Strategic nuclear weapons are designed to be used primarily in a large-scale war to deter an adversary from attacking or to destroy significant military and industrial targets. They typically have long ranges and powerful yields, making them capable of causing widespread destruction.
A pumpjack, also known as a beam pump or a nodding donkey, is a mechanical device used to extract crude oil from an oil well. It is commonly used in onshore oil production and is characterized by its distinctive appearance, which resembles a horse's head nodding up and down. The pumpjack operates by converting the rotary motion of an electric or gas-powered motor into the alternating motion required to lift oil from a well.
Stable matching is a concept primarily found in the field of game theory and economics, particularly in the context of matching markets. It refers to a situation where members of two different sets (commonly referred to as "agents") are paired in a way that no two individuals would prefer to be matched with each other over their current partners. This concept was popularized by the Gale-Shapley algorithm, which was introduced in their seminal paper "College Admissions and the Stability of Marriage" in 1962.

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.
