An Adventure into the Fourth Dimension(CD)

The word dimension indicates a direction (or directions) in space. For instance, we live in a three-dimensional world. Paintings and photographs exist in two dimensions. If there is such a thing as the fourth dimension, it must exist at right angles to our familiar three. And if we postulate the existence of such a dimension, what kind of sensory faculties would be necessary for human consciousness to function within such a framework? Using geometric symbols and analogy, Geoffrey Hodson suggests how we might conceptually approach such a reality. 1967. 24 minutes.
