A list of mathematical identities consists of equations that hold true for all values of the involved variables, assuming the variables are within the defined domain of the identity. Below, I provide a selection of important mathematical identities across different branches of mathematics: ### Algebraic Identities 1. **Difference of Squares**: \[ a^2 - b^2 = (a - b)(a + b) \] 2.
Lists of integrals typically refer to collections or tables that provide the integrals of various functions, which can be useful for students and mathematicians when solving calculus problems. These lists usually include both definite and indefinite integrals, covering a wide range of functions, including polynomial, trigonometric, exponential, logarithmic, and special functions. The format of a list of integrals will often present the integral alongside its result, often accompanied by conditions related to the variables in the integrals.
Proof mining is a concept in mathematical logic and proof theory that involves the extraction of explicit quantitative information from mathematical proofs, especially those that are non-constructive in nature. The goal of proof mining is to analyze and refine proofs to uncover more concrete or constructive content, such as algorithms, bounds, or explicit data that can be used to solve problems or provide deeper insights into the mathematical structures involved.

He has contributed significantly to the discourse on issues related to election administration and has published various articles and papers in the field.
Modal collapse is a term used in modal logic and philosophy, particularly in discussions of possible worlds and the nature of modality (possibility and necessity). It refers to a situation in which the distinctions between various possible worlds become blurred or meaningless, leading to a kind of reduction or collapse of modal distinctions.
Energy modeling is the process of creating a mathematical representation of energy consumption, generation, and related systems in buildings, industrial processes, or entire cities. These models help in understanding, predicting, and optimizing energy use and can be used for various purposes, including: 1. **Building Design and Performance**: Energy modeling is crucial in the design of energy-efficient buildings. It helps architects and engineers assess energy consumption based on factors like insulation, HVAC systems, lighting, and the overall layout of the building.
The Apparent Infection Rate (AIR) is a measure used to estimate the proportion of individuals within a population that are infected by a particular pathogen or disease, based on observed cases. It is calculated by taking the number of reported or detected cases of infection and dividing it by the total number of individuals tested or surveilled, often expressed as a percentage.
The quasispecies model is a concept in evolutionary biology and virology that describes the dynamics of a population of genetically related organisms, such as viruses, that exist in a state of genetic variability. This model was proposed by the biologist Manfred Eigen in the 1970s and helps explain how populations evolve, particularly under conditions of high mutation rates and selection pressures.

Minion is known for its readability and elegant design, making it a popular choice for both print and digital applications. The typeface comes in a variety of styles and weights, including regular, italic, bold, and small caps, among others.
A Lorentzian manifold is a type of differentiable manifold equipped with a Lorentzian metric. This structure is foundational in the theory of general relativity, as it generalizes the concepts of time and space into a unified framework. Here are the key features of a Lorentzian manifold: 1. **Differentiable Manifold**: A Lorentzian manifold is a differentiable manifold, which means it is a topological space that locally resembles Euclidean space and allows for differential calculus.
Consciousness is a complex and multifaceted concept that refers to the awareness of one's own existence, thoughts, emotions, and surroundings. It encompasses various aspects, including: 1. **Awareness**: The ability to perceive and reflect on one's internal mental states and external environment. This includes sensory perception, thoughts, and feelings. 2. **Self-awareness**: A more advanced form of consciousness where an individual recognizes themselves as an individual, separate from others and the environment.
A spin network is a concept in theoretical physics, specifically in the context of loop quantum gravity, which is a theory attempting to unify general relativity and quantum mechanics. Spin networks represent quantum states of the gravitational field and provide a way to describe the geometry of space at the quantum level.
Traffic flow refers to the movement of vehicles and pedestrians along roadways and intersections. It encompasses various components such as speed, density, and volume of traffic, and is essential for understanding how effectively and efficiently a transportation system operates. Key factors influencing traffic flow include road design, traffic control signals, signage, and driver behavior.
The Wigner quasiprobability distribution is a function used in quantum mechanics that provides a way to represent quantum states in phase space, which is a combination of position and momentum coordinates. It was introduced by the physicist Eugene Wigner in 1932. ### Key Features of the Wigner Quasiprobability Distribution: 1. **Phase Space Representation**: The Wigner distribution allows one to visualize and analyze quantum states similar to how one might analyze classical states.
The Sequential Probability Ratio Test (SPRT) is a statistical method used for hypothesis testing that allows for the continuous monitoring of data as it is collected. It is particularly useful in situations where data is gathered sequentially, and decisions need to be made about hypotheses based on the accumulating evidence. The SPRT was introduced by Abraham Wald in the 1940s.
Herman Wold (1908-2002) was a prominent Swedish economist and statistician, known for his significant contributions to econometrics, particularly in the areas of time series analysis and structural modeling. He is best known for developing techniques related to the estimation of structural models using instrumental variables and for his work in the realm of partial least squares (PLS) regression. Wold's research laid the groundwork for much of the modern approach to model specification, estimation, and validation in econometrics.
Belgian mathematicians have made significant contributions to various fields of mathematics throughout history. Here are a few notable Belgian mathematicians and their contributions: 1. **Georges Lemaitre (1894-1966)**: Astronomer and mathematician, he is best known for formulating the Big Bang theory, which has profound implications in cosmology. He also contributed to the field of units and measures in physics.

"De arte supputandi" is a Latin phrase that translates to "On the Art of Counting" or "On the Art of Calculation." It is often associated with works concerning arithmetic and mathematics, particularly in the context of teaching or explaining methods of numerical computation. One of the notable historical figures connected to this phrase is the 15th-century mathematician Johann Müller, commonly known as Regiomontanus, who wrote on various mathematical subjects, including arithmetic and astronomy.

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.
