**Introduction**

A festschrift is "a volume of learned articles, essays, and the like, contributed by colleagues and admirers as a tribute, especially to a scholar." This book is dedicated to Thomas Peyton Armstrong, Professor of Physics and Astronomy at the University of Kansas, on his 50th birthday; it is a special type of tribute: the contributions come exclusively from his former students, who consider themselves fortunate to have learned their craft under his guidance.
