Computers are everywhere today--at work, in the bank, in artist's studios, sometimes even in our pockets--yet they remain to many of us objects of irreducible mystery. How can today's computers perform such a bewildering variety of tasks if computing is just glorified arithmetic? The answer, as Martin Davis lucidly illustrates, lies in the fact that computers are essentially engines of logic. Their hardware and software embody concepts developed over centuries by logicians such as Leibniz, Boole, and Godel, culminating in the amazing insights of Alan Turing. The Universal Computer traces the development of these concepts by exploring with captivating detail the lives and work of the geniuses who first formulated them. Readers will come away with a revelatory understanding of how and why computers work and how the algorithms within them came to be.Binding Type: Hardcover

Great product
Size: King, Color: White
I absolutely love this king-size bedding! The material feels incredibly soft and comfortable, making it perfect for a great night’s sleep. It fits my king bed perfectly with plenty of coverage, and it stays in place without bunching up. The quality is excellent—it feels durable, well-made, and has held up nicely after washing without or shrinking.

Soft and fluffy
Size: King, Color: White
Very fluffy! I’ve been searching for one like this for YEARS that can replicate that fluffy hotel style feeling. Great quality, it’s a cool white color. Very warm. It has the little bands on the edges for your duvet cover to attach to. Perfect fit.

Lightweight, Comfortable All-Season Comforter for Everyday Use
Size: Queen, Color: Black, Size: Queen, Color: Black
After using this comforter for a few months now, I've found it very comfortable overall. While it is lightweight, it does provide adequate warmth on those cooler evenings. I do appreciate that it doesn't trap too much heat, meaning I've been able to use it comfortably in many different temperatures.
The fabric of this comforter is soft, and it was very fluffy when I received it and ready to use. The design is quite simple and clean, with box-stitching to keep the filling in place; I did notice some spots where the filling does not seem to be filling evenly, but it has not affected how I feel about the comforter or how I have used it. It is easy to pull apart on the bed, so it doesn't feel bulky while making a bed.
Because it is affordable and high quality, I think this is a good option if you are looking for low-maintenance comfort throughout the year. If you are looking for something that is thick and heavy like those found in hotel rooms, then this comforter may not be thick enough for your needs.

Great All-Season Comforter, Soft and Fluffy and Great Quality
Size: Queen, Color: Beige
This Comforter really surpassed my expectations by providing great value and quality which pleasantly nurtures me in my sleep. It provides a soft and fluffy fabric which makes a really comfortable experience for long periods of sleep. The color was spot on with no flaws and the fit was ideal. The comforter keeps warm nicely without overheating while also being cool if I’m too hot. The comfort surpassed other competitors with the softness and amazing qualities with no flaws in it. I would personally recommend it because it offers a lot without breaking the bank with its high quality and value and the comfort.
