The Christian Science Monitor reports that there are over 100 books in print whose title includes the phrase "That Changed the World." The most recent is "Gunpowder: The History of the Explosive That Changed the World."

Other titles:

• Cod: A Biography of the Fish That Changed the World
• El Nino: The Weather Phenomenon That Changed the World
• Model T Ford: The Car That Changed the World
• The Pill: A Biography of the Drug That Changed the World
• The Twist: The Story of the Song and Dance That Changed the World
• Mauve: How One Man Invented a Color That Changed the World

Some of those books considerably overstate the importance of their subject; but among the 100-plus world-changer titles there is one that lives up to the hype.

• The Weekend That Changed the World: The Mystery of Jerusalem's Empty Tomb
