"A great read for anyone interested in puzzles or mathematics." --Publishers Weekly

"Gift Guide Selection 2015. Moscovich, a celebrated puzzle inventor, makes a compelling case for puzzle solving as a means of developing creativity and even intelligence." --American Scientist

"The Puzzle Universe is a quixotic, informative and enlightening encyclopedia of recreational mathematics. It should prove to be an inspiration to mathematical idlers, and a rich resource for learners and teachers who wish to be attuned to the playful and creative side of mathematics." --Mathrecreation Blog

The Puzzle Universe is intended for general readers and devoted puzzlers but it has also found its way into school libraries and curricula. It is about the latent beauty of mathematics, its history and the puzzles that have emerged from the science of numbers. It is full of challenging historical facts, thinking puzzles, paradoxes, illusions and problem solving.

A historical and pedagogical dimension sets The Puzzle Universe apart. The 315 puzzles are described in extended captions that explain in easy terms the story of the puzzles' origins and attempts to solve them, the value of puzzles to education, and the development of the mathematical sciences in light of recent research and unmet challenges. There are many profiles of great mathematicians.

The puzzles appear in a dynamic layout for a visual experience that is the author's trademark. There are ten chapters complete with answers. Icons rate the challenge and indicate the tools needed (pencil, scissors, ruler and, of course, your thinking cap).

With this book, Ivan Moscovich invites readers to join him in the puzzle universe, an edifying environment of creative discovery, problem solving and fun.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!
