My thanks to Gary Zukav, author of The Dancing Wu Li Masters, which gave me a new understanding of quantum physics and the nature of what we call “reality.” Thanks also to Frederick E. Wang, co-inventor of Nitinol, who sent me a sample of Nitinol wire and answered several questions I had about this material. And on a personal note, many thanks to Madelyn, Norman and Paul Gilbreath, who read this book and gave me hope that others might be interested; to Linda Nudel and Jan Merlin for encouraging me to pursue the idea of publishing this book; and to my husband, Neil, and my son, Brian, who put up with my preoccupation with completing and publishing this novel.
