Relativity: A Very Short IntroductionIf you move at high speed, time slows down, space squashes up and you get heavier.

If you move at high speed, time slows down, space squashes up and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing-and live forever As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over a hundred years since he made these discoveries, and yet the general public is still largely unaware of them. Filled with illuminating anecdotes and fascinating accounts of experiments, this book aims to introduce the interested lay person to the subject of relativity in a way which is accessible and engaging and at the same time scientifically rigorous. With relatively few mathematical equations--nothing more complicated than the Pythagoras's Theorem--this VSI packs a lot time into very little space, and for anyone who has felt intimidated by Einstein's groundbreaking theory, it offers the perfect place to start.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam.

Emotional Support Lizard
Size: 15 Inch
This was my Goldendoodle puppy's first toy, and a year later, it's still his favorite. It was light enough for him to play with it at 9 pounds, but big enough that he still loves it at 40 pounds. He carries it around, slaps his brother with it, throws it and chases it, sleeps with it, etc. He enjoys his stuffies also, but he returns to this one repeatedly through the day, so I know he loves it. It's a bit discolored, but still fully intact. If you have a dog with a soft mouth who isn't prone to chewing, this toy is perfect. I've purchased extras to keep in the emergency supplies in both the house and the car.

Not for puppies or dogs who enjoy chewing toys.
Size: 25 Inch
NOT FOR PUPPIES OR CHEWERS! If you have a dog that is teething or enjoys chewing on toys for soothing this is not the toy to buy. My 4 month old ate the sneak head off and the inside plastic ball squeaker was exposed and fell out and my puppy swallowed it. I tried to take it away from him but it was too late .. he already swallowed it. This caused serious vomiting days later in my pup. I’m not likely to leave negative reviews unless I truly have a horrific experience and this toy provided just that. 0 stars.

Good for kittens & cats too!
Size: 15 Inch
Bought this for our new kitten, 5 months old, and didn't know if it was a good purchase or not. He loves it! He can chew on it, drag it around the house, interact with us too. And he hasn't lost or destroyed it. The only disappointment is the head squeaker stop working. The placard stated it would work even if bit. Not a big deal, though; kitten doesn't like the squeak. LOL

My dog's favorite toy, but
Size: 15 Inch
My dog loves his "lizzie" but the quality has gone down. The leather is thinner and easily torn, exposing the squeaker which becomes a swallowing hazard. Of course, no squeaker and half the fun is gone. For $10, I won't be buying any more of these. Sorry about that my furry friend.

Almost as good a chewing on my belt.
Size: 25 Inch
My corgi has always loved chasing her leash or a belt so I thought the snake would be a good fit for her. It quickly became her favorite. The squeakers lasted for maybe a month? Once there was a hole then we took them all out so she wouldn't choke. The snake without the squeakers is still a favorite. She's been chewing the tail end consistently and likes to lick it for some reason. I recommend this as a good tug toy. I like that it was made of leather.
