Combined into one volume for the first time, the updated and clarified Exercises for the Feynman Lectures on Physics provides comprehensive, hands-on practice in all the most important areas of physics -- from Newtonian mechanics through the theory of relativity and quantum mechanics. A perfect complement to The Feynman Lectures on Physics, these exercises have all been assigned in Caltech's mandatory two-year introductory physics course, either when Richard Feynman was teaching it, or during the nearly two decades that followed when The Feynman Lectures on Physics was used as the textbook. With this modern, easy-to-use volume, students of physics will have a chance to apply what they have learned in the Lectures and to enhance and reinforce the concepts taught by the inimitable Richard Feynman.Shipping Notes

Squeaky ball
Color: Large Set of 4
Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

My puppy’s favorite
Color: Orange
Great quality and built to last. My dog really enjoys playing with it and stays entertained for quite a while. The material is strong yet safe, and the included drawstring bag is a convenient extra for easy storage.
Is colorful and my become my puppy’s favorite.

If you love your dog…don’t buy this.
Color: Orange
We have a nonaggressive English cocker. She opened the ball every time she played with it. And yes, we are closing it as hard as we can. I do not recommend this toy for any dog! This is a dangerous toy for a dog that is not supervised.
