The azimuthal quantum number, also known as the angular momentum quantum number or orbital quantum number, is denoted by the symbol \( l \). It is one of the four quantum numbers used to describe the quantum state of an electron in an atom. Here's a summary of its key features: 1. **Definition**: The azimuthal quantum number defines the shape of the electron's orbital and is related to the angular momentum of the electron in that orbital.
French anti-nuclear activists are individuals or groups in France who oppose nuclear energy and advocate for its discontinuation or reduction. Their activism is often motivated by concerns related to environmental protection, public health, safety, and the long-term impacts of nuclear waste. France has historically relied heavily on nuclear power for its electricity, leading to a robust debate about the risks and benefits of such energy sources.
"Rain of animals" refers to a rare meteorological phenomenon where animals fall from the sky, often following a rainstorm. This event can include various animals, such as frogs, fish, or birds, and is usually attributed to strong winds or tornadoes that lift the animals from their habitats and then deposit them over a specific area, often far from where they were originally located. Reports of animal rain have occurred throughout history and across different cultures.
The volcanic winter of 536 is a term used to describe a significant climate event that occurred in the mid-6th century, specifically around the year 536 CE. This phenomenon is widely attributed to massive volcanic eruptions, which led to dramatic changes in weather patterns and widespread cooling across parts of the Northern Hemisphere. The leading theory is that a series of volcanic eruptions, likely from one or more volcanoes in the tropics, injected vast amounts of volcanic ash and sulfur dioxide into the atmosphere.
New Zealand anti-nuclear activists are individuals and groups that oppose the presence, testing, and potential use of nuclear weapons and nuclear energy within New Zealand.

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.

  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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
