My new trick is identical to that of James!
I can see that James trick is identical to mine s with the 3-bights ( and, perhaps, similar to Ashley s #1037...), but I can not see that your trick is identical to James !
And no one of them is identical to the trick presented at Reply#13 :
http://igkt.net/sm/index.php?topic=4476.msg29203#msg29203 I believe that the way everybody
sees a knot is different, so the way one
ties a knot does not have any relation whatsoever with anybody else s way !
I have seen thousands of fishermen and sailors tying bowlines, and I do not remember one instance I had the impression that any one of them did exactly the same thing I use to do...Perhaps I myself "see" what I do very differently than one who sees me...because the haptic perception one has for a small object he holds by his fingers is interwoven, in his mind, with the optical perception of it, in one jammed whole !
Also, there are minor, perhaps, details in a shape that can attract one s eye and help one s brain memorize the general picture, but will not make any impression whatsoever to anybody else. The two lines that meet each other at a right angle, right at the centre of the perimeter of the nipping turn, at the third picture of Reply#13, were not placed in this position by chance...
but t can not estimate the mnemonic value, if any, of this detail for other people. Now that I have decided to see and show the two legs of the two bights that way, a tying sequence which follows exactly the same steps, but does not involve this particular detail, would seem very different to me !
Knots, as shapes, may be less simple than we imagine, but
tying those knots is always a much more complex procedure, involving many more parts of our brain, than we can realize ! The coordinated motion of parts of our body that sets in motion parts of other objects, and re-arranges them in space according to a stored mental image, is an extremely complex thing. It is planned and controlled by obscure regions hidden deep inside our brains, from an epoch even before we developed our eyes to become able to see the light of a day, and the "view" of a knot !
