The study of knots and links of curves in ordinary 3-dimensional space is an easily visualisable example of topology as ‘flexible geometry’. Knots are divided into various classes, tabulations are produced, yet (as with prime numbers) no real classification seems feasible. Even telling whether two knots are really different can be tricky.
