The movement gained prominence during the Cold War era, particularly in the 1970s and 1980s, as concerns about nuclear safety, environmental impact, and the potential for nuclear warfare grew.
The anti-nuclear movement in Scotland is a social and political movement that opposes the use of nuclear power and nuclear weapons. This movement has its roots in various concerns, including environmental protection, public safety, opposition to military nuclear systems, and ethical considerations regarding nuclear weapons. Key aspects of the anti-nuclear movement in Scotland include: 1. **Opposition to Nuclear Power**: Many people in Scotland have been opposed to nuclear power due to concerns about safety, radioactive waste management, and environmental impacts.
The anti-nuclear movement in Spain emerged in the late 20th century as a response to the potential risks and environmental impacts associated with nuclear energy. This movement gained significant momentum in the 1970s and 1980s, particularly after a series of nuclear accidents around the world, such as the Three Mile Island incident in the United States in 1979 and the Chernobyl disaster in 1986.
Applied mathematicians come from a wide variety of national backgrounds, as the field of applied mathematics is a global discipline. Some countries known for having significant contributions to applied mathematics include: 1. **United States**: Home to many prominent universities and research institutions that focus on applied mathematics and contribute to various fields like finance, engineering, and data science.

Andrei Knyazev is a mathematician known for his contributions to numerical linear algebra, particularly in the areas of iterative methods for solving large-scale systems of linear equations and eigenvalue problems. He has worked on various algorithms and techniques that are used in scientific computing and optimization.
In the context of Wikipedia and other collaborative platforms, a "stub" is a term used to describe a short article or incomplete entry that provides minimal information on a topic. A "Mathematical physics stub" specifically refers to articles that relate to mathematical physics but do not contain enough information to provide a comprehensive overview of the subject. Mathematical physics itself is a field that focuses on the application of mathematical techniques to problems in physics and the formulation of physical theories in mathematically rigorous terms.
"Delisted digital-only games" refers to video games that were available for purchase and download through digital distribution platforms (such as Steam, PlayStation Store, Xbox Live, or the Nintendo eShop) but have since been removed from those platforms and are no longer available for purchase. This delisting can occur for various reasons, including: 1. **Licensing Issues:** The rights to use certain intellectual properties, music, or content may expire or be revoked, leading to a game's removal.
The Rockwell scale is a system for measuring the hardness of materials, typically metals and polymers. It determines hardness based on the depth of penetration of an indenter under a large load compared to the penetration made by a preload. The test is relatively quick and straightforward, making it one of the most widely used hardness testing methods. There are several Rockwell scales, identified by letters (e.g.
The Rouse number is a dimensionless parameter used in the study of sediment transport in fluid flows, particularly in rivers and other aquatic environments. It characterizes the influence of sediment properties and flow conditions on the transport of sediment particles. The Rouse number is defined as the ratio of the sediment settling velocity to the shear velocity of the flow.
As of my last knowledge update in October 2023, "Dijoin" does not refer to a widely recognized concept, product, or service in popular culture, technology, or other fields. It’s possible that it could be a term that has emerged in a specific niche or context after that date, or it might refer to a smaller-scale or localized project or organization.
A Directed Acyclic Graph (DAG) is a type of graph that has the following characteristics: 1. **Directed**: The edges in the graph have a direction, meaning that they point from one vertex (or node) to another. This is often represented with arrows on the edges.
A **strongly connected component** (SCC) is a concept from graph theory, specifically in the study of directed graphs (digraphs). In a directed graph, a strongly connected component is defined as a maximal subgraph in which every pair of vertices is reachable from each other.
Woodall's conjecture is a statement in number theory related to prime numbers. It posits that for every positive integer \( n \), there exists a prime number that can be expressed in the form \( n \cdot 2^n - 1 \). The conjecture is named after mathematician Richard Woodall, who suggested it in the context of prime-generating formulas.
Discontinued Mozilla plug-ins refer to browser extensions or add-ons for Mozilla Firefox that have been deprecated or no longer supported by Mozilla. This can happen for various reasons, including changes in browser technology, security concerns, or shifts in user demand.
Discontinued custom software projects refer to software development initiatives that were started but ultimately abandoned or halted before they could be completed or fully implemented. There are several reasons why a custom software project might be discontinued, including: 1. **Budget Constraints**: The project may have exceeded its budget, or funding may have been reallocated to other priorities. 2. **Changing Business Needs**: Organizations may experience shifts in their business strategy or requirements, rendering the original project irrelevant.
CDisplay is a popular comic book reader application primarily designed for Windows. It allows users to view digital comic books in various formats, including CBR (Comic Book RAR), CBZ (Comic Book ZIP), and others.

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.
