Description:
The latest volume in The New York Times bestselling physics series explains Einstein's masterpiece- the general theory of relativity
He taught us classical mechanics, quantum mechanics and special relativity. Now, physicist Leonard Susskind, assisted by a new collaborator, Andre Cabannes, returns to tackle Einstein's general theory of relativity. Starting from the equivalence principle and covering the necessary mathematics of Riemannian spaces and tensor calculus, Susskind and Cabannes explain the link between gravity and geometry. They delve into black holes, establish Einstein field equations and solve them to describe gravity waves. The authors provide vivid explanations that, to borrow a phrase from Einstein himself, are as simple as possible (but no simpler).
An approachable yet rigorous introduction to one of the most important topics in physics, General Relativity is a must-read for anyone who wants a deeper knowledge of the universe's real structure.

Holds up to chewing, but squeaker didn't last.
Pattern Name: Pumpkin, Size: Large
This pumpkin dog toy for aggressive chewers has held up to the chewing, but the squeaker, which they boasted as indestructible didn't hold up. It lasted maybe 12 hours and now it no longer squeaks which takes away a lot of the fun for my dog.

Bully breed has not destroyed the toy yet
Pattern Name: Apple, Size: Large
Ordered this toy for my Doberman and beagle who destroy every toy they are ever given. The green rope on top of the apple toy lasted for about 24 hours, and the squeaker inside the toy lasted for about 3 days. But the overall body of the toy is still in tact and it has been over a month now. The dogs still play with it despite the squeaker not working.
The body of the toy is definitely durable if you have a bully breed. Both my dogs really enjoy it.
Edit: 7 months later and this thing is still going strong. My doby loves it. It is tough as nails. Changed review to 5 stars.
