היסטוריה של המדע לצעירים מכל הגילים - הזמנה להרפתקה של גילויים מדעיים מרתקים. הפליאה הגדולה של העולם נמשכת: איך כל זה קורה?
מאז ומעולם בני האדם לא הפסיקו לתהות, לבדוק, להתנסות ולחשב. בואו לטוס לכוכבים באמצעות הטלסקופ, לראות איך השמש יורשת את מקומו של כדור הארץ במרכז היקום. למדו על הופעת הכימיה ועל פיתוח הטבלה המחזורית, והתוודעו להסברים הפיזיקליים לחשמל, לכוח המשיכה, ולמבנה האטום. גלו מה הוביל לגילוי הדנ”א ופתח בפני החוקרים את סודות החיים. הכירו סיפורים מרתקים של גיבורי מדע, מפורסמים ומפורסמים - פחות, ואלפי שנות מחקר מאלפות.
