      'My Favorites' is a special kind of lens which you can use to bookmark modules and collections directly in Connexions. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need a Connexions account to use 'My Favorites'.

      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.

Scalar Field

Module by: Paul Padley

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.
