In mathematics, particularly in algebra and number theory, the term "algebraic character" can refer to a notion associated with characters in representation theory and modular forms, or more specifically in the context of algebraic number theory, it may refer to the concept of a character of a Galois group or a local field.
"An Essay on the Application of Mathematical Analysis to the Theories of Electricity and Magnetism" is a significant work by the British mathematician and physicist George Gabriel Stokes, published in 1850. In this essay, Stokes explores the mathematical foundations and principles underlying the theories of electricity and magnetism, providing insights that bridge the gap between mathematical analysis and physical phenomena.
Alice is a scientific instrument designed for use aboard the New Horizons spacecraft, which was launched by NASA to conduct a flyby of Pluto and its moons in 2015. Alice is a ultraviolet (UV) spectrograph, which means it is capable of measuring ultraviolet light across a range of wavelengths. The primary goals of the Alice instrument are to study the composition and structure of the atmospheres of Pluto and its moons, as well as to analyze the surface properties of these celestial bodies.
An alidade is a precision optical instrument used primarily in surveying and navigation to take accurate angular measurements. It typically consists of a sighting device, such as a telescope or a straightedge, mounted on a base or a transit. The instrument allows the user to align the alidade with a distant object, enabling the measurement of the angle relative to a reference line.
As of my last knowledge update in October 2021, there isn't any widely recognized individual or entity by the name of Alida Rossander. It is possible that Alida Rossander could be a private individual, a fictional character, or a name that has gained recognition after that date.
Alison McIntyre may refer to different individuals, depending on the context in which the name is mentioned. One prominent figure is Alison McIntyre, a philosopher known for her work in areas such as epistemology, philosophy of language, and social philosophy. If you are referring to a specific Alison McIntyre or a different field entirely (e.g.
František Wolf could refer to various individuals, but without more context, it is difficult to provide a specific answer.
The Almost Mathieu operator is a significant example of a quasi-periodic Schrödinger operator in mathematical physics and condensed matter theory. It describes a quantum mechanical system in which a particle is subjected to a periodic potential that is modulated by an irrational rotation. Mathematically, the Almost Mathieu operator can be expressed on a Hilbert space of square-summable functions, typically defined on the integers.
The Alpher-Bethe-Gamow paper, formally titled "The Origin of Chemical Elements," is a seminal scientific paper published in 1948 by the physicists George Alpher, Hans Bethe, and Robert Herman. This paper is renowned for its role in the development of the Big Bang nucleosynthesis theory, which describes how the universe's light elements were formed shortly after the Big Bang.
Altai Khairkhan is a mountain range located in Western Mongolia, part of the larger Altai Mountains system. The range is known for its stunning landscapes, including rugged peaks, glaciers, and rich biodiversity. Altai Khairkhan is significant both ecologically and culturally; it is home to various wildlife species and is a site of cultural heritage for local nomadic communities.
An alternating series is a type of infinite series in which the terms alternate in sign. Formally, a series of the form: \[ \sum_{n=0}^{\infty} (-1)^n a_n \] is called an alternating series, where \( a_n \) is a sequence of positive terms (i.e., \( a_n > 0 \)) for all \( n \).
Game accessibility refers to the design and implementation of video games in a way that allows individuals with varying abilities and disabilities to fully experience and enjoy the games. This includes considerations for players with visual, auditory, motor, cognitive, and other disabilities. Key aspects of game accessibility can include: 1. **Visual Accessibility**: Options such as colorblind modes, adjustable text size, and customizable contrast settings help players with visual impairments engage with the game.
In chemistry, "ambident" refers to a specific type of reactive species or functional group that can act as a nucleophile (or electron-pair donor) at more than one site. This term is often used to describe molecules that have two different atoms or groups that can participate in a reaction, particularly in nucleophilic substitution reactions.
An **amenable group** is a type of mathematical structure studied in the field of group theory, specifically in the study of topological groups and functional analysis. The concept of amenability is related to the ability of a group to have a certain type of "invariance" property under averaging processes. A group \( G \) is called **amenable** if it has a left-invariant mean.
The American Association for Public Opinion Research (AAPOR) is a professional organization dedicated to the study and practice of public opinion research. Established in 1947, AAPOR aims to promote the responsible use of survey research and improve the quality of data collection and analysis in the field.
The model year refers to the specific year in which a vehicle model is produced and is typically associated with the year the car is released for sale. In the automotive industry, it serves as a way to distinguish between different versions of the same vehicle, reflecting updates, redesigns, or enhancements made by the manufacturer. For example, a car that is released for sale in late 2023 and labeled as a 2024 model would fall under the 2024 model year.
Populism in Latin America refers to a political approach that seeks to represent the interests and concerns of ordinary people, often contrasted with a perceived elite or establishment. It typically involves charismatic leaders who claim to give voice to the marginalized and disenfranchised populations. The term encompasses a range of ideologies and movements, with variations in its application across different countries and historical contexts.
The American Society for Psychical Research (ASPR) is an organization founded in 1885 that is dedicated to the investigation of paranormal phenomena, including psychical research and the study of topics such as telepathy, clairvoyance, mediumship, and survival after death. The organization aims to explore and understand experiences and phenomena that fall outside the scope of conventional scientific methodologies. The ASPR conducts research, publishes findings, and holds events to promote discussion and analysis of parapsychological experiences.
A gamma-ray spectrometer is an instrument used to measure and analyze gamma radiation emitted by materials. Gamma rays are high-energy electromagnetic radiation that can originate from radioactive decay, nuclear reactions, or cosmic events. The primary purpose of a gamma-ray spectrometer is to detect and quantify gamma rays, often to identify the specific isotopes and their concentrations in a sample.

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.
