In a follow up to last week's post about Special Collections' Principia, here are some pictures of the Newton Day tree planting ceremony and our display of rare science books in the Physics Library.
Among the books on display at the event were Isaac Newton's Principia (1687), Johannes Bayer's Uranometria (1655), Galileo Galilei's Dialogo sopra i due massimi sistemi del mondo (1710), Issac Barrow's The Usefulness of Mathematical Learning Explained and Demonstrated (1734).
If you missed your chance to see the Principia in person at the Physics Library, remember that you can view it in the Special Collections Reading Room (provided you bring a government issued photo id or W&M id) or you can see the newly digitized version available in Annotated Books Online.
