A knot polynomial is a mathematical invariant associated with knots and links in the field of knot theory, which is a branch of topology. Knot polynomials are used to distinguish between different knots and to study their properties. Some of the most well-known knot polynomials include: 1. **Alexander Polynomial**: This is one of the earliest knot polynomials, defined for a knot or link as a polynomial in one variable. It provides insights into the topology of the knot and can help distinguish between different knots.
Elizabeth Kujawinski is a prominent oceanographer known for her research in marine chemistry and environmental science. She focuses on understanding the biogeochemical processes in ocean systems and how they relate to climate change and ecosystem health. Her work often involves studying organic matter in the ocean and its implications for carbon cycling and marine life.
Neville's algorithm is a numerical method used for polynomial interpolation that allows you to compute the value of a polynomial at a specific point based on known values at various points. It is particularly useful because it enables the construction of the interpolating polynomial incrementally, offering a systematic way to refine the approximation as new points are added. The basic idea behind Neville's algorithm is to build a table of divided differences that represent the polynomial interpolation step-by-step.
The Polynomial Wigner–Ville Distribution (PWVD) is an extension of the classical Wigner–Ville distribution (WVD), a time-frequency representation used in signal processing. The WVD offers a method to analyze the energy distribution of a signal over time and frequency, providing insight into its time-varying spectral properties. However, the classical WVD can produce artifacts known as "cross-term interference" when dealing with multi-component signals.
The ring of symmetric functions is a mathematical structure in the field of algebra, particularly in combinatorics and representation theory. It consists of symmetric polynomials, which are polynomials that remain unchanged when any of their variables are permuted. This ring serves as a fundamental object of study due to its rich structure and various applications.
The Theory of Equations is a branch of mathematics that deals with the study of equations and their properties, solutions, and relationships. It primarily focuses on polynomial equations, which are equations in which the unknown variable is raised to a power and combined with constants. Here are some key concepts within the Theory of Equations: 1. **Polynomial Equations**: These are equations of the form \( P(x) = 0 \), where \( P(x) \) is a polynomial.
José Mendes is an accomplished physicist known for his work in statistical physics, complex systems, and networks. He has made significant contributions to understanding phenomena such as phase transitions, dynamics on complex networks, and the interplay between individual behavior and collective dynamics in systems. Mendes has published numerous papers in prominent scientific journals and has collaborated with various researchers in the field.
In logic and programming, "scope" refers to the region or context within which a particular variable, function, or symbol is accessible and can be referenced. It determines the visibility and lifetime of variables and functions in a given program or logical expression. ### Types of Scope 1. **Lexical Scope**: Also known as static scope, this is determined by the physical structure of the code. In languages with lexical scoping, a function's scope is determined by its location within the source code.
The Van den Berg–Kesten inequality is a result in the field of probability theory, particularly in the study of dependent random variables. It provides a way to compare the probabilities of certain events that are dependent on each other under specific conditions. In a more formal context, the inequality deals with events in a finite set, where these events are allowed to be dependent, and it provides a bound on the probability of the union of these events.
Vitale's random Brunn–Minkowski inequality is a result in the field of geometric probability, particularly in the study of random convex bodies. It generalizes the classical Brunn–Minkowski inequality, which is a fundamental result in the theory of convex sets in Euclidean space, relating the volume of convex bodies to the volumes of their convex combinations.
P-boxes (probability boxes) and probability bounds analysis are powerful tools in the field of uncertainty quantification and risk assessment. They provide a systematic way to characterize and handle uncertainties in various applications, particularly when precise probability distributions are difficult to obtain.
Gambler's ruin is a concept from probability theory and statistics that models a gambling scenario where a gambler continues to gamble until either they lose all their money or reach a predetermined target amount. It is often used to illustrate the principles of random walks and the behavior of stochastic processes. In a typical setup, a gambler starts with a certain amount of capital and bets on a game with a fixed probability of winning or losing.
Projective polyhedra are a class of geometric structures in the field of topology and geometry. More specifically, a projective polyhedron is a polyhedron that has been associated with the projective space, particularly projective 3-space. In topology, projective geometry can be understood as the study of geometric properties that are invariant under projective transformations.
Kauko Armas Nieminen was a Finnish fighter pilot during World War II, known for his significant contributions to the Finnish Air Force. He is often recognized for his combat achievements and skill in aerial warfare. Beyond his military service, he later became involved in aviation and played a role in the development of civil aviation in Finland. His legacy in Finnish aviation and military history remains notable.
The Coriolis effect refers to the apparent deflection of moving objects when they are viewed in a rotating reference frame, such as the Earth. This phenomenon is caused by the rotation of the Earth on its axis. In a rotating system, such as the Earth, objects moving over its surface appear to be deflected from their straight-line paths.
Oriented projective geometry is a branch of projective geometry that considers the additional structure of orientation. In traditional projective geometry, the focus is primarily on the properties of geometric objects that remain invariant under projective transformations, such as lines, points, and their relations. However, projective geometry itself does not inherently distinguish between different orientations of these objects. In oriented projective geometry, an explicit orientation is assigned to points and lines.
"MacGruber" is a comedy character and television series that originated as a recurring sketch on "Saturday Night Live" (SNL) in the late 2000s. The character, played by Will Forte, is a parody of the action hero archetype, particularly inspired by the 1980s television series "MacGyver.
"MacGyver" (2016) is a reboot of the classic 1985 television series of the same name. The 2016 version follows the adventures of Angus "Mac" MacGyver, a resourceful and inventive secret agent who uses his ingenuity and skills in science and engineering to solve problems and escape dangerous situations.
"MacGyver" is a reboot of the classic 1985 television series of the same name. The 2016 series stars Lucas Till as Angus "Mac" MacGyver, a resourceful secret agent who uses his scientific knowledge and inventive skills to solve problems and complete missions without relying on traditional weapons. As of my last knowledge update in October 2023, the series has a total of five seasons, with the fourth season airing in 2019-2020.

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.
