A young mathematical genius from India searches for the secrets hidden inside numbers — and for someone who understands him — in this gorgeous picture-book biography. A mango . . . is just one thing. But if I chop it in two, then chop the half in two, and keep on chopping, I get more and more bits, on and on, endlessly, to an infinity I could never ever reach. In 1887 in India, a boy named Ramanujan is born with a passion for numbers. He sees numbers in the squares of light pricking his thatched roof and in the beasts dancing on the temple tower. He writes mathematics with his finger in the sand, across the pages of his notebooks, and with chalk on the temple floor. “What is small?” he wonders. “What is big?” Head in the clouds, Ramanujan struggles in school — but his mother knows that her son and his ideas have a purpose. As he grows up, Ramanujan reinvents much of modern mathematics, but where in the world could he find someone to understand what he has conceived? Author Amy Alznauer gently introduces young readers to math concepts while Daniel Miyares’s illustrations bring the wonder of Ramanujan’s world to life in the inspiring real-life story of a boy who changed mathematics and science forever. Back matter includes a bibliography and an author’s note recounting more of Ramanujan’s life and accomplishments, as well as the author’s father’s remarkable discovery of Ramanujan’s Lost Notebook.

A biography of the Indian mathematician Srinivasa Ramanujan. The book gives a detailed account of his upbringing in India, his mathematical achievements, and his mathematical collaboration with English mathematician G. H. Hardy. The book also reviews the life of Hardy and the academic culture of Cambridge University during the early twentieth century.

"The son of a prominent Japanese mathematician who came to the United States after World War II, Ken Ono was raised on a diet of high expectations and little praise. Rebelling against his pressure-cooker of a life, Ken determined to drop out of high school to follow his own path. To obtain his father’s approval, he invoked the biography of the famous Indian mathematical prodigy Srinivasa Ramanujan, whom his father revered, who had twice flunked out of college because of his single-minded devotion to mathematics. Ono describes his rocky path through college and graduate school, interweaving Ramanujan’s story with his own and telling how at key moments, he was inspired by Ramanujan and guided by mentors who encouraged him to pursue his interest in exploring Ramanujan’s mathematical legacy. Picking up where others left off, beginning with the great English mathematician G.H. Hardy, who brought Ramanujan to Cambridge in 1914, Ono has devoted his mathematical career to understanding how in his short life, Ramanujan was able to discover so many deep mathematical truths, which Ramanujan believed had been sent to him as visions from a Hindu goddess. And it was Ramanujan who was ultimately the source of reconciliation between Ono and his parents. Ono’s search for Ramanujan ranges over three continents and crosses paths with mathematicians whose lives span the globe and the entire twentieth century and beyond. Along the way, Ken made many fascinating discoveries. The most important and surprising one of all was his own humanity."

“Dream Variation,” one of Langston Hughes's most celebrated poems, about the dream of a world free of discrimination and racial prejudice, is now a picture book stunningly illustrated by Daniel Miyares, the acclaimed creator of Float. To fling my arms wide In some place of the sun, To whirl and to dance Till the white day is done…. Langston Hughes's inspiring and timeless message of pride, joy, and the dream of a better life is brilliantly and beautifully interpreted in Daniel Miyares's gorgeous artwork. Follow one African-American boy through the course of his day as the harsh reality of segregation and racial prejudice comes into vivid focus. But the boy dreams of a different life—one full of freedom, hope, and wild possibility, where he can fling his arms wide in the face of the sun. Hughes's powerful vision, brought joyously to life by Daniel Miyares, is as relevant—and necessary—today as when it was first written.

The true story of eighteenth-century mathematician Sophie Germain, who solved the unsolvable to achieve her dream. When her parents took away her candles to keep their young daughter from studying math...nothing stopped Sophie. When a professor discovered that the homework sent to him under a male pen name came from a woman...nothing stopped Sophie. And when she tackled a math problem that male scholars said would be impossible to solve...still, nothing stopped Sophie. For six years Sophie Germain used her love of math and her undeniable determination to test equations that would predict patterns of vibrations. She eventually became the first woman to win a grand prize from France's prestigious Academy of Sciences for her formula, which laid the groundwork for much of modern architecture (and can be seen in the book's illustrations). Award-winning author Cheryl Bardoe's inspiring and poetic text is brought to life by acclaimed artist Barbara McClintock's intricate pen-and-ink, watercolor, and collage illustrations in this true story about a woman who let nothing stop her.

The author of Mesmerized shares another comical true tale of a Founding Father using science to defeat ignorance and stop the spread of false information. Thomas Jefferson was wild about numbers. He was constantly counting, measuring, and observing things that caught his interest. He loved sharing his discoveries and reading the discoveries of others. But when a famous Frenchman published a book about America, Jefferson was appalled: all the information in the book was wrong. The author insisted that America was a wretched, dismal place, where birds could not sing, dogs could not bark, and everything and everyone was puny and weak. Thomas Jefferson resolved to set the record straight — with numbers — and prove to the world that the new nation was worthy of investment. But how do you show that a country is plentiful in an age when photography hasn’t been invented yet? Mara Rockliff, master of children’s nonfiction, details another little-known moment in math and natural history, illustrated with humor by prolific artist S. D. Schindler and accompanied by extensive back matter and an informative author’s note.
