I am just watching a video on knot theory. in the begining of the video it is stated that: "Of course we now know that atoms are not knonts."
Which raises a question in my head: How do we know, that atoms are not knots?
We clearly do know that atoms are not knots because they are made out of even smaler particles. But how do we know for sure, that these smaler particles are not made out of knots?
