Knot tieing was solved empirically thousands of years ago, spamming
shit head.

The point of the article was to suck up funds, shit for brains spammer.

Nope, the point was obvious; someone had funds to piss away on trivial
nonsense, shit head.

perfect knots transfer all the force from the rope to the fixed point, 
or another rope.

it is not about how much force it takes to pull it  tight.


ropes lose about 50% of strength due to the knot.

Knots work on friction.Add a twist and its more tight.Figure 8 is a very old sailer knot.Sailer gave the word knot to relate with speed of their ship.On water we don;t use MPH.A fast sub can go 40 knots in an hour.You can go much faster on ice sailing. On ice we use MPH   Go figure  TreBert

Herb, knots work on friction and it it friction in the water that 
determines speed. That's why sailors measure speed in knots. That is a 
given.
