Summary: What is a Scalar Field?

Scalar Fields

One of the more difficult concepts we encounter in physics is the notion of a field. However it is an extremely useful concept. A scalar field is a map over some space of scalar values. That is it is a map of values with no direction. A simple example of a scalar field is a map of the temperature distribution in a room. In this course the most important example is the electromagnetic potential field. Below are a few examples of graphical representations of one particular scalar field.

Definition of a lens

Lenses

A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual Connexions member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
