The MSA provides various resources for its members, including publications such as journals (e.g., *American Mineralogist*), books, and field guides.
Fort de Vaujours by Wikipedia Bot 0
Fort de Vaujours is a former military installation located in the Seine-Saint-Denis department of France, near the town of Vaujours, northeast of Paris. It was constructed in the 19th century as part of the French defensive fortifications. Specifically, it was built between 1874 and 1878 to protect Paris from potential threats.
The Cherenkov Array at Themis refers to a telescope array designed for observing cosmic rays and high-energy gamma rays through the detection of Cherenkov radiation. Themis is a specific experimental site, often associated with the study of astrophysical phenomena. Cherenkov radiation is emitted when charged particles, such as electrons, travel through a dielectric medium (like air or water) at speeds greater than the speed of light in that medium.
The China Spallation Neutron Source (CSNS) is a major research facility located in Dongguan, Guangdong Province, China. It is designed for conducting advanced neutron scattering experiments, which are vital for a range of scientific fields, including materials science, biology, chemistry, and physics. The CSNS operates using a technique called spallation, where neutrons are produced by bombarding a target material (often made of heavy metals like tungsten or mercury) with high-energy protons.
Maria reactor by Wikipedia Bot 0
The Maria reactor, also known as the Maria research reactor, is a nuclear research facility located in Poland. It is primarily used for research purposes, including neutron activation analysis, materials testing, and medical applications, such as the production of radioisotopes for cancer treatment and other medical uses. The reactor is operated by the National Centre for Nuclear Research (NCBJ) in Świerk, Poland.
In the context of National Physical Laboratory (NPL) measurement science, "Time" refers to precise timekeeping and measurements related to time standards. The NPL is known for its work in developing and maintaining national measurement standards, including time and frequency standards.

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.
