Physical Interpretation
The Dirac theory, while providing a wealth of information that is accurately confirmed by experiments, nevertheless introduces a new physical paradigm that appears at first difficult to interpret and even paradoxical. Some of these issues of interpretation must be regarded as open questions. Here we will see how the Dirac theory brilliantly answered some of the outstanding issues in physics at the time it was put forward, while posing others that are still the subject of debate.

Famous quotes containing the word physical:
“When we say that pleasure is the end, we do not mean the pleasure of the profligate or that which depends on physical enjoyment—as some think who do not understand our teachings, disagree with them, or give them an evil interpretation—but by pleasure we mean the state wherein the body is free from pain and the mind from anxiety.”
—Epicurus (c. 341–271 B.C.)
