Graph Theory: Euler's Konigsberg Bridges
Saw the bridges problem as a graph, a collection of nodes connected by links. Land areas are nodes and the bridges links.
" Graphs and networks have properties, hidden in their construction, that limit or enhance our ability to do things with them... Small changes in the topology, affecting only a few of the nodes or links, can open up hidden doors, allowing new possibilities to emerge"
