Sometimes, the bug in your program is not a visual bug, not by algorithm, syntax error but is a real bug, an animal. HEY!!! You should borrow it because it is free and interesting. I would be happy to lend to you! ----------------------- Product details and description from Amazone Age Range: 5 and up Grade Level: Kindergarten - 2 Hardcover: 48 pages Publisher: Sterling Children's Books (May 16, 2017) Language: English ISBN-10: 1454920009 ISBN-13: 978-1454920007 Product Dimensions: 8.8 x 0.5 x 11 inches Shipping Weight: 1 pounds #Science & Technology #Women #Programming “If you’ve got a good idea, and you know it’s going to work, go ahead and do it.” The inspiring story of Grace Hopper—the boundary-breaking woman who revolutionized computer science—is told told in an engaging picture book biography. Who was Grace Hopper? A software tester, workplace jester, cherished mentor, ace inventor, avid reader, naval leader—AND rule breaker, chance taker, and troublemaker. Acclaimed picture book author Laurie Wallmark (Ada Byron Lovelace and the Thinking Machine) once again tells the riveting story of a trailblazing woman. Grace Hopper coined the term “computer bug” and taught computers to “speak English.” Throughout her life, Hopper succeeded in doing what no one had ever done before. Delighting in difficult ideas and in defying expectations, the insatiably curious Hopper truly was “Amazing Grace” . . . and a role model for science- and math-minded girls and boys. With a wealth of witty quotes, and richly detailed illustrations, this book brings Hopper's incredible accomplishments to life.
