To my Grandmother June, who giggles at silly things still

Also to Heather and Judy—four cheers for soup,
coffee, laughter, and red ink

My thanks to Professor Dave Wall,
Department of Physics, City College of San Francisco,
for his help with “Pepper's Ghost.”
M. T.

For my three sons, David, Mike, and Ben—you love,
you inspire, and you keep me on my toes!
