Ideas that change the world can be few and far between, so it's nice to learn about this fine digital collection from The Huntington Library. Designed to complement the renovated Dibner Hall of the History of Science at the Library, this site peers into the world of astronomy, natural history, medicine, and light. After reading a brief overview about the exhibit, visitors should click on over to the "Learn More" section. This area is truly a treat as users can look at a series of interactive timelines. Using digitized materials from their collection, visitors can learn about the history of astronomy and natural history via key dates, persons of importance, and vital discoveries. Moving on, the "Modern Perspectives" area features videos of scientists and historians talking about the beauty of science in its many combinations and permutations. Finally, the "Digital Book Samples" contains a selection from several important works featured in the collection, such as Englishman Mark Catesby's tome "Natural History of Carolina, Florida, and the Bahama Islands, 1731-1743".
