Hello I am about to finished working though Spivak's Calculus. I am wondering if you guys could give me some recommendations on what to read after I'm done with the book. I am looking for something as rigorous as Spivak. Also a bit unrelated but I have also worked through an old edition of Calculus by Thomas (before spivak). So I recently bought kleppner and Kolenkow's Mechanics book but I also own a second edition of Halliday and Resnicks Physics for scientists and engineers. I have never formally taken a physics class before and I am wondering which book I should start with. Thank you for taking your time reading my post.
