Not sure if I posted this in the correct area, but hopefully it will be moved if I haven't done so. I'm here asking you guys if you know any books relevant to writing a paper on the subject of "The Development of Newton's mechanistic Universe - Principia (1687)." It's for a history class, so it's not a mathematical dissection of Principia. I was just assigned this today, but I'm guessing my prof wants a detailed description of pertinent events leading up to, and including, Newton's writing of his treatise on mechanics, Principia. I went to my university's library and snagged some books, but they're mostly biographies. I'm looking for something more focused on the development of his theories on mechanics. Thanks in advance for any help.
