British-Israeli recreational mathematician, communicator and educator, Yossi Elran explores in-depth six of the most ingenious math puzzles, exposing their long 'tails': the stories, trivia, quirks and oddities of their history and, of course, the math and mathematicians behind them. In his unique 'talmudic', associative way, Elran shows the hidden connections between Lewis Carroll's 'Cats and Rats' puzzle and the math of taxi driving, a number pyramid magic trick and Hollywood movie fractals, and even how packing puzzles are related to COVID-19!Elran has a great talent for explaining difficult topics — including quantum mechanics, a topic he relates to some original 'operator' puzzles — making the book very accessible for all audiences.With over 40 additional, original puzzles, and touching on dozens of hot math topics, this is a perfect book for math lovers, educators, kids and adults, and anyone who loves a great read.Yossi Elran is co-author of our bestselling The Paper Puzzle Book, and heads the Innovation Center at the Davidson Institute of Science Education, the educational arm of the world-renowned Weizmann Institute of Science in Israel.

'This is a marvellous book. The diversity of possible puzzles that can be given with these very limited resources, which are basically some paper and scissors, is overwhelming, and the challenges are sometimes very tough. Even the two-star problems may be hard for an untrained puzzler. This is medicine against boredom on long rainy days, but be careful not to get addicted or it may suck up your less empty and sunny days as well.'

Expanding on the National Research Council's Guide for the Care and Use of Laboratory Animals, this book deals specifically with mammals in neuroscience and behavioral research laboratories. It offers flexible guidelines for the care of these animals, and guidance on adapting these guidelines to various situations without hindering the research process. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research offers a more in-depth treatment of concerns specific to these disciplines than any previous guide on animal care and use. It treats on such important subjects as: The important role that the researcher and veterinarian play in developing animal protocols. Methods for assessing and ensuring an animal's well-being. General animal-care elements as they apply to neuroscience and behavioral research, and common animal welfare challenges this research can pose. The use of professional judgment and careful interpretation of regulations and guidelines to develop performance standards ensuring animal well-being and high-quality research. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research treats the development and evaluation of animal-use protocols as a decision-making process, not just a decision. To this end, it presents the most current, in-depth information about the best practices for animal care and use, as they pertain to the intricacies of neuroscience and behavioral research.

This gorgeous 150th anniversary edition of Alice's Adventures in Wonderland is also a revelatory work of scholarship. Alice's Adventures in Wonderland--published 150 years ago in 1865--is a book many of us love and feel we know well. But it turns out we have only scratched the surface. Scholar David Day has spent many years down the rabbit hole of this children's classic and has emerged with a revelatory new view of its contents. What we have here, he brilliantly and persuasively argues, is a complete classical education in coded form--Carroll's gift to his "wonder child" Alice Liddell. In two continuous commentaries, woven around the complete text of the novel for ease of cross-reference on every page, David Day reveals the many layers of teaching, concealed by manipulation of language, that are carried so lightly in the beguiling form of a fairy tale. These layers relate directly to Carroll's interest in philosophy, history, mathematics, classics, poetry, spiritualism and even to his love of music--both sacred and profane. His novel is a memory palace, given to Alice as the great gift of an education. It was delivered in coded form because in that age, it was a gift no girl would be permitted to receive in any other way. Day also shows how a large number of the characters in the book are based on real Victorians. Wonderland, he shows, is a veritable "Who's Who" of Oxford at the height of its power and influence in the Victorian Age. There is so much to be found behind the imaginary characters and creatures that inhabit the pages of Alice's Adventures in Wonderland. David Day's warm, witty and brilliantly insightful guide--beautifully designed and stunningly illustrated throughout in full colour--will make you marvel at the book as never before.

A fully annotated and illustrated version of both ALICE IN WONDERLAND and THROUGH THE LOOKING GLASS that contains all of the original John Tenniel illustrations. From "down the rabbit hole" to the Jabberwocky, from the Looking-Glass House to the Lion and the Unicorn, discover the secret meanings hidden in Lewis Carroll's classics. (Orig. $29.95)
