Here is Poincare's famous discussion of creative psychology as it is revealed in the physical sciences. Explaining how such basic concepts as number and magnitude, space and force were developed, the great French mathematician refutes the skeptical position that modern scientific method and its results are wholly factitious. The places of rigorous logic and intuitive leaps are both established by an analysis of contrasting methods of idea-creation in individuals and in modern scientific traditions. The nature of hypothesis and the role of probability are investigated with all of Poincare's usual fertility of insight.Partial contents: On the nature of mathematical reasoning. Magnitude and experiment. Space: non-Euclidean geometrics, space and geometry, experiment and geometry. Force: classical mechanics, relative and absolute motion, energy and thermodynamics. Nature: hypotheses in physics, the theories of modern physics, the calculus of probabilities, optics and electricity, electro-dynamics.
"Poincare's was the last man to take practically all mathematics, both pure and applied as his province. Few mathematicians have had the breadth of philosophic vision that Poincare's had, and none is his superior in the gift of clear exposition." Men of Mathematics, Eric Temple Bell, Professor of Mathematics, University of Cambridge"

High quality sheepskin!!
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
This sheepskin was purchased as a "chair cover" for my pets. It arrived with very nice packaging, along with detailed care instructions. The sheepskin was advertised as being"not white" online, and the company made very sure to state that the fur has an "off white/yellow" color. That was a little concerning for me, and I wasn't really sure whether it would have an off color, but it arrived exactly as described. There were no obvious discolorations, spots, or blemishes. In fact, it arrived as a soft "off white" color that is very beautiful and exquisite. The fur has a plush, even look, and there is no matting or fuzzy, "neglected teddy bear look" at all!
I actually purchased another brand to see if I could distinguish the difference between the two. This particular sheepskin is by far the better of the two purchases.
FYI: When the package was opened, there was no distinct odor. That's a huge plus!
I will admit that the size was slightly smaller than expected. It really doesn't matter much in the space I'm using it for though. My miniature Dachshund loves it!
If you're trying to find a high quality sheepskin, and you don't need to cover a very large space, this is definitely the one to buy!

The Quality of the sheepskin is awesome.
Color: Wolf Tip, Size: 2' x 3' (Natural)
This rug is a beautiful specimen of New Zealand sheep. The rug is very very soft, the rug is thick, and the brown tips are fabulous looking. All in all I'm very pleased with this purchase. The size is perfect as it measures 2' x 3'. I would buy again from this seller.

Plush rug that’s super soft. WOW!
Color: Natural (Yellow-white Ivory), Size: 6' x 7' (Natural)
Beautiful and super plush! I use it as an outer blanket when cold weather camping. Like a modern day cave man. One of my favorite purchases. I avoid kneeling on it while it’s on my mattress fearing it might split the hide, or damage the stitching. It fits my queen size camper bed. Cant say enough!

Big Investment for a Lifetime of Quality
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
Several reviews mentioned a smell lingering with the sheepskin even after being unpacked a few days. I did notice the smell when I unpacked it, but I would expect a slight odor from such an item. It was not overpowering and is completely gone after one month of having it laid out on a chest in our bedroom. It is very functional, can be sat on, knelt on, etc, but is easily brushed off and looks great! The quality is very good…someone in my family is on it every night, and we have experienced no shedding whatsoever.
Although the price is a big investment initially, I believe the quality is worthy. We plan to enjoy this beautiful sheepskin for a lifetime!
