This true story of the incredible horse whose smarts stumped all of Berlin and changed science reads like a fabulous STEM mystery. Clever Hans was a horse who could do math problems, tell time, read, spell, and more . . . or could he? Even after seeing Hans answer questions correctly, some people thought it must be a hoax. Scientists began to investigate. Eventually, one scientist had a groundbreaking "aha!" moment and realized Hans was clever in a way no one had even imagined. Turns out Hans was so smart, he changed science!

Can a horse really do arithmetic? For a time a great many people thought so, enthralled by the exploits of Clever Hans, a horse that could seemingly answer any question about mathematics, language, and music with stomps of his hoof. Even as celebrated scientists endeavored to discover Hans’s secret, people were perfectly comfortable believing something no rational mind should have accepted. How is that possible? In The Horse That Won’t Go Away, Tom Heinzen, Scott Lilienfeld, and Susan Nolan explore the confounding story of Clever Hans and how we continue to be deceived by beliefs for which there is no supporting logic or evidence. From Clever Hans, to the unsupported claims that facilitated communication could allow persons with autism to communicate, to the exaggerated fear of many parents that their child may be kidnapped (the odds of such an event are astronomical), the authors show just how important it is to rely on the scientific method as we navigate our way through everyday life.

Hans was in love with a girl named Gretel. They saw each other every day and every time Gretel gave Hans a gift. Hans was however not that smart, so he mishandled the gifts. Gretel gave Hans a needle and he stuck it in a hay. His mother told him that it was going to be better to stick it through his sleeve. And so he did the next day. However the gift was not a needle, but a knife. You can imagine the misunderstanding that had occurred. The story continues with Hans’ misfortunes. Will Gretel agree to marry him after she witnesses his stupidity so many times? Find out in Brothers Grimm’s "Clever Hans". Children and adults alike, immerse yourselves into Grimm’s world of folktales and legends! Come, discover the little-known tales and treasured classics in this collection of 210 fairy tales. Brothers Grimm are probably the best-known storytellers in the world. Some of their most popular fairy tales are "Cinderella", "Beauty and the Beast" and "Little Red Riding Hood" and there is hardly anybody who has not grown up with the adventures of Hansel and Gretel, Rapunzel and Snow White. Jacob and Wilhelm Grimm’s exceptional literature legacy consists of recorded German and European folktales and legends. Their collections have been translated into all European languages in their lifetime and into every living language today.

In this provocative book, Douglas Candland shows that as we begin to understand the way animals and non-speaking humans "think," we hold up a mirror of sorts to our own mental world, and gain profound insights into human nature. Weaving together diaries, contemporary newspaper accounts, and his own enlightening commentary, Candland brings to life a series of extraordinary stories. He begins with a look at past efforts to civilize feral children. We meet Victor, the Wild Boy of Aveyron, now famous as the subject of a Truffaut film; Kaspar Hauser, raised in a cell, civilized, and then assassinated; and the Wolf Girls of India, found early this century huddled among wolf pups in a forest den (they were originally believed to be ghosts by superstitious villagers, who nearly shot them as they were being captured). In each case, it was hoped that the study of these children would help clarify the age-old nature/nurture debate, but, as Candland shows, so much of the information "revealed" was really only a projection of beliefs previously held by the investigating scientists. Candland then turns to "clever animals." We learn how the investigation of "Clever Hans," the German horse who could calculate square roots, proved to be a first step in the direction of behaviorism (researchers found that Hans was being tipped off by the subtle and unwitting body language of his owner and other observers, who would bend almost imperceptibly at the waist with every hoof beat, and stand erect when the correct count was reached). And Candland discusses the many attempts to communicate with our closest neighbor, the apes. We read of Richard Lynch Garner's 1892 experiment living with chimpanzees in Gabon (he taught one to say the French word "feu"), and of Gua, raised by W.N. and L.A. Kellogg alongside their own son Donald, and of the latest successes of teaching sign language to such precocious apes as Sarah, Sherman, Austin, and Koko. Throughout, Candland illuminates the boldest and most intriguing efforts yet to extend our world to that of our fellow creatures. And he shows that, in the end, our effort to "make contact" is a reflection of the way in which we as a species create and order our universe. Humans have long shown a wish to connect with the silent minds around them. In assembling and interpreting the compelling tales in this book, Candland offers us a new understanding not only of the animal kingdom, but of the very nature of humanity, and our place in the great chain of being.

Chaser has a way with words. She knows over a thousand of them—more than any other animal of any species except humans. In addition to common nouns like house, ball, and tree, she has memorized the names of more than one thousand toys and can retrieve any of them on command. Based on that learning, she and her owner and trainer, retired psychologist John Pilley, have moved on to further impressive feats, demonstrating her ability to understand sentences with multiple elements of grammar and to learn new behaviors by imitation. John’s ingenuity and tenacity as a researcher are as impressive as Chaser’s accomplishments. His groundbreaking approach has opened the door to a new understanding of animal intelligence, one that requires us to reconsider what actually goes on in a dog’s mind. Chaser’s achievements reveal her use of deductive reasoning and complex problem-solving skills to address novel challenges. Yet astonishingly, Chaser isn’t unique. John’s training methods can be adopted by any dog lover. Through the poignant story of how he trained Chaser, raised her as a member of the Pilley family, and proved her abilities to the scientific community, he reveals the positive impact of incorporating learning into play and more effectively channeling a dog’s natural drives. John’s work with Chaser offers a fresh perspective on what’s possible in the relationship between a dog and a human. His story points us toward a new way of relating to our canine companions that takes into account our evolving understanding of the way animals and humans learn.
