The Math & Physics of Knots

Here's a really neat article for all you folks who love getting into the nitty gritty of which knots are better, worse, strong, weak, etc.:

Color Changing Material Unites the Math & Physics of Knots (Quanta Magazine) (~5 minute read)

It's pretty fascinating - the scientists utilize a new material that changes colors based on the tension it’s feeling, allowing them to visualize the forces within different knots.

Thanks for sharing this. It's super cool.

Great find!  And any article that mentions the bastard hogberry deserves even more attention...

The referenced paper in Science is here.  The illustrations are fantastic (e.g., below), but unless you have academic access, you will probably only be able to read the abstract.  However, the article's Supplementary Materials should be available to all; it contains a detailed technical discussion and a couple of movies.

We discussed the article on mp months ago.

Apologies - def didn’t think to search before posting. And it showed up in my newsfeed this week so I blindly assumed it was fresh.

  

For the slow kid in class, what’s the answer?  Which knot is the best?

Which knot is the best?

The one that is appropriate for the application, and you know how to tie correctly.

Grief knot looks easy to use.

It IS fresh...the Science article, linked to above, came out Jan. 3 2020...the guy's wrong.

Eh, check the various pub dates involved 'bro'...

And even if he were correct, what's the problem with having another thread?

Problem is not with the  repost but with some douche-bro not being able to do a simple search and dissing other user for pointing out duplicity of a thread.
