A Powerful New 'QR Code' Untangles Math's Knottiest Knots

Their use of “QR Code” is mighty confusing. QR (Quick Response) Codes are something specific that people are familiar with. These don’t share any characteristics apart from being images which represent something else. They’re not even the same colour or shape. Just call them “knot codes” or something.

The knot codes are beautiful but the ones in the article all seem to be repeating patterns, so I wonder if you could take a 30° slice of each one and save space without losing information.

Interesting article. I love it when maths gives us some beautiful visuals too.

this was so confusing at first not going to lie

Love them knots! The sudoku of the universe :)

This is not a new QR code, nor is it powerful. It's worse in every way and is not really even a code.

  Should “QR Code” be capitalized?

  Yes. “QR Code” must always be capitalized: both letters in “QR” and the “C” in “Code.” The registered trademark symbol (®) should follow the term in published materials. Using lowercase, adding an “s,” or other variations does not exempt you from the trademark.
