KNOTS
You’ve got a piece of rope – what possible use could it be? Well, you could use it to make a trip wire across a door, as a possible escape route out of an upstairs window, to attach your supplies to the back of your giraffe or just coil it up and wear it as a hat. The uses for rope are endless, but all of those applications will be less than successful if you don’t know how to tie a decent knot.
Over the centuries people bored with stamp collecting have gone in for the far more thrilling study of knots, learning about both their practical and mathematical attributes. Now, we’re not particularly bothered about the mathematical properties of the simple knot (it is unlikely that you will find much use for the equation J = N – 2 during a zombie apocalypse), but discovering the practical applications and learning to tie strong and effective knots that will hold under pressure could be the difference between you comfortably abseiling to safety down the side of a building or ending up as a mushy paste on the pavement below.
