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.
I mean... There is a 1-1 mapping, and they look kinda like QR codes. so technically, you can make an app that scan it and it will show you the corresponding polynomial.. It could even be useful for fast checking knots
Which I not only mentioned in my comment, it is not even slightly unique to QR codes.
> they look kinda like QR codes
In what way? QR Codes are black and white, square, and asymmetrical. These are colourful, hexagonal, and symmetrical. By that token, a 16th century tile also “looks kinda like a QR Code”.
I very much doubt you could show one of these to someone, ask them what they are, and that they would answer “QR Code”. They don’t look alike at all.

It is strong, but not 1 to 1:

Since they said "the corresponding polynomial", they must mean the mapping between the colored hexagons and the knot polynomials.

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 :)

Yeah this publication needs a legal teamThis is the most non-sensical comment here. That’s not at all how trademarks work.
“Whoa! Some article said this mail app is an ‘Outlook’ for TempleOS! Better call the Microsoft lawyers.”
No, you’re allowed to compare products and ideas and mention their trademarked names without fear of legal issues.
Did the researchers name these “QR codes?”
[dead]
This is not a new QR code, nor is it powerful. It's worse in every way and is not really even a code.
