The Algebra Project is an educational program founded by mathematician Robert P. Moses in the late 1980s. Its primary goal is to improve mathematics education for underrepresented and disadvantaged students, particularly in urban areas. The program aims to transform the way algebra is taught and learned, with an emphasis on making the subject accessible and relevant to students' lives.
A Computer Algebra System (CAS) is a software program designed to perform symbolic mathematics. Unlike traditional numerical computation software that deals primarily with approximations, a CAS manipulates mathematical expressions in symbolic form, allowing for exact solutions and a range of algebraic manipulations. Some of the core functionalities of a CAS include: 1. **Symbolic Manipulation**: It can perform algebraic operations such as simplification, expansion, factoring, and polynomial division.
Affine representation refers to a mathematical concept often used in various fields, including computer graphics, geometry, and algebra. It provides a way to represent points, lines, and transformations in space while maintaining certain properties of geometric figures, like parallelism and ratios of distances. ### Key Characteristics of Affine Representation: 1. **Affine Space**: An affine space is a geometric structure that generalizes the properties of Euclidean spaces but does not have a fixed origin.
Algebrator is a software program designed to help students learn and understand algebra. It provides step-by-step explanations for solving various algebraic problems, making it a useful tool for both self-study and classroom learning. The program covers topics such as equations, inequalities, polynomials, factoring, functions, and graphing. Algebrator typically includes features like interactive tutorials, practice problems, and quizzes that adapt to the user's skill level.
"Alternativity" is not a widely recognized term in any specific field, so its meaning can vary depending on the context in which it is used. In general, it can be interpreted as the quality of being alternative or offering alternatives. In some contexts, it might refer to alternative lifestyles, choices, or systems that differ from conventional norms. For instance, in discussions about sustainable living, "alternativity" might refer to alternative energy sources, alternative transportation methods, or alternative food systems.
Vectorette PCR is a molecular biology technique used to amplify specific DNA sequences from complex mixtures. It's particularly useful for isolating and amplifying sequences from genomic DNA when working with certain types of samples, such as those where the target sequence is flanked by unknown or non-specific DNA. The technique involves the use of a "vectorette" — a short, known DNA sequence that is ligated to the ends of the target DNA fragments.
Vector fields on spheres refer to mathematical structures that assign a vector to each point on a sphere. More formally, given a sphere (like the surface of a unit sphere in three-dimensional space), a vector field is a continuous function that maps each point on the sphere to a vector in \(\mathbb{R}^3\) (or the tangent space at that point). ### Key Concepts 1.
Vector radiative transfer refers to the study of how electromagnetic radiation, particularly light, interacts with matter in a medium where the properties of the radiation can be described by vectors. This is an extension of the classical radiative transfer theory that typically considers scalar radiative transfer, which is simpler but less accurate in certain situations. In vector radiative transfer, the polarization state of light is taken into account, which is essential when dealing with scattering processes involving particles, atmospheric optics, and remote sensing applications.
A binary decision is a choice made between two distinct options or outcomes. In the context of decision-making, it typically involves evaluating two possibilities where one is chosen over the other. These types of decisions are often represented as "yes/no," "true/false," or "0/1" scenarios. Binary decisions are common in various fields, including mathematics, computer science, and business, and they form the basis of binary logic used in digital circuitry and programming.
A "friendly number" typically refers to a number that is part of a pair or set of numbers with a mutual relationship, where two numbers share a specific mathematical characteristic. The term is most commonly associated with the concept of "friendly pairs" or "friendly numbers" in the context of number theory, particularly in relation to amicable numbers.
The Vehicle Routing Problem (VRP) is a combinatorial optimization problem that aims to determine the most efficient routes for a fleet of vehicles to deliver goods to a set of customers. It is a fundamental problem in logistics and transportation and has applications in various industries, including delivery services, food distribution, and waste collection. The primary objective of the VRP is to minimize certain costs, such as total distance traveled, time taken, or operational expenses while ensuring that all customer demands are met.
Return on Assets (ROA) is a financial metric used to assess a company's efficiency in using its assets to generate earnings. It indicates how well a company is utilizing its assets to produce profit. The formula for calculating ROA is: \[ \text{ROA} = \frac{\text{Net Income}}{\text{Total Assets}} \] Where: - **Net Income** refers to the profit of the company after all expenses, including taxes and interest, have been deducted.
The Piqua Nuclear Generating Station was a proposed nuclear power plant that was intended to be constructed in Piqua, Ohio. However, it was never built. The project faced various challenges and opposition, leading to its eventual cancellation in the 1980s. There were concerns about safety, environmental impact, and the economic feasibility of nuclear power at the time.
Pitch class space is a concept in music theory that refers to the organization of pitch classes into a conceptual space where notes are treated as equivalent if they are related by octave. In this context, a pitch class is a set of all pitches that are a whole number of octaves apart. For example, the pitch classes C, C#, D, D#, etc., are all represented in their respective "space.
Vertical resistance refers to the resistance that is encountered when an electric field is applied in a direction that is perpendicular (or vertical) to the surface of a material. This term is often used in the context of various types of materials, particularly in the fields of electronics, materials science, and geotechnical engineering. In the context of electrical engineering, vertical resistance can be significant in measuring the performance and behavior of semiconductor devices, capacitors, and other components when subjected to an electric field.
Victor Allis is a notable figure in the field of computer science, particularly known for his contributions to artificial intelligence and game theory. He is best recognized for his work on game-playing algorithms and for creating the game "Gomoku" (also known as Five in a Row) as well as other games in this genre. Allis has also published research on the complexities of games, exploring concepts such as search algorithms and decision-making processes in AI.
"Werk 80 II" is an album by the German heavy metal band Atrocity, released in 1999. It is a continuation of their earlier album "Werk 80," which consisted of covers of various songs from the 1980s, reinterpreted in the band's signature style. "Werk 80 II" follows this concept, featuring new renditions of popular tracks from that era, blending metal and gothic elements with the original songs.
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.

Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
