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. 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
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

My son destroys shoes, same thing happened here.
Size: 5 Big Kid, Color: Black
For some reason my son started doing the duck walk at school and while performing this little trick for his classmates he ripped the rubber that wraps over top the toe. Now, instead of being glued up and into place, its basically sagging down. Thankfully that's the only thing that's gone wrong with these and honestly this sort of wear and tear is not typical. What I would say is that if your child is rough on shoes, I would pass on these. They are very nice, very light weight and are great for school. However, due to the design, they might not best good for some kids.
In terms of sizing and comfort, my son wears a 5 and these fit him very well. He has wide feet like his dad, and these don't bother him at all. He's says they're very comfortable and does enjoy wearing them.

No tying necessary
Size: 1 Little Kid, Color: Fuchsia, Size: 1 Little Kid, Color: Fuchsia
I ordered a kids size 1 for my child, and so far, I’ve been really happy with these shoes.
Here’s what I like:
✅ Stylish design and comfortable fit. My daughter loves wearing these.
✅ They don’t show scuffs or scratches easily.
✅ The color is what I expected from the item pictures and it’s really cute.
✅ The Velcro straps make these easy to get off and put on.
✅ There’s a piece of Velcro on the tongue to help keep it in place. Really smart.
✅ The seams have not pulled apart and overall, these seem to be really well made.
They have offered good support for my child’s feet, and a shoe that my child can put on by themselves is a win for me!

Durable girls sneakers
Size: 1 Little Kid, Color: Fuchsia, Size: 1 Little Kid, Color: Fuchsia
These Saucony girls sneakers in fuchsia are great. The design and coloring are fun and vibrant and the cushioning on the insole is good with just enough bounce. The material and construction seem durable. The Velcro strap secures in two places so you get a snug fit without the shoe “tongue” moving around.
The sizing seems true to size. Overall these are a very solid, comfortable and functional pair of sneakers. $47, the current price, is about the price for similar products these days.
