Andy, it’s been more than a week; if you’ve lost interest, I understand…
>> So I understand, do you only endorse the structure, or both the structure and the motion?
>> For the motion, to product (sic) that structure, my impression is that…
This gives me great insight into your mindset Andy. From the beginning, where you’ve been overly focused on the motion to the exclusion of the structure, I’ve been focused on the structure.
>> Do you think you noticed because at the time you used a similar hand motion to Lee’s, or because the way the ropes crossed just jumped out at you?
Because of the way the ropes crossed jumped out at me! I can spot that Bowline nip no matter how it’s formed.
For now, if you don’t mind, I’d like to focus on the structure. I will be happy to address your fallacious wasted motion theory once we get on the same page with regard to the structure. Ok?
I’ve drawn four figures (see below, and don’t laugh!) as follows:
Figure 1: This is Lee’s loop/nip as achieved after one counterclockwise turn with his right hand. The loop is as it appears in picture Lee #1 that Andy has reproduced several times. Please pay particular attention to the way the lines cross. Notice the label “Down Rope” is as Andy has previously defined. Reproduce this exactly and then rotate the loop 90 degrees in the clockwise direction about the plane of the loop. The result is Figure 2.
Figure 2: Flip the loop about the axis of the line 180 degrees away from you (clockwise with your right hand). The result is Figure 3.
Figure 3: Pay particular attention to the relationship of the crossing lines.
Figure 4: This is Andy #1 that Andy has reproduced several times. Pay particular attention to the relationship of the crossing lines.
Is it now clear that Lee’s loop and Andy’s loop are EXACTLY the same? They are not merely “like” each other.
They are not the same..
…with a different orientation.
…by symmetry.
…due to a reflected image.
…due to opposite hand.
…because “a loop is a loop is a loop.”
They are EXACTLY the same.
>> [From Reply #245]: Looking closely at the two pictures, I see that they do not show the same loop. [Edit to clarify:] On mine, the “down rope” crosses behind. On his, it crosses in front.
Is it clear why one might think they are different since in Andy #1, the “down rope” appears to cross behind and in Lee #1 it appears to cross in front, and that this is simply due to a different vantage point of the exact same loop?
