answer with the information that was available, and broke the sciences into smaller disciplines in the physical and biological realms.

Today, after 200 years of studying those more specific disciplines, many of the most fascinating and important problems lie at the intersection and reintegration of these two realms. And, for the first time, twenty-first-century scientists have the tools and knowledge base to address the large issues that impact the maintenance and quality of life. While this will not be easy, the significant advances in agriculture, energy, medicine, and understanding of climate that appear to be increasingly likely by such intersectional work are required to sustain not only our way of life but also its very existence.
