Viehland–Mason theory is a framework in the field of mathematics, specifically in the study of dynamical systems and their applications to various areas, including control theory and physics. It is well-known in the context of phase space analysis and the examination of stability, bifurcations, and chaos in nonlinear systems. The theory typically involves the use of mathematical tools such as differential equations, topology, and numerical simulations to analyze the behavior of systems over time.
Wet-bulb temperature is a measure of the lowest temperature that can be reached by evaporating water into the air at a constant pressure. It is defined as the temperature indicated by a thermometer when the bulb of the thermometer is moistened with water and exposed to airflow. This thermometer reads lower than the dry-bulb temperature (the air temperature measured by a regular thermometer) when the air is not fully saturated with moisture because of the cooling effect of the evaporation of water.
CygnusEd is an educational platform or edtech solution aimed at supporting learning and teaching processes. It may offer various features, such as online courses, resources for educators, tools for student engagement, and assessments. However, the specific details about CygnusEd can vary widely depending on the context in which it's being used, such as the particular services or features it provides.
The Shiny Trinket Maneuver is not a recognized term or concept in established fields like medicine, science, or psychology as of my last knowledge update in October 2023. It's possible that the term could be a colloquial phrase, a niche reference, or something that emerged after my last update.
"The Big Bang Theory" Season 8 is the eighth installment of the popular American sitcom created by Chuck Lorre and Bill Prady. It originally aired on CBS from September 22, 2014, to May 14, 2015. The season consists of 24 episodes and continues to follow the lives of physicists Leonard Hofstadter and Sheldon Cooper, along with their friends and fellow scientists, Penny, Howard Wolowitz, and Bernadette Rostenkowski-Wolowitz.
The Fundamental Theorem on Homomorphisms, often referred to in the context of group theory or algebra in general, states that there is a specific relationship between a group, a normal subgroup, and the quotient group formed by the subgroup. In summary, it describes how to relate the structure of a group to its quotient by a normal subgroup.
The Barban–Davenport–Halberstam theorem is a result in number theory, specifically in the area of additive number theory and the distribution of prime numbers. It provides a way to estimate the size of the prime numbers in certain ranges. More formally, the theorem deals with the distribution of prime numbers in arithmetic progressions and gives a bound on the number of primes in intervals of certain lengths.
Tverberg's theorem is a result in combinatorial geometry that concerns the division of points in Euclidean space. It states that for any set of \( (r-1)(d+1) + 1 \) points in \( \mathbb{R}^d \), it is possible to partition these points into \( r \) groups such that the \( r \) groups share a common point in their convex hulls.
Theorems about polygons constitute a significant part of geometry, focusing on the properties, relationships, and characteristics of various types of polygons.
Judith Herzfeld is a notable figure in the field of chemistry, particularly recognized for her work in the study of protein folding and the development of techniques in biophysical chemistry. She has contributed to our understanding of molecular interactions and the dynamics of biological macromolecules. Herzfeld is also known for her role in education and mentorship in the scientific community.
As of my last knowledge update in October 2023, Muhammad Imran Qadir does not appear to be a widely recognized public figure. There may be individuals with that name in various fields or regions, but without additional context—such as their profession, notable achievements, or specific area of expertise—it's difficult to provide a precise answer.
Electronic Proceedings in Theoretical Computer Science refers to the online publication of research papers, articles, and other scholarly contributions presented at conferences and workshops within the field of theoretical computer science. These proceedings serve as a medium to disseminate research findings quickly and widely, allowing researchers to access and cite the latest developments in the domain.
Formal methods refer to mathematically-based techniques and tools used for specifying, developing, and verifying software and hardware systems. They emphasize rigorous and precise definitions, providing a framework for ensuring that systems behave correctly and meet their specifications.
As of my last knowledge update in October 2021, Ferran Hurtado does not appear to be a widely recognized figure in public domain contexts such as sports, entertainment, or politics. It's possible that he may be a less prominent individual or that he has gained recognition after my last update.
Peter van Emde Boas is a Dutch computer scientist known for his contributions to the fields of data structures and algorithms. He is particularly recognized for the development of the van Emde Boas tree, a data structure that supports dynamic set operations such as insertion, deletion, and lookup in constant time, or in time that is logarithmic in relation to the universe size.
Bernard Lewis (1916–2018) was a prominent British historian and scholar, primarily known for his work on the history of the Middle East and Islam. He was not a scientist in the traditional sense of the term, but rather an intellectual whose work significantly influenced the fields of history, political science, and Middle Eastern studies.
The number 4000 is a four-digit integer that follows 3999 and precedes 4001. It can represent a quantity, a measurement, or a count of items. In various contexts, it may have different meanings, such as: - In mathematics, it's simply the numeral for the value four thousand. - In currency, it might refer to a specific amount of money (e.g., $4000).
A cubic meter (abbreviated as m³) is a unit of volume in the International System of Units (SI). It is defined as the volume of a cube with each side measuring one meter in length. The cubic meter is commonly used to measure the volume of three-dimensional objects and is a standard unit in various fields, including construction, engineering, and science.
The Minnaert function, or Minnaert profile, is a mathematical model used in the study of planetary atmospheres, particularly in the field of planetary science and astronomy. It describes the variation in brightness of a celestial body as a function of the solar zenith angle, which is the angle between the sun's rays and the normal (perpendicular) to the surface of the body being observed.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
