In this very personal memoir by one of the world’s most beloved scientists, Dr. Philip Callahan's life story unfolds along with the development of his unique blend of science, natural philosophy and spirituality. Recounting incidents from his remarkable life and career, Callahan integrates his early scientific theories and overall religious philosophy with his more recent insights regarding low-level natural energies and the nature of space and time and the realm of the miraculous. He focuses on the scientific as well as religious implications of such sacred places as Medjugorje, Lourdes and Le Puy, and discusses in detail his scientific work surrounding the miraculous images of the Shroud of Turin and the Virgin of Guadalupe. Callahan delves into his own spiritual development and considers the ‘physics’ of miraculous events. A fascinating read.
