This elementary text introduces basic quantum mechanics to undergraduates with no background in mathematics beyond algebra. Containing more than 100 problems, it provides an easy way to learn part of the quantum language and apply it to problems.Emphasizing the matrices representing physical quantities, it describes states simply by mean values of physical quantities or by probabilities for possible values. This approach requires using the algebra of matrices and complex numbers together with probabilities and mean values, a technique introduced at the outset and used repeatedly. Students discover the essential simplicity of quantum mechanics by focusing on basics and working only with key elements of the mathematical structure--an original point of view that offers a refreshing alternative for students new to quantum mechanics.

Not Boerboel proof
I have a terrible time finding toys for my 10 month old Boerboel. Either she ignores it or tears it up immediately.
She likes this toy (jumbo size) and actually chewed on it for 20 min. Bad side is she chewed a hole.
It lasted longer than any of the other fairly chewy toys I've tried. She doesn't like the hard chews.

Favorite Toy
Size: Medium/Large, Product Packaging: Standard Packaging
My dog is a 3.5 yr old mix and this toy has been her favorite toy by far for three years. She likes it as a squeak toy, loves it as a tug toy and can't live without it as fetch toy. I roll it on its edge outside and she chases it - sometimes it take cool bounces or swerves and sometimes its just rolls straight and fast and whatever it does she can't get enough of it. She demands we play fetch with it at least three times a day. She's not a great releaser of fetch toys so there's plenty of tugging play involved too. We've had three of these over three years, but she's 75 pounds of muscle and it gets a work out every day so it's a really tough toy. All dogs are different, so I don't know what your dog will think, but it's been a fantastic toy for our girl.

So Bad
Size: Medium/Large, Product Packaging: Standard Packaging, Size: Medium/Large, Product Packaging: Standard Packaging
Had high hopes for this toy as Kong is fantastic with aggressive chewers as or Lulu is. This toy didn't last 30 minutes before she was able to tear it apart. The rubber and plastic are not of the same quality on nearly all there other toys she has. Have found better toys for half the cost. Kong needs to do better.

Very cute, good quality
Style: Lambchop, Size: 10", Style: Lambchop, Size: 10"
Our Two year-old Great Pyrenees rescue loves her Lambchop. She’s fairly gentle with it, but it did accidentally rip so we had replace it since she loves it so much. No fault of the product. The product is very well made, She just got a little rough with it.
