Dancing Links by Wikipedia Bot 0
Dancing Links, often abbreviated as DLX, is an algorithm specifically designed for efficiently solving the exact cover problem. The exact cover problem involves selecting subsets from a collection of sets such that each element in a universal set is covered exactly once by the selected subsets. The algorithm is based on a data structure called "doubly linked lists," which facilitates the quick addition and removal of rows and columns from the sets being considered.
Blumberg theorem by Wikipedia Bot 0
Blumberg's theorem is a result in the field of mathematical analysis, particularly in the area of measure theory. It provides a criterion for a subset of a complete metric space to be measurable. More specifically, the theorem states that in a complete metric space, if a subset is a countable union of closed sets, it is measurable if it is "small" in a certain sense—specifically, if it has a "density" that approaches 1 in certain limits.

The Body-part counting system is primarily associated with certain practices in various cultures and spiritual traditions, particularly in connection with counting or categorizing aspects of human experience in relation to the body. This can involve using body parts as a means to convey and transmit knowledge, communicate philosophies, or represent numerical values in different contexts. One well-known example is the use of fingers to count in everyday life, where each finger represents a number or a unit of measure.
In relational algebra, **projection** is a fundamental operation that allows you to retrieve specific columns from a relational database table. It is used to create a new relation (table) that contains only the specified attributes (columns) from the original relation, effectively filtering out the unwanted ones. The projection operation is denoted by the symbol π (the Greek letter pi).
Boiling-point elevation is a colligative property of solutions that describes the phenomenon where the boiling point of a solvent increases when a non-volatile solute is dissolved in it. This occurs because the presence of solute particles interferes with the ability of solvent molecules to escape into the vapor phase, which is necessary for boiling to occur.
Bolivian physicists are individuals from Bolivia who specialize in the field of physics, which is the branch of science that studies matter, energy, and the fundamental forces of nature. Like physicists in other countries, Bolivian physicists may work in various subfields, including theoretical physics, experimental physics, condensed matter physics, astrophysics, and more. Many Bolivian physicists engage in academic research, contribute to scientific publications, teach at universities, and participate in international collaborations.
Bollard pull by Wikipedia Bot 0
Bollard pull is a measure of the pulling power of a vessel, particularly tugs and other types of workboats. It is defined as the maximum force that a boat can exert while pulling on a fixed object, typically measured in tons or kilonewtons. The test for bollard pull is usually conducted while the vessel is stationary and tied to a fixed bollard or mooring point.
Crystalline cohomology is a cohomology theory in algebraic geometry and arithmetic geometry that is particularly useful for studying schemes over fields of characteristic \( p \). Developed primarily by Pierre Deligne in the 1970s, it is related to several important concepts in both algebraic geometry and number theory.

Projective range by Wikipedia Bot 0
In mathematics, particularly in the context of functional analysis and projective geometry, the term "projective range" may not have a singular, universally accepted definition, as it can vary depending on the specific field of study or context. However, it generally refers to concepts related to how certain sets or functions can be represented or visualized in a projective space.
Boolean data type by Wikipedia Bot 0
The Boolean data type is a fundamental data type used in computer science and programming that represents one of two possible values: `true` or `false`. It is named after the mathematician George Boole, who developed Boolean algebra, a branch of mathematics that deals with truth values. In programming, the Boolean type is typically used for: 1. **Conditional Statements**: It allows for decisions to be made based on conditions.
The Boolean model of information retrieval is a foundational approach to organizing and retrieving information based on Boolean logic, which uses operators such as AND, OR, and NOT to combine search terms. Developed in the mid-20th century, this model was one of the first methods used in databases and search engines to fetch documents based on user queries. ### Key Features: 1. **Boolean Operators**: - **AND**: Connects two or more terms and retrieves documents that contain all the specified terms.
The Projector Augmented Wave (PAW) method is a computational technique used in quantum mechanics and condensed matter physics for simulating the electronic structure of materials. It is particularly effective for calculating properties of solids and molecules within the framework of Density Functional Theory (DFT).
Tanaka's formula by Wikipedia Bot 0
Tanaka's formula is a result in stochastic calculus that provides a way to express the solution of a stochastic differential equation (SDE) in terms of the Itô integral and the quadratic variation of a continuous local martingale. The formula is particularly significant because it allows for the computation of expectations involving the stochastic processes that satisfy certain SDEs.
The Boolean Prime Ideal Theorem (BPIT) is a statement in set theory and mathematical logic, specifically related to Boolean algebras and topology. It asserts that every Boolean algebra has a prime ideal. This theorem is significant in various areas of mathematics, including model theory and homological algebra. To unpack the notion further: 1. **Boolean Algebra**: A Boolean algebra is a mathematical structure that captures the essence of logical operations like AND, OR, and NOT.
The Boolean Pythagorean triples problem is a mathematical question that involves the search for sets of integers that satisfy a specific condition related to the Pythagorean theorem, with an additional constraint concerning the use of boolean values (0 and 1).

Pinned article: ourbigbook/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.
