מטעויות לתגליות - סיפורים אמיתיים שהתחילו באוי לא והסתיימו באוי כן ! על התגליות הרבות במהלך ההיסטוריה שנולדו בטעות ושינו את פני העולם שלנו. 
הרופא אלכסנדר פלמינג שכח לסגר חלון וגילה את האנטיביוטיקה! הימאי כריסטופר קולומבוס תעה בלב ים והגיע ליבשת אמריקה! המדען וילהלם רנטגן ראה נצנוץ באפלה והביא לפריצת דרך ברפואה! בסיפורים האמיתיים שבספר תוכלו לצאת למסע מרתק מטעויות לתגליות וללמוד איך צנצנת שבורה הצילה מיליוני אנשים מתאונות, איך חומר ניקוי ישן הפך לאחד המשחקים שילדים הכי אוהבים, ואיך חטיף מקולקל הוביל להמצאת התנור המהיר בעולם. כי מי שרואה בטעות הזדמנות להתבונן, ללמוד ולחקור — מגלה דברים נפלאים! את הסיפורים כתבה תמי שם־טוב שספריה לילדים ולנער, ובהם סדרת "ממציאים ומגלים" זכו בשבחי הביקורת ותרגמו לשש שפות. 
"זהו ספר חשוב לילדים ולהוריהם, שאם רק ישכילו להבין את ערכן האמתי של טעויות, ילמדו להשתחרר מהפחד להיכשל ויוכלו להצליח יותר ולהיות מאושרים יותר." ד"ר טל בן־שחר, מחבר רב־המכר "באושר ובאושר"
