Sources of Quantum MechanicsMax Planck's famous lecture of 1900 expressed quantum theory in its essential form, but his statement was just the beginning. This volume features seventeen early papers that developed quantum theory into its modern form.

Max Planck's famous lecture of 1900 expressed quantum theory in its essential form, but his statement was just the beginning. This volume features seventeen early papers that developed quantum theory into its modern form. These papers appeared from 1917 to 1926 and were written by the leading physicists of the early twentieth century.The collection begins with Einstein's "On the Quantum Theory of Radiation," an illuminating derivation of Planck's Law. Other important early papers by Ehrenfest, Bohr, Born, Van Vleck, Kuhn, and others prepared the way for the "turning point" in quantum mechanics. This crucial step is taken in Heisenberg's paper "Quantum-Theoretical Re-Interpretation of Kinematic and Mechanical Relations." Additional papers by Born, Dirac, Pauli, and Jordan develop the theory in full. Eleven of these seventeen papers are reproduced unabridged; all are in English.
A 59-page historical introduction by the editor, Professor B. L. van der Waerden, provides connective commentary. Quoting from relevant correspondence, noting the thinking behind each discovery, and evaluating the extent of each individual's contribution, it re-creates the era's intellectual foment and excitement.

It’s wonderful!!
Size: 2' x 3' (Single Pelt), Color: Brown, Size: 2' x 3' (Single Pelt), Color: Brown
The product is wonderful! You know it is real, coz the smell doesn’t go away. I use it to meditate and cannot how nicely it created the perfect comforting barrier to help elevate my experience. I however want to find alternatives coz I stopped using animal products after turning a vegetarian. The size (it is bigger in person than in the pic) and color(brown) are perfect for what I do and doesn’t need much/any maintenance!
The white however needs a lot of attention and care.I’m sure it would last a decade and the weight is just right too!

Beautiful lux sheepskin, you won't be disappointed!
Size: Single Pelt/2 ft x 3 ft, Color: Grey
I just got this today, 2 day delivery. It's a beautiful silver grey 2'x3', no smell, no shedding, super soft and has a luxurious feel. I can't believe it's real and so affordable! I have it draped on an ottoman in front of the couch. I love it and already want to buy a few more for my mid century modern couch and chairs. So chic! Highly recommend!

Very nice if you aren't too pick on actual color.
Size: Single Pelt/2 ft x 3 ft, Color: Blue
Colors may vary. I really liked this, it was the perfect size and that perfect combination of soft and fluffy, but not being "too fluffy" and looking like a shaggy dog that needed a haircut. My only complaint was the color. Supposed to be blue, and I know monitors and lighting distort stuff but this was an obvious turquoise/teal. Much much greener than I was looking for. I could have made any variant of an actual blue work from powder baby to practically navy, but not this. I had to return, but other than the color, this seemed to be a very nice rug. Sad the color was so off.
