摘要

Mathematician Leopold Kro necker stated "God created the integers, all else is the work of man," alluding to the fact that the natural numbers most likely arose from physical counting, as in one's fingers or goats in the pasture. Topology, however, is arguably a different creature altogether and may have had its own independent origins from the physical world in the ubiquitous knot-something that cannot be undone without using the free ends because the individual strands cannot move through each other (1).
