'Here's your chance to learn and enjoy Big History in a slightly 'deranged' romp.' Dr Karl Kruszelnicki, Australian science communicator, author, and populariser Lightbulb Moments in Human History tracks humanity's big ideas and the eccentricities of those who conceived them. Along the way you'll find answers to questions such as: Why did the Sumerians have temple prostitutes? Just how psychotic was the God of the Old Testament? Why did parents in ancient Greece encourage their young sons to take older male lovers? And what on earth inspired the Mayans to have tobacco enemas? Funny. Irreverent. Never boring. This is not the history you were taught in school. Scott Edwin Williams' Lightbulb Moments in Human History engages, entertains, and provides hope that while times are tough, we're not all going to hell in a handbasket.
