In the context of Wikipedia, a "stub" refers to an article that is incomplete or lacking in detail and therefore needs expansion. "Applied mathematics stubs" specifically refer to articles related to applied mathematics that have been identified as needing more comprehensive information. Applied mathematics is a branch of mathematics that deals with mathematical methods and techniques that are typically used in practical applications in science, engineering, business, and other fields.
Applied statistics is a branch of statistics that focuses on the practical application of statistical methods and techniques to real-world problems across various fields. Unlike theoretical statistics, which is concerned with the mathematical foundations and principles of statistical methods, applied statistics involves the implementation of statistical tools to analyze data and derive insights in specific contexts.
Arab astronomers refer to scholars and scientists in the Islamic world who made significant contributions to the field of astronomy from the 8th to the 14th centuries. During this period, known as the Islamic Golden Age, scholars in the Arab region, as well as other parts of the Islamic empire, advanced astronomical knowledge by building on Greek, Indian, and Persian works and conducting original research.
Astrophysics is a branch of astronomy focused on understanding the physical properties and underlying mechanisms of celestial bodies and phenomena. It combines principles from physics and astronomy to explain how the universe works. Several key theories in astrophysics help us understand various aspects of the universe, including: 1. **General Relativity**: Proposed by Albert Einstein, this theory explains gravity as a curvature of spacetime caused by mass.
Atmospheric Pressure Photoionization (APPI) is an ionization technique commonly used in mass spectrometry. It is particularly useful for the analysis of a wide range of compounds, including those that are non-polar or semi-polar, which often do not ionize well using traditional techniques like electrospray ionization (ESI) or matrix-assisted laser desorption/ionization (MALDI).
The Gelfond–Schneider constant is a mathematical constant denoted by \( e^{\sqrt{2}} \). It is named after the mathematicians Aleksandr Gelfond and Reinhold Schneider, who proved its transcendental nature.
In mathematics, particularly in the area of additive combinatorics, a sumset is a set formed by the sum of elements from two or more sets.
Superferromagnetism is a phenomenon that refers to a type of magnetic ordering characterized by a special alignment of magnetic moments in materials. In typical ferromagnets, the magnetic moments of neighboring atoms align parallel to each other, leading to a net macroscopic magnetization. However, in superferromagnetic materials, there is a unique situation where a significant population of atoms can align in parallel, resulting in an exceptionally strong magnetization.
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!
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.

Source. - 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.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
