This is a thorough treatment in one volume of the mathematical techniques vital in classical mechanics, electromagnetic theory, quantum theory, and relativity. Designed for junior, senior, and graduate courses in mathematical physics, it presents full explanations of function theory, vectors, matrices, dyadics, tensors, partial differential equations, and other advanced mathematical techniques in their logical order during the presentation of the various physical theories. The completeness of the derivations makes the book especially useful for self-study.Several topics seldom presented, such as electron theory and relativity, appear in considerable detail, because an understanding of them is increasingly vital to the student of atomic physics. But the author's treatment of his chosen subjects in classical physics is no way slighted, and his book has proved valuable to students in all fields of physics.
The opening section provides scores of definitions, conversion factors, dimensional constants, and electromagnetic quantities for ready reference later on. There follows a full treatment of the main branches of classical physics: potential theory, spherical harmonics, vector analysis, dyadics, matrices, tensors, hydrodynamics, advanced dynamics, waves and vibrations, quantum mechanics, electromagnetic theory, and radiation theory. The book concludes with a discussion from first principles of the theory of relativity.
Nearly 200 problems ranging over a wide level of difficulty and selected from many different fields of physics are included, with answers, at ends of chapters.
"The treatment is more detailed than normal for an advanced text . . . excellent set of sections on Dyadics, Matrices, and Tensors. . . . The part on waves and vibrations is well done . . . problems well varied in difficulty." ― Journal of the Franklin Institute.

Great treat toy especially for frozen treats
Style: Chilly Penguin, Size: Medium/Large (Pack of 1)
This is cute! Very solid and chewable. To ensure a longer play time it does great for popping in the freezer after filling with peanut butter, yogurt, pumpkin, applesauce, broth, dog ice cream etc ...
It's been so much cleaner and easier than putting it in a dish; the treat lasts longer and the dog is entertained longer.
Whether frozen or not, this toy is very easy for my dog to get everything / lick clean. It's very easy to clean either putting in the top shelf of dishwasher or hand washing with a bottle brush.
Treat of no treat, this is entertaining for my dog. He likes to simply run around with it in his mouth or randomly chew on it. This is different from his balls or bones because it's kind of flat and thin.
Good buy and great to help cool him off from the warm weather.

Dogs love the treats hidden within
Style: Chilly Penguin, Size: Small (Pack of 1)
The treat holding penguin is ideal for feeding treats, frozen and otherwise, to your loving pets. I have put yogurt, applesauce, mashed bananas, and other treats inside the penguin. The puppies love licking the yummy treats out of the penguin. It occupies them for quite a while. The only thing is that they are not very easy to clean. I use a small soft brush after soaking them in hot water.

wonderful - best dog toy on the market!!
Style: Chilly Penguin, Size: Small (Pack of 1), Style: Chilly Penguin, Size: Small (Pack of 1)
my 10.6 lb shih tzu mix loves these. yes, they are durable. this is the third dog on some of them. i fill with diluted baby food mixed with 3 drops honey, carrots in todays, or peanut butter and a tad of jelly mixed with water, or water with unsalted cooked veggies like broccoli or cauliflower stems and carrot bits, or baked and mixed with water sweet potato. she eats just anout any vegetable. the water is to reduce calories as i had to take 3 lbs off her when i got her. and yes, they stack nicely.
when i let her out of her crate, she looks and grabs it and puts it on the kitchen floor for a refill. her idea, not my training but i like it.
this is an addition to my previous review. as far as i'm concerned, this is the best toy on the market for very small dogs. my dog has been at target weight for 2 years now and i restrict her treat calories to a strict 21 kcals daily. she is also now a working dog. i have now done frozen greek yogurt with apples and blueberry baby food diluted, kibble mixed in water. wet dog food diluted with water etc. i leave her in her crate with one and two cameras on her, one two way audio and she has stopped all barking and dutifully brings the toy and actually deposits it in my hand when i let her out of the crate. every 2-3 days it's like a new toy flavor and no toys have and tooth marks or anything on them. they're used daily.
understand this lil 10.6 lb dog goes thru nylon power chews regularly so she's super capable of destroying toys but i think the little bit of food satisfies her with the penguin and 2 1/2 years in, she has no desire to destroy them. i now own 8 of these as 2 stay in her travel bag.
we would be heartbroken if the company quit making these penguins. fantastic product. the small would even have worked for my 5 lb papillons had they made them then.

Great durability and utility
Style: Chilly Penguin, Size: Medium/Large (Pack of 2)
I love the size of these and the sturdiness. I freeze bone broth and put it in the crate or give it to dogs when it gets warm out. To help them cool or help them with teething. They have decimated other holders of frozen liquid, but these have lasted well. They also do not get sharp edges when chewed on by English bulldogs.
