Can Rudolf Steiner's spiritual science shed any meaningful light on one of the most materialistic of human pursuits: research on the atom? Physics teacher Keith Francis believes it can. He traces the concept of the atom from ancient Greece to contemporary quantum physics, all the time relating this compelling quest to relevant statements made by Rudolf Steiner. He concludes that there are, in fact, many connections and parallels between Steiner's thinking and atomic research, and that each illuminates the other in a revealing and inspiring way. This is an ideal book for Steiner-Waldorf teachers looking for a deeper understanding of science.
