Note: The readings this week were hard for me to grasp, so I apologize if I didn’t ‘get’ some of the things in the articles. This subject is totally new to me and I still feel like I don’t really ‘get’ it… I look forward to talking about this in class!
Networks: A Talk by Anna Nagurney
This talk is a great introduction to networks and network theory, the different kinds of networks and the application of network theory. At the end, the speaker talks about a new paradigm for the study of networks – Supernetworks.
Background of Networks:
- Pervasive and essential for functioning of societies and economies.
- Networks exist all around us: business, science, social systems, technology, and education and provide the infrastructure for communication, production and transportation.
Examples of Physical Networks:
- Transportation is a good (and big) example of a networks – transportation allows for face-to-face interaction, access to consumer products and food, etc. transportation networks include highway, railroad, and waterways (for freight). Transportation networks work over roads, rails, water, and air.
- Communication Networks – allowing for communication and connection with our communities and international communities. These networks have also changed our lives – personal and professional. Communication took place based on available resources – from smoke signals and pigeons to computers and phones. The earliest forms of the application of network theory is from Roman times dealing with congestion – constraints on what time chariots can come into the city!
- A type of network that isn’t studied as much (maybe not any more, in the face of the Global Warming and oil shortage issues?) are Energy networks. Ms. Nagurney talks about the blackout of 2003 and the problems that caused.
