A pithy yet deep introduction to Einstein's general theory of relativity
Of the four fundamental forces of nature, gravity might be the least understood and yet the one with which we are most intimate. On Gravity combines depth with accessibility to take us on a compelling tour of Einstein's general theory of relativity. A. Zee begins with the discovery of gravity waves, then explains how gravity can be understood in comparison to other classical field theories, presents the idea of curved spacetime, and explores black holes and Hawking radiation. Zee travels as far as the theory reaches, leaving us with tantalizing hints of the unknown, from the intransigence of quantum gravity to the mysteries of dark matter. Infused with Zee's signature warmth and fresh style, On Gravity opens a unique pathway to comprehending relativity, gravity, spacetime, and the workings of the universe.Binding Type: Paperback

Boxer Baby’s Favorite
Size: Jumbo, Style: Beef
This toy is my sweet girl’s absolute favorite. It was the first thing we gave her when we brought her home, and she has been obsessed with it since. She brings it from room to room, inside and outside. I would highly recommend this toy, however, we have gone through six in one year. They’re not very durable, especially with our boxer mix, who is a very heavy chewer. I’ve gotten the red and the blue, and she will only take red, which is fine with me because the blue STINKS. The red stinks too, but less so. The squeak is very loud, but she genuinely loves it so much that it’s hard to be annoyed by it. I’d say give the toy a try, you may be unintentionally giving them their favorite thing ever lol.

Design Hazard
Size: Medium, Style: Bacon, Size: Medium, Style: Bacon
I have one of these in a larger version I picked up at the petstore. This one I do not recommend. There is a whole in the center where the pet bites down and my doggies' teeth kept getting stuck in it. If you've ever had a toy get stuck in your pups mouth, you've seen how thet go nuts trying to get it out.

Cane Corso approved
Size: Jumbo, Style: Beef
I have two Cane Corsos, One is 80 pounds the other is 120 pounds. They can seriously destroy some toys very easily. These chewies have actually lasted for over six months at this point, which is pretty much miraculous. I bought them some more just so I always had plenty of them laying around as this discourages them from getting into trouble, chewing things they shouldn’t be chewing. They walk around with these and their mouths all the time and even after all these months, the squeakers still work. These are really high-quality and if you have a dog that just destroys toy toy, I highly recommend these. Even though they’ve had these for months, they go back to them to chew on and play with , it’s also really funny because they walk around with one and hanging out of their mouth and it looks like they’ve got a stogie hanging out of their mouth. If these toys can keep the interest and survive being mauled by these two giant Destructo mutts, then they must be really, really tough. I highly recommend these for super chewers. These even a hold up to having one dog, grab each end and then play tug-of-war with it. These guys can Easily go through A cow huff every day, but these toys are still going strong

Not a chew toy
Size: Medium (VALUE 2-Pack), Style: Beef
This is not for a voracious chewer...not durable. My dog destroyed in a matter of minutes, so the cost was high compared to the time it lasted. Maybe my expectation was too high but was disappointed in this product.
