This richly detailed 1981 biography captures both the personal life and the scientific career of Isaac Newton, presenting a fully rounded picture of Newton the man, the scientist, the philosopher, the theologian, and the public figure. Professor Westfall treats all aspects of Newton's career, but his account centres on a full description of Newton's achievements in science. Thus the core of the work describes the development of the calculus, the experimentation that altered the direction of the science of optics, and especially the investigations in celestial dynamics that led to the law of universal gravitation.Binding Type: Paperback

Great Toy for Chewers!
Color: Hammer, Size: 7 Inch
This is one of my dog’s favorite toys! He will chew on it for hours. It is durable and takes him a while to make it indistinguishable as a hammer. No smell to it. The rubber bits do come off so I have to check it and make sure he doesn’t eat them.

Good toy
Color: Hammer, Size: 7 Inch
Solid value for the $. The hammer seems particularly good, my bigger dogs like to hold it down by the head. I bought a 2nd.
