In 1909 the great German physicist and Nobel Prize winner Max Planck (1858-1947) delivered a series of eight lectures at Columbia University giving a fascinating overview of the new state of physics, which he had played a crucial role in bringing about.The first, third, fifth, and sixth lectures present his account of the revolutionary developments occasioned when he first applied the quantum hypothesis to blackbody radiation. The reader is given a valuable opportunity to witness Planck's thought processes both on the level of philosophical principles as well as their application to physical processes on the microscopic and macroscopic scales.
In the second and fourth lectures Planck shows how the new ideas of statistical mechanics transformed the understanding of chemical physics. The seventh lecture discusses the principle of least action, while the final one gives an account of the theory of special relativity, of which Planck had been an early champion.
These lectures are especially important since they reflect Planck's reconsiderations and rethinking of his original discovery of quantum theory. A new Introduction by Peter Pesic places this book in historical perspective among Planck's works and those of his contemporaries. Now available in this inexpensive edition, it will be of particular interest to students of modern physics and of the philosophy and history of science.

Perfect puppy starter kit and gift! Perfect for plane rides and kennel!
Color: Neutral, Color: Neutral
Perfect puppy gift! We use the kennel as her safe haven, and for potty training . This heartbeat tool is amazing and helped our puppy get acclimated to her kennel. She goes into her kennel and sleeps with it on her own. It calmed her down on the plane completely. We had a 6-hour flight and she did fine with the heartbeat toy. At home innthe kennel, the whining was very very minimal the first couple days, then it stopped. As you would hear and see her snuggle up and fall asleep. I think it is a bit pricy, but not too bad for the benefit. The heartbeat is seperate and is putninside a pouch on the stuffed animal. The blanket is soft, beautiful and perfect size. Good quality fabric. Both chew toys were loved by her.I do notice my large breed puppy prefers the rope and small tennis ball type chew toys. However, she plays with these too. Haven't used the heating packs yet, they go inside the pouch with the heartbeat item. I am sure we will because my puppy does love to be in front of my small heater under my desk to keep my feet warm. The packaging was extremely nice and fancy and was complimentary to the items inside.

Best Idea for Puppy's First Day Home
Color: Pink
I was a bit reserved on purchasing this kit because it was a bit expensive. After a month now with my pup at home, this was the best investment for us and our GSD. On the first night, we used the heart beating snuggle puppy and blanket. She slept the entire night without an accident or a cry. The heartbeat in the snuggle puppy and the heat pad was the best idea. Our puppy never felt alone (just fyi, her crate was in the room with us for the 2 weeks).
A month later, she is so protective of her snuggle puppy. We only used 1 heat pack to soothe her during the first week. The heat packs last a while. Our GSD now uses the snuggle puppy as a pillow or an object to be close to while she is in her crate. Any new puppy owner could definitely benefit from using this. Of course, with all things puppy, it does require a bit of time to correlate toys as a positive thing. We exclusively keep the snuggle puppy in her crate and make it a part of her secure place.
My GSD puppy did really care for the teething heart toy. Even after freezing it, she didn't care for it. She also outgrew the small toy. She will chew it from time to time but it doesn't entertain her much.
I found the kit, overall, very helpful with our puppy's adjustment to our home. She sleeps through the night since 8 weeks old and now at 12 weeks old. We've never had an accident in her crate overnight with the help with the snuggle puppy.

Amazing kit for your puppy
Color: Blue
We’ve had 6 puppies over the years, and this is the first time we’ve had this wonderful little kit to welcome our little one home. We had the blanket with his litter so it smelled like them when he came home. He he loves that blanket, he loves the dog with the little heartbeat, and the teething toys.
The 5 star review is because everything in this kit is so well made, really wonderful quality, and a great value. The blanket is a very nice thick plush, not some cheap one. The stuffed dog is big and fluffy and well made, the heartbeat works wonderfully, and the little chew toys safe and well made.i would encourage anyone who’s bringing home.
A little one please get this first. It’s going to make your pup more comfortable when they get home, and will help then sleep better during the night and their naps. Very Well Done !

A must have for a new puppy.
Color: Pink
I just got my first new puppy in many years, and I was searching for ideas of what items I should get to be ready for her. A dog forum I belong to gave suggestions for items to prepare for a new pup. One of the items listed was a snuggle puppy. I was not familiar with the product, and did some research. I had always heard that lonesome puppies respond well to a hot water bottle and ticking clock for comfort. A friend had suggested a stuffed animal. I found all of that in one package - The Snuggle Puppy! And even better was the complete new puppy package. The blanket is adorable, very soft and the perfect size. The toys are perfect, and they include extra warmers for the puppy. I keep my girl in a kennel at night with her blanket and puppy. The first night I tried just the blanket, and she cried and howled for 15 minutes. Then I turned the heart beat on and put the puppy in the crate with her. Within 5 minutes she was quiet and stayed that way all night. I have used it every night since and not a peep. (It's been a week now). I would highly recommend these products to anyone bringing a pup home - it was a sleep saver for sure and she seems to love it.

Great for a small puppy
Color: Pink
Got these for my puppy, a German shepherd, while it was functional, she loved it, as it was chewability, durability and ease of use.
