A team of researchers from Western Norway University of Applied Sciences, Riga Technical University and Ben-Gurion University has created a mathematical model that can be used to predict boarding times for airplanes based ...
In sailing, rock climbing, construction, and any activity requiring the securing of ropes, certain knots are known to be stronger than others. Any seasoned sailor knows, for instance, that one type of knot will secure a sheet ...
