Trouble with Gravity: Solving the Mystery Beneath Our FeetWhat is gravity? Nobody knows and just about nobody knows that nobody knows. How something so pervasive can also be so mysterious, and how that mystery can be so wholly unrecognized outside the field of physics, is one of the greatest conundrums in modern science.

What is gravity? Nobody knows--and just about nobody knows that nobody knows. How something so pervasive can also be so mysterious, and how that mystery can be so wholly unrecognized outside the field of physics, is one of the greatest conundrums in modern science. But as award-winning author Richard Panek shows in this groundbreaking, mind-bending book, gravity is a cold case that's beginning to heat up. In The Trouble with Gravity, Panek invites the reader to experience this ubiquitous yet elusive force in a breathtakingly new way. Gravity, Panek explains, structures not only our bodies and our physical world, but also our minds and culture. From our very beginnings, humans' conceptions of gravity have been inextricably bound to our understanding of existence itself. As we get closer and closer to solving the riddle of gravity, it is not only physics that is becoming clearer. We are also getting to know ourselves as never before.Binding Type: Paperback

Love.
Color: Pig Balls
My frenchies love these and large enough not to worry about choking. Also the squeaker lasts longer than most of their latex toys so good or bad, I think it’s good.

Puppy Favorite!
Color: Funny Face Balls
Just the right size for a cocker puppy to fit in her mouth (3 mos. old) and squeak. She will do this indefinitely if I let her, lol! Seems to be very satisfying for her. I can only take so much of it but she loves them. Also bounces erratically when you toss it which she loves.

INDESTRUCTIBLE!!
Color: Transparent with tennis ball inside (1-pack)
My dog is a seriously aggressive chewer! He can destroy a full size basketball in about
10 minutes. He has had this ball about 3 months and loves it!! It is still just like new!
I will say it had a very strong chemical smell when it arrived. I ran it through the dishwasher before giving it to him and it came out fine. l

Not worth it
This ball will last about fifteen minutes. There’s definitely a squeak, size is great due to the handle, and dogs will have fun with it…for a short time. Then, it goes in the trash.
