Fingerprints of Creation Fingerprints is a 33 minute video based on the book Creation's Tiny Mystery. It details the nature of polonium halos and how they provide evidence that the Earth was rapidly formed and did not cool over millions of years. The video, shot mostly in California takes the viewer to picturesque Yosemite National Park during the winter and the regions surrounding Palm Springs and Bishop where granites are plainly visible. Three-dimensional graphic animations are included to help convey the process of halo formation from nuclear particles. Instrumentation similar to that used to gather the published data on the polonium halos is shown along with simple demonstrations which illustrate the basic concepts of a short-lived nuclear emitter. Dr. Gentry explains the history of the origin of granite and scientists' attempts to arrive at a universally accepted model of its formation.
The companion book, Creation's Tiny Mystery, can also be read online in its entirety: http://www.halos.com/book/ctm-toc.htm

Robert Gentry
Dr. Robert V. Gentry is a nuclear physicist who worked 13 years for the Oakridge National Laboratory ('69-'82). He has spent the major part of his scientific career investigating traces of polonium radioactivity inscribed in granite and is arguably the world's leading authority on polonium halos. His research has resulted in authoring or co-authoring over twenty research papers in scientific publications, such as Science, Nature, Geophysical Research Letters, Annual Review of Nuclear Science, and Earth and Planetary Science Letters. When he began his research, he was an evolutionist. Today, Dr. Gentry is a fully convinced young earth creation scientist.
Gentry's work showed that granite was never in a molten condition, because polonium pleochroic halos survive only in solid rock and the half-life of polonium is much too short to survive a multimillion-year cooling time. His results seem to indicate that the Earth was created instantaneously, in a cool condition. If true, it is clear evidence for creation. Gentry documents his evidence in his book, Creation's Tiny Mystery. The book contains copies of Gentry's reports in scientific journals and an intriguing narrative about the scientific community's response to his published findings.
