1. Construction begins on the great stone circle at Stonehenge 3000 BCE

   Its smaller bluestones were hauled roughly 240 km from the Preseli Hills in Wales — how Neolithic builders moved them is still debated.

2. Martin Luther publishes his Ninety-Five Theses, sparking the Reformation 1517

   Thanks to the new printing press, the theses spread across Germany in about two weeks — arguably history's first viral document.

3. 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.

4. Abraham Lincoln is shot at Ford's Theatre 1865

   General Grant declined an invitation to join Lincoln in the box that night. Booth, a famous actor, knew the play well enough to time his shot to a big laugh line.

5. Alexander Fleming discovers penicillin in a moldy petri dish 1928

   Fleming found the mold after returning from holiday to his messy lab. He later said he hadn't planned to revolutionize medicine — 'but I suppose that was exactly what I did.'

6. Larry Page and Sergey Brin found Google 1998

   The company started in Susan Wojcicki's garage, and its name is a misspelling of 'googol' — the number one followed by a hundred zeros.
