Take a lively, sweeping look at some of the most important light-bulb moments in the development of inventions. Find out how one idea often led to another, and revealed something new and exciting about our world. How ancient lighthouses led to 3D movies and 5,000 year old writing led eventually to the internet, roman watermills to flushing toilets and dug-out canoes to space exploration. Take this amazing journey and discover...

• why moviegoers found Cinerama so exciting they screamed
• Ada Lovelace, the first computer programmer and other great
• female inventors
• which code took 267 years to crack
• fizzy drinks were sold as brain tonics

...all this and so much more, packed into a trail of discovery with brilliant writing and humorous illustrations. We haven't forgotten the daft ideas either (spectacles for horses, why not?) and wayward predictions - um, the end of the Internet was going to happen in 1996... (the guy ate his words, literally).
It is all really fascinating stuff
