**A TUTORIAL ON NETWORKS AS AN INTRODUCTION TO RELATIONAL
SYSTEMS THEORY**

Fellow, ISCE

**OBJECTIVES: **

1. To define “network” as a way of modeling relations in the real world.

2. To explore different networks and the kinds of real world things they can model.

3. To use network models to illustrate the difference between mechanistic world views and relational world views and to explore the relationships between them.

**INTRODUCTION:**

** **Network theory arose out of an area of mathematics that did not make the list
of mathematical things we need to know in
order to be modelers of the world (scientists). We believe that this is intimately related
to the world-view promoted by reductionist science, since the focal point of network
theory is the relations between things rather than the things themselves. This tutorial is aimed at providing a partial cure
for that situation. We start with some little
known facts about the situation.

**SOME LITTLE KNOWN FACTS ABOUT THE SITUATION:**

** ** 1) Network
theory, based in algebraic topology and graph theory, contains the vector calculus as a
subtopic.

2) Electrical networks and circuits are a part of a much broader class of physical networks which can be used to model the material world.

3) Even electrical networks are based on thermodynamic concepts to a large extent.

4) In the broader class of “physical networks”, chemical reactions play the role that transistors do in the electronic version. This means that electronic networks, such as those in computers, are a special case of a set of material networks which also can compute and do what computers can. Physical networks have “memory” and can manipulate “data”.
