1. Mount Vesuvius erupts and buries the Roman city of Pompeii 79

   The famous 'bodies' of Pompeii are plaster casts: excavators poured plaster into hollows left in the ash where victims' bodies had decayed.

2. Isaac Newton publishes the Principia, laying out his laws of motion 1687

   The Royal Society couldn't afford to print it — it had blown its budget on a lavish history of fish — so astronomer Edmond Halley paid out of his own pocket.

3. Charles Darwin publishes On the Origin of Species 1859

   The entire first print run sold out to booksellers on the first day. Darwin had sat on the theory for some twenty years before a rival's letter forced his hand.

4. The Titanic strikes an iceberg and sinks on her maiden voyage 1912

   The lookouts had no binoculars — the key to the locker holding them left the ship with a reassigned officer in Southampton.

5. Humans walk on the Moon for the first time 1969

   The Apollo guidance computer had less processing power than a modern pocket calculator — and alarms from it nearly aborted the landing.

6. NASA's Curiosity rover lands on Mars 2012

   It was lowered to the surface on cables by a hovering rocket-powered 'sky crane' — a landing sequence engineers nicknamed the 'seven minutes of terror.'
