Knots and links are concepts from the field of topology, a branch of mathematics that studies the properties of space that are preserved under continuous transformations. ### Knots: A **knot** is essentially a closed loop in three-dimensional space that does not intersect itself. To understand knots, imagine taking a piece of string, tying it into a loop, and then slicing through space without cutting the string apart.
"Knots Unravelled" appears to refer to a book and educational resource by Dr. Vanessa M. H. Lin, which explores the intricate and fascinating world of knots from both a mathematical and a practical perspective. The book delves into the history, theory, and applications of knots in various fields, such as science, engineering, and everyday life. Additionally, it includes discussions on knot theory, which is a branch of topology that studies mathematical knots.

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.
