In the context of mathematics, particularly in geometric topology and metric geometry, a CAT(k) space is a type of metric space that satisfies certain curvature conditions, modeled on conditions defined by the CAT(0) and CAT(k) inequalities. The CAT conditions provide a way to generalize geometric notions of curvature to a broader class of spaces than just Riemannian manifolds.

Psamathe is one of the numerous natural satellites of the planet Neptune. It was discovered in 1989 by a team of astronomers using data from the Voyager 2 spacecraft during its flyby of Neptune. Psamathe is classified as a irregular moon, which means it has an orbit that is more distant and eccentric compared to regular moons. It is also one of the outermost known moons of Neptune.
The Anglo-French Conference on Time-keeping at Sea, held in 1913, was an important gathering of experts from Britain and France aimed at addressing issues related to maritime navigation and timekeeping. The conference was primarily concerned with improving methods for determining longitude at sea, which had long been a challenge for sailors and navigators. One of the key topics of discussion was the need for accurate marine chronometers, which are timekeeping devices crucial for identifying a ship's position by means of celestial navigation.

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
