A spellbinding portrait of the Hampstead Modernists, threading together the lives, loves, rivalries and ambitions of a group of artists at the heart of an international avant-garde. Hampstead in the 1930s. In this peaceful, verdant London suburb, Barbara Hepworth and Ben Nicholson have embarked on a love affair – a passion that will launch an era-defining art movement. In her chronicle of the exhilarating rise and fall of British Modernism, Caroline Maclean captures the dazzling circle drawn into Hepworth and Nicholson's wake: among them Henry Moore, Paul Nash, Herbert Read, and famed émigrés Walter Gropius, founder of the Bauhaus, and Piet Mondrian, blown in on the winds of change sweeping across Europe. Living and working within a few streets of their Parkhill Road studios, the artists form Unit One, a cornerstone of the Modernist movement which would bring them international renown. Drawing on previously unpublished archive material, Caroline Maclean's electrifying Circles and Squares brings the work, loves and rivalries of the Hampstead Modernists to life as never before, capturing a brief moment in time when a new way of living seemed possible. United in their belief in art's power to change the world, her cast of trailblazers radiate hope and ambition during one of the darkest chapters of the twentieth century.

Humanity's love affair with mathematics and mysticism reached a critical juncture, legend has it, on the back of a turtle in ancient China. As Clifford Pickover briefly recounts in this enthralling book, the most comprehensive in decades on magic squares, Emperor Yu was supposedly strolling along the Yellow River one day around 2200 B.C. when he spotted the creature: its shell had a series of dots within squares. To Yu's amazement, each row of squares contained fifteen dots, as did the columns and diagonals. When he added any two cells opposite along a line through the center square, like 2 and 8, he always arrived at 10. The turtle, unwitting inspirer of the ''Yu'' square, went on to a life of courtly comfort and fame. Pickover explains why Chinese emperors, Babylonian astrologer-priests, prehistoric cave people in France, and ancient Mayans of the Yucatan were convinced that magic squares--arrays filled with numbers or letters in certain arrangements--held the secret of the universe. Since the dawn of civilization, he writes, humans have invoked such patterns to ward off evil and bring good fortune. Yet who would have guessed that in the twenty-first century, mathematicians would be studying magic squares so immense and in so many dimensions that the objects defy ordinary human contemplation and visualization? Readers are treated to a colorful history of magic squares and similar structures, their construction, and classification along with a remarkable variety of newly discovered objects ranging from ornate inlaid magic cubes to hypercubes. Illustrated examples occur throughout, with some patterns from the author's own experiments. The tesseracts, circles, spheres, and stars that he presents perfectly convey the age-old devotion of the math-minded to this Zenlike quest. Number lovers, puzzle aficionados, and math enthusiasts will treasure this rich and lively encyclopedia of one of the few areas of mathematics where the contributions of even nonspecialists count.

From debut author Elizabeth Schoonmaker, Square Cat shows us it's hip to be square!

No matter how hard she tries, Triangle doesn't roll like the circles, or stack like the squares. She sets off to find friends that look exactly like her. But when she finds other triangles, playtime isn't as fun. She misses shapes that roll and stack; she misses being different. So she starts a new quest.

Stunning photographs by a National Geographic photographer invite children to look around and find a world of circles, triangles, squares, and much more. Beautifully photographed, a diverse group of children explore the unexpected shapes of everyday sights and objects. "Eggs, grapes, lemons and leaves. Jellybeans, seeds, sunglasses, and balloons." They're all ovals! Shelley Rotner, an accomplished photographer and a former kindergarten teacher, gently challenges children to think creatively about shapes in real life. The lyrical text provides much for readers to consider as they find circles in the sky (the moon, the sun), squares in the playground (hopscotch), and more. A companion book to Rotner's acclaimed Colors, which received a starred review from Kirkus Reviews for it's "crisp, glowing, and crystal clear" photographs.
