gave the scientific community time to understand his ideas. Actually, the prize was not given
for the theory of relativity but a somewhat smaller idea upon which the theory was built. If the
Nobel Prize committee could not understand his ideas, what chance do we have!
What does it mean to study communication?
When Andrew teaches this chapter at TCU, his students are early in their course of

explaining to others what it means to study communication, and many admit that they do. To
help them understand how communication differs from other disciplines, Andrew contrasts the

When Glenn teaches this chapter at Purdue, many of his students are also attempting

nature of the major that they are attempting to pursue. A particular source of bewilderment is
the many different areas and activities that make up their Communication department—

One starting place for students is to consider the wealth of theories with which they are
already familiar. Stepping away from the communication discipline, what theories are they
