1. The Great Pyramid of Giza is completed for Pharaoh Khufu 2560 BCE

   It remained the tallest human-made structure on Earth for about 3,800 years, until Lincoln Cathedral's spire topped it in the 1300s.

2. Cleopatra, the last pharaoh of Egypt, dies 30 BCE

   Cleopatra lived closer in time to the Moon landing than to the construction of the Great Pyramid — the pyramids were already ancient to her.

3. Joan of Arc is burned at the stake in Rouen 1431

   She was about nineteen years old. A retrial cleared her name 25 years later, and she was made a saint nearly five centuries after her death.

4. James Watt patents his improved steam engine 1769

   Watt also coined 'horsepower' as a marketing tool — comparing his engines to the draft horses customers would be replacing. The watt unit is named for him.

5. Dolly the sheep becomes the first cloned mammal 1996

   She was cloned from a mammary gland cell, so the scientists named her after Dolly Parton.

6. Steve Jobs unveils the first iPhone 2007
