    Though also a bestseller at the time, Just David has rarely been reprinted since its release in 1916. We felt a story this good shouldn’t be so hard to find, so we decided to put it back in print last year. Now it’s in a longer-lasting hardcover.It is the story of David, a charming little boy of 10 who is suddenly transplanted from a world of music (he plays the violin) in the mountains with his father, to the provincialism of a workaday small town. But even more, it is the story of how David transplants his own character, courage and happiness into the lives of the people he meets, and wins their love and respect. Here’s what we say in the preface to the new edition:Just David is a quiet, unassuming children’s novel about an orphaned young boy with a mysterious past. David, not the typical boy found in most stories of his day, is a mixture of simplicity and complexity whose disarming innocence has a profound effect on the people he encounters. Unlike the “good bad boy” often encountered in children’s literature, David is a “good good” boy. He is not in any way “goody-goody” in the moralistic sense, but simply and purely good. David’s goodness is not a mysterious quality that defies logic and imagination, but rather a quality cultivated in him by the intentional efforts of a wise and loving father. During David’s formative years, his father secluded him from the influences of the outside world, creating a private world in the mountains filled with simple pleasures, purposeful study, and beautiful music. David’s touching story is well within the scope of the imagination, and David’s endearing innocence, engaging personality, and natural character are unforgettable.Just David struck a resonant chord in our family for several reasons. First, David’s life affirms the biblical principle expressed in the proverb, “He who walks with the wise grows wise, but a companion of fools suffers harm”. David walked with his father and became wise. Also, his story reminds us of the importance of creating the right “appetite” early in our children’s lives. David’s love of music, nature and beauty were intentionally cultivated in him by his father. Finally, there is a refreshing balance in David’s life and character that provides a literary model to emulate, especially for the more artistically-inclined boy often overlooked in literature. David is artistic, yet he knows when to be realistic. He is slight of stature, yet able to handily defend himself when necessary. He is trained and mannerly, yet he is also manly. He is sensitive, yet sensible. Whatever limitations he discovers, he meets them with strength of character.This is truly one of those books that everyone in your family will like, and will likely want to hear or read more than once. We’re on our fourth reading! It has even inspired us to have Just David days for our children when we focus on the beautiful and lovely things God has given us to enjoy. Just David is just great. Includes family discussion questions at the end of the book.--Whole Heart Ministries

    Written with student centred, pedagogically driven approach, the text provides a self-contained introduction to the theory of signals and systems. This book looks at the concepts of systems, and also examines signals and the way that signals interact with physical systems. It covers topics ranging from basic signals and systems to signal analysis, properties of continuous-time Fourier transforms including Fourier transforms of standard signals, signal transmission through linear systems, relation between convolution and correlation of signals, sampling theorems and techniques, and transform analysis of LTI systems. All the solved and unsolved problems in this book are designed to illustrate the topics in a clear way.

    Abbott published a brilliant novel about mathematics and philosophy that charmed and fascinated all of England. As both a witty satire of Victorian society and a means by which to explore the fourth dimension, Flatland remains a tour de force. Now, British mathematician and accomplished science writer Ian Stewart has written a fascinating, modern sequel to Abbott's book. Through larger-than-life characters and an inspired story line, Flatterland explores our present understanding of the shape and origins of the universe, the nature of space, time, and matter, as well as modern geometries and their applications. The journey begins when our heroine, Victoria Line, comes upon her great-great-grandfather A. Square's diary, hidden in the attic. The writings help her to contact the Space Hopper, who becomes her guide and mentor through eleven dimensions. Along the way, we meet Schröger's Cat, The Charming Construction Entity, The Mandelblot (who lives in Fractalia), and Moobius the one-sided cow. In the tradition of Alice in Wonder-land and The Phantom Toll Booth, this magnificent investigation into the nature of reality is destined to become a modern classic.

    Mouse! They'd been calling him that since he was born. He hadn't used to mind it, even liked it once, but not anymore. He poked at some crackers on the table. "Someday I'll be so strong," he mumbled. "Someday . . ."And then it happened. Something so strange, Daniel wasn't sure he could believe his eyes. One little cracker trembled for a second, then lifted up off the table. Not much. Not even an inch. Then, just as suddenly, it dropped right back down. Daniel blinked. Had that really happened? How? Had he done it?Up is the story of an ordinary boy with an extraordinary talent, a talent no one knows about but him. Can Mouse really lift things off the ground? Or is it enough that he believes he can? Once again Jim LaMarche has mixed the magical with the everyday to create a book that stretches our imaginations and our dreams.

    . . in which Sydney Padua transforms one of the most compelling scientific collaborations into a hilarious series of adventures. Meet Victorian London’s most dynamic duo: Charles Babbage, the unrealized inventor of the computer, and his accomplice, Ada, Countess of Lovelace, the peculiar protoprogrammer and daughter of Lord Byron. When Lovelace translated a description of Babbage’s plans for an enormous mechanical calculating machine in 1842, she added annotations three times longer than the original work. Her footnotes contained the first appearance of the general computing theory, a hundred years before an actual computer was built. Sadly, Lovelace died of cancer a decade after publishing the paper, and Babbage never built any of his machines. But do not despair! The Thrilling Adventures of Lovelace and Babbage presents a rollicking alternate reality in which Lovelace and Babbage do build the Difference Engine and then use it to build runaway economic models, battle the scourge of spelling errors, explore the wilder realms of mathematics, and, of course, fight crime—for the sake of both London and science. Complete with extensive footnotes that rival those penned by Lovelace herself, historical curiosities, and never-before-seen diagrams of Babbage’s mechanical, steam-powered computer, The Thrilling Adventures of Lovelace and Babbage is wonderfully whimsical, utterly unusual, and, above all, entirely irresistible.(With black-and-white illustrations throughout.)
