I usually go to the Lycos50 for pop culture info & instead I found a new science history story - The Seashell on the Mountaintop: A Story of Science, Sainthood, and the Humble Genius Who Discovered a New History of the Earth by Alan Cutler. Nicolaus Steno (1638-1686) was the founder of geology and a scientific groundbreaker who was not supressed by the Church. We'll have to get this one.
