  Undergraduate Lecture Notes in Physics (ULNP) publishes authoritative texts cov-
  ering topics throughout pure and applied physics. Each title in the series is suitable
  as a basis for undergraduate instruction, typically containing practice problems,
  worked examples, chapter summaries, and suggestions for further reading.
  ULNP titles must provide at least one of the following:
  •
  An exceptionally clear and concise treatment of a standard undergraduatesubject.
  •
  A solid undergraduate-level introduction to a graduate, advanced, or non-
