Issac Newton lived between 1642 and 1727. In the seventeenth century, he tipped the scales of science through his theories of light, motion and most famously, gravity. (Think of the popular story that the idea of gravity came to Newton as he sat under an apple tree). Nonetheless, for all Newton's clarity of scientific vision, his papers, particularly the unpublished ones, have historically been difficult to read and access. This aptly titled 'Windows of Genius' project goes some way to redressing the issue associated with access by making extensive digital content freely available to any site-visitor.
This will be a useful resource for any student of the Enlightenment and those interested in the development of science. Descriptions of the papers and the ability to reproduce the high-resolution images in the Cambridge Digital Library using Creative Commons licensing, also make this a great image-bank for details of Newton's once illegible scrawl.
