1. Networks between facts & concepts Marianne van den Boomen

2. Natural networks Cultural networks

3. Nature: physical, organic & neuronal networks

4. Culture: social, technical & media networks

5. Networks may be facts… but also abstract concepts….

6. A network is a set of links/relations between elements/nodes of a unit

7. Networks everywhere

8. Network definition Dots stand for? Lines stand for? Colors stand for? Circles stand for?

9. source: form target: anything target: internet source: highway Networks as metaphors

10. 3 root metaphors for networks 1.Telegraph 2. Nerve system 3. Diagram

11. 1. Telegraph metaphor Telegraph: roads, pipes, wires, channels empty infrastructure for possible traffic homogeneous nodes & connection paths/lines

12. 1. Telegraph metaphor external control by architecture, rules & protocol example: electronic highway

13. 2. Nerve metaphor Nervous system (ecosystem, cells, DNA, brains, life) organic emergence of structure, elements & traffic heterogeneous nodes & connections/relations

14. 2. Nerve metaphor internal control by adaptation, mutual shaping, feedback & (self)organization example: cyberspace

15. 3. Diagram metaphor abstract representation of relations/’links’ maps of nodes & links: visual patterns

16. 3. Diagram metaphor examples: data traffic – Twitter centers – social ties - cell metabolism - movie actors - scientific citations – hyperlinks control: internal, external?

18. Facebook

19. Network: factual or conceptual? Phenomenon: ecosystemModel/metaphor: network diagram

20. Metaphor = theory Model/metaphor Theory Phenomenon

21. Network theory = network politics Theory/model: for example rhizome (or power law, or protocol, or evolution, etc) ‘Phenomenon’: network
