Who was the first person to discover that the World was round? Who was first to navigate it? Who the first to leave it to reach the Moon? Did Persians invent Paradise? Did the Black Death help to develop the printing press? Did Indians invent the number zero? Did the Chinese come up with the idea for the first Earthquake detector? The words we say, the things we use and even many of our ideas are the fruits of philosophies, inventions, and historic facts that took place in other cultures and in other times. Thanks to that legacy we reached civilization. The Diary of History offers children the possibility to explore in a fun way how those times were, since knowing them is a big help to conceive new ideas to invent a better world."
