a point in a graph that can be connected to other points by links

the irreducible pair: a graph is nodes and links. everything else — degree, path, adjacency, centrality — is derived from these two

in the cybergraph, a node is a particle. a neuron is a special node: it authors cyberlinks rather than just receiving them
