A¹ homotopy theory is a branch of algebraic topology that is concerned with the study of homotopy theories in the context of algebraic varieties over a field, particularly a field with a non-Archimedean valuation or more generally over a base scheme. It is primarily developed in the framework of stable and unstable homotopy types, where the concepts of homotopy can be adapted to the settings of algebraic geometry.
The A. A. Griffith Medal and Prize is an award given by the Institute of Materials, Minerals and Mining (IOM3) in the UK. It is named after the eminent scientist A. A. Griffith, who made significant contributions to the fields of materials science and engineering, particularly in the areas of fracture mechanics and the study of materials' properties.
AAI Aerosonde by Wikipedia Bot 0
The AAI Aerosonde is a type of small unmanned aerial vehicle (UAV) designed primarily for atmospheric research and surveillance purposes. Developed by AAI Corporation, a subsidiary of Textron Systems, the Aerosonde is notable for its ability to operate in a variety of weather conditions and environments, making it suitable for tasks such as meteorological data collection, environmental monitoring, and military reconnaissance.
The internet in Scotland refers to the digital infrastructure and connectivity available within the country, which is part of the United Kingdom. Here are some key points regarding the internet landscape in Scotland: 1. **Infrastructure**: Scotland has a range of internet service providers (ISPs) that offer various types of internet connections, including broadband, fiber-optic, and mobile internet services. Major providers include BT, Virgin Media, Sky, and others.
Abba Mari ben Eligdor was a notable Jewish figure in the medieval period, specifically during the 13th century. He is best known for his contributions to Jewish scholarship and literature. One of his most significant works is the "Sefer ha-Mitzvot," which is a systematic enumeration of the commandments in Jewish law.
The Abbe sine condition is a principle in optical systems, particularly in the design of optical instruments like microscopes and imaging systems. It relates to the alignment of optical components and the criteria for achieving satisfactory resolution and imaging performance.
'Abd al-Hamīd ibn Turk, also known simply as Ibn Turk, was an important figure in the history of Arab and Islamic literature. He lived during the medieval period, and he was known for his contributions to poetry and prose. His works often reflected the cultural and artistic flourishes of his time.
Abd al-Rahman al-Fasi (also known as Abdul Rahman al-Fassi) refers to a prominent figure in Moroccan history, particularly noted for his contributions to Islamic scholarship, political thought, or cultural heritage. While information on specific individuals may vary, the name is often associated with Islamic scholars or leaders from the Fes region of Morocco, a city known for its historical significance in Islamic learning and culture.
Plato's number by Wikipedia Bot 0
Plato's number refers to the number of faces on the Platonic solids, which are the five regular polyhedra that have identical faces of congruent polygons. Specifically, Plato's number is traditionally associated with the number **5**, which corresponds to the five Platonic solids: 1. Tetrahedron (4 faces) 2. Cube (6 faces) 3. Octahedron (8 faces) 4. Dodecahedron (12 faces) 5.
Charlier polynomials are a sequence of orthogonal polynomials that arise in probability and analysis. They are a specific case of hypergeometric polynomials and can be defined in the context of the Poisson distribution. The Charlier polynomials \( C_n(x; a) \) are defined as follows: \[ C_n(x; a) = \sum_{k=0}^{n} \frac{(-1)^{n-k}}{(n-k)!
Planck's law by Wikipedia Bot 0
Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature. Formulated by Max Planck in 1900, it provides a theoretical foundation for understanding black body radiation. The law states that the intensity of radiation emitted at a specific wavelength is proportional to the wavelength and depends on the temperature of the black body.

Abhishek Dhar by Wikipedia Bot 0
As of my last update in October 2023, there is no widely known person or concept specifically referred to as "Abhishek Dhar." It could refer to an individual who may not be a public figure or it might also be a name common in certain regions or communities.
Abortion initiation refers to the process where a pregnancy is intentionally terminated, and "abortive initiation" specifically pertains to the methods and practices used to begin this process. There are several approaches to abortion, including: 1. **Medical Abortion**: Involves the use of medications to induce an abortion. This typically includes a combination of mifepristone (which blocks the hormone progesterone) and misoprostol (which causes the uterus to contract and expel its contents).
Verse paragraph by Wikipedia Bot 0
A verse paragraph typically refers to a section of text in poetry or song lyrics that is arranged in a structured format, often characterized by rhythm, meter, and sometimes rhyme. In contrast to prose, which flows in continuous sentences and paragraphs without specific breaks or structures, a verse paragraph is organized into lines and stanzas. In poetry, a verse paragraph may contain a theme or message and can vary in length.
"Abramowitz and Stegun" commonly refers to the book "Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables," which was edited by Milton Abramowitz and Irene A. Stegun. First published in 1964, this comprehensive reference work has been widely used in mathematics, physics, engineering, and related fields.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
