy type of the space of pointed maps from a sphere into a sphere.
A **non-Archimedean ordered field** is a type of ordered field that does not satisfy the Archimedean property. To understand what this means, let's break it down.
A constructive proof is a type of mathematical proof that demonstrates the existence of a mathematical object by providing a method to explicitly construct or find that object. In other words, instead of merely showing that something exists without providing a way to create it, a constructive proof offers a concrete example or algorithm to generate the object in question.
The Diamond Principle generally refers to a concept in various fields, particularly in decision-making, economics, and management. While it can be interpreted in different contexts, one common interpretation of the Diamond Principle is related to the theory of competitive advantage in business and economics, often represented by Michael Porter’s "Diamond Model" of national advantage. Here's a brief overview of that concept: ### Michael Porter’s Diamond Model of National Competitive Advantage 1.
Phenomenalism is a philosophical theory concerning the nature of perception and reality. It posits that physical objects do not exist independently of our perception of them, but rather, they can be understood only through the phenomena they present to us. In other words, what we understand as physical objects are collections of sensory experiences or phenomena rather than things that exist in an objective, mind-independent way.
The Axiom Schema of Specification (also known as the Axiom Schema of Separation) is a fundamental principle in set theory, particularly in the context of Zermelo-Fraenkel set theory (ZF). It is one of the axioms that govern how sets can be constructed and manipulated within this framework. In essence, the Axiom Schema of Specification allows for the creation of a new set by specifying a property that its elements must satisfy.
The "Wholeness Axiom" is often associated with the field of mathematics, particularly in discussions around set theory and certain formal systems. It posits that a collection of objects, or a set, is considered whole if it contains all the elements of interest without exceptions or omissions. In a broader philosophical or conceptual framework, the Wholeness Axiom can be interpreted as asserting that a system is complete when it encapsulates all necessary components or properties within it.
Standard translation typically refers to the traditional method of translating text from one language to another, maintaining the original meaning, context, and tone. This approach prioritizes accuracy and fidelity to the source material, ensuring that the intended message is conveyed in the target language while adhering to linguistic and cultural norms. In practice, standard translation involves the following aspects: 1. **Literal Translation**: Directly translating words and phrases while taking into account grammatical differences between languages.
Adam Smith (1723–1790) was a Scottish philosopher and economist who is best known for his influential work in the field of economics and is often referred to as the "father of modern economics." His most notable works include "The Theory of Moral Sentiments" (1759) and "An Inquiry into the Nature and Causes of the Wealth of Nations" (1776).
The term "tolerant sequence" can refer to different concepts depending on the context in which it is used. However, there is no widely recognized mathematical or scientific definition for "tolerant sequence" as a standalone term. In some contexts, it might refer to sequences or lists that can accommodate certain variations or errors without significant impact on their overall meaning or function.
Folklore refers to the collective traditions, customs, beliefs, stories, songs, and practices that are passed down orally within a community or culture. It encompasses various forms of cultural expression, including myths, legends, fairy tales, proverbs, rituals, and traditional music and dance. Folklore plays a crucial role in shaping cultural identity and can provide insights into the values, history, and social norms of a particular group.
Substantial truth refers to a concept in law, especially in the context of defamation, where the truth of a claim is judged not just on technical or trivial details but on the overall essence or substance of the statement. If a statement, despite some inaccuracies, accurately conveys the truth about a person's character or actions, it may be deemed substantially true. In legal terms, if a defendant can demonstrate that a statement is substantially true, they may be able to avoid liability for defamation.
Polysemy refers to a phenomenon in linguistics where a single word or phrase has multiple meanings or interpretations. These meanings are related by extension or metaphor and often share a conceptual link. For example, the word "bank" can refer to the financial institution where one deposits money or the land alongside a river. In both cases, the meanings are linked through a broader concept of a place where something is stored or managed.
Mathematical programming is a branch of applied mathematics that deals with the problem of finding the best solution from a set of feasible solutions. It often involves maximizing or minimizing a particular objective function subject to constraints that define the feasible region. Mathematical programming is widely used in various fields, including economics, engineering, logistics, finance, and operations research.
The Rocky Mountain Journal of Mathematics is a peer-reviewed journal that publishes research articles in various areas of mathematics. Established in 1971, it focuses on high-quality original research, reviews, and expository papers that cover a wide range of mathematical topics, including but not limited to algebra, analysis, geometry, and applied mathematics. The journal aims to promote mathematical research and foster communication among mathematicians, particularly those associated with the Rocky Mountain region, although it is open to authors and readers worldwide.
Topology is a peer-reviewed academic journal that specializes in the field of topology, a branch of mathematics concerned with the properties of space that are preserved under continuous transformations. Established in 1961, the journal publishes research articles that cover various areas of topology, including general topology, algebraic topology, and related aspects of mathematics. The journal serves as a platform for mathematicians to disseminate significant findings, advancements, and theories in topology and its applications.
Friedrich L. Bauer was a prominent German computer scientist known for his contributions to various areas of computer science, particularly in the fields of algorithm design, programming languages, and software engineering. Born on July 2, 1924, he played a significant role in the development of early computing in Germany and worked on several advanced computing topics, including formal methods and programming language theory.
The 1950s marked a significant period in the development of computers. It was a decade characterized by the transition from vacuum tube-based systems to transistor technology, which laid the foundation for modern computing. Here are some key highlights of 1950s computers: 1. **Early Mainframes**: This decade saw the rise of mainframe computers designed for scientific and business applications.

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.
