In my 2010 book, What's the Big Idea?, I took a look at some of the most important and influential inventions in the history of the world - from the point of view of kids. What was more important - TV, or clocks? Cars, or toilet paper?
Many of the key inventions we rely on today had roots in earlier inventions (like the clock). We take those early items for granted, but without them, we wouldn't have many others. For example, that clock is at the heart of many of our best-loved tools and toys: televisions and computers, airplanes and cars, bicycles and (ahem) school.
The first schools can be traced to Mesopotamia, where scribes needed to be trained for another big league new invention - written language. Mesopotamia, in fact, was home to dozens of these life and culture-changing innovations. (Can anyone say "beer?")
