ABSTRACT
The explosion of knowledge about the world and its constitution emanating from physics, chemistry, and the other physical and natural sciences has left us all amazed and breathless. Key us developments in these areas have radically altered our perspectives on our world, our universe, and who we are as part of it. It has, and is having, as a result, a decisive impact on philosophy and theology in the twentieth century—and will continue to do so. Though the general importance of these astoundingly successful discoveries and programs for philosophy and theology cannot be denied, it is often difficult to specify or describe in detail what particular developments in the physical and natural sciences have the most crucial impact and why.
