Pi in the Sky: Counting, Thinking, and BeingJohn D. Barrow's Pi in the Sky is a profound and profoundly different exploration of the world of mathematics: where it comes from, what it is, and where it's going to take us if we follow it to the limit in our search for the ultimate meaning of the universe.

John D. Barrow's Pi in the Sky is a profound -- and profoundly different -- exploration of the world of mathematics: where it comes from, what it is, and where it's going to take us if we follow it to the limit in our search for the ultimate meaning of the universe. Barrow begins by investigating whether math is a purely human invention inspired by our practical needs. Or is it something inherent in nature waiting to be discovered? In answering these questions, Barrow provides a bridge between the usually irreconcilable worlds of mathematics and theology. Along the way, he treats us to a history of counting all over the world, from Egyptian hieroglyphics to logical friction, from number mysticism to Marxist mathematics. And he introduces us to a host of peculiar individuals who have thought some of the deepest and strangest thoughts that human minds have ever thought, from Lao-Tse to Robert Pirsig, Charles Darwin, and Umberto Eco. Barrow thus provides the historical framework and the intellectual tools necessary to an understanding of some of today's weightiest mathematical concepts.Binding Type: Paperback

"Stylish and Functional Guess Wallet!"
This is a fantastic wallet that combines style and practicality! The sleek black design features the iconic Quattro G monogram print on the leather (or faux-leather). It has a contrasting stripe with the "GUESS" logo on the front, giving it a modern and sophisticated edge.
Despite its slim, compact silhouette, it offers great organization. It typically includes multiple card slots, slip pockets, a clear ID window, and a full-size bill compartment, providing ample space for all your essentials while keeping a flat profile in your pocket.
Many customers appreciate the durable material and the high-end look without the high-end price. It often comes in a gift box, making it an ideal present for any occasion. Overall, it's a stylish and functional accessory that reflects the brand's fashionable legacy.

Best wallet ever!
Size: One Size, Color: Black/Red
Great wallet! Super slim, holds all my cards perfectly, not that I ever have cash to put in it anyway. At this point, it’s basically a stylish card organizer that reminds me I’m broke every time I open it. Still, it looks good, feels durable, and makes me look like I have my life together, until the card gets declined.
