This book is based on lectures I gave to various audiences - from schoolchildren to academic societies. It is written in simple language, making it accessible to the widest range of readers. The book contains a lot of material on physics, however, it does not analyze science. As a science teacher and as a youth leader, I have had the opportunity to compare the scientific point of view with the content of the Christian faith. The reader can accept the material as the reflection of a person at the border of natural science and the Christian faith, who in both cases finds answers for himself. Claims arise that there are contradictions between science and religion. And if this book helps eliminate such an opinion, then I believe that it was not written in vain.
