Edwards examines the influence of celestial motion on the form of plants, embryos, and the heart. His analysis of bud shapes leads him to suggest that all living forms are affected by patterns in time as well as space, with all of life and nature passing through vast cycles of change. He proposes that there are universal laws that guide an organism's growth into predetermined patterns. He gives a detailed account of a complex of phenomena that has hitherto not been observed or described. Edwards's pioneering work with bud shapes has already attracted the attention of many scientists around the world and the implications of his work may lead to a revision of our current scientific worldview.
