Comment Not much practical use, yet. (Score 4, Interesting) 74
They've studied how much force it takes to tighten a very simple overhand knot with various numbers of turns and developed mathematical theory that is good at predictions. Whilst it's interesting, most knot use is probably more interested in the opposite case of how much force is necessary to untie a knot, or how much force a knotted rope can withstand, or which knot configurations are comparable in strength. That'll take a much bigger leap in research but this is a good start.
